I never noticed there was a list of "recommended" memory, but your comment made me look and I found one. PQI is not on the list :( But... we had a similar system with the same mobo and ram stick - only one 512M, not 2x1G like these - that was running for years with nary a hiccup until the disks died. The one we are having problems with was its upgrade/replacement. Maybe this is a problem though. thanks Sam
