whats your cpu voltage at. you may need to raise it a tad.I would also try putting your question in the memory section there are plenty of people in there running using that type of mem who should be able to help.

What happens when you're running the test? Does the machine reboot by itself or lock up?

Raising ram voltage won't hurt anything. Any good ram will run good with the voltage at 2.7. Try bumping up the cpu voltage bit by bit.

Also, what temperature is the cpu running? And what heat sink are you using on the cpu?
