Hey guys so I have
16GB 2x8gb sticks of G.SKILL RIPJAWS 1600mhz installed in my asus p8z77-v-deluxe,

now in the bios it shows its running at 1600mhz

however in CPUZ it shows 667mhz ????

As well as in the asus AI utility it shows 667mhz... x2 = 1333mhz :(

i tried bumping up the voltage to 1.65v on the dram ... no luck :(

any suggestions ?

here are some screenshots asus utility

You need to enable XMP in BIOS. You may also need to set the speed to DDR3 1600 under memory options in BIOS. Hopefully you have 1.5v memory and if so make sure you leave it at that.
 
If it shows as 1600MHz in the BIOS then I would think it's running at 1600MHz.

What does MEMTEST say? ( www.memtest.org )
(You should run Memtest to test your RAM anyway OR you can also run the Windows 7 tool, Google or run HELP to figure that out. Start the memory diagnostic in Win7 and reboot).

Other:
- update BIOS if needed
- XMP profile, as mentioned (verify both frequency AND proper timings)
