This is a stable system that was memtested for 8hr when first built (0 errors). I ran me test tonight (On a whim) and got errors from the first test on. I had 47 errors at the end of test 3. I run two sticks of 1gb each. I first pulled one (same problem), swapped them (same problem), and moved them to different slots (yep..same problem). The odd part is both sticks give me errors at the same address (00000009b080) in all configurations. I have tested the ram with diffrent volts 2.5-2.75 still getting the errors. I am not overclocking anything. Thank for any help.
