How many memory slots on the motherboard? 4?

Did you put the RAM right next to each other? If so, if the slots were numbered 0, 1, 2, 3, put the RAM in slots 0, and 2.

Otherwise I suspect some strange dual-channel setting in the BIOS.

------------------------------ GA-X38-DS4 (BIOS F3)||E8400 C2D (3.6GHz)||6Gb Crucial Ballistix DDR2-800 4-4-4-12||320Gb WD Caviar||2x 750Gb WD Caviar||Cooler Master Real Power Pro 750W||2x HD4870 512Mb(Crossfire)||HT Omega Striker 7.1

I put memory in the yellow slots - DDR2

My MB doesn't recognize them as 1Gb but only 512 each, so i have only 1 gb now, instead of 2Gb :(

TIA.

Are the modules single sided (8 chips) or dual sided (16 chips)? As per the QVL, that motherboard requires dual sided 1 GB modules.
