Thanks for your replies everyone. I since tested the memory with incremental voltage values at default settings, no success. I ran memtest test #7 for an hour and it passed all tests with no errors. Since my processor is a Q6600 with a FSB of 1066MHz, is that what is limiting my memory speed to 1066MHz ?

Another person had the very same problem as me except they were using OCZ reaper-x memory http://www.ocztechnologyforum.com/fo...ad.php?t=33843
They resolved the issue by increasing voltage to the memory.

Anybody had any luck running this mobo on that OCZ Reaper-X memory (in link above)? How about the OCZ Platinum DDR3 1333MHz memory ? I am looking at these as possible alternatives to just returning the current memory for a replacement (bad idea??)

Any suggestions are appreciated !
