Brand new build. Clean installed Windows 7. Updated the BIOS, drivers, and did all the Windows updates. When I go into the BIOS it says my ram is running at 1333 MHz instead of 2400 MHz. I have a AMD A10-6800k CPU, ASUS A88X-Pro mobo, and ADATA XPG V2 8GB (2 x 4GB) 2400 memory. How do I fix this? Thank you for any help you can give me.
