I was just wondering realy quick. If i put 3 unbuffered blocks of pc2100 ddr ram in my abit kg7 (dimms4-2), will it cause any problems? I have it now, and it seems to work fine, but I can't seem to run any games that use direct3d. I reintsalled video drivers and dx and figured it might be my motherboard. Anyone have any idea if that 3rd block of ram could be affecting something with my video card? Do I have to change any bios settings to get 3 unbuffered blocks to work right? anyone?
