Wt* is wrong with my Vcore??

post #1 of 9
Thread Starter 
This is ridiculous guys, I can't get a solid 3.2ghz overclock on my brisbane because my vcore is fluxuating so much, it goes all the way from 1.52 down to 1.456, its driving me f-ing nuts, why is it doing that? when I set it to a certain voltage, why doesn't it stay there? my GPU's voltages dont jump, my NB voltages don't jump...

is there any way to fix this?


and on a side note, is there any way to NOT use vcore over-voltage on an ASUS board? no matter what option I choose (enabled, disabled or auto) it still over-volts my vcore by a minimum of .2volts

so ive got it set in the bios at 1.3125volts with over-volt enabled (I don't trust auto) and it idles at 1.51ish, but the SECOND I start running ORTHOS it immediately plummets down to 1.45, and it makes it so i cant go any higher, because I don't want to compensate for the vcore drop by adding more volts, because then I'll be idling at like 1.54 which is crazy, but my 3.2ghz overclock isnt stable at the 1.45volts that it drops down to when i have it set lower...

wt* do i do?

AMD boards don't have vdroop. Intel thing.
Vdroop is an Intel specified design where vcore drops during cpu load.

So under load it will fluctuate, or just between idle and load, because cpuz reads your voltages dynamically

so if vdroop is intel-only, why is my AMD processor doing it?

and do you think it would be safe to just compensate for it and run my proc idle at 1.54? or is that too high for the chip?

right now my chip idles anywhere between 27C and 32C and under full load will be anywhere from 38-42C

fluctuation as opposed to intel vdroop (consistant drop at load)
I would guess either your board pwm, psu, doesn't like delivering the voltage. Your home electrical system has spikes. Or your cpu has voltage leakage. Could be a lot of things.

My thoughts would actually be on the PSU being unstable under load. If I'm not mistaken, that HD3870 pulls quite a load!

hmmm... what do you mean by the board's PWM? because I don't think its the PSU, and its probably pretty unlikely that one of AMD's "energy efficient" processors has voltage leakage :/
