1) Motherboard won't post with 8GB of RAM (4 x 2GB Crucial Ballistix 6400). Trying the sticks individually works fine in any of the RAM slots, installing any two sticks in dual channel mode works fine and installing 3 sticks works fine. Once I put in the 4th module, it won't post at all. Maybe this motherboard doesn't support 4 sticks of such a high voltage RAM?
2) BIOS keeps saying unsupported CPU. I have a Q9450 and installed the latest BIOS (0405) which states this CPU is supported? Although according to the BIOS, the CPU is operating at 2.66GHz so maybe the message is false? Before I updated the BIOS, the CPU was pushed down to ~2.2 GHz.
Any ideas would appreciated as I am getting frustrated.
Should be an option for dram voltage. Under advance. Check your manual for specifics.
Set voltage at .1 higher the manufacturer specs and possibly 2.1-2.2. Lowest stable. My Asus board defaults ram at 1.5 on auto. My ram needs 1.8 so I set it there. I only have 2g so I dont need the xtra volts. Set your timings if they arent right also.
Thanks for all your help roadrunner. It turned out to be one bad DRAM stick. Swapped and all is well. Although I can't get the RAM to run at the spec'd 4,4,4,12 timings, but I'm happy with the 5,5,5,12.
