I wanted to mention the importance of cpuPLL voltage. It is definately important to increase this votlage when going over 400mhz FSB with a quad. There is no specifics...each cpu will differ. For example, my B3 quad doesn't care for it...increase too much and stability was quickly lost. My G0, tho, was not stabe for 48hr prime without 1.8v...1.7v...33hrs...1.75v...38.5hrs...
Also of note is that my B3 did not need any FSB or PLL voltage change when FSB was increased(or it had negative effects), while my G0 ABSOLUTELY REQUIRED more vFSB and cpuPLL. b3 was happy with 1.2vFSB, 1.5v PLL, as a comparison. Unfortunately the power draw of the B3 was too high for this board, however I can go all the way up to 1.65v on my G0 without seeing the "prime95/system process" issue when loaded, further pressing the idea that the "EPU", by means of cpu power consumption, is what is affecting the "Prime95 issue".
