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.



Well I am not familiar with Gigabyte Boards, but you have a nice processor there, as some else with that Batch# say it has a VID of 1.2000v, so you should get to 3.0GHz with no problems.

It appears you have more than enough Voltage there at 1.375v (you can drop to 1.25v, even stock voltage of 1.20v is possible to reach 3.0GHz), what about increasing the NB Voltage (mine is at 1.60 and I have reach 3.8GHz P95 stable), did you check memory voltage (mine is at 2.1v for 3.6GHz see signature).

FSB should be 334 (to reach 3.0GHz) which means at 1/1 your Memory should be capable of running at 668MHz. (ie Min requirement DDR2 667/PC2 5300). So can your board do FSB 333 (I would think most Boards would be able to do that).

If you think you are constrained by your board, what upgrading the Bios to a different version? Maybe Gigabyte has a fix, if it is a board problem.

What is your Power Supply like?
