PC3-10666 means that there is a peak transfer rate of 10,666 MB/s, and it is 1333MHz.
You should set your RAM timings like this:
CL - 9
tRCD - 9
tRP - 9
tRAS - 20
Then you should up your speed to 1333MHz in your BIOS.
I already tried this and it failed on me...
When I type in my serial number for RAM it tells me this is optimized for intel,,, i have amd...would this make a difference?
