I have Corsair 4GB module, which is working on 1333MHz, but it's working on 1066 only.
I got this module: Corsair Memory Attachment 224647
When I set ram freq. in BIOS on 1333MHz, pc is not starting. I got: Overclocking error.
It's set on auto, and it's working on 1066MHz.
Why I got this ? The mobo can handle up to 1333(1600 OC), and the module is 1333MHz.
