Yes, it is a Gigabyte mobo. 990FXA-D3 to be precise, sorry about not including it earlier.
Its an oldy!!!
So you said you cleared cmos, you didnt happen to leave the jumper in the clear position did you? (Gotta ask, Ive done it a few times lol)
If not, try this.
One stick of ram 1st slot.
Power off switch PSU
Put clear cmos jump in clear position
Remove the battery.
Let it sit for 1/2 hour to a full hour.
Install battery, remove cmos jumper and try a post with just the one stick.
Typically on a dual bios, if the first fails to post, the second bios will post with the stock bios. This bios cannot be flashed. So it may be possible you are running a cpu that was released after the factory bios.
That is all for now.
