Athlon 64 4000+ San Diego\r\nAsus A8R-MVP\r\n4 512mb Kingston HyperX ddr400\r\neVGA 7600gt\r\nOCZ 600wt GameXStream\r\n\r\nJust got a new rig, but it wont seem to post with more than 1 dimm. If I use just 1 stick, it posts fine, but 512mb is kinda wimpy, especially since ive got 3 more 512 sticks just waiting to be used. All four sticks are fine, board can boot with all of them if I use them one at a time, but when I try to use 2 or more, it doesn't even post. I figure it isn't a power problem, since the PSU is overkill, and isn't and installation problem, since it will post. Any help would be much appreciated.
