Getting 990x to 4.4GHz

post #1 of 3
Thread Starter 
Okay I've been overclocking my 990x and have run into a problem that baffles me. I can get the cpu to 4.3GHz and have run prime95 for 15 hours with no fails. now I'm shooting for 4.4 and I cannot get it to run for even 40 mins without it failing. now my first thought is the memory being too slow and maybe needing to get faster ram to make it more stable. Just trying hit that 4.4 GHZ mark. Just looking for some tips.
Thanks.
Oh, the temps at full load are running at around 47c(after 8 hours) and 34c at idle.

Hi,

Are you running manual in the bios as to your setting?

Need more info.
Not into the 6 cores, But basics are basics when it comes to the 9xx chips.

Try cutting that ram in half.
QPI voltage needed for that much ram as you clock it up.
What are your ram specs??
Running tri channel??
Temps with the H100 loaded??

Help from the six core crowd if needed!!

I had my 980x up to 4.65ghz stable, but took 1.55v 65c load with my chilled water. You should be able to get 4.5ghz easy. Even 4.75ghz with great temps. Can you upload a couple pics of your bios so I can see. I had the Rampage 3 Extreme. The Evga bios are a bit different.
