WTF K8N Neo2 Undervolting is huge!

[Mrvile]

In bios I have my vcore set to 1.55 and my overvid set to 5% but I'm still getting like 1.5 - 1.52v according to CPUz and Everest, this is so stupid! Is there any way I can actually get it higher??

 

[Yossairian]

Try going lower vcore, like 1.45 or so and a higher %% like 8.3 or 10%. I was able to get it up to 1.65 or so before I chickened out heh..

 

[Mrvile]

Well I changed it to 1.50@8.3%, bios tells me anything over 5% can be unstable but what the hell. CPUz says 1.55ish now. Ok time to run P95.

 

[Mrvile]

Wait when running P95 I'm supposed to run the in-place Large FFT's test right?

And before I finished this post I errorred out. I'm trying to get 2.7ghz stable on my 3500+ Winnie, back to the drawing board.

 

[Mrvile]

Agh I'm at like 1.56 - 1.58v and I'm still erroring out in P95, yuck!

 

[Yossairian]

Yeah I couldn't pass P95 ( The first selection on torture test ) until I was down around 2500 on my 3200 chip. Right now I am at 2450 w/ 1.5V. I will probibly leave it there for awhile.

 

[Mrvile]

Ok. Well I'm at like 1.61 - 1.63v now (1.5v@10%) and I hope I don't break anything, running P95 now.

Is it bad for the CPU to be running <1.6v at all times? If it is then I'll push her back down to 2.6ghz at like 1.5v.

Also, my CPU temps are near P95 max load temps at bootup. This is supposed to happen right?

Wow P95 ran stable for the duration of me typing this, temps are max around 52.

 

[Mrvile]

I jinxed myself, she crapped out on me after 2 mins. F it, 2.6ghz is enough.

Is it always voltage that causes the errors in P95?

 

[Mrvile]

Help, is there anything I can change besides voltage that will help run P95 stabler?

 

[ChineseDemocracyGNR]

Make sure you're not getting errors because of memory issues by running memtest86+.

 

[Mrvile]

Shouldn't be, my ram is DDR500 and my FSB is 246.

But anyway I change a bunch of things, I set my HT to 3x, multi to 10, FSB to 260, vcore is 1.5@8.3%, ram voltage at 2.75 @ 2.5-4-4-8 1T. Running P95 now, everything stable so far. Damn I wanna hit 2.7.

It could be. Your memory controller only supports up to DDR400 officially, anything faster is overclocking and so may cause errors. Companies who sell DDR memory as DDR500 are being optimistic to its overclocking potential, and didn't necessarily test that configuration on the same motherboard, BIOS version and AMD64 revision that you have.

The board does undervolt by about .05v.

Here are what prime tests you want to run:

8k FFT, in place - test FPU
512k FFT, in place - test cache (although RAM errors will still show up here)
4096 FFT, not in place - test RAM (set RAM to test to about 2/3 of your total memory capacity to avoid disk caching).
