Hello,

I have this setup which prime stable for 9.xxhrs but OCCT failed. Should I worry about it? Also, I set cpu voltage to 1.5v in bios but smart guardian says cpu vcore is 1.39v. Which one is right. Thanks for all the help

DFI ultra-d
opty 144 @ 310x9 1.5v
2x512 pc3500 kingston 2-3-3-7
500w modular antec sp
raptor 36g
evga 7800gt

Sorry about my ignorance, but do they have Vdrop in AMD world like they do in the Intel world.

That reminds me of my mobo. If you don't set CPU Overvolt on (which adds .2v and kicks in the 8-phase power, so if I set to 1.3 I'm really gettting 1.5v), the voltage on my A8N32 goes from 1.4-1.5 all over the place. It's insane.

2)My CPU at 1.425V, passes Prime 7h 58min, fails 3d mark 06 and 05, but passes super pi 32M as well
at 1.4375, passes 3d mark 06 and 05 and maybe 01se as well, but fails COD2 demo
at 1.45V, passes COD2 demo as well

Are you freaking stupid? The PSU he has 17A and 19A on two 12V rails. Stop giving people advice when you don't know wtf you're talking about.

please note that i now use ocz psu and still have the same problem. I'm using a memory divider, which i don't remember which one but it's the one that make my ram run @200mhz, i plan on using different ram to see what happen

 

[cuti7399]

using different make no different. Now i'm don't know what's else to do. Help

Does your BIOS have an "Overvolt by X%" type option? As a previous poster mentioned, I have seen boards that fluctuate a bit if you just assign the voltage, but report stable voltage if you give them a % overvolt on top of it.

Cuti, you never said what RAM you're using, or has your Mushkin come back from RMA? If so, which type is it? These Ultra-D boards have to be tweaked for each and every type of RAM, to be stable, like all of the other DFI boards. It most likely has to do with your DRAM Drive strength and/or your Tref settings. Post back with the exact RAM you have, and I can tell you the settings for it.

i have the mushkin pc4000 ram in there now. running 3-4-8-3 @2.7v. please tell me if the setting are correct, thanks myocardia

cuti, Mushkin makes more than one type of PC4000. I'd need to actually know what the package it came in says it is. Unless you happen to already know which IC chips it has?
