OCZ VX, Best Memory made since BH5!!

You've got PM.

hey's guy's I just tried out the 2/09 bios on the DFI NF4, and noticed at 265 my VX was giving off a ton of errors which it didn't with the 2/25. Basically I noticed that after the Level4 option in the bios, some of the settings were changed from auto in the 2/25 to different values. Now being the idiot I didn't try changing one at a time to isolate what setting it was, but by changing all to auto and the second to last to 07x I was able to run 265 again with no errors.

2-2-8-2-7-16-2-2-2-2-auto-auto-enabled-auto-0-auto-level4-auto-auto-auto-auto-auto-07x-auto

Now I am sure these are not very great optimised settings as I only get 3.8K unbuff at 265 but it does atleast let me get an OC and able to tweak a bit. Just thought you all might want to try it out.

Have you tryed changeing the 16 to a 17 and see if it helps get you higher clocks?

[LikwidKool]

Actually I really haven't tried changing much. I just really got this board set up a day or so ago. Half of those settings I got off of a post by Radelon. Now on my K8N Neo2, 261 was tops. So in all I am getting a little higher clock off the bat.

I am running to work right now though, but I will try tonight to see what happens. I am also going to try and isolate what settings were giving the errors.

[AMDfan]

sure i'd believe you. my 3200plat rev2 did 285 2.5-3-36 @ 2.85v. it's not a stretch of the imagination that another person could do it at 2.7. that is of course assuming your psu rails are all at stock.
Thanks alot for believed me for that, but the problem is, I don't believed it myself :( , like you said you did 285mhz at 2.5-3-3-6 with 2.85v that's cool, I can swallow it, but, 285 2.5-3-3-6 with only 2.7v :shakes: I understanded that TCCD chips don't need much voltage , but still hard to believed :exclamati

[pumbertot]

this is a n00b question i suppose but when you guys say to run at test 5 on memtest why is this?isnt test 8 more intensive on the mem?

5 uses less ram so the ram that is being utilized will heat up more than using test 8, possibly. But test 8 runs longer (but through more ram, so..).

Nobody has looked into which is better really.. :D

I've heard to run test 5 looping first for your burn in. Then find your max where it doesn't show any errors and then run that same FSB with test 8. Usually it will show some errors until your FSB comes down but not much maybe 1 to 3 FSB. Just my 2 cents

[DildePer]

If you are running, say - 3,3V. Wouldn't you need some cooling besides the OCZ heatspreaders?

vx dont really get warm btu I always had a silenx 80mm over them via a zalman bracket, more to keep the booster cool than anything.

Tony from OCZ (thanks to Ryanpgroovy) has kindly offered for me to send the dead VX to him and he will have immediate replacement shipped from US.
Lucky for me he is due to meet his US counterparts or I would have had to mail them to US.

cheers OCZ guys. :toast:

Cheers, and thanks for bringing me the good news :D

Well, not all is pink color.

I tried a kit of 1 GB (OCZ PC3200 VX) and was something disappointed. They were unstable at 3.1v 200 MHz 2-2-2-8, but at 3.2v they were stable up to 240 MHz wirh 2-2-2-5 and without preburning.

Now my problem, I don't know why but my OCZ Booster was unstable with these memories, even if I tried 3.4v the voltage sometimes fell to 3.0v causing in that moment my Windows to crash and to restart, with a pair of BH-5 my Booster was completely stable and never had a problem, geez.

So I had a chance to sell both, my VX and my Booster to different people, phew, now I'm waiting for my GSkill LA, let's hope I'd be happy. :)

sounds strange though hasnt there been this issue raised b4 with some enermax psus and boosters?

[Gauss]

I wish I could know. I'm using a PC Power & Cooling Turbo-cool 510 Deluxe and the MSI K8N Neo2 Platinum. The Booster was fine with BH-5, but with the VX no luck.

[DBZ_GOD]

Hey, i am just wondering if people could help me out with my OCZ Gold VX timmings. i got the following hardware:
DFI NF4 Ultra-D motherboard
AMD Athlon 64 3200+ Socket 939 with XP-120 and fastest Panaflo
OCZ powerstream 520watt psu
OCZ 2x512MB PC3200 Gold VX
ATi X850XT-PE PCI-Express
Raptor HD 74GB

The best Stable overclock i have gotton is 260x10 at 1.6vcore 3.5vDimm at 2-2-2-8 timmings but i know that the Gold VX can do better, any suggestions or exact settings to use on my Gold VX with the DFI NF4 motherboard?, Thank you.

Edit: I am using the stock BIOS 1/25, out of the beta ones is their a really good one to use?

[Revv23]

Burn in may be your best bet, 260 isnt that bad, just lower then average.

[DBZ_GOD]

whats the best way to burn in ram?

[andyOCZ]

whats the best way to burn in ram?

Hi, you can run at 200mhz, aith 2-2-2 timings using 3.2v for about 48 hours. 24 hours minimum. Run memtest and loop test 5. Memtest can be turned on in your BIOS.

This procedure seems too help when you crank up the volts and speeds later.

I will be starting a thread tomorrow with some suggested VX timings here on XS. Check it out then.

[DBZ_GOD]

okay, but as for the memtest, i looked all over in my BIOS and found nothing related to turning on memtest or memtest itself at all!?, my guess it is under some other name in the BIOS other then memtest but i dunno what its then called.

[LikwidKool]

it is in the bios genie section. Just keep scrolling down under the voltage options and you will see it.

As far as your previos post, 260 is pretty good. Mine do 265 but only after burn in. I have a post around here somewhere with some timings to use, but I haven't investigated every option in the dfi bios. I have my pc3700 gold rev 3's in right now so I can't even check a64 tweaker.

**EDIT** Here's the link to my post. Just something to try.

I looked below the voltages, and all thats there is the 2 lan cards, SATA ports and firewire options no memtest at all, i am on the stock 1/25 BIOS so i guess i gotta flash to 1 of the betas to get memtest built into the BIOS?

The latest memtest version is included in the latest beta 0218 bios for the DFI LP NF4's.

Just got my RMA replacement for the VX and im a little disappointed to say the least. the pair RMAed did 250 2-2-2 at 3.5V no sweat.
put these new ones in and was disappointed that they wouldnt do a single loop of test 5 at 3.2V 2-2-2. in fact had to up all the way to 3.5V to get it to pass at 200MHz. :(

tried at 240 3.5V-3.7V and errors at first loop. so ive dropped back to 230MHz 3.5V and they passed. Im hoping if I leave them for 48 hours looping then they will improve but I dont think they will really get that much beter or am I wrong?anyone get a great increase after burning in?

btw im on a neo2 s939 with 1.36b BIOS. the most annoying thing is my CPU will do 2.7GHz but since the dividers dont run on this mobo with VX I could be stuck at say 2.35-2.4GHz. :(

arent these tested to at least 240 2-2-2?

[Chr0n1c]

wow and ppl said I was picky about mine maxing out @ 238Mhz, you RMA'd a set that did 250?

They are rated @ 240 2228 but not test iirc.

I tryed to find a optimal timing for the DFi nF4 and VX mems, is this quit hardcore?

Or what do you have benching/ 24/7 use?

chers

[LikwidKool]

I was using that for 24/7 use. I haven't gotten really tweaked benching timings yet, cause I was spending so much time on my SLI setup. Come to find out one card was borked.

Basically all the non auto setting are pretty good. The 2/25 bios also sets some really good timings, and is pretty fast but still alowing max OC.

Please burn the VX in and see what you get. We are testing no different than we have all along.

Are you cooling the modules with a fan? If your last set died it was probably due to heat. Heat will also cause errors.

do you think i should run them at say 230MHz 2-2-2 at 3.5V for 48 hours to burn them in, as they wont run at 200 and 3.2V, needing 3.5V to be stable at even low frequencies.

btw I do wish to point out that OCZ RMA process is second to none and I have nothing but the utmost praise for the customer care you guys provide. Big thumbs up! :toast:

edit:ive always had an 80mm silenx blowing on these via a zalman bracket and they are barely warm to touch.

[DBZ_GOD]

Hey guys, when burning in the ram does i half to have them doing a test loop of #5 for 24hours stright or do i gotta do like little increments like, looping for 6 hours when at work, and looping for 10 hours when sleeping etc etc?, cuz i use my computer everyday so i can't really just let it sit for 24 to 48 hours stright letting the ram burn in.

[andyOCZ]

The main issue is not slamming it with 3.5v right off the bat. You can certainly run at lower volts and memtest when you are not using it. No problem there.

[DBZ_GOD]

Okay good thats a relief cuz i just don't got the time to do 24 to 48 stright, so thats good, but too bad i didn't know that before, cuz i slammed mine with 3.5v right off the bat, and well there dead lol :lol: so there gonna be RMA'd , but my next pair i will do the memtest looping of 3.2v for 48 hours totaly then go for the overclocks and not hammer it with 3.5v right off the bat.

[sinsinking]

got 2x512 OCZ PC4000 VX

i did burn-in them for ~20H at 200 2-2-2-5 at 3.2V

but they only get stable@250 on 3.5(!!!) V :(

what could i try? which bios works best 4 vx px4000?

[1337mr.hanky]

this is a very handy forum, at least some people who know something about hardware

anyways, im planning on buying ocz vx as well (pc3200)
in combination with dfi nf4 sli-dr 3500+winny and xfx 6800gt

should give me a pretty fast pc
i will build a waterchiller somewhere in the summer break to make it fly, will have more time and money then

hope the memory will do good, but i'm pretty sure cause of all the good feedbacks on the memory "best memory made since bh-5"

Keep burning them in.... I doubt you've maxed them out yet... if they still don't do 250 @ 3.3V after a week or so of burning in, make a post in the OCZ forum about it and the OCZ reps will help you out.

[Th3__W00T_GuY__]

but shipping in the us is VERY expensive from europe (austria..) :(:(

how should i burn them in?

2-2-2-10-1T@200@3.3V OR 2-2-2-10-2T@250@3.5 OR another possibility?

i should burn them in >80h ????

[Torin]

OCZ recommends 2-2-2 @ 3.2V for 48 hours, then just keep pushing it up until you start getting errors, then let it run test #5 until the errors are gone. Eventually when you hit 3.5-3.6V and are still getting the same amount of errors after hours of test #5, you can assume you've hit your limit... then back it down until you get no more errors and that should be your max.

[Th3__W00T_GuY__]

so, i did memtest 24h now, but i will let run memtest86+ 1.51 for another 24 or even more h!!! but my bosster is :banana::banana::banana::banana:ed up i guess.... suddenly it showed 3.0Vdimm! and then i got 450000 errors... so i had to adjust it to 3.2V again... should i continu with this errors?? (they did just appear once!)

[pumbertot]

yeah but how do i burn mine in as they wont do 200MHz at 2-2-2 3.2V. anything under 3.5V gives errors.bah!

ops .. wrong post

[Terry]

i didnt exactly read every post of this thread but has anyone ran them through 50+ passes of memtest @ [Edit: whoops.... 260-270mhz] 2-2-2 and not got any errors?

BTW, I think I saw my stickers on there said 2-3-3-8...does anyone elses say that? I assume that's the rated speed for defaults, and the volts need to be applied before 2-2-2 is obtainable.

The stickers on the new kit that I received today say 2-3-3-8 PC 3200 Gold Edition VX

I guess that is for 2.6 VDIMM?

[derubermensch1]

From reading over at BE they say the sticker represents the SPD to ensure that they boot safely. Can't remember the actualy post about that tho but it was confirmed by the OCZ reps and they assured everyone they're still rated at 2-2-2-8

heh, I'm kind of having some funky results with that too. "Less is more" :lol:
I burned mine in at 3.2v (2-2-2) for about 24 hours, and then I slowly worked my way up to 250 at 3.4v. Any voltage over about 3.55 I get a ton of errors in memtest (no matter what speed). I guess I'm not cooling them enough for that high of volts...
I'll play with it some more later to try and get it stable at high v, but for now they're looping memtest at 255 (3.4v).

After reading this thread, I dont realy know what to do ?

Everybody advices to run these modules at an DFI board but I'm using the MSI Neo2 Platinum...

Any info ?
They need volts to run tight timings

If you can't put 3.3v-3.4v into the VX memory, it will not work for you. TCCD is best at lower volts.

[BerT]

I have a OCZ DDR Booster
And I already have some tccd (OCZ pc4000 gold rev2) who manages to do 290HTT but i want tighter timings.

Any advice ?

I think that UTT at 260~270mhz with tight timings get way better perfomance than 290mhz loose timings. (u could use a divider and done ;))

[Rabbi_NZ]

1) UTT @ 270 is damn rear... and probably not possible at 3.5vDimm unless you get damn lucky sticks.

2) I am pretty sure OCZ pc4000 gold rev2 are Hynix DT-D5 chips... Hynix for sure but the code may be different

Im not saying 3.5v, thats way to less. All the DFI Owners got 4volts to burn those chips up to the sky ;).

What is the safe 24/7 v for the vx ?

[pumbertot]

What is the safe 24/7 v for the vx ?


if you have a fan blowing over them id say up to 3.7V is safe enough for 24/7 use but the best way to decide is by how they clock.

e.g. if you get 265MHz 2-2-2 at 3.5V but only up to 268MHz at 3.7V then better off running at 3.5V.

however if say they wont go above 250MHz at 3.5V but will go to 265MHz at 3.7V then you now which one to go with. ;)

[pumbertot]

[QUOTE=Rabbi_NZ]1) UTT @ 270 is damn rear... and probably not possible at 3.5vDimm unless you get damn lucky sticks.




i disagree having had 2 sets of VX and one of twinmos UTT all doing above 265MHz at 3.5V.

I'v got a xp120 and it stretches over both mems so the cooling problem i think is solved.

[Revv23]

id be careful with 24/7 at 3.7, the max most went on BH chips were 3.6 24/7... but i guess i havent heard of too much dieing anyways...i think anything over 3.4 becomes a risk, but all overclocking is a risk, just a matter if you want to take it.

[Jacke2k]

Thats true but i think the vx has garanti up to 3.5 v

[loc.o]

They are actually rated 3,5v + 5% makes 3,675v

[Der_KHAN]

so, i can rma my vx if it gets errors on 3.5v while 3.3v at the same clocks is stable!?

[loc.o]

I just meant 3,675 is max volt you can feed it without loosing yr warranty.

[FireDragon]

PFFT warrenty...who needs it!!!

Any way this is some GREAT ram..you can get a little more performance out of by using cas 1.5 and not loose any OC...But i love mine better than BH-5 but hell it is CH-5-UTT...some new BH-5-UTT is cooming out here in the near future though...

Dragon

[Revv23]

[Gray Mole]

Just thought I'd post a taste of my VX results...

I'm running it at about 3.675


I'm impressed, only a little over a week of running it so far, and have gotten some pretty good results, though only 2meg SPI stable so far...

i take it you arent memtest stable then?

[Aleman]

@Gray Mole: Wow, 1.5-2-2-5-7-15 1T at 267mhz using "only" 3.675v Respect :).

[Gray Mole]

Don't know mate, I haven't used memtest since I got rid of my DFI board, it was all right when I had memtest built in, but too much trouble for now...

'sides...if you're not 32m SPi stable, you're not fully memtest stable, I would imagine...

and some stuff in the piccy...I think I like the ram at cas2 anyway for now, at least until I start heavily benching it again, waiting for some vmods on my card so maybe next week...


Still not quite 4 meg stable yet, but it'll burn in I'm sure, and if it doesn't...well I have 2 other 24/7 rigs, and they run tccd...I want more speed, not more stability, but that's just me...


Gray

edit, that was meant to have the spd for the VX in there :slap: not 2 of the same cpuz shots

I've added a sub-37 pifast in there as well, it ran 269 at 1.5-2-2-5 long enough to take that, but I didn't want to risk losing it to a blue screen :eek:

[andyOCZ]

so, i can rma my vx if it gets errors on 3.5v while 3.3v at the same clocks is stable!?

No, use what works for you. The higher voltage if for modules that like that much. The voltage you need depends on your board and CPU.

[Gray Mole]

I'm not really sure I'd understand why you'd WANT to rma sticks that will work well with lower volts...

Generally I've found that you add voltage to compensate for instability, not just for the sake of it...

If you find that 3.3v works, and then you up your speed or tighten your timings and THEN if you have instability you add a little voltage, you might find that 3.5v works for you...

My FX-55 is unstable at 1.85vcore...but rock stable at 1.73vcore, both at 3.2ghz...I'm not gonna complain about that lol but if I can get some better cooling that'll let me up the clocks a bit more, I may need that extra voltage to stabilize it, and may find that it ISN'T unstable at those higher volts when the speed is actually using it...

You see what I'm saying?

Gray

[Der_KHAN]

yep, i know what u mean.

but because my mem is fine at 260/3.3 i was really hoping that it would do 270 at 3.5-3.6v so i could run it 1:1

and i thought since ocz gives a lifetime warranty for 3.5v they expect all of their VX sticks to like that much volts

hey have you tried the new 510-2 bios for ultra-d mate?
my max vx overclock went from 264 to 268 so you might get those few MHz you need. ;)

Nice!

If they'll do that at 3.3, you might just get that with the extra volts...

How long have you been using them? After a while of burning in, they should stabilize at higher speeds I would think...

I had just found a setting for 270mhz that was working before I had some issues, so your will probably do that speed for you with a little playing, and possibly with some bios changes...

Mine is on NF3 Neo2, and your volts from the DFI(if that's what you're using?) might be more predictable that my booster...

yeay my vx does 268 in dfi but did 264 in the neo so pretty good for it.

[hpaco]

How are you cooling your systems?

Im looking toward the VX but I dont know want to have heat issues.

I have an arctic silencer for the cpu and a 80mmfan in front of my PC4400c25 (Lian Li PC-75 case), would be enough?

Also for a everyday setup would be better the VX or better kept my corsair sticks?

I want to change because my memory controller seems to be going to the dark side :) I used to get 300Mhz out of my memory, but now I get mem test errors even at specs (275mhz 2.5-4-4-6). lowering to 260 its ok, so maybe 260 or so is the new mhz limit to my memory controller and thats why im thinking about the VX's (no money to change CPU and some guy is in line for my memory).

update: oh I forgot I have an DFI Ultra-D so no problems about the voltaje, the proc its a 3500+ winnie

[sauria]

VX requires extreme voltage and runs hot but can take it.

Where can i get those VX!

Need them shipped to denmark!

just bought them in DK ...pc4000VX gold...... just running 2-3-3-8 @ 3v @ 250FSB right now...tried 2-2-2-11 but couldnt take memtest #5 ......i have them on my DFI nf4 and i think there was a way to give 3.5v in bios with just moving 1 jumper instead of them all for 4v option......what kan be expected at cl 2 @ 3,5v ???? and cl 2.5???

yeah go for it. an 80mm Silenx Fan is all I have blowing on them and it keeps them barely warm to touch.for everyday i still say vx. it will not give you heat issues.

[computer_geek]

ok i ran memtest it is strange the way it behaves as i started with test 1 it showed errors all over the place i then chose test 5 it had no errors right up till pass 97 then it would throw up 1670 errors so does this mean it just needs some burning in to get rid of these errors?

update : i now cant boot my machine i have a corrupted bios i have 2 bios chips both need flashing so i have to wait till monday to fix them up damn it
'

[BMORIN]

I had the strangest pair of VX that I've ever seen. It can pass '01 @ 270 but can't memtest any higher than 225 in dual channel. When I test the sticks alone they are clean through 265, but together, they error out over 225. Go figure that. But yesterday one of the sticks inexplicably died and are getting rma'd anyhow.

[Playful_Buffalo]

hmmmm, did you try any other stability tests (like 32m pi or p95)

[BMORIN]

p95 would fail over 225

[desolator]

just wondering which is better, the OCZ VX PC4000 1GB or the Mushkin Redline PC4000 1GB, im gonna be using it with an Abit AN8 Ultra and 3000+ venice

Just an update. I got my second stick working again 2 days ago. I'm running dual channel on 240mhz, 1.5-2-2-5, on just 3.25v here guys. Memtest error-free. This ram rocks a little too much :banana:

Nice TEDY. Keep in mind I had to have 618-2 bios and BankInterleave OFF to make mine happy, but 250mhz 1T @ 3.2Vdimm now, still waiting RMA to return before testing these at 4x512M.

HOW SHOULD I BURN THEM ???? suggest :=)

[pumbertot]

Just tried them a little

250 2-2-2-6 at 3.4v

HOW SHOULD I BURN THEM ???? suggest :=)

find a max stable speed at 3.2V then loop memtest 5 or 8 overnight.then try increase by 1MHz and do same next night.when not burning in(during the day) run them at say 200MHz 3-3.1V so they are taking a break. after a couple of nights up to 3.3V and do same.once you reach the 3.5V mark and highest speed then loop them overnight @3.5V and max speed. next day drop to 3.2V and run them in windows as normal with relaxed speed(less than their 3.2V max). then that night try to drop the volts as little as poss and try to run at the max speed they did at 3.5V.dont use memtest but use something like sandra bandwidth burn-in on a constant loop.repeat this method overnight using different mem stressors that dont halt on errors.hopefully you will reach the previous max clock on slightly lower volts giving a higher max clock at 3.5V.be patient and try this over a few weeks.


this worked great for me.they creeped up from max @ 3.5V 260 to 268/9MHz after about a week of this method.

[pumbertot]

I will try yes -1 or -2 ; Interlave OFF why ?

hm 250 at 3.2 is great result :)


stick to -2 works great.but try various BIOS once you find the max clock with burnin(above). I found hellfire modded to be best for me while others 510-2,618-2 etc.

[TEDY]

using 618-2 now....sandra bandwidth burn in you mean memory burn in ? :=) thanks

what settings did you used pumpertot ?

i have 4 sticks to test till monday when i'll keep 2 for me....how can i determine 2 best of 4 ? :toast:

the ones that do highest on memtest 5 at 3.2V are the ones to keep.
yes memroy burn-in.

settings, well start with these in order in BIOS.
1.5
2
5
2
8
15
3
3
2
2
3120
auto
en
auto
0
auto
level8
level2
8ns
6ns
16
en
16x
7x
dis

then you can maybe tighten some of:trc,trfc,twr,twtr,trtw,trrd,max async,read preamble once you find the highest stable clock.
e.g. trc=7 might be stable but may not. also I can run trfc14,max async 6ns,read preamble 4ns while others cant etc. so just experiment after finding highest speed poss after burn-in.

also try the 510-2 as i can clock about 10MHz higher than with 618-2 but may be different for you so find highest on 618-2 after burnin then try 510-2.

good luck and happy burning/oc. ;)

I posted this on Bacchus's thread. These are VX3200 Gold Edition. No tendency to develop #6 errors at max clocks in either SC or DC, plus running 270x10 with default LDT and chipset voltage. Only needs 3.5 VDIMM too.

No burn in. If you include the 26' to run 32M, the sticks have a total of maybe 2.5 hours run time. I've never run them under 3.3 volts.

Hi, to do 240mhz with the VX you will likely need at least 3.3v and a good power supply, although 507 passes and only 52 errors could indicate a heat issue. Do you have a fan blowing on your memory?


Running the Prime95 "Blend Test" is what is typically used for Windows stress testing.

[Moonman]

I removed a fan when I was measuring vdimm from a mosfet, so last 12 errors came in loop 586.
Before thist there were 40 errors, so it might be heat issue.

So you suggest to loop sandra mem?

Tnx for quick reply

I have a smal question. I have burnd in my vx over the night at 2.2.2.7 200 mhz at 3.2 v. Then I tryed 240 at 3.4 v but i got some errors in mamtest. Sholud I try to burn them in at 240 whit 3.4 v ? Thay got real hot when I run memtest and I got no god cooling for them. The only cooling is the fan that is sitting on my xp120. Do you think i need to get more cooling ?

[TEDY]

i don't get it really........why is this happening ?

[pumbertot]

i don't get it really........why is this happening ?


well i think its because in memtest the cpu onboard mem controller isnt too involved but once in windows stress testing it is so dimms need extra voltage for the communications between them and controller. at least thats my theory.....

[Moonman]

Isn't memtest #8 for windows stability?

[pumbertot]

doesnt seem to work that way though.

Anyvbody knows how this sticks owrk on DFI NF3 Ultra-D ( my board is great ! )

[eliminate]

I think that the VX is great and all, but if you guys really want to overclock your RAM, then you should have gone with the Mushkin RedLine. The RedLine can go up to about DDR587 or something whereas the VX cannot. I have two sticks on the Mushkin RAM and I am very pleased with them; I haven't tried the VX yet though.

[KingYubbo]

VX are super cheap... so even though it doesn't go to those massive speeds, $$$ > small increase in performance. For me anyway.... cos 250mhz VVX is great for me.

[[G.N.U.]Fragman]

well it isnt the RAM that are slowing me down..... 2-3-3-8 @ 250 @ 3.2v is possible....but my cpu wont go stable past 245 with less than 1.65 ....and this is close to my limit...its a 24/7 setup so it must be stable.......dont know how high to go because i dont trust those damn temp sensors @ board..... about 38-40 says ITE on load....XP120 and a 1100RPM revoltec on top.....that seems to me to little to be true.....

[KingYubbo]

does cas 1.5 work better than 2 with these? I have to use 3.5v to get 250mhz stable on DFI Ultra-D

[speed bump]

Apparently Cas1.5 does work with these and i'm not sure how much you gain though

[KingYubbo]

Anyone got a Venice running these with dividers and can tell me what settings they use in the BIOS? I'm having a little trouble with the dividers as it's giving me Primeing errors. Rounding times etc.

Hey Guys,

I heard the News BH-5/UTT don't run on S478 Boards/CPUs. They should only run on A64. I have some New BH-5 (noname) running on my S478 P4-M, but it doesn't work good. So this could be right. Can you say me some more about this? In some weeks I want to buy some new Ram and decided to take the OCZ VX Series with the new UTT. But do they run on S478 Boards/CPUs? Or must I take another Ram?
Please help me.

[Giana]

UTT/BH5 are WORKING on S478 . GOt some Twinmos Twister BH5 on my P4C800-E dlx.

[bullet2urbrain]

just a couple real quick questions

just got some OCZ PC4000 VX..... they are refurb'd tho... will i still need to do the "Burn in" process?

can someone point me to how to do the "Burn IN"

are the PC4000 tested @ 250 for sure.. my corsairs will run 250 but at super loose timings. i can give the UTT 3+ volts..

also which BIOS for DFI SLI-DR...........sorry for the repetitive question.

[dmo580]

Just burn them in 250 @ 2-2-2-10 @ 3.3.

I'm testing 257 2-2-2-5 @ 3.3. Looks good so far in memtest #5.

[dmo580]

I'm at 2-2-2-5 @ 259 MHz using 3.3V. I don't know if this is g ood or not. 0 errors so far after 10 min of Memtest, but Im surprised it didnt ask for 3.4v by now.... So far so good, but I'll leave it on for a few more hours

[Vapor]

That ain't bad dmo...of course we're all interested in what it can do with more voltage though. :p:

hi, first sorry my english is too bad

i bougth this kit today (i'm from chile) and go to burn process with memtest

i put the rams 200Mhz 2-2-2-x 3.2v but in less than 1 min there are aprox 32 errors

hi guys, i just recently bought a pair of 1gb kit ocz vx4000..

and i know that they suppose to work at 2 2 2 8 at 3.3 v... 250 mhz

so i use that configuration on my DFI sli dr, and it doesnt even boot to windows, seems that the screen freezes and the windows boot logo never appears :mad: .. i have even try to 3.5 v and no luck :confused:

so i tried to 245 mhz and apparently boots but with a lot of effort and unstable i suppose..

so im actualy burning in my ram at 2 2 2 6 3.3 v 250 mhz, and it appeared thousands and thousands of errors in test 5 in memtest 86..

do you think after i burn them for about 24 to 30 hours my problem with get solved?? or should i just RMA them :(

thanx in advance :toast:

[AMDfan]

what's your Bios version ? :confused: you may have to reflashing your Bios, and check if you got the right timing seting :scope:

[ZeroX]

With the burning u can increase the rams performance, but thousands of errors in memtests is too much.
I think is a bios problem. Try another bios what works well with UTT ram. Ask for recomendation...i heard that the 510 run well

/OFF

Tienes que flashear otra bios. Hay bios's especificas para rams con UTT. Pregunta a ver, pk yo no estoy muy enterado (no tengo nf4 :rolleyes:)
Y el burning se hace con el memtest dandote algunos errores... no miles xD

Did this get resolved? It sounds like your BIOS version/slots or settings are the problem. The VX (and any RAM really) needs special tweaks on the DFI NF4 to work properly.

Let us know.

[varzmaster]

Nice to see you guys watching out for such cases! :)

Clearly this is not a RAM issue. I remember my first trials with BH-6 on the DFI LP UT nF4... wasting a whole night to get them working 270 MHz 2-2-2-5 @ 3.8V stable through Memtest86+.

zalman fan bracket with a silent 120mm fan mounted over them.they are barely warm @ 3.5V. i use this over any memory.

ps.the vx is for sale on here. ;)

[gallardo]

I'm having a bit of trouble here... A friend of mine has asked me to help him with his computer (which I advised him to buy) and I can't seem to get it working properly...
The system:
X2 4400+
DFI Lanparty UT SLI-DR
OCZ VX PC4000
BFG 7800GTX OC (damn thing stays right on top of the northbridge cooler)
Enermax Noisetaker 600W
Thermalright XP90C + A.C. Ryan fan (I tryed with it at 2500rpm and it's the same as 1300rpm)
2x Maxtor 250GB 16MB NCQ in RAID 0

First, after he set it up, I saw 79800 points in Aquamark 3. After we put the new BIOS that recognized the dual core and we set up the RAID 0 we tryed again. Same drivers, same Windows with just a SP1 and without a video card oc. We got ~75000. Were did almost 4000 points go? We didn't mind so much... Next we tryed to make the RAM work as it should (it was at 2,5-3-3-8 at DDR400 at 2,6V until this point). This was without putting the jumper for the 4V for the memories. I tryed 3,1V and 2-2-2-5 at DDR400 (i didn't tweak the other settings as I really needed a guide for it... there are simply too many!!!). Went into memtest and we had errors.... Ok, set it at 3V and surprize, it works in memtest... Wierd. Super PI was not stable, though (32M). We left it default at 2,6V until I got more info about the various settings.
After I read a guide for the memory options in the DFI BIOS, I went back and this time I put the jumper for 4V (I said maybe it couldn't give enough voltage for the memorys since it was drawing power from 3.3V). (BTW: damn, there are soooo many power cables you have to connect for the DFI!!! Very power hungry!!!).
3,1V, DDR400 2-2-2-5 and default for the rest of the memory options (the things suggested in the guide gave me a nice beep after restart... It didn't work!). Memtest... reporting errors again. 3,2V. same thing. 3,3V same thing. After 3,4V and seeing errors again I was furious! I put 3V and the errors dissapeared. %@$*@$@
Of course, at more than 3V it was stable in PI 32M. At 3V it was not completely stable. Ok. I said to myself that this mainboard is not for default values. I overclocked it. 250x10 for the CPU with HTT at 1000MHz, RAM at 1:1 with the FSB, 3,3V and 2-2-2-5. Errors in memtest. Not stable. 3,4V and 2-2-2-8 (and less voltage for the CPU as it only needed 1,45V <<1,4V recognized in Windows>> to be half an hour dual prime stable... BTW, I know I shouldn't have just overclocked it to 2500MHz like that, but I was furious... lucky it worked! :D ). Errors in memtest, stable in Super PI 32M. Now what?

I have tryed with other settings in BIOS for the RAM and with default ones.. Memtest just keeps showing errors except for 3V DDR400. What to do?
BTW: We didn't burn in the RAM as we didn't thought it was needed. On the OCZ web page it says that it is certified at 250 2-2-2-8 3,3V. Well these don't work! What to do? I am waiting for a response from an official maybe...
Please help! He's gonna kill me for recommending him a DFI and OCZ VX...

[Jacke2k]

Burn them in att 3.3 v and 250 mhz 2.2.2.10 and it should work.

[RyderOCZ]

VX PC3200, too bad 12x wont do, but quite nice.

http://img.photobucket.com/albums/v636/loc_oc/spi1M273loc.jpg

[gallardo]

RyderOCZ, i have tryed the settings you suggested at DDR400 @ 3,3V and there were errors in Memtest (after like 5 seconds it starts counting errors). I set the memory at 3V (same settings) and it did about 10 minutes of memtest without any errors (test #5). Why? How? I didn't try the BIOS you suggested. Is it new enough to support Toledo X2 4400+?

[RyderOCZ]

Yes it is the newest bios for the motherboard, it support Toledo just fine.

If you are getting 250 with 3.0V....that is awesome :D

[gallardo]

No, it's not awesome! It's stupid! DDR400@3,3V sux in memtest. DDR400@3V stable in memtest. How is that? And the 3V is with the jumper on the mobo set to 3,2V max!
DDR500@3V won't even start (I tryed, thinking it'll be memtest stable :D ) and at 3,3 AND even 3,4V it's not memtest stable... WTF?!?
My friend did NOT pay 200$ for a pair of sticks that are COMPLETELY stable only at DDR400 2,5-3-3-8 @2,6V!!! What is going on???

[RyderOCZ]

Send me an email....link is in my Sig :)

Thank You.

bought a caa2c dfi sli-d and ocz vx 4000
i had the best 3 weeks of my ...still short....OC life...till the they died on me....
i could go up to 267 1,5-2-2-5 with 3,4v....i was amazed....rma time.. :slapass:
2nd pair arrived..."only" went to 261...3,35v... :toast: ....i was happy again.....till they died on me again....30 days later,even with a noiseblcker S4 in front of the mems....rma time again
3 rd pair arrived...well 250 3,3v seemed like conservative settings for this kind of mems...but i was happy again...250x11 was enough for me....
then it happened again....3 rd pair went to meet the maker...
its my shop rig..so i dont bench and throw volts at things cause i am working and i need a solid ,fast and reliable machine....i have a venice and an old pair of bh6 to bench at home.....
tony from ocz and sean were very nice and took care of the rma for me...i just need to send it to california....shipping and vat on the return will cost me about 180 dollars....150€.... :dammit: no go...to much money
ppl say dfi kills the mems....why does it killl only this kind of mems
i have bh6 and ch5 and i stress them a lot more than i did with the vx...even some ogrish things like 3,6v ...ya thats extreme for me

There is a huge thread covering this subject, in this thread you will see members with old BH5 from corsair and Kingston having just the same issues, One dimm dies.

Im sure we can work something out on RMA with you, i have instructed support to contact you.I would however ask you to move away from using VX.

It is the CH UTT chips, they are not durable like the old BH-5 but they do clock well. Lots of peoples RAM has died with 0 abuse and below stock voltage. I had 2 sticks of UTT CH die (so far..) and I wasn't too happy when my primo 270Mhz Redline died and I had to garbage it. =/

[Vassili]

@ steelballzz
Do you use the 4Volt jumper? Because if so don't, because the 4Volt jumper can only work properly if you go past 3,5Volt (or maybe even higher). With less the mosfet is getting way to hot if it ain't cooled extreme.

yes
i need the 3,3 to feed the vx....
i am running some mushkin special bh6 for a couple of months with 3,35 24/7...using the jumper...

i am using the new vx kit in a new dfi....brand new.....with 623-3 shipping bios...running for 4 days..so far all is good...except for the speed of this ones...255 3,4v....worst kit i had so far....but i will give some time and see if they can go any further.....
i dont have an ocz psu so i canot perform the trick with the jumper to avoid the 4 v
