Xtreme Twinmos Memory!

[EMC2]

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

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:

@uwackme

I really wanted to know how the h3ll you got your sticks working in DC and with CPC ON @ 250 with NF2? I am completely baffed. I recently got some UTT ram (dunno whether BH or CH) but i can only maxout at 210 DC with 4 Banks of mem and CPC on. This is only acheivable at high vdimm also around 3.3v. Even if i run 1 stick with CPC on i only get around 215 after that memtest locks up on test5 no matter what voltage, high or low.

Each stick can do 245fsb SuperPi 32m stable with CPC OFF and 3.5v.

Do i need this twinmos AA4T mem (i.e. CH UTT) will this mem allow me to use CPCon

:confused:

Yes, this motherboard has the 5:1 divider, but it is useless above 166fsb. 166/5 =33 Any higher than 166 is increasing the PCI bus to more than 33mhz, which is no good.
What I need is a PCI LOCK, which will lock it at 33mhz.

[EMC2]

Any higher than 166 is increasing the PCI bus to more than 33mhz, which is no good. What I need is a PCI LOCK, which will lock it at 33mhz.

Never had a PCI card or HD that wouldn't push into the mid 40s... when KT266 based boards first came out, many were pushed even higher ;)

[Raybo]

Like MC2 said, I use to run my KT333's PCI upwards of 40 mhz, mostly depends on how well your HD will take it. ( ghost your OS before you really try to push it or else :bsod: )

[uwackme]

Naj,

I've been working on it, tweaking away, for months. Spent a zillion hours on NF7-S before going Infinity. Infinity(LPuB too) has the best Vdimm circuit out there in NForce2-land. Also the NB and SB chips have seperate Vdd supplies, so the NB can get hit harder without roasting the SB.

My Vdd is actually about 1.95V, but the exact Vdd you want varies by the chip you have, only testing will let you find the sweet spot. My NF7-S liked 1.85V....1.825+under or 1.875+up would result in errors at lower FSB memtest#5 than exactly 1.85Vdd.

The Vdimm circuit is great, easy to Vmod too for higher operation. I can go to 3.8V if needed. It's based off the 5V rail, unlike most NForce2's which use the 3.3V rail. Also, I have my 3.3V rail set to 3.5V....since the NB chip uses both Vdd _and_ the 3.3Vrail as power sources, having the 3.3V rail goosed a little seemed to help get that last bit out of the system.

I lapped my NB, sanded with 1000grit paper till it was FLAT...the NB plastic is cupped and wont give best cooling without treatment. I use a Swiftech157 heatsink on it, though a NB1-C would be great as well.

The OCZ Powerstream 520W is also in on the 250Mhz achievement. Also my 2600+ chip is a damn good one, which is critical. On my lapped/polished Alpha8045 heatsink it will do 2680Mhz hitting 55C load. i've got the Vcore and Vdroop mod's installed, as well as the over-current mod which involves replacing 3 SMD resistors inthe Vcore circuit.

Beyond that, its the memory specs in my sig...all the settings are listed. Mind you, I have gone through 7 sets of these Twinmos UTT's....5 TMII 2 SP's... 1 set would NOT do 1T (Cpcon) but would do 245Mhz 2T, 5 sets would do 245Mhz 1T @ 3.4V, and this set Im using does 250Mhz 1T @3.5Vdimm. So it took some digging.

I have 2 120mm intake fans blowing cool air on the board/ram/etc, an a 120mm exhaust. The case is a good one but heavy.

All these things add up, takes alot of tweaking.

I would add, memtest FREEZING is usually due to too low a Vcore setting. I'd try the 1.775-1.85V area when going for the high FSB's. You can always slowly back DOWN once you havefound the memory's max. You can definitely end up with sticks (rarely but happens) that wont do 240+Mhz 1T.

[HydroX]

well, today, i'm testing the twinmos value mtec ( 1A4T ). why the result is so crappy ? in 200 / 2-2-2-5 @ 3.3V, it can't finish superpi, and then thousands error @ 3.6V / 235 MHz. So....why ?


http://img253.echo.cx/img253/2457/2008re.jpg

[jhatfie]

Just got me two 512MB sticks of the Speed Premium. Testing them out so far, 10 loops of Memtest gave me 40 errors at 250mhz (2-2-2-8) @ 3.3v. hopefully some burn in will correct that. Funny thing is that at the same speed, my super pi times did not really drop compared to my TCCD's with 2.5-3-3-8 timings. I am sure there is just some tweaking I need to do on my DFI NF3 250GB.

[NajZ]

@uwackme

Thanks for that, i can understand it takes a lot of tweaking. At least it paid off ;)

Anyway im going to try these sticks in my friends DFI NF4 to see what they are really capable off. I'll get some idea into what is holding me back, mem or chipset.

This is my third DFI NF2 board btw, I already killed 2 boards before. :( They were reeeeally sweet ones as well. This one isn't as good as the others.

I remember you saying that BH-5 can't do DC with 1t but CH-5 can on NF2.
I think im gonna try some AA4T ram first.

[Gray Mole]

I've just ordered a set of the BH5's in speed premium, so next week will test...

All the feedback on both the Bh5's and the UTT ch5's is a lotta help though, nice to see ppl still pushin' at the old skool stuff :)

I'm still using an old set of Twinmos's BH5 in 2X256, and it's running 255htt and cas1.5-2-2-5 with no problems at all, so I'm hoping that I can burn in the new stuff and get similar or better results, with the Brainpower PCB being an improvement over PCB's of old...

Gotta remember, it's still CH5 and BH5 we're playing with, and I've had BH5's in the past wouldn't give me 2-2-2-5 at 200mhz, much less any higher, and My old 3500 ocz CH5 based 2X512 wouldn't stretch past 245 at 2-2-2-5 (3.3v), so into the kid's PC it went :D

Point is, even though the BH5 and CH5/utt on improved PCB SHOULD be a lot better, and the old stuff was pretty wikked, it's still hit or miss what you're gonna get...

I'm gonna see what this new set will do, but my old BH5 has had what? 10,000 hours of burn-in? lol Might take a little while to get 'em going...

Gray

[uwackme]

Naj, I'd give the AA4T's a try, this "new" CH5 based stuff has seriously been improved. I have BH5 that wil not run 1T on any NForce2's at all, but will on A64. The BH5 and NForce2 just dont get along well for MAX FSB except for rare examples.

[Gray Mole]

Yeah, the NF2's had some issues with bh5 and fsb in some cases, but more often issues with high fsb and 512 modules...

The last XP NF2 rig I ran had these same Twinmos BH5's in it, and they ran 245fsb with no problem (NF7 and AN7) Whereas neither one could break 225fsb with 512's unless I turned CPC off, which I'm not all that inclined to do...The DFI board would kill it on FSB, but overall speed was pwned by abit, period...(maybe 'cept for Epox...and LN2 :D )

I can't really see an 'improved' BH5 or CH5 chip being made, or they'd call it something else...An improved yeild, sure, but different?

The PCB I think is where the biggest improvement is coming from...but time and more importantly 'burn-in' time will tell...

I just got my SP today I got the AA4T 05064 44D but why I dont have brain power PCB??

The Twinmos does not come on BP PCB.
Try Mushkin Blue line if you want BP.

[Gray Mole]

I've only seen piccys confirming the 1A4T BH-5 version on BP PCB, this thread http://www.xtremesystems.org/forums/showthread.php?t=50010 confirms that both UTT and BH5 version come on Brainpower...just scroll down to Twinmos...what week/year is that memory? Maybe it's an early version? Week 46/2004 and later are supposed to come on BP...

Gray

[Raybo]

Am I wrong again? :slap:

Sorry if I gave you the wrong information. :hitself:

[Gray Mole]

That's just it, mate, you might not be...

And that raises some interesting questions...

Some are having great clocks out of the BH5 and UTT, and some aren't...Might it be because some of the Twinmos is coming on some other PCB, and some on Brainpower?

Be something to confirm when you get it from your supplier, and when mine comes next week, that's the first thing I'll be checking...

IVE TESTED MY MODULES SEPARATE AND GOT ONE THAT GIVES ME ERRORS @ MEMTEST #7 2.5-3-3-8 2.6 BUT @ 3.0 IS GOOD TO GO, RIGTH NOW IVE GOT THEM RUNNING @ 2-2-2-6/3.4v 200MHz. IM NOT SURE IF I SHOULD RMA THAT STICK TO NEWEGG SINCE IM NOT GONNA BE RUNNING @ STOCK SPEEDS OR VOLTAGE AND SINCE NEWEGG RAN OUT OF STICKS.

[Gray Mole]

Well since you've got 'em in anyway, just set 'em up around stock, and loop test 5 for a couple hours, and slowly come up from there...

I usually go straight to around 3.2 volts or so, get just under the max I can, and run test 5, or just loop the works, until they start to give, but you can break them in any way you like :D

Try to burn 'em in and if they just won't budge, rma...

phew i live in singapore, tml gonna go down to twinmos office to chose the rams
jus a recap, AA4T for the p/n

and the 2 obvious dots, and it'll be done right?

finally can get rid of my hynix dt d43, damn loose timings

btw i still dun understand the 2 metal dots on each side thingy

I also live in Singapore. May I know is TwinMos office open for business on Saturday after 2pm. As I am working office hour and got no time to go to the office. I can go on Saturday after 2pm if TwinMos is still open for business. I tried to get DC PC 3500 Speed Premium 512MB x 2. I went to SLQ last Saturday and could not find any PC3500 SP. TQ

[CarbineBoy]

Just received my two 512 SP sticks from Newegg....
AA4T 44D :toast: :banana: :woot:

Me too, 1) what is this stuff and 2) whats a safe maximum 24/7 voltage?

[Simplex]

The new A64 3000+ Venice can manage maybe something between 2500
and 3000MHz. With a multiplier of 9 that makes a FSB of 275 to 335 MHz.

How high FSB can a SP BH-5 go with higher timings?
315MHz with 3-4-4-8? (just an example)

Is SP CH-5 better in this regard?

Maybe I´d make a new thread out of this?

[Gray Mole]

AA4T is winbond CH5 UTT...

Should be great, but averaging less than 275 at 2-2-2-5

BH5 is 1A4T and seems to be averaging less, but time will tell...

Some are getting 275 out of it, and if you're lucky, you will too :toast:

I'm getting the 1A4T BH5 version, and will post results here...

When you get an idea of what it'll do, post it here

would 3 volts be max for stable 24/7 system with the CH-5? The last thing I need is to fry them working on a big project :nono:

At $115 for 2x512Mb and guaranteed to be Winbond (I called to confirm), it would seem to be pretty cheap insurance over TwinMOS since they have put out different chips SP3200. I realize people have been getting winbond on the SP's lately, but that hasn't always been the case. So, has anyone here tried both and have an opinion on which is best? :confused:

I have been running 3.4v 24/7 for over 3 weeks, no problem. You should get some kind of cooling on them though if you are going to run that many volts. I've 2 80mm fans, 1 on the ram, and the other on the vdimm mosfet area. Plus a 120mm fan from the side panel blowing on the pwm mosfet area.

The chips on those OCZs are binned. They were no good for the VX-line...

[MonkSP]

What do you mean by binned?

[Gray Mole]

chip quality go's through some testing to see what it does, and batches that have had the best samples tested go into the best, and more expensive ram modules...

VX value and VX3200 and VX4000 is a great example...

best batches go to the higher grade memory, not to say that Value won't be good, it's just that odd's are the VX3200 will be better...and VX4000 better still...

Does a brainpower PCB have it written on the PCB ?
What to look for ?
What is B6U808 ?

[largon]

@Ubermann: AFAIK TwinMos has used BP only with NON-UTT chips (Powerchip etc.). Beware!

B6U808 and B6U815 are Brainpower's serials. The serial is written in the upper right corner (http://www.techpowerup.com/reviews/TwinMOS/SpeedPremium/images/Backbeide_big2.jpg) of the PCB.
The best way to identify BP is the lack of visible traces.

Mushkin Blues do have B6U815. Alas, they don't perform so *spectacularly*...

Even after weeks of burn-in, my TMSP 3200 (K0-6633) sucked pretty bad also. In SC mode, one module would do 233FSB 2/2/2/6 @ 3.4V while the other would do 223FSB 2/2/2/6 @ 3.5V. In DC mode, they could not do much more than 200FSB @ 2/2/2/6 @ 3.2V. At higher FSB and higher voltage in DC, they would be stable for 3-5 passes in memtest86 and then produce hundreds/thousands of errors. Overall, they could barely manage 200FSB 2,3,3,10 @ 2.8V. It would become stable when voltage >= 2.9V. Very marginal set of memory. Oh well, luck of the draw.

However, my two sets of Mushkin Blue are starting to respond finally. I was starting to despair because I thought I had purchased 3GBs of bad ram.

Cjoe

[Gray Mole]

I couldn't even run the 2.5-3-3-8 at 200htt with them together...

Awful, really, I was expecting they'd at least run the numbers, and maybe burn in, but if I have to burn them in just to get the rated speed, there's something wrong...

I requested that they replace them with the SP CH5 utt's instead, and I think they're happy to do that...

Yeah, 1 bad GB is bad enough, good to hear the blue's are coming together for ya :)

You tested a lot of sticks. Did you do burn-in on any of those sticks? Sounds like you got a good batch.

To a certain degree, you maybe right because there are a lot of noobs out there. However, in my case and Gray Mole's, I will disagree with you. We just happened to get stuck with inferior memory.

I have two CPUs (3200+ and 3000+ topless) and two PSUs (Antec NeoPower and Fortron BlueStorm 500). I have tried various permutations on my DFI NF4 with all my memories (2x512 GSKill LE @ 300FSB 2.5/3/3/7, 4x512 Corsair XMS XL 240FSB 2/2/2/5, 4x512 Mushkin Blue (Green) @ 250FSB 2/2/2/6, 2x512 Twinmos SP default) at 1T 1:1. The TMSP would just barely work at default setting (an error would showup after every 20-30 passes in memtest). Even after significant loosening of the timings, it still wouldn't work very well in DC mode.

I even tried burning them in on my other rigs (DFI NF2 LP Ultra B, Abit IC7-Max3, Shuttle SN45G, and ECS 875 system) at default settings. They just weren't happy.

Dont take it personal. Seen so many complaining about ohh this stick sux im going to RMA it.
And after some help and trying they usualy get it running pretty good.

I didn't take it personally. I was just trying to describe my testing approach and scenario. I read through all the threads and tried all the tips especially Largon's. Some worked and some didn't work.

My AA4T CH5 K0-6633 would not do > 210FSB @ 3.2V DC mode with tight timings of 2/2/5/2/7/15/2/2/1/1/1168/1 1T 1:1. It would do slightly better with looser timings but it was still unstable at any voltage.

BTW: How did you manage to burn in so many sticks in one week? Did they all get to 250FSB+ really easy? Most of my memories required about 3-4 days per stick to achieve total stability with no errors in Memtest, OCCT, and S&M.

I never burned them, just tested them in superpi and sold them.

[jhatfie]

Doing some further testing on my new 2x512MB TwinMos SP PC3200. Looking pretty good @ 3.2v on my socket 754 setup. Doing 250mhz with 2-2-2-8 timings which brings me joy. They seem to perform about the same as my PQI TCCD's at about 270mhz with 2.5-3-3-8 timings and the same cpu clockspeed. I was thinking that the SP would hold a little bigger performance advantage, but I imagine it could be some tweaking I just need to do.

[cjoe]

I never burned them, just tested them in superpi and sold them.

Okay. Now I understand. Are you equating SuperPI @ 1M testing with total system stability at that FSB?

I can easily run a suicide SuperPI @ 1M at higher FSB in DC but I know the machine is not memtest, OCCT and S&M error free stable.

cjoe

[Ubermann]

No not stable but the few sticks i tried memtest on was stable ~ -10fsb of that superpi.

[cjoe]

No not stable but the few sticks i tried memtest on was stable ~ -10fsb of that superpi.

Okay. That sounds more reasonable. How long did you test for? Memtest frequently runs clean for upto 10 passes and then generates errors.

Also, you're not encountering DC mode and 1T issues with you're NF3 board. Two single sticks doing 245FSB reliably probably won't do 245FSB in DC and 1T with the same voltage and same tight timings. I have 4 sticks of Mushkin Blue CH5 that will do > 245FSB with tight timings and > 253FSB with slightly looser timings. However, if I take the best two sticks, I can only achieve 235FSB with tight timings + 3.4V or 250FSB with looser timings + 3.6V.

You may have gotten a great batch of memory. :toast:

Maybe both my CPUs have weak memory controllers. Maybe I have two crappy power supplies and maybe my motherboard is not so reliable. Maybe, like you said "user error". (I could be doing something wrong). Finally, I may have crappy luck. :confused: Ultimately, you get what you pay for.

Fortunately, my GSkills do great with my 3000+ Winnie; otherwise, I would be seriously depressed. I should never have purchased those 3GBs of cheap memory because the odds were against them achieving > 265FSB. Any speed less than 260FSB is not significant. I should have purchased the OCZ VX which would have guaranteed ~ 265FSB. Its cheaper than the price of 3GBs of value memories.

Cjoe

[Ubermann]

If you get errors after 10 pass it is most likely heat problem i think.

[cjoe]

If you get errors after 10 pass it is most likely heat problem i think.

I leave the case door off during burn-in and have a 90mm fan blowing directly on the memories. So, I don't think its a heating issue. Its not consistent. I notice that memtest will run clean for a long time with no errors. Then a few errors will crop up and it will be clean again for awhile. Then a couple of errors will pop up again. I've seen this happen on several of my machines as well as others.

I am looking at two different machines right now: DFI NF4 - 43 Passes with no errors and DFI NF2 - 21 Passes with 2 errors during pass #5. Its clean upto pass #5 and clean after pass #5. Its the normal random glitch as the memories get stressed.

My general testing methodolgy is to run a minimum of 10-20 clean passes with memtest before increasing the FSB. After the memory test clean, I usually verify by booting into windows and running OCCT and S&M. If both complete successfully, then I'm golden at that FSB.

I know exactly what I posted, and it was the truth. I posted my results which were good, just because your result werent as good dont meen its my fault. It varies from person to person. If you read this hole thrad you will see that others got even better results them me. What exactly did you buy? Did you get the speed premiums or the tmII400's. Why dont you post your specs and maybe we can help you out. I would much rather have a calm Chester here then an agro Chester. But really if you do want help your coming at it the wrong way.

Sigh.

I've abused 6 different TMSP sticks.
Every single one of them did 2-2-2-x 250MHz +-2 3.3v on DFI nForce2. On current DFI nF4 Ultra-D they do more than 262MHz 2-2-2-6-7-14... 3.5V
My proc craps out before they do.

Tell me that's just plain luck.

[Gray Mole]

Yup...

I know loads of ppl now using this ram, in both flavors, and some are havin' great success, while others got duds...

It is ALWAYS a crapshoot, but that's what makes it interesting...

I say Minty's review on Komplett, but I didn't go telling him off when it didn't perform, nor did I give Komplett an earache, just RMA if they're really bad, or keep running 'em til they loosen up if they have some promise...

I've got a single stick of old skool BH5 that wouldn't do anything over 220mhz and that was at cas2.5, so I ended up putting it into a friend's rig cos he doesn't clock, and in a few months I'll go 'nik 'em back and maybe they'll respond a little better...

You can't shoot the reviewer cos you got a mediocre set...it just happens...

Hi all, ive been following this TwinMOS post for a while now and have decided to take the plunge, however I can get the CH-5 and BH-5 for the same price and cant decide between them, so which would you lot recommend for a 939 neo2 plat?

[Minstadave]

Have you got a DDR booster?

I'd go for the CH-5 I reckon, my BH-5 needs to many volts for decent results, the CH-5 shouldn't need as much.

[AFRS]

im going to get a booster with my order (although not from the same place) and thanks for sugesting the CH-5 i was slightly leaning that way anyway.
oh and Minstadave i thought you were taking a break from memory forums :stick:

Nice work. But I only manage to push my TwinMos SP to 250Mhz (stable) @ 3.5v (2-2-2-2). Prime95 stable for hours. But when I tweak to 255Mhz @3.5v (2-2-2-2), there was a few errors when running memtest86 v 1.51. But it would failed Prime 95 in within 1 minute. (ya. 1 MINUTE only). Now, I am doing burn-in by running test 5# (memtest86). Actually, I had burn-in for more than 10 hours and it is still no go. I don't know what is wrong. May I know did you do some burn-in for your RAM to reach 265MHz. I did pump the vdimm from 3.6v to 4v on my DFI NF4, but giving more voltage would give me more errors in memtest86.

ofcourse RAM can die, but you minimize chances with good cooling.
I would stick to 245Mhz for 24/7 and 250 for benches 3.75 is a lot of Vdimm for 24/7.

I am trying as many timing as possible. If possible I also want to run in 1-1-1-1 or 0-0-0-0 ( I know that's imposible) Now I am running at 2-2-2-6 @ 3.6v. I think my TwinMos SP like high voltage. Last 2 days ago I was running 2-2-2-2 @ 3.5V but it would fail Prime 95 within 1 minute. Now, at 3.6v I managed to run Prime 95 within 9 minutes or more. My goal is to run at 260MHz (DDR 520) at 2-2-2-2 @ whatever voltage. Now I am burn-in my ram at DDR 510 at 3.6v using memtest86 v1.51. One thing I noticed is that when I cool my RAM using 90mm fan over them, there is less errors in memtest (DDR510). If i removed the fan, there is ton of errors. So, heat is the one hinder my RAM in my case. Hopefuly I can get my blow hole done on my case and put a 120mm fan and blow directly to my RAM. (short of money now, has to wait for another pay cheque). My wife also told me that there will be PC Fair in Singapore mid of May 2005. Hopefuly I can get some cheap and decent overclocking RAM

So decided to change to 2-2-2-6. (it still give me errors, but not as many as on 2-2-2-2). One more thing is that I would like to learn from you guys on how to post a screen shot in the forum. I got digital camera and any cable that connected to PC but I do not know how to submit the screen shot. Can I save my screen shot on a floppy and then attach the screen shot via the floppy in this forum. Really need help. For your info, I am using different computer to communicate in this forum.

I got the CH-5 from a friend that had them in an old rig, traded him my Geil pc4000 for the CH-5's, but now I am running only one CH-5 512 and it sucks.

The 1 gig of Geil sucked worse though, BSOD no matter what settings!

2*512Mo of twinmos sp pc3500 on modded Epox 9nda3+

Just ordered 4x512mb of these, hope I get results like yours :toast: My last 2 topped out at 250 with 3.5V

[piotres]

Hello

Do that value PC3200 Twinmoses on 1A4T,AA4T are usually as good as Speedpremiums PC3200-3500 ??

Do you have in yours contries value on CH/BH-5 , too ???

Because in Poland there are a lot of normal value 3200 sticks 256 MB and 512 MB on 1A4T or AA4T ... I can even say that now, in Poland we have more Value on UTT/BH-5 than SPremiums :lol:

Some people in Poland clock that value to something about 250-255/2-2-2/3.4V on Nf4 (best 250/3.1V/DFI Nf4 on 1x512 MB AA4T), but I don't know that all of that value AA4T/1A4T are good ?!

Please post yours O/C results on Value PC3200 Twinmoses, specially if you have Nf2 board, but not only - please write also results on Nf 3/4 boards !

Thanks a lot .
Best Regards,
Peter

I have TwinMOS A4AT ($95 @ newegg). On my DFI LP UT 250 i could do 240mhz @ 2-2-2-5 on 3.2v. I have a neo2 now so i cant really run them to potential (even 3.2v isn't really potential), but I'm getting an ultra-d within the next few weeks so I'll be pushing 3.6+ :D

Hi,

which chip u guys are getting when buying memory* from newegg?

*256MB DDR400 not speed premium (is there any chance to get BH5 ICs 1A4T? Is there any chance to get PSC AADT?)

$95 at newegg? Did you get the TMII 1 gig kit rather than the Speed Premiums? If so, sounds like you either got lucky to get Winbond chips or TwinMOS is putting Winbond back on these as well.

[Mr. Tinker]

Do you guys think I should sell my Kingston KHX3200ULK2/1G (1gig TCCD) and buy some 2x512 TMSP400 and a booster for my Intel rig?

I bought TMII and did not ship with winbond. I called newegg and they don't have this value with windond for ages.

And guess what. They have been cleaning the reviews they don't want so people buy them in mistake. They did to my review. I will never buy again from newegg

Has anyone tried running tRFC 12 with CH-UTT? Or atleast <15?
Just noticed my Speed Premiums run fine 200MHz 2-2-2-6-7-12 @ 3.1V.
(I didn't try any other voltages or HTT)

How much does tRFC impact to B/W? Memtest86+ 1.55's B/W didn't care about any given value.

Well, after fighting the cold boot issue the last few days, one of my twinmoss sticks is bad. I've been researching other peoples results/problems with these sticks, plus my own, and I think that the life of them is pretty short. I bought them on Feb 20th from newwegg and they have been great sticks, but I think running 3.4-3.5 volts for 24/7 is not a good idea. New memory every three months is not for me. I'm curious how long others have been able to run these with high voltage. Maybe I should start a new thread on that topic.

[celemine1Gig]

Well, that's the reason why those voltages are not guaranteed by Twinmos. ;)
What most people don't get is that those RAMs need really good cooling at voltages of >~3.0V. And for 3.2V and more, a fan only won't cut it IMHO. The heat that is produced by the chips gets too big and the chip-surface is not big enough to dissipate it fast enough. That's exactly why I would never use more than 3.2V on sticks without proper heatsinks on (and a fan blowing over them).
But sometimes even the heatsinks and fan won't help, as there will always be some modules that can't stand the volts, regardless of cooling (perhaps those sticks even would die at stock speed and volts; it'd just take longer I suppose). But hey, that's the risk of buying stuff that isn't guaranteed to run at the frequencies or voltages that you intend to run it at. As always, NO RISK NO FUN. :)
So I'd say, if you really want to run voltages in excess of 3.2V for a longer period without frying your RAM, get a big and powerful fan (not a quiet and small one) and get some heatsinks for let's say 6$ per stick. This way, you play it safe. If it dies although you did the best to aviod that, you know it really was bad RAM. But if you don't do that, you'll never know if it was bad RAM, or if you literally fried it. ;)

[[XC] 4X4N]

I have two 80mm fans blowing over the ram. I don't have a way to check the actual temp of the ram, but many times I would check with my fingers, and I never found them to be overly hot. I understand the risk in overclocking, just sharing my experience with others who are thinking about this ram.

[uwackme]

Been working on SanDiego....

the 245Mhz AA4T TMII sticks I set aside for my brother are doing 260Mhz in memtest, and 250Mhz rock solid in Windows/3D/Prime. Im testing 250Mz x10 at the moment. These sticks peaked at 245Mhz 3D/240Mhz prime stable on my NForce2 system. Using 3.4Vdimm at the moment.

[vapb400]

Wow. I have spent several hours trying to get my sticks to pass memtest at any speed/voltage, then finally I decided to pull them out and test each one individually, only then did I notice that I have one UTT and one BH-5. Both were ordered from newegg on the same day. I could boot into windows at 250 with both sticks installed, but it wasnt pi stable or 3dmark stable, although my applications ran fine. So I decided to pull the UTT and am testing the BH-5@250 2-2-2-5 w/ 3.4v memtest stable, havn't tried higher yet, I wanna play some games. I'll trade sticks after I'm done, see whats up.

So what do you guys think I should do? I want to run dual channel, so I would probably want to RMA the UTT stick, should I go through TwinMos or Newegg?

[CarbineBoy]

I'm maxing out at 250mhz, 2,2,2,7 @3.2 volts any ideas to increase? I'd like to get to 260 to 265. Whats the max safe 24/7 volts?

[xenolith]

Well, that's the reason why those voltages are not guaranteed by Twinmos. ;)

That's exactly why I would never use more than 3.2V on sticks without proper heatsinks on (and a fan blowing over them).
If this were true than i seriously doubt Mushkin would spec their Redline @ 3.5v (w/fan) or OCZ would spec their VX @ 3.3v (w/ no mention of a fan).

But sometimes even the heatsinks and fan won't help, as there will always be some modules that can't stand the volts, regardless of cooling (perhaps those sticks even would die at stock speed and volts; it'd just take longer I suppose). But hey, that's the risk of buying stuff that isn't guaranteed to run at the frequencies or voltages that you intend to run it at. As always, NO RISK NO FUN. :)

Ramsinks @ 3.2v~3.4v are overkill since i believe these Winbond chips are rated up to 3.6 volts. :2cents:

WHY my Twinmos UTT AA4T can not do 2-2-2-5 ? Only possible in 3.0 v ???? :(

[Lord_RTKK]

WHY my Twinmos UTT AA4T can not do 2-2-2-5 ? Only possible in 3.0 v ???? :(
Simply: because they are untested CH-5, and they only do 2-2-2-5 over 3.1v (apart of magical sticks, of course...)
If you need 2-2-2-5 at a low voltage you should go for BH-5 die or TCCD (always at low FSB´s..., if you need 2-2-2-5 at higher FSB´s, then BH-5 or CH-5 will work right, but with 3.4v+... :D )

[icyroy05]

Just got my 512mb stick of speed premium from newegg. It reads AA4T.
On the chips themselves they read this:
TwinMOS

TMD7608F8E44D
and on the PCB they have B6U815. I was just curious if the PCB is brainpower or not. I think the chips are UTT because they have the two dots and all that stuff that UTT has.

You have the same stuff as me... TwinMOS SP with 44D chips... :toast:
Look at my signature :D :D you should be able to get 260+ with some volts on your sticks :D :toast:

[icyroy05]

Thats pretty cool considering I just upgraded from a pentium 1 200mhz computer. The memory alone can clock higher than my old machine.

At least this looks more promising than the mushkin blues I RMA'ed because they couldn't run at stock speeds no matter what I did. These do so far. It was a hassle getting the right memory but it looks like good things come to those who wait, or have a lot of money. I don't have a lot of money but I do have patience which is amazing for a 18 year old.

But when I swich on my DFI, I forget those things... :D :D :D
Tell us how those UTT perform... ;);)

[longsiew]

First of all, I don't know I am posting in a right thread. I have some critical situation here. For the past 2 months, I could do 250Mhz without problem (256mb x 2 @ 3.5vdimm @2-2-2-2). Stable at all time. But, last night, I encountered a lot of problems.
I am running dual channel on orange slot on my DFI NF4 -ultra.

First: My comp keep on beep.........when I unplug the power core and plug it back. (Overclock) My comp can't even boot (Blank screen)It sounds like RAM problem.

Second: When running everyting on default (no overclock) my comp works find. Can run benchmark and everything. Even when I unplug the power core and plug it back again.

In tackleling the first situation: I took out a RAM stick (RAM A)from the orange slot (near to CPU) and leave one stick (RAM B) in another orange slot. (it can boot into windows and do benchmarking and running applications). Thus, RAM B is ok. Next I took out RAM B and replaced it with RAM A and the comp failed to boot and keep on beep....beep...beep........ My conclution was RAM A is faulty. But my conclution was contradicted with the second situation as above.

At first, I though it was BIOS issues, thus, I reflash my Bios to 310 (Official) and the same result occured. So, I reflashed it back to Bios 331-1 (Oscar Wu modded bios) So, my problems seems something related to pluging and unpluging the power core for overcloking.

I don't think my PSU is an issue here because when I tweak all the necessary setting in the CMOS to overclock my comp, I saved it and the comp restart and manage to load into windows. Under this circumstances, I managed to run some benchmarks but sometimes the comp would hang. Furthermore, if my PSU is the issues I don't think my casing fans (90mm, 80mm x 4) can work. All the casing fans are rated 12v to operate.

My doubts are:

1) Is one of my TwinMos SP is dying?
2) My Bios causing problem (But I am using 310(official) before I flashed it to 331-1)?
3) My DFI Board ?
4) My PSU ?
5) My RAM Slot ?
6) My CPU ?

Really appreciate for all the helps and I really need the assistance from all the expert here.

[Funny_S]

bought 2 sticks speed premium pc3500 (bh-5) of 512Mb the other day.
I'm still working with one stick which goes up to 258Mhz 2-2-2-5 3.5V, raising it to 3.6V or higher doesn't have any good effects.
The other stick couldn't even reach 200Mhz 2-2-2-5 at any voltage. If I used 2-3-2-5 I could go up to 250Mhz with 3.5V but wasn't good enough so RMA'd the stick.
Allready ordered some OCZ value sticks, 2 new SP PC3500 and not to forget the amazing Mushkin XP4000 Redline. I will keep the ones who hit 265 or higher, the other ones are for ebay :p:

:yepp: B6U815 is Brainpower PCB. Mushkin Blues has the same board.
But don't get too excited, they don't do any good on Blues either.
And if I remember correct, Alonso mentioned TwinMos experimented with Brainpower. No gain for UTTs.

@longsiew: i'd say that is due to run a long time using 5V line to the memory, with the consecuent mosfet stress... :stick:

[uwackme]

Just to see what 4x 512M of the cheapo UTT/VX Twinmos can do....

CPUZ validation... ID# 18496, look it up.

Working like a charm, though 2T and no BankInterleave is required so far to make 4 sticks play together.... 3.4Vdimm.

I've hit 230 memtest and prime stable with my winchester and 4x512mb of UTT-BH5 2-2-2-5 2T 3.2V with Bank Interleave on, so you should be able to squeeze a little more out of it.

TQ for the reply. But can you enlighten me on this. Does this mean my mosfet is faulty or my RAM is faulty? So how to remedy the mosfet problem. Last night I could run my comp and benchmarks at 260MHz with ONLY a stick of RAM. Of course, the performance is affected by this. My sisoft is at around 36** and it is half compared to dual channel which was around 71**.

Sorry, but ^don.k's^ affirmation is not true, because my new DFI i have got RMAéd (because the first one did the same things as yours) is still doing same strange things, and I havent got changed the vdimm jumper to 4v yet, so this is not the cause of the problem...
I have also changed my CPU (thinking about faulty mem controller) and the problem is still here.
I have tried different PSU´s, because my main PSU is 20pin, and DFI says that the 4v for the vdimm shoudnt work with this type of PSU´s (but it works perfectly... :D ) and have tried with an OCZ 520 24pin, a CoolerMaster Real Power 450 24pin and it does the same things...
I have tried other ram, and the problem hasnt gone.
Resumming, I am thinking about incompatibilties between DFI NF4 and UTT...
When my mobo starts to give me the problem, I swap the modules in the slots, and then it boots fine...
Is not a BIOS problem, because my new DFI RMA´ed is still with the BIOS from factory, and it does the same weird things...
I think that we will have to live with this problem, or change our DFI by a MSI Neo4 + DDR Booster... :nono: :D :D
Hope that all of my tries to find the cause of problem could help some1... ;)
Tell me any idea that you have about this problem... :P
Bye!

[uwackme]

MDave, you were right, Im re-testing with bank-interleave ON. Working fine.

Also dropping Vcore as low as I can go, so far down from 1.64Vcore to 1.52Vcore and still 3D/Prime stable. 32M SuperPi is 26m54sec with 2T on 2Gigs of ram, 250Mhz x11 1:1. Searching for the sweet spot of lowest stable Vcore at these tight settings.

The Sandiego is truly amazing, and it's mind blinwing how well these $208 2Gigs of ram are working :banana:

Good to hear from you. Come to think of it, I think you are right. Because I tried a lot of Bios including 310(official), 316, 331-1,331-2,331-3 and 509-2 and I can only stick to ONE stick. Anyway, I can boot and load into windows with two sticks of TMSP without overclocking. (This is the most suffering part). Now I can only overclock my graphic card. BUT, I won't give up and I want to bring back my previous DFI that could do 453MHz(HTT). Hopefully, my DFI get a lot of rest now (because I did not oc) and come back to life after a week. For the time being, I have to live with it.

[vozbidder]

Simply: because they are untested CH-5, and they only do 2-2-2-5 over 3.1v (apart of magical sticks, of course...)
If you need 2-2-2-5 at a low voltage you should go for BH-5 die or TCCD (always at low FSB´s..., if you need 2-2-2-5 at higher FSB´s, then BH-5 or CH-5 will work right, but with 3.4v+... :D )



And i must buy another RAM ? :( This one can reach 250 2-3-2-2@1T with only 3.2V , not too bad ??

200fsb 2.85v

210 fsb 2.85v

215fsb 2.95v

220 fsb 3.0v

225fsb 3.0v

230fsb 3.1v

235fsb 3.15v

240fsb 3.3v but with some errors and higher volts will not remove them.

if i lower the timings to 2.5-2-2-5 it gives no errors.

at 245fsb 2.5-2-2-5 i get some errors

at 245fsb 2.5-4-4-8 about 100 erros each pass

at 250fsb 2.5-4-4-8 i get about 2000 errors each pas of test no 5 at 3.5v and higher.

when testing at 240fsb 2-2-2-5 3.3v if i lower the the ddr volts i get errors like

fffdffff fffdff80 but if i then increase the ddr volts it changes to 00100000 00000000 and if i increase the ddr volts a little higher these erros increase too.

also when idle the ddr volts increase to 3.45. then when i start testing they drop to 3.0v and then by then end of a test #5 run stabalise at 3.3v.

is this normal for the ddr booster ?

is there any reason the errors change at higher fsb when i increase the volts i thought it could be a cooling problem but after adding a 12cm fan and 8cm fan i still get them.

[uwackme]

I am soooo confused.

I have 4 sticks TMII Twinmos UTT, and 4 sticks of Twinmos 3200 SP also supposed to be UTT but 44D chips.... AA4T etc.

The SP's wont run for :banana::banana::banana::banana: in the A64 system, but the ordinary TMII's run 260Mhz @tight flawlessly, 2xsticks 1T 4xsticks 2T.

WEIRD!!!!

But these SP's run great in NForce2, fast pair does 250Mhz slow pr does 245Mhz without any problems (though one pr has some high voltage issues over 3.3V, freeze-up/lock-up).

BH5 Kingston acts the same, wondering if I got SP's that are actually BH5 before the chips were marked, so Im actually trying to get Apples to taste like Oranges?

i ordered 2 twinmos 512 Speed premium from newegg. E44B bh-5. I was hoping for ch-5 since that's what is advertised at twinmos. stupid me to think i was getting what was advertised! TwinMos Ad (http://www.twinmos.com/dram/dram_p_sp_ddr400.htm)


what can i expect to get out of this?

3500 winchester, DFI nf4 SLI, MSI 6800gt

Just got my 512mb stick of speed premium from newegg. It reads AA4T.

I just ordered 2 more sticks this morning so I could try a 4x512 set-up. I already have two AA4T (CH) that do 250 at 3.3 rock steady. If the new ones don't match I guess I'm screwed.

I found the twinmos sp 3500 is running to warm from high volts and speed.

If i run at 200fsb 3.4v no problem as i increase the fsb when i get to 235 fsb it starts to get warm and the 01000000 00000000 erros start. if i then drop the volts i can make the errors go away at 3.1v
I had 1 80mm fan on the ddr booster and a 120mm fan over the ram but it made no differance.
Heat spreaders allowed me to run at 240 but for a short time but it didnt take long for the errors to start and i couldnt lower the volts any more.

I tested some corsair xms3500 bh5 (2x256) and they ran perfect upto 260fsb no problem.

One thing i did find was the time it took to run a single memtest #5
at 225 fsb 2.5-2-2-5 with the xms 3500 35 seconds but with the speed premium 86 seconds with no errors.

[slunge]

i had my 2x sp3500 replaced today with 2x512 sp3200 (utt's) and im no longer getting the troubles i had with my 3500's

i have to say though, on a nf7-s running 225 with 3.25 volts they are gettings amazingly warm, i have a 92mm fan attached to the top via that band method and i did attach some heatspreaders but took them off for testing, am tempted to put them back on again but have heard they dont help...

still, fairly stable at the moment 225 2-2-2-5 was hoping for a little less heat and tiny bit more speed but still.. cant complain :)

This is the email i sent and the answer i recieved from twinmos about the bh-5 on the speed premium 3200's.

Hi i ordered 2 x 512 TwinMos Speed Premium pc3200 from newegg. i ordered these because at your website (click here) (http://www.twinmos.com/dram/dram_p_sp_ddr400.htm) this ram is listed as having the winbond ch-5 chips. these do not have the winbond ch-5 chips, they are bh-5 on the modules i recieved. The only reason i ordered these was because TwinMos advertised as CH-5. Are there any CH-5 available? and if so may i RMA them for exchange? thank you!
Lynn H.

Dear Lynn,

Usually the BH-5 chips is more expensive than the CH-5 chips because of
better performance.

As we don't have the CH-5 chips available now, so my suggestion is to
keep the BH-5 chips.

Regards,
Alice


Do u agree with alice that bh-5 is better than ch-5?

... if every man of this forum tells u to keep them, u wont listen, but u need a women to tell it to you ;). Keep them man.

[el_]

I got BH5 too but I am keeping them if they don't error out at 200 in memtest! You will have to pry the bh5 out of my cold dead hands.

argh u guys are killing me with this ch5 bh5.This mem worst i ever bought,but for the money hey ok.I ate this stuff and its bh5.My freind proved it to me as we put them together.IN my opinion, wich is whatever.spend like 10 more euros or 15$ more and get some mem that runs.This is the second and last time i buy this mem.Sry to disapoint u guys getting low timingns and high fsb from this stuff.I have had no luk with this stuff

I'm screwed. Opened my package yesterday and saw I had received 1A4T BH-5. So much for trying 4x512 this weekend. So I figure I just head back to the NewEgg site and order up another pair ... OH FOR F**Ks sake! They're sold out. No joy. This 2gig memory project is turning into a pain in my butt, as well as my wallet.

[nugzo]

I'll trade u my 2 bh-5 i just recieved for your 2 ch-5 :)

Oh well. :rolleyes:
1AA4t <---------::{ GOD ihate u ;-)
1A4T is the BH-UTT. (...or was that a misstype?)

[slunge]

given the choice, and ive had both now (CH5/BH5 UTT) i would stick with the ch5 i have now every time :)

[gundamit]

Well I tried putting in both the TMSP CH and the BH UTT and it actually seems to to be showing a bit of promise. Set everything to auto except
CAS = 2
DRAM Bank Interleave = Enabled
DRAM Drive Strength = Level 8
DRAM Data Drive Strength = Level 4
Max Async Latency = 8ns
Read Preamble Time = 6ns
R/W Queue Bypass = 16x
Bypass Max = 7x
32 byte Granularity = Disable(8burst)

I guess I will be playing with it over the weekend. I might have to go with this instead of a 2x1024 set-up. I'm liking the 3v but just like the Geil 2x1024 pair I tried I can't use a divider lower than 3:4.

I must be lucky, SP BH-5 3200 2 x 512 @ 245 3.25v. They will go higher, just cpu memory controller won't.

With alittle more testing, im able to do 223 2-2-2-5 1T or 243 2-2-2-5 2T on my nf7-s with 3.25 volts (seems to drop to about 3.19 under complete load with Vio=Vdimm mod).

I must be lucky, SP BH-5 3200 2 x 512 @ 245 3.25v. They will go higher, just cpu memory controller won't.Mine top out @ 265 @ 3.45v :)
Running @ 260 24/7 is no problem, a 12cm Enermax fan pointed at them @ 2 inch distance, 1500rpm... very quiet but still good airflow :)

Best bang for the buck :D

v
Wont the vencie let u do 1t with 4 dimms? i noticed your poor old winnie will only let u do 2t.

[gundamit]

I must be lucky, SP BH-5 3200 2 x 512 @ 245 3.25v. They will go higher, just cpu memory controller won't. Drop the multi down on the CPU and see if you can crack 250@3.3v.

Mine top out @ 265 @ 3.45v Right up there with the premium OCZ and Mushkin CH UTT. Could you share your bios timing?

Wont the vencie let u do 1t with 4 dimms? Before they came out, it was hoped the E revisions CPUs (San Diego and Venice) would do just that. Although they won't kick down to DDR333 speed when 4 dimms are used like the Winnies, I believe they still run 2T with four sticks. Memory controllers are improved on them, allowing for higher OC's overall, but you lose a bit of bandwidth clock for clock because of looser latencies on the new memory controller.

Speaking of codes, I've copied from OC Forums some info pulled from Kingston Value Ram. The first set of numbers are off a 512MB stick which was purchased from Fry's and tested on the same P4 rig as the OCZ. Hit the same 255 at 2-2-2-6 with 3.6v and the second set of numbers was from a retail box at CC of 2x256 which I spotted but left at the store because of the high asking price. I was just interested in seeing if there were any locally and what info was on them so I could pass it along. The first KVR stick is pictured at OCF and has the name coding pattern as I've described below. Here is a link to that thread, see post #73 if you are interested in the picture of the KVR. It is not a great picture, but you can see the peculiar layout of the chip's coding.

Copy of my post at OCF (2x256 set):
******************************************

I found a set of 2x256 at a local Circuit City which match the pictures taken by Diablo except for some minor differences. I did not get them, again, because they were priced at $150 after sales tax for 2x256.

Note one item of interest. Usually the Kingston label is across the top and then the numbers below. These chips have the first set of numbers to the right of the Kingston label, so both the name "Kingston" and the first set of numbers are on the top. In many cases, the date is on the second line, and then the chip coding is on the third line. These chips have the coding on the left side of the 2nd row, which is actually across the bottom, then what appears to be the date, plus more coding to the right. All of the second group of numbers are across the bottom row of the chip.

The set I found was coded like this.

First row - label and numbers: KINGSTON 401137.05

then blank space with the circular Winbond "dimples" visible,

followed by the chip code & date: D3208DL5T-5 0416PT01

Hey i just skimmed through this thread and found that i have the same memory. TIme for some hardcore testing!

[Sila]

Hey i have 2 x 512 BH-5 KHX3000, they do 250 2-2-2-5 @ 3,2

Is there any point in changing then to Twister Speed premium??

Is there any gain? (Damn hate that word "GAIN")

[fatfreepork]

depends what you are looking for. Twister is Tccd so you will be getting higher Htt but not the tight timings.

[Sila]

I´m looking for BH-5 on brainpower print, but is there any gain? Would i be able to run 260-270 2-2-2-5 @ 3,2?

What brand is bh-5 and Brain power?

[esdee]

depends what you are looking for. Twister is Tccd so you will be getting higher Htt but not the tight timings.

latest twinmos twister have BH5 ... it's written on the HSP too ;)

I´ve seen that but how well do they OC? There is no point in selling my khx if they are crap OC`ers

I can get 170 euro for my 2x512khx, and get some speed premium for about ??? what, a 120-140euro??

[easypanic]

Depends where y a from, in .de they can be found for ~150 euro's.

I´ve found then in norway to 116 euro! (2x512)
