Then why do you suspect the ram? Especially with 12 disks, another likely candidate could be an overloaded power supply. While there may be problems showing up in RAM, it may only be happening under the combined load of disks, cpu and memory activity that brings the system into marginal power conditions. Sometimes it may be just one rail that is out of bounds, and other devices are unaffected. If memtest didn't find any problems without the disk and cpu load, that tends to support this hypothesis. So, the memory may not be "bad" per se, though it's still not ECC and therefore not "good" either :-) Perhaps you can still find a good use for it elsewhere. > I removed 2 of the 3 sticks of RAM, ran a backup, and had no > errors.

Switching to ECC is a good thing.. but be prepared for possible continued issues (with different detection thaks to ecc) if the root cause is the psu. In fact, ECC memory may draw marginally more power and maybe make the problem worse (the new cpu and motherboard could go either way, depending on your choices). -- Dan.
