need some help getting my ram to run at 2400

[Grr8xTc]

[ RipjawsZ] F3-19200CL11Q-16GBZHD (4Gx4)
Asus P9X79 DELUXE (Bios v.0906)
CPU: Intel i7-3930K
BFG 1000w PSU
2x raedon 5870 GPUs

I cannot for the life of me get the ram to run at 2400 mhz. It seems to like 2133. I am new to this uefi bios, so there is probably something I am missing or doing wrong. I set the xmp profile for 2400 but it was a no go. Could this be a bios problem? Any help will be greatly appreciated!!!!

Thanks in advance

Have you tried manual settings? Please post pictures with XMP enabled, it should have no problem with that motherboard.

Thank you

What are the symptoms? Booting but unstable? Try boosting the VCCSA voltage a little more to see if that helps.
