About the PCIE clock. I think I have either 100 or 101 set in BIOS.
Based on some comments I think I should increase to 110 or more. I ran small-FFT at 2.92Ghz for 2 hours, with <50C. However, playing BF2 after about an hour at 2.8Ghz (notice lower fsb and mem clocks), the game gets choppy for no apparent reason, and/or I get blue screen.

First impression was that the default clocks on video card are too agressive or poor cooling, but it barely gets over 60C.

Can somebody please confirm that PCIE fixes such issues, and if so what value to set?
