Thanks. I ran memtest86 off a knoppix5.1 cd for about 12 hours on all four sticks. It made 6 passes and did not return any errors. Perhaps I should have left it run longer?
I don't trust memtest86 for 64-bit mode kernels... I've seen examples of it running just fine for days, when the kernel barfs after an hours usage. It is just 2 machines, so not a large sample from my side.
Clocking down the memory helped in one case.
