As you may know, Seagate had various troubles with the .11 firmware. I have some of the ST31500341AS CC1H and mine are new enough that they are supposed to be ok. > Therefore, I am inclined to think the motherboard/memory (a "TYAN > Thunder K8WE S2895") would be at fault here, I have been told that Tyan does a good job with memory, although even assuming that's true it could still be a memory problem. My Tyan board has a memory scrubbing feature that can be turned on in firmware, but I've never tried it. Also, you could try rotating the SIMMs and see if anything changes.home | help
