Hi, I have an ASUS Maximus Hero VI Motherboard with an Intel i5 4670k processor. I just upgraded my RAM to 16gb (2x8) corsair vengeance pro series 2400MHz. I go into the BIOS to overclock the RAM and set the frequency to 2400 instead of leaving it at auto. I restart the computer and it brings up a screen that says overclock failed and lists my ram frequency at only 1333MHz. The only way I can get my computer to boot is setting the frequency back to auto. Help?
