I have looked in my BIOS settings and cannot find where I have gone wrong. There is only one place to change the memory voltage, and I have it set to 1333 with 9-9-9-24.
My motherboard looks like it was doing MCH Strapping on 'auto' setting, could that have been to blame? I set it to match DRAM frequency now. I am at a loss.
Thank you for your quick responses.
