I have 16GB (4x4) of corsair vengeance ram and an asus saber tooth 990FX motherboard and the ram is showing as 1333MHZ when it is 1600MHZ memory, can someone explain to me how to change this?
@OP - did you check on page 1-15 of your Mobo Manual that Cosair is the exact one listed in the manual? http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM3+/SABERTOOTH_990FX_R2.0/E8042_SABERTOOTH_990FX_R2.pdf
@Tradesman1 - Yes I didn't realize "the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support" might compensate for that, I was more familiar that "Hyper DIMM support is subject to the physical characteristics of individual CPUs" in that for example if the OP has a Athlon II X2 which may be physically limited (as I mentioned originall) it can't attain to support 1600MHZ like a FX could. (see page 1-21 of the manual link I provided).
The motherboard is automatically picking a speed it thinks is correct. You'll need to get into the BIOS and manually set the RAM timings and voltage so they are correct.

I don't know which part of the bios AI tweaker I change this in?
Depends on your CPU. Check your Mobo Manual, typically the 'speed' of the RAM will throttle back if the CPU isn't capable to address that 'speed' though the Mobo can handle it.
What CPU? In the tweaker section look for a XMP or DOCP or EOCP setting, those are the auto setups AMD uses for DRAM, if you find one of them (think XMP) enable it and select your freq

True, sort of guessing here though, with the Sabertooth (top end mobo) that it would at least have a FX which should run 1600...ah yes, I am assuming and know the meaning of the word (but, then again, have been called much worse )
