***STAY AWAY FROM GEIL***
This board has nothing but problems with it. I purchased two sticks of GEIL Ultra Platinum PC3500 and the board, when set to SPD detection WILL NOT boot. I had to manually set the settings using a borrowed stick of lower speed DDR, just so I could get to the BIOS. Not only that, I upgraded to the F6 BIOS and my board would not boot without doing an autorecovery of my reconfigured F5 BIOS that I had backed up. In addition, only one of the two 256MB sticks that I bought would work in the board. The second stick just beeps as if the board can't see it. I can't say whether the stick is bad or if this board is so picky about the RAM that it just can't see it.
I recommend Kingston HyperX pc3500. This memory has been tested by Gigabyte RMA, I should know, I had the displeasure of them handling my board when they thought it was bad because it wouldn't boot with the GEIL Memory. That's what I would go with.
