I have an annoying cold boot issue.
When using DRAM divider 2.50 computer will cycle ON/OFF/ON/OFF and I'll have to Clear CMOS or hold INSERT while powering on again.
Don't have this cold boot problem with 2.40 divider.

The other issue is when I change FSB, whatever value, higher or lower, computer will cycle OFF/ON and then quickly turn off.
Started happening after I got a Corsair 650TX PSU.

Current settings: E6750 @8.0x420 1.35V, DRAM @1008MHz 5-5-5-15 2T 2.00V
Raising voltages doesn't change anything.

Seems like a BIOS issue to me, the cycle ON/OFF things usually happens, but with this particular PSU it causes the computer to completely shut down requiring a Clear CMOS or to hold INSERT while powering on again.

Using F7 BIOS.
Using F8C BIOS made cold boot problem appear with any RAM divider different from "AUTO"

PSU works fine in another system. I don't have other Gigabyte Intel/DDR2 board to test.
