I recently had part of a 32 gig DIMM go bad on a 128 gig system. One of the larger VMs was spontaneously rebooting for no apparent reason. I was able to find the addresses with MemTest86 and map out 512 megs of the affected DIMM with the Linux kernel memmap option.
So you can still use the hardware via software fix?
Correct! Basically, I excluded the bad range so Linux doesn't touch it. It's been stable for weeks now. I should send the DIMM back under warranty.
Don't send it back. Since they can't easily replace it with new hardware, they will probably refund you the price of purchase. Which is normally a very good deal, but obviously not in these circumstances. I've seen it happen with GPUs as well.
