I just installed a wintec ampo 2x1gb pc3200 kit in my 9nda3+ and I can't seem to get it to pass the first test in memtest at dd400. I'm running an opteron 165 dual core. With both sticks in the sticks fail at the first test. If I individually test each they pass memtest. Doesn't matter which slot they are in. Is the cpu limiting me or is it the motherboard?
