vcore creep and instability

post #1 of 5
Thread Starter 
Processor : i5-2500k not OCed (yet!)
Mobo : Asus P8Z68

so the problem im having is, my vcore keeps creeping up the voltage

this was the worst it went through.



when it just powers up, it starts normal, the vcore caps at 1.2v like stock. and depending on the load i put on the proc, the vcore keeps creeping up nonstop until it just finally decided to shuts down.
i never have a BSOD, and the computer rarely restarts, usually it just shuts down like it's terminally overheated, which it is not. the temps stays at most at mid 80c



i don't understand, nothing looks like it's making it unstable. i'm already on offset +0.03 on the bios with stock speed, but i can't really see the effects because of this voltage creep.
i've googled for a whole day to find nothing.

it also couldn't pass any stress test i put it through. not even the short 3-5 minutes one even with the offset and stock speeds.

midway through it just instantly shuts down. no instability warning, temps still okay, vcore not that high yet. but it's still, usually around 2-4 minutes it the stress test (either IBT or P95) it just gives up and shuts down.


even when i'm writing this, it started at 1.288v and now it's at 1.672v.

restarting doesn't reset the vcore to normal, since it doesn't really shuts down the mobo. but shutting down and powering up again does. and sleep mode does.

anyone have any clue?

I don't know but maybe you have significantly reduced the lifespan of the CPU running at a voltage that high. Heck anything over 1.4V is already pretty bad.

Adjust load line calibration and/or use a manual voltage. There is no reason to run the computer right now with more than 1.4V at stock speeds.

LLC are enabled. and my mobo doesn't allow direct voltage control. just voltage offset.

i think the offset control is running rampant.

i can play KSP with +.01 offset @4ghz without any problem/crashing dll, and seeing hwmonitor, it averages at 1.4-1.5, and never past 1.68. but as soon as i start stress testing. it shuts down in <5 minutes.

and i think it caps out at 1.6ish... which is stupidly nuts.

Are you able to use a negative offset?

could. but again, because of the vcore creep, i couldn't really notice any difference
