Hello. I have one of the Rackable System Servers and I have recently upgraded its RAM from 2 GB to 6 GB. It shows "installed 10GB usable 6GB" RAM but, after a few unexpected restarts, the value dropped down to 5.94GB usable. I have also noticed quite high temperatures in processor areas, next to the ram sticks. Is is possible for a RAM stick to actually lose some memory (maybe because of overheating)? What could be other cause for that? The 0.6 GB(that was there) is shown as BIOS reserved but it was not before. Thanks.
