Set you CPU and IOH skew to 300. Set your PLL to 1.7(if this boots go to 1.6, if that doesn't boot go back to 1.7, this is an undervolt, but it will help your OC.)
I did everything you said and managed to boot up successfully. When I tried to run a stress test at 4.0GHz, my computer locked up and I got a BSOD of 009x I believe. I then went down to 3.8GHz and everything seems to run fine. My temp still idles around 45c (I managed to lower it with your configuration), should I put some new paste on the CPU/H50? I'm still using the stock paste that was on the H50 and I had to take the H50 off and put it back on twice already. I have purchased after market paste, I just never used it.
I turned the CPU Fan speed (H50 is plugged into) to turbo and turned all the other fans (HDs, H50 radiators push/pull) to lower speeds in the BIOS. I purchased some new cooler master fans
and they are loud and the only way to quiet them is to lower the speeds in the BIOS.
If you have any other suggestions on how to quiet/cool my machine down or achieve the 4.0GHz and be able to stress test without crashing WITH my current setup, please let me know! Thanks so much for all your suggestions everyone, I just wish I knew what I was changing and how it was effecting my overclock! (tconroy135)Edited by jodriscoll - 1/7/11 at 7:11am
