Need help stabilizing 5Ghz OC for 2550k

post #1 of 4
Thread Starter 
Hey guys I got in on the microcenter deal recently and I've been trying to stabilize the 5ghz OC for the past two days.

Aside from the 2550k and the ASUS P8P68-v Pro the rest of my components are the same.
Vcores I've tried have been 1.42-1.46. Starting from 1.42 the system is primeable for at least an hour however I keep getting BSOD 124 error codes. The higher the vcore gets the longer it takes to fail, but fail it does anyway.

Depending on the Vcore/room temp my load temps are something like high 50s to mid 60s.

I read that a 124 code may either be caused by vcore or VCCIO. I just upped the stock VCCIO of 1.05 to 1.15 and dropped the CPU PLL voltage to 1.7v (as I heard its stabilized systems for some)

Is it normal for Intel CPUs to run like 8-10 hours and fail? I would think if it was unstable it'd only take a few minutes... Thats why this process of stabilizing it is making it that much more tedious as I have to wait half a day just to find out its unstable.

I was thinking it was ram related since it takes so long to fail. My corsair ram is set for 1333 9:9:9:24 and I've set it at default for now but on my previous build it was perfectly fine running at 1600.

Any tips?

try changing your timings to 9-11-9-31 and see if that helps.

what are you cooling it with to get those low temps? im assuming its on water because mine runs hotter then that @ 4.5 on a 212 evo with 1.410 vcore.

i cant get mine stable past 4.5 either. go up to 4.6 and it fails prime after a few hours even with another .05 volts.

Drop your RAM to 1066 and see if it happens. I believe it has something to do with the strap because my ram works flawlessly in every other PC but my 2550k. Then again it might just be because the integrated GPU is disabled too rolleyes.gif
