OCZ VX, Best Memory made since BH5!!

[Jacke2k]

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...

So the vx works fine on he neo 2 board ?
My mem dont like this board I think cant get it over 210
Have tested v from 2.9-3.6 and all sorts of bios
So my next mem will be vx

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

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.

[Sila]

Where can i get those VX!

Need them shipped to denmark!

[[G.N.U.]Fragman]

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???

Question folks:

What are the steps to make use of the OCZ warranty if my RAM ed up?
Does OCZ offer an OnlineRMA method or what is the usual procedure?

I am from germany btw so maybe its a little bit different for me.

[computer_geek]

hi all extreme overclockers

my new ram arrived ocz vw 3200 1024

so far i have got it to 240 on 2.9v cas 2.5.2.2.8

my specs are

xp3000
nf7-s rev2.0 with all volt mods done
gf2ti
1024 ocz 3200vwd

Turn up the voltage and run CAS2 instead of CAS2.5.

[computer_geek]

ok i have upped the volts to 3.1v @240 as soon as i go 242 bsods on me
any suggestions please ?
this is the bios i am using ABIT-NF7D10-MantaRaysXT-2T

[Aleman]

Before even entering in Windows, check your stability with Memtest86 v1.51

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

[Damien]

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

[TEDY]

Just got this puppies from a friend in USA



whole weekend of testing ahead

[Magnj]

Yea my mem is real good. At one point I managed like 250 2-2-2-10 memtest Eroor free for hours. But my mem controller can't handle 2-2-2-10 at any speed I have to run 2-3-2-10

[uwackme]

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.

[TEDY]

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

hm 250 at 3.2 is great result

[TEDY]

Just tried them a little

250 2-2-2-6 at 3.4v

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

[pumbertot]

Just tried them a little

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 ?

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.

[pumbertot]

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

both are great have tried both.ocz rma and support is 2nd to none so id pick them for backup.

[TEDY]

after some burnin i get 245 at 3.2 , when i got they barerly did 240 at 3.2

yummi :=)

[[G.N.U.]Fragman]

100% stable with 1T 250FSB 2-3-3-6 @ 3.2 ..perhaps i can take it a little more...

[TEDY]

why 2-3-3-6 ???????????????????????????????????

[Aleman]

why 2-3-3-6 ???????????????????????????????????

Coz UTT-CH based OC´s higher with a little of looser timings.

[bradmax57]

Coz UTT-CH based OC´s higher with a little of looser timings.

um slightly out of place i spose but my ch-5 ram will do 265 2-2-2-5 3.3v (tis not ocz tho)

[TEDY]

Holly cow, this ram getting better and better after BURNING IN

Now i'm at 254 2-2-2-6 at 3.2v

[Clevor]

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.

[Moonman]

This is with my VX3200. Now running at 200Mh@3.2V prime "large, in place FFTs - stress ram". Is this good for burn in or should I use sandra memory loop.

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

dpont be so lazy.the previous page or one before that I explained how to burn in.read lazy man. :p

[Moonman]

Done, now burning at 246Mhz 2-2-2-8@3.35V
Tnx for guide.

[pumbertot]

no probs matey.
btw tRAS gives best bandwidth at 5 and I find it just as stable as a number >5.

[Jacke2k]

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 ?

[Der_KHAN]

Do you think i need to get more cooling ?

yes.

[TEDY]

yuhu

DC 250 2-2-2-8 3.2v

slower ram in closest orange slot + better ram in farthest orange slot

[TEDY]

lol memtest#5 no errors but when i try superpi......doesn't even start, where's the catch ???

[Aleman]

TEDY @ tried tRFC @ 16?

[TEDY]

yes that's why it's weird

here's pic of A64 TWEAKER

[Jacke2k]

How did you get it to 254 whit only 3.2 v ? My need 3.4 and still I get errors in memtest. I got 12 errors after 9 h of memtest.

[TEDY]

got lucky

[Jacke2k]

I want to be lucky some times to =( :P

Tedy my mother is from Slovenija

[Moonman]

TEDY Tooo lucky

My 3200VX also need 3.4V for 250Mhz 2-2-2-5

[pumbertot]

TEDY Tooo lucky

My 3200VX also need 3.4V for 250Mhz 2-2-2-5

mine do 260 @ 3.2V in memtest all test al day but need 3.4V to be fully stable in windows such as S&M stable.

[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]

Isn't memtest #8 for windows stability?

doesnt seem to work that way though.

[[G.N.U.]Fragman]

my new SD 3700+ wont go beyond 240FSB so perhaps the bios could be the bugger (310) so which one for my pc4000VX would be the best (wont use 7** ) ? 526 sounded good, but dont know what changes have been made in the 6** and what version to choose.

[Viss]

I would go for 510-2 FIXED (23-06-2005)

[[G.N.U.]Fragman]

just tied with 623-3 ...worked fine at 220FSB it didnt need any extra vcore....but then it was like hitting a brick wall.....230 1.5 in vcore!!! and only stable 240@ 1-6v ....this is very disappointing.
