Both memory sticks from Kingston failed. I tested them one at a time. I did drop the CRIMM a few inches from my hand to the table. And I've been very busy fooling with hard drives and drive cables and playing with 2 different, really cheap network cards. It's possible the Samsung memory is bad, I suppose. But I tend to wonder if I fried something on the motherboard with static or was otherwise klutzy. I'll try a few other memory test suites to see what they say. Bob Gerry Tool wrote: > Robert L.
