Was wondering if anyone has any suggestions for getting my Q6600 G0 to 3Ghz - can't get it stable above 2.8Ghz atm. Have tried 9 x 333 and 8 x 375 to get past the FSB hole these 650i SLI boards seem to have but no dice.

Voltage Control
DDR2 = +0.40v (2.2v)
NB / HT Link = +0.1
FSB = ?
Southbridge = +0.1
VCC12_DL = +0.1
CPU voltage control = 1.375v

FSB - Memory Clock mode
Linked

FSB Memory ratio (Sync)

CPU host frequency (333Mhz)
Actual memory clock (667Mhz)

If anyone has some other tips, I would greatly appreciate it. I've been tearing my hair out over this - been getting a lot of hard power-off shutdowns too - after inputting settings into the BIOS, the rig will just switch off completely.
