Hey guys I'm trying to build a new computer for a friend. I hooked him up with a Gigabyte z68x-UD4-B3 running an i5 2500k. We've got two DDR3 sticks in, but whenever we run it in dual channel mode the system crashes as soon as we run prime95. It's not a heating issue because if we run 1 stick the machine works fine. I tried running in different dual channels 2,4, and it still didn't work.
