Aright get into your BIOS, go to GENIE BIOS, then DRAM configuration...make sure everything is at AUTO
Change the COMMAND PER CLOCK to 2T or T2 (it can be displayed as either depending on the mobos and whatnot) , save changes, then try slots 1 & 3
EDIT: Also in the genie BIOS screen make sure the FSB Bus frequency is at 200 and the CPU/FSB Frequency Ratio is set to 1:1, or if you see options like 3/3, 4/4 or whatever they all mean 1:1
DOUBLE EDIT: Make sure the Jp17 jumper is in default position on pins 1 & 2.
Also in the BIOS under genie BIOS make the DRAM Voltage at 2.8v
