Increase more if needed but do watch out for the NB temps....put a 80mm fan if you feel need to...
It should spike or drooping but not 0.1v around 0.02-0.04 is max...imagine u set 1.400, what u really did was actually pumping 1.44v 

So thats why I said who need to use MM to ensure the value of the OV...UV not so much a problem...but when the difference is too much...then either PSU or mobo regulator kaput already...



here u go...

i tried setting like that but all value setting i set still fail on worker 1 prime95...the worker 1 is cpu0..this worker always fail every value i set in core0.
maybe cpu0 is bad core?.no chance to make core0 stable?..also i add more voltage on cpu,nb n ht..nb freg 2000mhz..or miss something?

@antonio..
thanks

the problem persist.... mebbe i shud give the system a rest 1st and see later...

Please fill in ur settings...can't imagine..

every setting i set in acc value still cannot make it stable..still fail during prime on worker 1.

worker1=fail
worker2=ok
worker3=ok
worker4=ok

in AOD also stability test fail on fpu test 0 will make AOD hang..but cpu test 0 can run..if run both will make AOD hang also.
hope expert here can solve my prob until this proc stable.

brader..u are very lucky to have unlockable 0915..
how about increasing some vcore 1st..
this is fundamental step to make unstable proc, stable...

Try the above

If fail...I eat my mouse

i tried your setting.i set
Cycle Time (tRAS) : 18(max)
Bank Cycle Time (tRC) : 26(max)
CPU : 1.4v
RAM : 1.93v
HT : 1.36v
NB : 1.25v
ht and nb can't set individually..if i set ht nb will rise together.

still fail la.

hah. apa lagi?? kasi makan itu mouse la.

*Grruupp grrupp krrakkk...burp!!

hhhmmmmm.....how come fail...hmmmmm..

Is your rams memtest86+ proven???

i tried memtest already all ok no error..
so anymore solution?..

Check out the changes i made...

It should work as previously the voltage for the CPU-NB isn't set...try change the value and see if the IMC can handle the unlock cores

if i not mistaken my mobo don't have cpu-nb voltage control..

Ur using Asus EVO??

try update to latest bios...

huh asus?..no la..msi la..

already updated with latest bios.

mind to let us know what is ur CPU Temp??

default idle 45'c load 58'c..unlock idle 50'c load over 60'c..this temp with xigmatek apache..just bought cm hyper 212+ still not install yet.

aiyak...no way to control IMC voltage??? I returned my few hours Asus 785 EVO because of that...hihihihi....

no...just have cpu,nb,ht link,ram voltage setting..

sorry, what is it mean ?
and why my buzzer still will beep when i at xp loading screen? ONLY AT XP LOADING SCREEN ..
