I am using a GIGABYTE GA-EX58-UD4P LGA 1366 Motherboard and CORSAIR DOMINATOR 6GB (3 x 2GB) TR3X6G1600C8D RAM.
I can only boot my system with 1 stick in ddr3 slot 1 of my motherboard. When I try to add another stick in slot 3 or slot 5, the system won't POST and the LED lights on my motherboard turn red. Right when I turn it on, the CPU fan would spin for a few seconds then the system would shut itself off and turn back on in a few seconds. I tried swapping out the ram sticks with all 3 sticks in slot 1 and it worked. So I'm guessing it's the motherboard or the BIOS settings. I tried messing around with the default bios settings for RAM frequencies but it still would not boot with optimized settings with more than 1 stick of ram. Any help would be appreciated...

I set the voltage to 1.65 and the timings to 8 8 8 24 and still won't boot with 2 or 3 ram sticks. I can boot with one stick at a time ( tried all three different sticks in slot one). Do you think the RAM slots on the motherboard are defective?
Please try F13 revision of Bios. F14 sucks. Try one stick of RAM at the time to have a succesful boot. Memtest86+ or Prime95 for half an hour, add more sticks. If you use Memtest try a bootable CD with it to avoid windows environment. Reply as soon as possible. Good luck.
Just to clarify something, F14 revision made my network card (onboard) ... "invisible". Not detected by BIOS or windows anymore. Revert to good ol` F13 everything come back... Exchanged a couple of `mails with Gigabyte tech support they asked me to use F13 as per instructions F14 is still beta. Their response below:
"Answer : Hi,
There are two ways to check the problem.
One is to update bios to the latest beta F14m, however, it may not work as solution and fail as F14k.
The F14k and F14m are beta bioses, not a formal release, so that there may be some unknown issue to be checked.
The other way is return to F13 after testing F14m fail or not test it at all.
It is suggested to keep F13 until F14 formally released."
