So basically I've been tinkering with an overclock in my system, its my first PC build and the specs are in my sig. I have my i7 clocked to 3.6GHz, a modest overclock but I don't want to push things higher yet because I want a rock solid OC first.

Its been pretty stable, I've put in hours upon hours of gaming with the OCed settings over the last few days (just got my wisdom teeth out so I have time lol) and have run into no issues whatsoever. No freezes, no BSODs, nothing. My buddy recommended I run prime95 just to be sure.

I ran the small FFT test with no errors after an hour. The large FFT test ran for an hour and got no errors too. I decided to run the large FFT test once more just to make sure, and one of the cores failed after 5 minutes. I was using Firefox and Trillian in the background when the second large FFT test was running, would that make a difference?

So i'm not exactly sure how to proceed from here. Pics are below if you guys wanna take a look at my settings, any suggestions would be great.

One thing I just tried is setting all of my RAM timings to auto in the bios. It changed the timings to 11-11-11-24 with a tRFC of 128. With this change I made it through 3 hours of large FFT testing in Prime95 with no errors, but I'm assuming im slowing things down with these timings. What do you recommend?

thanks for your help too :)

Thanks for the suggestions. I'm at 2 hours of large FFT testing right now with no errors and 7-7-7-20 timings. I'll let it run for another hour or two, and if it looks good i'll run a Blend test overnight. Thanks again!

I let the large FFT test run for 3 hours, no errors. I started the blend test 3 hours ago and its still going with no errors, looking good so far. I'm going to go for 8 hours minimum with the blend test, maybe 16.

Blah I wish I had seen your post sooner, I stopped the test at 8 hours. No errors though, and the 15 minute mark was hit regularly from what I can see :D

I ran Intel burn test on Standard and High too, both were successful. Looking good so far.
