I had my e8400 on a P5K Premium for the last 6 months at 500x8 at the following settings.
CPU 1.352v
CPU PLL 1.5v
CPU GTL 0.63%
NB GTL 0.61%
NB 1.4v
CPU VTT 1.1v
Memory 1.9v @1000mhz 5-5-5-12 2T
I received a nice Gigabyte x48-DQ6 in hopes of pushing for 525x8 for 4.2ghz for a better 24/7 overclock than the previous board. I've tried just about everything to get this board stable and can barely get it stable above 500fsb in the first place.
I've dropped the multiplier to 6x and found that 500fsb is partially stable with the following settings:
FSB Overvolt +0.2v (1.3v)
MCH Overvolt +0.225 (1.475v)
CPU voltage 1.375v + load line = ~1.35 in windows
CPU Clock Skew 50ps
Still won't be 100% stable, only good for about 15 minutes in Orthos.
I can't figure out why this board isn't even performing on par with my P5K premium, I figured this could probably out do that board. Could anybody with previous experience with the board lend a hand? I've included some BIOS shots.
