Xtreme Twinmos Memory!

[setyotomo]

Can you post a picture of the label that is on those "value" sticks. Or at least provide the TM product codes? Are those the same sticks (non SP) that newegg has in stock (the regular PC3200 dual-packs).

How does the price on those compare to the SP?

here you go :toast:

about the price , m.tec 1gig about $50 cheaper than SP :rolleyes:
i think you can get it in US more cheaper..

hmmm the hard part is : what should i do with my SP then? :hehe:

[Negative Design]

can someone please tell me where I can buy Mtec.

[setyotomo]

i think its not important which one you should get (m tec or twinmos relabeled chip), since they are both "value" line from twinmos.. the important think imo is week of production.. but again it may vary alot (but at least they (512x2)can do 250 2-2-2-x 1T with cheap price)

if you can hit >250, i think it would be a bonus from twinmos :p:

[Shroomalistic]

newegg has the speed premiums back in stock, 73 in stock right now. About time they ordered a bunch

[situman]

just when demand might be slowing down.

[EMC2]

Problem in the states is a fair amount of the value line is the sheep stuff (baa-a-a-a-a-a-a-d), not the AA4T :(

Egg has been ordering that much, that were just going really fast ;)

ooh ok,I thought you said Mtec was cheaper then UTT.

on another note,who here uses A64 memtweaker? by goddhor,I'd like to know if the 183 ram option is legit or 3MHZ too high...thanks :)

[Chivalry]

hmm.. any ideas the kind of speed u could hit with only 3.1 volts? haerd a few ppl saying there may be probs with the stability of the ultra-d DFI boards when u switch over to the 4v max ram volts.. wondering what i might hit if i stuck to the 3.1v max :/

[Negative Design]

Wo0t! Fixed my 3.3V issue and now I'm flyin at 260 2-2-2-8 prime/memtest stable @3.45

But I'm only gettin 4000 bandwidth my BH5s would of killed this score...I must be doing something wrong :(

And what do you think of these?
More good UTT or really more BH5 like overclockers.de says?

I don't get it

1*512 works flawlessly 265 at 3.6v
2*512 errors memtest #5 why ???

weird errors at 0.0MB/0.1MB/0.3MB ???

damn it :(

so much about CBBHD... :(

So time to sell them ???? I really want some 1:1 300+ capable ram with 2*512.

The problem isn't the RAM, it's the cpu memory controller. :)

[TEDY]

maybe should raise vcore a little for 265*9 i had around 1.3-1.325...maybe bump to 1.4v ?

can't be memory controller cause before TWINMOS i had KHX3200/256*2 BH-5 which i ran them ok 270 at 3.7v!

Maybe it can't handle the 1Gb.

[cartmanea]

I had the same type errors in my NF7-S, 0.1, 0.3, 0.4, etc when I'd do dual channel above 235 fsb. It can do single channel up to about 250, so that is the on board memory controller then? Any way to beef it up? Chipset and memory voltage seems to make no difference. :(

[enok]

@ dutchman.pt , if they say PN code ends 1A4T... then it's BH-5 UTT. :)
@ TEDY , venice! ;)
@ cartmanea , how much vdimm are u giving them on DC and with what timmings?

[TEDY]

enok just bought damn CBBHD...costed me 190$ :(

[enok]

:( u deserved that tictac's slap smilie!!

Never noticed you used such low Vcore Tedy :am: Would never suggest higher than necessary, but you could safely try 1.6V (have a CBBHD 0450TPCW in the test bench that runs 24/7 and gets severely abused that I run 1.6V on, no prob)

Got some AA4T Twinmos SPs myself, but i'm experiencing cold boot problems. Can't POST @ 240 2-2-2-5 3.2v! If I set ram to 200Mhz then let it power up, the next reboot i could now POST and even memtest stable for 12 hours @ 240 2-2-2-5 3.2vdimm! Could this be a BIOS issue?

Whoa man, that's it. Blame it on us because you can't get your RAM to run at what you expected. That's the way to go. :thumbsup: :rolleyes: :rofl:

I honestly hope that you post more crap like that in the future. At least that would shorten the lifespan of your account here. :D

Otherwise, you could try it the way it's meant to be, edit out what you posted above, give us some system specs and perhaps we can assist you in getting the RAM to perform, in case it's not really bad/damaged.

Anyway, think before you post. This would make it easier for us and for you also. ;)

[uwackme]

Send it back, it'll end up in the "refurb" section.... more good ram for US cheap.... seeya.

hi, i'm new here. i've bought in poland 2x 512mb twinmos (non sp) like this (http://img174.exs.cx/img174/1083/winbondutttwinmosfrontbig6ul.jpg), at the label there is aa4t (so should be ch5), but cpu-z shows me 4 last signs: cad(t) (http://img174.exs.cx/img174/5013/myramcpuz1sv.jpg)- (it mean's they have powerchip die). what to believe ? is it possible that spd is bad programmed ? or i have bad labels on the ram ? sticks do memtest with no probems 8h at 250 1t cl2 2 2 5 2 7 15 @3.6V but ocasionally have blue screen/reset in win xp. have anyone know what's going on with these sticks ?

If they were the CADT chips, it would be very, very unlikely you'd be able to even boot at those memory settings. I'd say they're UTT chips. The BSOD/reset could possibly be caused from many other things.

[muzz]

Well I just got a 2x512 kit from Newegg, I did NOT get the SP, just the regular(TMll400/1GB).
They are 05094 TMD7608F8E50D AA4T, but they are NOT on the BP pcb ( as stated by Alonso, AOA=BP and A8A= KG 6633, which is exactly what is printed on my PCB's).
I also just got a shiny new DFi Ultra-D, so as soon as I get a PCI-E VCard ( If I had known the EGG was delivering today I would have gotten 1 on the way home... DOH!! A day early).
I'll let ya'll know how I make out with them,

[muzz]

How 'bout these??

[Choya061]

bought them today, tested for 2 hours. What do you guys think?

data on the IC's are

TWINMOS
04514
TMD7608F8Ε50D

The third pic shows that the 166multi works just fine!

will post a pic of the Chips later (now they burn in hell... eeeer my PC)


My setup is

Winch 3500+
MSI Neo2
Twinmos DDR3200 rated cl 2.5 (LOL)

----------------------------------------------------------------


OK So far these are the things we have to look for for those chips!


DIMMS Found With UTT
-----------------------
(*) Twinmos SpeedPremium (04464 production week,a 4 at the end help too)
(*) Twinmos\Twinmos Twinmos\Mtec chips (cheap ones) (04514 ,same as above)

Make sure if you can take a look at the chips of the RAM that there are
---------------------------------------------------------------------
(*) Two Dots marking
(*) Metal Dots (two in each side!)
(*) AA4T (not AADT)
(*) week 0xxx4 (the ending 4 is winbond chips)






AND THE OFFICIAL TWINMOS CHIP/RAM GUIDE!

http://www.xtremesystems.org/forums/showthread.php?p=774504#post774504


Ok I have the same Data as my man here, nice info by the way, short simple accurate, but it just doesnt get better then this. These Twinmos TMII400/1GB and any other with the chipset specified above are like a bicep the more u work it the bigger and stronger its gonna get. I have AA4T=CH-5=UTT, when i got them i couldnt get passed 200 FSB SPD Timings, now after burning them in 250 FSB 2-2-2-5 3.3 voltage (no mods). There is a process for this that I will specify shortly and needs some attention and patience.

1. Set memory voltage to 3.3V
2. Set FSB to something high but not too high, e.g. 230 FSB
3. Run memtest86 and loop "test 5" for a few hours

If you get no errors at your this speed, increase FSB, all the way until you start getting errors. When you do, continue to loop "test 5" for hours, the errors will decrease or will be less frequent, soon enough they will magically disappear all together. When this happens, increase the FSB and try again.

4. About the errors... a few is ok, but not a thousands. You want the ram to be forced all the time, and too many errors, the program goes into subroutines to log them instead of jogging the ram. So a "few errors"...10-20-50-100 is ok, not not K's. I liked 10-20 max PER LOOP of the test. The thing is, when errors are found it takes a break to record the tally, so the less errors u get the better.

5. The idea of keeping the error rate low is that the program will take time away from hammering the ram to "tally" the error, and the idea is to hit the ram as hard as possible, so try to target the FSB at the point where errors start but not so high that ALOT of errors occur (as this would take away from the overall effect we are trying to acheive...(beating the ram senseless).


6. For burn in its not required to set it to the highest voltage possible. Instead, and this is confirmed by OCZ, set the Vdimm to 3.2-3.3V and run it in memtest at as high an FSB as it will run without getting more than a few errors on a pass. Now at that FSB point, give it 24-72 HOURS of burnin, keeping the ram cooled with a fan blowing on it. Hopefully the ram will "improve" over time and the errors will reduce/disappear. Try increasing the FSB a couple Mhz every say 4-6 hours, and continue burning.

This info Was supplied by Marcus d that did an outstanding job getting this info.

I will add one more thing, my process was different I used all tests and never got errors on 5, just on 8 and seven, I think it my be different for every one, pay attention to the first pass so that when u see the amount of errors write it down and compare it to the number of errors u got on the other passes, and ull see how the start decreasing.My first pass had 177 errors, second 143, third 90, fourth 10, fifth none :D.So try it and see if it works for u. Ill post pics later so that u can see my results. :toast:

If ur thinking why I havent pushed them more, ive just been plain lazy, i just got World of Warcraft and im hooked, ill try higher and post my results when wow fever dies out

[Toro 45]

I have a pair of the aa4t chips and can't break the 240 barrier, I've gotten up to 238fsb 3.4V. 2-2-2-8 . Also I had to bring my chipset voltage up from default of 1.6V to 1.8V to hit 238. The chipset heatsink runs very hot even at 1.6V, anyone running the nf3 chipset voltage at 1.9V with the wimpy heatsink? I'm a little hesitant to run 1.9V on it.

I have an 80mm fan blowing on them and a 80mm blowing up towards my chipset. I'm testing at 2-2-8 2- and the rest on auto, I have tried 2-2-10- 7-15(the rest on auto) with no improvement on overall speed.

Seems like my chips are a bit stubborn or I'm overlooking something, any ideas? Also I adjusted the 3.3V pot on my Forton to 3.6V to hit 3.4 on the Vdimm.

[enzoR]

did you try 2-2-2-5?
try 3.5v on the ram and burn them in. should get you atleast 250

[Toro 45]

did you try 2-2-2-5?
try 3.5v on the ram and burn them in. should get you atleast 250 Won't boot at 2-2-2-5 3.4V I havn't tried 3.5V but it looks like I might have to. I've been buring in at 231fsb 3.3V 2-2-2-8(the last 20hours)

I adjusted my 3.3V pot by watching the bios setting and was told the onboard monitoring is not that accurate, so I want to check it with a tester. I borrowed a Fluke 7-300 tester and I want to see exactly how much voltage I'm getting to the ram.

I have never used one, is it as simple as sticking the red probe into the ram slot to get the Vdimm reading? What about the black probe? Not to worry, I don't plan on using it untill I get a good qualified answer.

dont stick the probe in the mem slot. black one has to be grounded preferably to the case and use the red one to check the mosfet closet to your ram. Thats usually where its at. Make sure your voltage meter is set to voltage and not ohms or something. That can cause major problems.

[Toro 45]

My meter just has on on/off button and says "Automatic Selection,VAC,VDC,OHMS. no individual options.

Now I just need to figure out which mosfet it is, I just saw a picture of my board yesterday and they were discussing this very same procedure. I thought it was on this thread. hmm..

Edit, I think I found it it's black and says Richtec on top of it with 5 silver bars/pins connecting it to the mobo, do I touch one of the bars/pins or on the top black part?

Thanks for the help, I really want to be sure how much volts I'm using before I go to 3.5V on this ram.

[zt_lee]

any body oc the 2x256 twinmoss 256?

[Formann]

Got a pair of Twinmos Speed Premium 512mb BH5 today.

Buning as we speak.

So far im at 251 2-2-2 3.36v memtest stable. 3.36v is max tho. 3.45 puts out some errors. Need to burn them in some more.

At 3.36v the mosfets on my DFI is 15-20c cooler than with TCCD @ 2.9v .. LOL.

TCCD draws a massive amount current compared to BH5. Diddnt think the difference was that big.

[cartmanea]

The DFI has a temperature sensor on the vDimm mosfet? Also, are you sure its the new BH-5 or is it just UTT chips?

[Formann]

The DFI has a temperature sensor on the vDimm mosfet? Also, are you sure its the new BH-5 or is it just UTT chips?

Nope.. I put a temp probe on the backside of the MOBO. Right behind the mosfets.

Im prette sure its BH5. Komplett.no got them yesterday, and acording to Twinmos they are.

[uwackme]

Ill prolly grab a set of the BH5's too, hope newegg gets them soon.

Interesting about the TCCD's, running lower voltage but dissipating roughly the same power would equate to higher current, and its the current ... P=I^2R that determines the mosfet temp. So if the design is happy with TCCD's it should be more happy with BH5's instead.

Was curious about how fast 2x 256M of the UTT's would be (though not practical for use, 512M of ram dont cut it) but for benching. Anyone get results for 2x256M UTT... esp on a NForce2 with high Vdimm.

[Formann]

It's because of the way that circuit works.

Using the 5V rail @ 2.8V will build up ALOT more heat from the mosfet than if it were @ 3.5V ;)

Same setup as the DDR Booster.

Never heard of mofets getting varmer at lower voltage. Not the case with CPU vcore, and it feeds from the 12v rail.

My booster gets much warmer @ 3.7v than 3.0v.


EDIT: Did some testing with the 5v setting. 2x512mb Twinmos BH5

mosfets temps

2.88v - 56.6
3.17v - 57c
3.36 - 57.5

To be honest I, expected to se a bigger difference.

Ahh.. switching and linear. Of course. Thanks for pointing that out enzoR :)

Going to test with the TCCD in an hour or so.

[enzoR]

but the CPU vcore circuitry are switching. these are linear. the more voltage they have to step down the hotter they get but dont forget that the higher the voltage the more current the ram draws aswell. for the mosfet stepping down 5v to 2.8v will be like hell. if its drawing from the 3.3v it wont be that bad.

[anilyy]

what is the difference between 44D and 50D?

[J0lle]

what is the difference between 44D and 50D?

Its rated speeds 50D indicates 5ns (1000/5 = 200x2 = 400DDR)
44B in the other hand is 4,4ns (1000/4,4 = 227x2 = 454/455 DDR)

These chips are tested @ spd 225 mhz (ddr 450) by twinmos, afaik

[cartmanea]

They are still UTT, which is untested. 4.4ns is just what they are rated at.

[Skip]

i think the UTT means that winbond didn't do any testing. twinmos probably just rates them themselves.

What PCB are the new Twinmos BH-5 sticks using?

[TEDY]

Jedec i think.

[KwaK]

well twinmos has introduced their memory products here lately . So when I heard that some twinmos rams have the BH-5 chips on them .. i paid their sales office a visit to check it out . Unfortunately , upon my inspection it had the M-tec chips on them and the 512 mb cl 2.5 stick were up for an amount equivalent to 50$ :stick: . Are they any good for overclocking ? Coz i heard someone say that the OCZ VX uses this same chip .. lol :D

[[XC] 4X4N]

any body oc the 2x256 twinmoss 256?

I'm new to the forum and was reading this thread. I don't see any reply's to this, so I will post what I have with 2x256 sticks. Using these a DFI NF4 Ultra-D, I was able to get to 245, 2-2-2-6@3.3v. More voltage did not get any higher. I now have 2x512 at 255, 2-2-2-6@3.4v. :D These are the old speed premium sticks AA4T with 44D chips.

My 2x512 Twinmos SP 44D do 270 2-2-2 with ~3.7v, but memtest has more or less 2 errors/pass, always in the same position, but prime95 passes for ours with this config...
The mobo is a NF4 Ultra D, of course... :D :D

[^don.k's^]

Mines didn't go past 267 without a lot of errors, even at 3,8v , so yours are better :confused: BTW I :banana: you in superpi :D Let's see how will the 0450VPDW goes when it comes to me... :p:

[Lord_RTKK]

Will you sell your 0448 SPAW?? It performs OK, not??
2770 Mhz are a good result tho, and air-cooled, if you mount a watercooling... :rolleyes: :rolleyes:
Mine dont passes from 2700, even with 1,95v :D :D

[gsan]

so, anyone can make conclution that between 1A4T(aka bh5) and AA4T(aka ch5), which one is more o'cable? and also between 50D and 44D, which one is better?

[largon]

@gsan: I'd take 1A4T, BH-die should be better.

[^don.k's^]

Yes, when I see what's that VPDW is capable of, i'll sell it or sell the SPAW, i hope if you buy any1 of them don't go far away than me... :p:

Correos guys would deliver de VPDW this morning at least, Izarmicro sent me on thursday afternoon urgently, but, you know correos... :slap: They are a :banana: guys... :D

BTW you'll get informed how it will go... :p:

And about RL... I know, but i don't wanna change my silence for some extra mhz... :stick:

[Lord_RTKK]

@^don.k's^: Hope that your 0450 will be around 2.8Ghz... ;) BTW, who said that a watercooling isnt quiet?? :D :D

@the rest: where I can find this Twinmos with BH chips?? (in spain or UE with international shipping) I already have a pair of Twinmos SP w/ AA4T 44D chips, but they dont do more of 270, even with 3.9v...

[^don.k's^]

@Lord__RTKK I had one and it isn't as quiet as my actual cooling :stick:

And you have 1A4T in cheeep.de and overclockers.de, maybe a new order?? :p:

penang has stock for twinmoss 1a4t? :slobber: if got just grab it dont hesitate, man...

[b|lly]

What are supposed to be BEST settings for 1A4T (bh5?) for ABIT IC7-max3 ?

They can OC a lot lower then UTT: bh5 : max fsb 250 @ 2.8V (if I higher volts i get MORE errors) but UTT can do 245 @ 3.2.

Maybe I should burn them longer, havent really did it yet...

anyone know where i can get CBBHD winny? I killed my best one and is seeking to replace it.

I had some sp before I got my vx, sp would do 260 np then the vx after about 4 days of burning in seemed stuck at 250, put some sp (ch-5) back in runs perfect at 270 and clears memtest at 265 with 3.3v

You can take CH-5 to 270 but you never tried superpi ?
What other settings do you use ? cpu speed and such.

I think most ppl hit the wall at 260.
Beyond that its 1m superpi only.
Mine still has very few errors at 260 but i can run superpi 1meg a little over 270.

When was the last somebody received TwinMos SP 3200 512mb from Newegg? Looking to pick up another stick since price drop. Mine is 44D just wondering what Newegg has in stock now.

its still the good stuff there, aa4t 44d's

My Twinmos SP w/ AA4T 44D from overclockers.de do 268 2-2-2-6-7-15-2-2-1-1 1T memtest 20 passes without errors at 3.6v.
They also do 270 with 3.7v and same timmings, but I have 2 errors by pass in memtest #5, but it is prime estable anyway...

TEDY i've just noticed on your chips it doesnt say BH5, but on mine they do :confused:

At least that will add $$$ to the value, if i sell them

[fareastgq]

I still don't think there's going to be a damn bit of difference in the chips at high volts with 2x512 sticks... ch-5 vs bh-5 I mean, someone prove me wrong, I would like to see better results from bh-5...

[cartmanea]

But the BH chips will do 2-2-2 at lower voltage than the CH since CH really likes 2-3-2 and not 2-2-2.

[HousERaT]

so basically they perform the same at high voltage but bh has the edge at lower voltage? My AA4T sticks will do 250 1.5-2-2-6 with 3.2v. This is just as good as my bh-5 (Kingston HyperX).

[xenolith]

But the BH chips will do 2-2-2 at lower voltage than the CH since CH really likes 2-3-2 and not 2-2-2.

Are you referring to the old BH-5 and CH-5 or the new UTT's?

That may have been true with the old dies, but there's lots of UTT-CH that's hitting 250+/3.3v/2-2-2. :confused:

[cartmanea]

When I say UTT does better at higher voltage I mean over 3v. UTT is untested CH chips, there is also new BH in production. So, UTT still performs like CH-5 did, at lower voltage it can only do 2-3-2, but give it 3.2v+ and it will do 2-2-2. Granted, they may have made improvements since we are seeing 250+ fsb, but A64 is definitely helping there. I had some SP UTT and it topped out around 245 at 3.3v on my NF7-S.

DFI nF4 Ultra-D w/3000+ winnieDual channel and memory controller issues aside, seems like the individual test are no better (maybe worse?) than the average Twinmos SP 3200 512mb (CH) stick results. I was expecting better from BH. This is not encouraging. :( 3.5v seems like plenty of vitamin V.

[RacerX]

Yup, agree with the poster above. I have a TwinMos SP UTT stick supposively with ch die and does 260htt easily with 3.5v. Haven't really burned it in yet but not sure if the ch burns in like bh die. Should have a few more sticks of AA4T from Newegg in a few days. Will post my results.

[Shroomalistic]

well they did say originally that ch-5 was supposed to better bh-5 but the original process didnt go to good. Now they perfected the process and ch is really better than bh. Now we just have to wait for DH moduals.

[Minstadave]

Just burning my Speed Premium BH5 in at 245Mhz 2-2-2-5 3.5V, at which it is 20 passes of memtest 5 stable. It wouldn't do 250 out of the box at any voltage, and I get errors using 3.6V or more, hopefully burning in will sort that.

Looks like the CH5 might be the better bet.

[[timko]]

I got my two sticks of 1A4T as well today, and it definitely says BH-5 on the chips. I decided to put them both in at stock timings, stock fsb and stock voltages (2.5-3-3-8 , 216Mhz , 2.7v) just to make sure that they work at all and I get lots of errors in memtest #5. I even upped the voltages and relaxed the timings but still errors :( Surely it doesn't need burning in to work at SPD settings right?

Did anyone else bother to test at stock first before overclocking?

Note, on the same PC I have just taken out some TCCD that ran 100% stable at a much higher FSB!

Ps, Minsta, glad to see you've taken a brief timeout from your dissertation to get us some results, yours are looking good - unlike mine :( Also, I've rated your review over at Komplett "useful" :)

Same problem here. My sticks need 2.9v to run 216Mhz SPD. Really disappointing. Shame on Twinmos :mad:

The legend is back? Yeah.. right :rolleyes:

[chester]

timco cool.i been getn flack from thge hardcore girls here.I get errors at 200 fsb.I should burn it like most do then send it back,but i dont do that.I take whats given me,and live with it.This is the slowest mem i have ever bought,but some peeps claim to get 250+fsb with 2-2-2-5 timings.It could be they sell this mem and hand picked the modules.I myself would love to get a pair of 512 that do this.If u buy these sticks from twinmos get the cheaper ones as u most likely will find they "suk".my offer tp prove this still stands .Send me ur 255 to 270 fsb and i will send u mine.Im lucky to get 200 fsb 8-4-4-2,and still error.pfff twinmos suks hard!!!!!!!Good fer ya

[[timko]]

It's good to hear that's it not just me so far then.

Well, I'm going to leave mine "burning in" at 215Mhz (yes that's two one five) with 2-2-2 timings overnight at 3.2v and see if things get any better :(

[uwackme]

With no sig's I have no idea what you are running them on or at what settings...complete settings.

If they are normal un-redesigned BH5 then they will act like BH5. So in NForce2 boards they will suk azz.

Ok, here's my setup BEFORE I put in the Twinmos...

NF7-s v2.0 with NO wire mods of any kind.
Manta Rays D26 XT CPC On (1T)
XP-m 2500 IQYHA + SLK900a
2 x 512Mb Patriot XBLK (TCCD)@ 2.9v and 2-3-3-11

...and here's a pic of it running rock solid at 8mb SuperPi 238Mhz FSB (can also do 16Mb and 32Mb and also hundreds of rounds of memtest #5 error free but I didn't get a shot of those)...

http://img200.exs.cx/img200/5615/timko8mb7272io.jpg


When I switched out the TCCD and replaced it with the two sticks of Twinmos 1A4T BH-5, I set the timings to SPD as advertised -> 2.5-4-4-9, I set the FSB to stock for the RAM which is 216Mhz and put the vdimm to 2.9v... and these are the only settings I changed. This results in memtest #5 multiple errors :(

So as you can see, the rest of my rig can do a higher FSB with absolutely no issues with the TCCD RAM so why can't this BH-5 operate error free at a lower FSB?

RMA Time?

[uwackme]

Timko, I've tested 5G's of BH5 and 1G BH6 and none of it will run for shieeet in MY NF7-S....with Vdimm Vtt Vdd mod's!!! Stock NF7 is even worse. But the UTT does 245Mhz 1T 8,2,2,2.0 on the SAME board.

I have to burn the CPCoff bios back into the board when I want to switch back to CH5/BH5 sticks. Using D26 MantaXT cpcon and cpcoff versions.

For you....

First, it NEEDS the CPCoff bios. For some reason BH5 almost never ever runs 1T on the NForce2 chipset. Second its gonna need voltage. CPCoff it will do 200Mhz+ 11,2,2,2.0 2T @ 2.9Vbios. But to shine on NForce2 its gonna need TheVolt and it will never shine 1T on NForce2.

On an A64 board the results will be much better, 1T, lower Vdimm, etc.

These UTT/VX/SP sticks are a different breed and shine 1T high FSB.... but again NOT on a stock board, you gotta get to 3.2+Vdimm to make them work on a NForce2.

So confirm 200Mhz 5,2,2,2.0 with CPCoff 2.9V first, if it still screws up consider RMA.

[cartmanea]

Not entirely true. I had 2x512 Mushkin Promo Build BH-5 that did 225, 2.9v, 2-2-2 on my NF7-S with both Abit bios and modded bios, all with CPC on. The loss in performance from going CPC off needs an extra 30 MHz or so to make up for it, not worth it just to say you have higher fsb.

[largon]

The only real BH-5 I had was Kingston HyperX 2x512MB they did 245 2-2-2-x 1T DC 3.3V on DFI nF2 UI.

@chester: There is no such manufacturer whose every single product they sell works without fault.
You happened to get a faulty pair/stick. No point in wailing about them. RMA them.

My 1GB of TMSP CH-UTT did 250 2-2-2-11 1T DC on DFI nF2 UI @ 3.3V. On current A64 they they freak out in Memtest: 20 rounds of #5 errorless then BAM! 30 errors in single pass. Mostly even #2 & #3 do ~kazillion errors. (BAAaad A64 3k+ CBBID0505) Edit: Hah! Got them stable! tREF is a magic timing.

Guys, just received 2 more TwinMos SP 3200 512mb week 0506 44d. I must say I truely impressed with these $55 dollar sticks. So far one stick burning in nicely at 260htt with 3.35v, passed Superpi 2m with first boot.

PCB is still KO-6633. These are more consistent from stick to stick compared to Mushkin blue it seems.

Now lets see what 3.5v gets us. :banana:

[Toro 45]

RacerX, where did you get your TwinMos SP 3200 at?

[sparkie34]

RacerX, where did you get your TwinMos SP 3200 at?



Newegg I'm sure. :)

[RacerX]

yup, Newegg. Seems both sticks maxing out around 263htt no matter what volts. Noticed I need to increase vdimm to atleast 3.45v as it decreases while stressing or buring in the ram, go as low at 3.3v which isn't good. Need to replace the pot on my booster or go with OCZ Powerstream PS for more stable volts.

Tell ya the truth if my cpu didn't have such a POS memory controller then I would be more happy with 300htt slightly looser timings then 260htt tight.

[Toro 45]

So your buying the individual speed premium sticks, have you tried the Twinmos dual packs from Newegg? My dual pack doesn't perform nearly as well as your speed premiums(237max) I was thinking about picking up the Mushkins but guys are really getting inconsistant results with them. I think I may have to try a couple of the 512mb speed premiums, what timmings are you running with them on your nF3?

I just noticed your using a DDR Booster, did you mod it so you can use 2 sticks are are your results from always running one stick and the DDR booster?

[largon]

Got my week 48 Speed Premiums stable (http://www.helsinki.fi/~llounent/9x250.png).

[burningrave101]

Has anyone overclocked these on an Athlon 64 3500+ Clawhammer? How well will it perform if i install 4 of them in a DFI Ultra-D? I guess they will default to DDR333 speeds but am i able to run them any higher? How safe is it to run 3.2v-3.4v for a long period of time without added cooling for the RAM?

[cjoe]

Just received an unlucky set of AA4T/44D. Neither stick will post at 200FSB 2.5/3/3/9/2T @ 2.9V or 200FSB 2/2/2/5/2T @ 3.2V. Individually they will post at 3.3V but they are not stable. Both sticks will produces thousands of errors in memtest86.

Looks like I need to RMA the two sticks.

Anyone have any suggestions?

BTW: I swapped out my NeoPower 480W with a Fortron Blue Storm 500W because everyone was praising the Fortron so much and disparaging the NeoPower as over-rated. However, I seem to get more memory errors in Memtest86 with the Blue Storm. Do power supplies need to be burned in also? Did I get a bad PS from Newegg? Strange. :confused:

What platform are you on? Intel? Amd? Give us some info.

[cartmanea]

They Neo probably had right near perfect rail values since Antec PSU's are very good at regulating voltage. The Fortron might be undervolting slightly on the 3.3v or 5v rail, whichever is used for Dimm voltage on your board.

[cjoe]

Yeah, you maybe right. But I still think that the Twinmos is bad irregardless.

I'm a little disappointed by the Fortron PS also.

Need to burn in new Mushkin. Seems okay @ 220FSB 3.2V 2/2/2/6 1T 1:1.

GSkill LE stable up to 290FSB 2.8V 2.5/3/3/6/9 1T 1:1. OCCT & S&M still burning in.

I'm going to swap / test memory & power supplies.

3.2 isn't really enuff to run twinmos at 2 2 2, I've gotten errors running 3.2 volts also whether it was 200 fsb or 260, but at 3.3+ they are flawless. after some burn in, they are really nice, (assuming you didn't get crap in the first place). They should be able to do 240 fsb at least for the pair, if your lucky, they can do 260+ with the pair, 512's now I'm talking about, not 2x256, heh.

To clarify, you may have cherry sticks, but for the most part, within the mean of supply, they cannot run 2 2 2 with only 3.2, or everyone would be reporting that they can run 3.2 volts at 2 2 2 flawlessly. ie: 3dmark/memtest/prime stable. Within the whole range, there have been sticks that simply cannot even boot with stock stable, and there are sticks like yours, lucky you :p:

goto to love that tvtorrents, i know I do :toast:

[largon]

I noticed my Speed Premiums very dependant on some timings, for example tREF@ 3120 or 4672 they just couldn't do 230 even 3.4V. Changed tREF to 1168 and BAM! 250MHz (2-2-2-5-7-15-2-2-1-1-1168-1) (http://www.helsinki.fi/~llounent/timings.jpg) with just 3.2V - no bandwidth loss with this setting.
That gives 3033MB/s in Memtest 1.51.
Glad I didn't frustrate before figured out tREF's impact on OC.

[cjoe]

Okay. I'll bump up the voltage and set the TREF to 1168.

I'm also burning in my Mushkin Blue Value (Fry's). 8hrs @ 2/2/2/6 1T 1:1 215FSB 3.3V. Memtest86 in general is error free but test #8 avgs 4 errors per pass still. How much burn in did you guys do before the memory became good?

[largon]

144 hours in a row @ 3V + 9 hours with current timings and voltage. :flame:

[cjoe]

Largon: U the man!!! You're right. After setting TREF=1168, Memtest is much cleaner. I'm going to increase the FSB and let it burn for a couple of days.

What is the current prevailing concensus about Twinmos Speed Premiums vs. Mushkin Value Blue? Which one seems be be better in general?

I have the AA4T / 44D SP and BP815 Mushkins (I haven't opened them up yet).

Thanks...

Were you able to run 2,2,2,6 with > 3.3V immediately after purchase?

I can post at 2,2,2,6 with > 3.6V but memtest #8 registers thousands of errors.

My Twinmos SP are stable @ 240FSB 2,3,6,3,7,15,2,2,1,1,1168,1,E 1T 1:1 3.4V. Does this seem normal after 10hrs of burning? Will they continue to improve after more burning in?

I would be delighted if I could achieve 260FSB 2,2,2,6 @3.4V.

[largon]

Bought them (6 sticks, sold 4) few months ago. First month they ran 240-250 2-2-2-11 on DFI nF2 Ultra Infinity with 3.3V. No fan. :cord:
3.3V was top vDimm on that board. Board did actually die just few days before I was supposed to solder the vDimm mod. Had already put it together separately.
Mem fets were just vaporised overnight.

144hour burn:
If I remember correct it was 225 2-2-2-5 @ 3V w/ Memtest86+ 1.51 + 92mm Zalman fan keeping the temps down. Left Memtest86+ running through #1-"8 for 6 days, not a single error.

Guess nobody is able to tell will your sticks improve... who knows, maybe they will, maybe they won't.
Just make sure they don't get fried.

tref 1168 could be working also for WINBOND BH-5 1A4T ??

I have burned my BH-5 stick for 3 weeks.
It improves alot first 3-4 nights after that you gain 2-3 mhz on week.
Last week nothing has happend.
Burning ~10 hours a night.

*edit* Tref 1168 was real good! (DFI NF3 & 1A4T 1X512)

Been messing with that all day and now it did it right away.

[AdmiralThrawn]

Greetings! I just read this thread because of great interest in BH-5 memory. I used Mushkin Lvl.II with "real" BH-5 chips until today. I ordered two 512MB TwinMos SpeedPremium DDR433 stones, rated at 2.5-3-3-8. I'm using an Asus P4C800, P4XE 3.2GHz, 3.3VDIMM.

I got 1A4T. The memory chips are labeled "BH-5".

http://www.xin.at/thrawn/pics/hw/twinmos-sp-433/twinmos_speedpremium_433-3.jpg

I got them to run at DDR450 2-2-2-5 stable, tried no other voltages. I'm stuck at that speed anyway because of my SATA RAID-0 Array no being very clock-resistant. (SATA's clock is not decoupled from FSB like PCI).

Frankly, i didn't buy the memory for overclocking, i just wanted to have 1GB of DDR400, that could do 2-2-2-5. And that it does, and it seems to be a real bang for the buck.. =)

[jcollett69]

Hello. New to posting here but have been reading these threads for awhile. I have a question and a comment. First, where are the TwinMOS Speedpremium DDR433's being sold? Does Fry's have 'em cause I have had great difficulty locating them online. Newegg looks to be the only place for the SP DDR400's and they do not sell matched pairs of them.
Second, the comment. I've wondwered what a "lifetime warranty" meant in the memory business. Here is a direct quote from TwinMOS' website, http://www.twinmos.com/dram_warranty.htm

Lifetime Warranty
This warranty applies to all “TwinMOS” labeled modules products (EXCEPT Rambus, Elixir, and any original modules) based on the condition that the product(s) is still manufactured. Any product that has reached the end of its product lifetime (End-of-Life) or discontinued shall not be covered this warranty. The end of a product line will be announced by TwinMOS on its website six (6) months prior to the discontinuation of any product(s).

So, looks like it is a product cycle lifetime and not the product. Not that many here use a piece of equipment for multiple years, (more like weeks or months), but the information was news to me.

[AdmiralThrawn]

Hmm, interesting.. Didn't know that either.

I got my SpeedPremium 433's from cheeep.de, which is a german shop (I'm from austria). Cheeep still has those modules in stock, and so does oc-wear.de. Both Shops sell it as "BH-5 memory".

[cardnut99668]

so bh-5 is better than ch-5(UTT) ??

The new BH and CH ics are both sold as UnTesTed. Hence the name UTT. The "new" bh-5 can usually achieve the low latencies at less volts. Still over 3 but usually don't require the 3.6v the CH UTT usually do. I'd say the UTT in general is a steal right now, especially for $110.

[jcollett69]

Sounds like the SP DDR433 may not be sold in the US. Can anyone dispute this? I'm theorising that maybe the remaining "old stock" of BH-5's is only distributed outside of the US. Guess I'll eventually pickup 2 of the SP DDR400 parts at newegg. Anyone have good results with these sticks in MSI's K8N Neo2 Platinum (NForce3 Ultra)? I just cannot afford to go PCI-e just yet. :(

[xenolith]

Not exactly. The current UTT-BH is built with the same 0.175um die screen as the BH-5 of yesteryear so there shouldn't be much of any difference between the two. And sure enough, I have a 512MB stick of UTT-BH and a 512MB stick of "old" BH-5, and they both can hit 200MHz 2-2-2 @ 2.85v.

And much of the current UTT-CH can easily hit 2-2-2 with 3.2 volts, you certainly don't need 3.6v.

[cjoe]

I'm one of the Unfortunate ones. Mine only will do 2-2-3 with 3.3 and its still unstable in memtest. I'm still getting 1-2 errors per pass. I'm hoping that with burn-in it will improve. If I change the settings to 2-2-2-x, it will produce thousands of errors.

However, 230-240Mhz @ 2-2-3 3.3V for $110 is still a helluva value.

Did you try to do what largon did and adjust your Tref value to 1168 or do you not have that option in your BIOS? My MSI K8N Neo2 Plat has little in the way of mem timings in BIOS so I do not think I can adjust it unless one of the esteemed members here have a tool to at least adjust the value in windows. I'm trying to remember if A64 Tweaker had it. I thouoght so but the values were not so high like 1168. I think that value is in microseconds and the A64 tweaker values are in clock cycles. That statement begs the question, "How many microseconds in a clock cycle?"

[largon]

@jcollett69: tREF 1168 in A64 Tweaker is "166MHz 7.8µs".

Yeah, I used 1168 TREF. It helped alot but it didn't solve my problems. I can't run 2-2-2 clean with any settings. I spent a lot of time on my DFI NF4 playing the settings. Largon said he spent 144hrs burning in his ram. So, I decided to burn in the memory at 2-2-3 @ 200Mhz 3.3V to see if I can improve the performance. I put the memory into my DFI NF2 LP B and letting it just burn in with memtest.

Most people seem to hit 2-2-2-x pretty easily and scale to 240FSB with 3.4V in DC from all the posts. I probably just got an unlucky set of memory.

[b|lly]

Is there a max voltage limit for this memory? AA4T?

I'm "stuck" at 256 mhz (2x512, DUAL, PAT disabled). And If I try voltage like 3.9 there are still errors.

It's on ABIT AS8 with intel 3.2

[sparkie34]

IMO I think those sticks will top out around 3.6v Any more than that and the increase will be very minimal or actual cause errors.

[jcollett69]

@jcollett69: tREF 1168 in A64 Tweaker is "166MHz 7.8µs".

Thanks largon. Saw that in a screenshot of yours featuring your A64 Tweaker settings. So I assume setting it to 166MHz 1.95 microsecond causes issues?

I think i've hit the wall here. I'll try to burn it a little bit and maybe get a few more mhz...

btw, hipro5 has been running it at 260 mhz ...

[AtomicOnionMan]

I myself have some TwinMOS ValueRAM AA4T Winbond CH-UTT, whatever you guys wanna call them, and after some minor negotiation and swapping DIMM slots about 6 times, I was able to successfuly run them Prime95/memtest stable at 260Mhz 1.5-2-2-7-1T with 3.4vdimm. 260MHz is good, damn good for what I paid for the RAM ($108 :banana: ), but, being an overclocker, I'm never satisfied, so I decided to give thise whole "burning them in" thing a go. So I set it to 265FSB, which gave about ~80 errors per pass on memtest #5 and let it loop for the better part of the afternoon and all night. To my dismay, I came back the next morning to find the number of errors had increase to nearly 800 per pass :slap: I'd say my cooling over the DIMMs is sufficient, hard to think of anything better than 125CFM off of my XP-120 and the ICs are barely lukewarm to the touch so I'm lost :confused: I'm pretty determined to :horse: cause 260 just isn't good enough :D

EDIT: Oh, and I'm new here :D But I've been following this thread from pretty much day one (bought the RAM last week though).

[Toro 45]

I just got my 2 Speed Premuim sticks, hopefully they will do better than my first two of the Twinmoss AA4T Dual pack, they maxed at 3.4V 238fsb 2-2-2-8 I notice they had the 50D and these have the 44D part number so maybe I'll have better luck.

I'm going to start with a nice 3.2V burn in


Edit: Very pleased with these bad boys

3.2Volt = 249fsb 2-2-2-8

[Toro 45]

What voltage did you feed the sticks with and how did you cool them?
Me wonders the same thing?

[pazza316]

3.5 volts 125 cfm 12cm fan! Should be enough cooling same as I used to get 277FSB from BH5 @ 3.7 volts stable!!

[Toro 45]

Agreed, that should keep them cool. Do you have another system to try them in? When you tried them did you reset to default with your BH5 or are you hitting them with 3.5Volt?

I remember reading about a guy doing the same thing, removed his sticks and considered them dead. A few weeks later he dropped them back in and they worked fine.

[pazza316]

Na I am resetingthe CMOS before retrying them! I think they are dead. No other system to try em in. My other systems are sdram!!

I have the same problem as you. My sticks have been running 24/7 at 265 @ 3.4v, cooled with a 12cm fan that kept them cool.
One day, my rig don´t boot up, I cleared cmos, swapped the sticks from slots, and tried them separate. I have found that one stick is dead, and the other is fine. I have to try it in another system, to confirm that it is dead, but I think that it is... :( :(

[cartmanea]

3.3v+ is probably just more than the ram can handle. The ICs are rated for 3.6v, but that doesn't mean any of the voltage regulators, resistors, or caps are rated for those high voltages. OCZ VX uses components rated for these higher voltage levels, thats why you can get away with it with those.

I agree with this guy....

[uwackme]

Yes, One of my sticks has been exhibiting this phenomenon. Runs awesome for weeks, then one day .... BEEEEP. Its one stick. Nothing would "clear" the error. But taking it out, leaving it aside for a few hours while I used a different stick and VIOLA... "bad" stick is back running for weeks flawlessly.

Like some latch-up problem (a problem that can effect CMOS circuits) gets the ram in a locked up state, a long sit with no power and the chips bleed to no electrons and presto its back up and running.

This would be pointing to motherboard signal integrity and power supply (the VDimm circuit) issues. The high voltage, and high current and high speed we are pushing these things too is taxing the rest of the system beyond what it is used to. This isnt a permanent damage issue, just a symptom of poor signal integrity, PCBoard and component quality. The RAM itself is fine, the latchup is occuring probably to UNDERSHOOT on some of the signal lines....ie: instead of a "0" being 0 volts, it was driven lower due to circuit bounce to some -X volts low enough to trigger the latchup, which then freeze's the circuit inside the DDR chip(s) until they are truly turned OFF and all charge is drained away.

This is all speculation, but the symptoms (bad ram miraculously coming back to life) sure sounds like the situtation.

I wish I had a scope fast enough to "SEE" the signals while operating, but that's some seriously expensive equipment...500Mhz dataline data rates would need a 2GHz digital storage scope to properly sample.

Above all dont panic if the BEEEEEEP pays you a visit.

http://www.newegg.com/app/ViewProductDesc.asp?description=20-218-062&depa=1

and guess what. They are NOT winbond chips. Only have one dot and bottom right. So guess not Twinmoss is NOT giving UTT anymore for value chips. This mems perform only 2.5-3-3-8 @ 235. Won't go any higher even after burning. Won't matter the juice u give, won't pass 235 htt. Burned them for 2 days. Same thing.

So be aware. Don't buy the new value form Twinmos. Btw here stays some info:

[setyotomo]

i got twinmos mtec "value" 05094 AA4T .. about 20 sticks about 2 weeks ago, and its all good.

what you got is 0508D .. thats not good..
so it's still random thing from value twinmos..

@unwackme : that's a great information! thanks.. theres a friend of mine got the same problem, i'll tell him right away.. :toast:

[cartmanea]

Those ones never were guaranteed UTT, its the Speed Premium that is.

Yeah I got the same ones from Newegg and they seem to top about about the same as yours. I took a gamble on the budget modules, but I cannot really complain since it is for my backup rig anyway and it was only $103.

[Bennah]

Totaly lost track of this thread.

Ive got 4x 256mb sticks of Twinmos SP AA4T. They all do around 250 range DC 2-2-2-5 @ 3.3v. Havnt tested them further. Havnt had the DFi out of the case yet, to add 'good' cooling over the 4vdimm mosfet ;) Will do later on when I get my xeon rig up and running.

Anyways, so AA4T is UT CH-5? 1A4T is UTT BH-5?

Does the 1A4T come in 3500 SP and 3200 SP flavours?

Was looking around the egg and how about these (http://www.newegg.com/app/ViewProductDesc.asp?description=20-218-062R&depa=0)? chance of being oldskool BH-5 ?

[anilyy]

i got 512x2 twinmos AA4T Hits to 270 2-2-2-5 with 3.4v.

[Bennah]

Got any screenshots to verify that ? verified cpu-z shot ?

[sparkie34]

Correct

3500 SP only


Was looking around the egg and how about these? chance of being oldskool BH-5 ?

No. I hope this helped you. :)

[Bennah]

Thanks Sparkie.

Thought I saw some 3200 sticks being 1A4T when people first discovered 1A4T being the new BH die.

Anyone seen 3500 SP in 256mb sticks?

[Reefa_Madness]

Nope, but these look to be. Just not exactly a bargain by today's pricing. It is however, a brand new retail stick of KHX PC3200 (non A) with warranty. At $240 per gig.

http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=80097-9

[gundamit]

$240? At that price point you might be better off with 1Gig of the "new school" BH speed binned by either G.Skill or OCZ, for about $40(USD) less. Or you could just pick up 1Gig of the CH UnTesTed from any number of places for about $100-$140. If you get 240+ without volts at levels that won't have you posting a message weeks or months later regarding the mysterious death of one of your sticks, count yourself lucky and put the saved money into your CPU or video card budget. :)

I can't justify buying of the new BH/CH UTT since my old Mushkin BH-5 will do 250 at 3.3v rock steady straight through hours of gaming. Still its tempting when I see 2x512mb at very cheap prices.

[mare87]

Sparkie UTT BH-5 comes with PC 3200 SP sticks too. I know 2 guys that have them.

So how do you know it's UTT? my 2x512mb pc3200 was $105 @ newegg and its A4AT and does ~235 memtest stable on 2-2-2-5 with 3.3v

If you have AA4T, then it is the CH5-UTT. Since you are able to to 235, 2-2-2-5, pretty sure you have it.

[HydroX]

well, this is my result in DFI Infinity NF2

only can run SuperPI 1 M :( with vdimm @ 3.7V. But there is no difference between 3.6V and 3.7V because i think my system was reach the limit.

That Kingston HyperX3200 _is_ the NEW BH5. Pop the covers and you'll see new BH5, not the old Kingston relabeled/packaged BH5 chips...D328DW45's.

Everyone is getting on the bandwagon of the new production run.

What I havent seen is 2x512M of the NEW BH5 run through the NForce2 ringer to see if the CPC on/off issue still remains. If they are just more BH5 production then they probably do still suffer from it.

The question becomes... is the new UTT-CH5-VX the better choice for maximum performance (even though it requires high Vdimm) or can new BH5 at lower Vdimm equal the UTT-CH5-VX stuff? Dunno.

Are your claiming that those are new bh die UTT on the KHX at ZZF as opposed to just some old inventory that was located somewhere? I'm not asking this question to argue with you, but just to try to get more information. I've not seen Kingston claim to have a new bh based product available. Did I miss this or are you just speculating that its UTT? Do you have a link to a news release or a product description for new Kingston bh ram? I really think it is just old stock that turned up somewhere. And not that you stated all KHX was relabeled, but for what its worth, all of my KHX PC3200 is original bh-5.

Keep in mind that Mushkin has been selling original bh-5 in their Mushkin Blue dual-packs. They claim that in a recent order Winbond sent them a box of original bh-5, along with new bh die UTT. They used these, as well as some stock that they had for RMA, to produce a batch with original bh-5, then they produced the rest of the Blue dual-packs with the new bh die. This information was posted by one of their reps on several sites.

Again, at $240 per gig there are many other choices to consider. I just saw the earlier post from Bennah asking if the stuff he linked to at the egg was old school bh-5, so I posted that link to ZZF.

[uwackme]

As far as I know Kingston was cleaned out of BH5, and didnt even have RMA BH5's....ie: if you had to RMA a BH5 stick you werent going to get back a BH5 replacement.

So I hardly think some miraculously appeared....meanwhile NEW BH5 has come into the world and suddenly some clearly BH5 spec'd sticks show up... If I were a betting man, I'd bet they were new BH5 based sticks.

Moreover, a quick peak under the heatsink will confirm, the code numbers on the chips will have new date codes. I doubt they would have arranged again for "custom" packaging from Winbond like they did in the past....BH5 HyperX came in a custom TSOP with fewer pins (the unused pins for beyond 32Mx8 chips were deleted from the stock JEDEC TSOP).

But Im not wasting my money buying a pair to confirm. Im sure someone will buy a pair and maybe we'll find out then,

More importantly.... noone has done a NEW BH5 2x512M thorough test to find out if any "improvements" has been made. If not, UTT/VX/newCH5 is a better stick to be using for all NForce2 applications... since 1T operation will work, while BH5 rrely if ever did 1T on the NForce2's. At $54/512M the Twinmos remains an obscenely good deal.

As Reefa_Madness said, Winbond had just some month ago sent Mushkin a shipment of da old BH-5.
Maybe Kingston too got a shipment.

What RAM is better TwinMos UTT WInbond or the new TwinMos 14AT (BH-5)?

[MonkSP]

UTT Winbond is UnTesTed. This means that if it is Winbond is either BH-5 or CH-5. I heard that lately CH-5 is clocking much better then the new BH-5.

[Reefa_Madness]

That may be true, but then I never said that Kingston had new stock, just that someone found a batch of old stock.

So I hardly think some miraculously appeared....meanwhile NEW BH5 has come into the world and suddenly some clearly BH5 spec'd sticks show up... If I were a betting man, I'd bet they were new BH5 based sticks.

A quick peak at Kingston's site will reveal that they do not have any new KHX products listed for PC3200.

http://www.kingston.com/hyperx/products/khx.asp

The only things products that they show are the "A" version (ch-5) and the "U" version (TCCD) and then the 1GB sticks of "no letter" and I don't know what these use. My point is that they do not show any of the 256 or 512 sticks or regular PC3200 which is what ZZF has. For that matter, ZZF has carried PC3000 for the longest time and may still have some.

But Im not wasting my money buying a pair to confirm. Im sure someone will buy a pair and maybe we'll find out then,

More importantly.... noone has done a NEW BH5 2x512M thorough test to find out if any "improvements" has been made. If not, UTT/VX/newCH5 is a better stick to be using for all NForce2 applications... since 1T operation will work, while BH5 rrely if ever did 1T on the NForce2's. At $54/512M the Twinmos remains an obscenely good deal.

Couldn't agree more about the TwinMOS from newegg.




By the way...just saw on another site where one of the guys posted that Mushkin is coming out with a "Redline" named set of PC3200 and PC3500 that are supposed to do 2-2-2 timings...more binned bh UTT perhaps?

Edit:
Never mind about Redline...just saw where he started a thread here as well.

[zt_lee]

I'm new to the forum and was reading this thread. I don't see any reply's to this, so I will post what I have with 2x256 sticks. Using these a DFI NF4 Ultra-D, I was able to get to 245, 2-2-2-6@3.3v. More voltage did not get any higher. I now have 2x512 at 255, 2-2-2-6@3.4v. :D These are the old speed premium sticks AA4T with 44D chips.

o just saw u reply my post :p:

here is my result:
twinmos UTT 2x256

So its better Winbond UTT AA4T than 14AT?

i had a kit that did 260 2-2-2, died on me within 4 days, then a kit that did 240, one stick has died on me. Just complete failure, just bang and the comp wouldn't turn on. Disappointed to say the least, but i will still keep dumping my money into it to find a pair that won't die! :p

[Toro 45]

Skip, what kind of voltage and cooling on those that died?

[Simplex]

Do you think i should go for a pair of

Twinmos Speed Premium pc3200 - confirmed new BH-5

instead of Samsung TCCC or UCCC(single sided)?
Some says the new CH5 is better than the new BH5 but
then another says thats because of trouble with the old
nf2 mb. Anyone with comparable info regarding the new nf4?

[I´m building a system with DFI ultra-D nf4 and AMD64 3000+]

Is it the DFI that is killing Rams ?

Have you read this thread?

Ive got one SP stick that is flaking out at HIGH Vdimm. It will run ok for a while then ....beeeeep. If I unplug it, sit it on the desk for a day, its back to working fine. No issues @ 3.2Vdimm but 3.4-3.5Vdimm triggers this effect.

If you didnt know it, you might think the rams were DEAD.... so those with rams that up and failed...like failed to even post/boot... you may have similar situtaion occuring and the RAM isnt actually "bad".

My hypothesis on this is that it may not be the UTT chips responsible at all, it may actualy be the SPD rom chip that at high Vdimm flakes out and latches up.

Im going to use this stick to experiment.... Ill put a diode or two into the power supply to the SPD rom (the little 8pin gizmo on the end of the stick) and see if lower voltage to the SPD rom while high voltage on the UTT's works fine with no malfunction.

Its not a matter of high errors reported, when this "latchup" occurs the system wont even post/boot with the stick installed. This screams SPD rom malfunction, and the bios flips out since it cant get a response from the DIMM telling it WHAT kind/size/etc ram is installed.....since the bios needs this info to setup the memory controller registers. And we never get to boot if the rom malfunctions.

its the only logical conclusion I can ferret out so far.

It's killing me cause this stick is one AWESOME stick that does 250Mhz in dual channel on NForce2 8,2,2,2,2.0 1T and I want it in action.

This would be one of those things where Twinmos might cheap-out while other makers using the same UTT chips dont, and so we see "failures" fom Twinmos that arent really failures.

Though I have actually had BAD sticks, with 1-2-3 fixed errors in test #1 or #2 or #8 regardless of voltage/settings/etc. These are actual defective sticks.

Thoughts? Anyone with "BAD" "DEAD" sticks please try them out again in LOWER voltage sytem/settings to see if they come alive again.

i had a an 80mm fan directly on them, and a 90 on the mosfet. They were cool to the touch, i had 3.5V running through them. I'm not sure what was killing them. it might be this board for all i know.

[Hemingway]

Okay, maybe some of you seasoned overclockers can give me an answer to these questions:

I have 2 sticks SP 512 AA4T 44D
Shuttle AK37GT motherboard. NO PCI lock, so I'm stick at 166fsb. Voltage is 2.6

In the bios I set 2-2-2-5, but in cpu-z it shows 2-2-2-6. is this a motherboard issue?

I set cas to 1.5 and I got BEEEEP BEEEEEP black screen, had to clear cmos, etc...

So, unable to hit 1.5-2-2-5, did I get crappy ram or is 2-2-2-6 the best I can expect at 166fsb?

I am going to upgrade to A64 system in the near future with a nice, overclock-friendly motherboard...I would like to get 1.5cas but worried that I won't since I can't @ 166fsb.

Thanks in advance for any help or advice

You need to raise your Vmem ;) Also, as I remember that MB did have dividers for the FSB/PCI... use 5/1 divider for above 166Mhz.

One other note: On an A64 system the memory controller is part of the CPU so CAS1.5 is more likely... and on a good OC board much higher Vmem is available than on that Shuttle.

Peace :toast:
