Rampage Formula and a 45nm CPU? READ THIS!

[JohnMike]

My Rampage is working fine and stable (Prime95 Small/Blend proof) with my E8400 (4Ghz, LLC enable), but last weekend i was playing COD4 on-line for 2 hours and on a full action scene, sound disapear/black screen and game off to desktop with a #.exe error.

Fire up the game again and no problem at all. This type of issues (multimedia/web applications also) happened to me alot when i had Asus Formula SE (random BSOD). With my ex-Q6600 GO had no problem at all, run for hours, weeks, months total stable without any issue.

I thought that with Rampage these types of issues where gone, because i find Rampage way better board than Formula SE, but seems that this weekend issue was/is an alert.

Just do a pencil Mod and disable the Loadline Calibration. I was watching CPUz go crazy with fluctuation in Voltages prior to making this change. Prime would system reboot constantly. With the Pencil Mod in place, the Board is now Priming without wild fluctuations, in fact the voltages don't even move when under load. Now for example I set 1.200v in the Bios and CPUz reports 1.184v with no fluctuations.

Is there a link with pencil Mod steps?!
