Z503's died...Purchased Oct 20, 2005

Well, my comp has been acting strangely, had to clock it way down, constant reboots when folding, etc. It turns out my Ballistix PC4000 at fault. I plugged my OCZ PC4000 (2x512) back in and Comp is happy again.
Damn Ballistix, gotta wait for an RMA# now. Any guess as to how long?

welcome to the party. I've had two sets die since July. These are being discontinued for those that didn't know it already. Personally, I think they shoulda been discontinued months ago.
