No i'm not having problems with CAS 7 @ 1600MHz but i would like to try 1800+MHz and my Memory will not do it with CAS 7

No XMP Profile

What ever I set the CAS to in BIOS it will always revert's back to CAS 7

Hmmm, well this is a shot in the dark. Perhaps under Advanced Memory Settings one of the settings there is forcing a set cas rating based on SPD:
Performance Enhance (SPD)............. [Turbo] Maybe try setting to something else, like disabled or manual.
DRAM Timing Selectable (SPD)............ [Expert] Same as above.

I don't own that board so I really don't know, but it's worth a shot at least.

When you change the setting, exit, boot into Windows and it's different, does it change to 7 in the BIOS as well, or just in Windows?
