I just put together a build using a Gigabyte EX58-UD3R board, i7 920, and 3x1GB of Crucial DDR3 1066 memory. I have previously used the exact same memory in another build with the EX58-UD5 motherboard with zero issues. However, with the UD3R, the BIOS is only showing 2GB of RAM available. The M.I.T. settings show all three slots populated, but I only get 2GB of RAM available. The three white slots are populated as indicated in the manual and I have flashed the BIOS to F3 as well. I've reset the BIOS using the jumper and the battery, but still no go. At this point I am wondering if there is an incompatibility with the RAM since I have swapped the sticks back and forth between slots with no change. I've also tried booting with a single stick in the first slot, but the board refuses to post that way. This is the memory:

Another oddity I have noticed is that if I enable AHCI mode in the SATA controller, the computer reboots right after posting. Default IDE mode works fine.
I've ordered some G.skill memory that others have used with this same board in hopes that it is an incompatibility issue, but I was wondering if anyone else has run into a problem like this. If the new memory does not work, then I guess I will RMA the motherboard...
Thanks...
