OCZ VX, Best Memory made since BH5!!

[FiNcH64]

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 .. i have even try to 3.5 v and no luck

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

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

[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 )
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.

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+.

Hehe, yup! Been there...........

[pumbertot]

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.

what you are saying someone had mushkin redline @ 293MHz 2-2-2-5 and you are saying it as if they all do that impossible figure? i highly doubt it, lay off the drugs man.

I have the vx pc3200 and I have tested them att 235 whit 3.3 v and hade 4 errors after 25 h. Now I'm changing my motherboard from msi neo 2 to an dfi sli-d. what bios should I use for my vx mem ?
And do you have any tip on how to get my mem higher ?

623-2 BIOS. and put 3.5V into them.

Yr right, Auto now, me bad. 4 was in old 510-2.

Anyone have tried 4x512 VX´s on NF4 Ultra D ?!

[pumbertot]

Anyone have tried 4x512 VX´s on NF4 Ultra D ?!

yes i have 4x512mb PC3200VX running here on Ultra-D 2-2-2-5 2T 260MHz @ 3.5V.

[Jacke2k]

yes i have 4x512mb PC3200VX running here on Ultra-D 2-2-2-5 2T 260MHz @ 3.5V.

How do you cool it ? I can think it get realyt hot

[pumbertot]

How do you cool it ? I can think it get realyt hot

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.

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! ). 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]

@ Gallardo,

What bios are you running? I recommend the 704-2BT...download it here: http://www.bleedinedge.com/forum/showthread.php?t=9917

Then try these settings:

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

[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+?
