This is info from speccy
16,0GB Dual-Channel DDR3 @ 665MHz (9-9-9-24)

MB supp
2 x DIMM, Max. 16GB, DDR3 1600/1333/1066 MHz Non-ECC, Un-buffered Memory

and what i bought (ram)
Kingston 16gb kit ddr3 1600mhz cl10 hyperX blu black series

so what am i missing?
 


665 x 2 = 1330 so it's running at it's 1333mhz preset. Probably an xmp profile that is either wrong or set to auto. If you change that you should get your 1600mhz.
