Hi guys,
I have searched but cant quite find my answer.
I just purchased an ASROCK Extreme 4 Z97 mobo with an i7-4770k. I am also using a Cooler Master Hyper 212 Heatsink. And I started doing stability and overclocking tests yesterday, only to find out that I have to put 1.25V for the CPU core to get it there. First Prime 95 (blend test) runs for 5 minutes at about 72-73C, after 5 min it increases FFT Size (i think that's what it does) and my CPU core Temp goes to the 90-100 and starts throttling and I have to stop it. I may have let it go for around 40-60sec at that temp before stopping it. I couldn't get my damn system stable at 4.2GHz. even at the stock speeds (3.65GHz) all 4 cores goes to 70-72C on Prime95 at the larger FFT (after 5 min), the first 5 min Prime95 runs at 60C. I thought I had the worst i7 untill i started thinking about my thermal paste application.
It's Been a while since I installed a CPU and immediately started realizing the error of my ways... I put a whole freaking tube of Arctic Silver 5 on top of the CPU *facepam*. Still at idle it would run in the high 20C and gaming in the 50-62C... however Prime95 really put it trough it's paces.
I wil be removing the glob of crap that I put on there and do it properly this time BUT i am still worried that the CPU might be bad. I had to crank it all the way to 1.25 for a mere 4.2Ghz in order to run Prime95 for the first 5min. I crashed pretty much every time before that.
So, my question; is my poor thermal paste application the reason why I have to put 1.25V to run 4.2GHz? Why does Prime 95 "explode" after 5 min? And last, what temperatures should I be aiming for this torture/stability test?
Thanks!
