What does this mean?

post #1 of 40
Thread Starter 
So I've been overclocking my rig a bit, and got stuck at 2.6
I let it run on prime and noticed something when I checked my everest
VCORE: "Min: 1.39 Max 1.47 average 1.45
and its not running stable usually.
in just one min it does:
1.46
1.41
1.46
1.42
1.44
1.46
1.41

now,that doesnt look to good....
My psu has :
Silverstone 650W
33 on 3.3
24 on 5
four 12v with 16 on each.

Try verifying that fluctation with Asus' PC Probe. Maybe it's an Asus quirk. Is your system stable on Prime for 12+ hours?

My P5B-D fluctuates betwen 1.33 and 1.34, though over long periods of time (hours).

Most voltages fluctuate some. Pretty normal. As long as you don't expierience any instabilities like random crashes, bsod or lock ups, I would'nt worry about it.

Look in the spec's of your cpu and see if it has a variable voltage..Is the v-core set to auto in your bios? If you have a variable v-core chip and v-core is set to auto that could account for it.....Look under the "Advanced Jumper Free" configuration in your bios for your v-core settings...

Many have had luck enabling CPU Overvolt in the BIOS. Be aware though that this adds 0.2v to that is set as Vcore. So lower your Vcore also.

Is that set to auto, or what you have set it to? If that is what you have it set to I dont know what would be giving your v-core jump...Maybe you should check the voltage on your molex's with a multi-meter and see if you voltage is jumping there to...If it is it might be a PSU Problem..If all the voltages on the PSU rails are O.K. I really don't know what it is...

I set it to 1.4375(might have bumped it to 1.45 last night.

Ill get a meter right now

That really isn't a big bounce in v-core voltage...But it does not hurt to check your rails they will have a little bit of variance, but it shouldn't be alot.Check it against the spec's as supplied by the manufacturer to see if it is with in spec's.....If everything looks O.K. your instability may be due to other things in your O.C.....

I got the mobo max, ram max and put my CPU as high as it would (with ram divider at 100, HTT at 3x, etc)
Though, is overvolting NB/SB important for anything of this sort? Im worried about upping mobo because it usually is running hotter than my CPU (acording to every temp sensor Ive had, prolly the heatpipe issue I just dont want to take the whole thing apart again)
Ill try overvolting and things tonight, I just got home from a movie.
5V is at 5.13, Ill check the others once I pay some things and send some mails.
