Weird. Micron seems still to be having a bit of a prob. G.Skill as well... Eclipse conspiracy? I just tried a pair of G.Skill (ddr 400 the red heatspreaders) and the Biostar didn't detect... I did buy it used... but I will try with 2 different modules later tonight. I'm not liking the Intel side oF OCing, DDR 2. With AMD it's sooo easy. Hopefully things will change a bit with future hardware.
