I switched the 1333mhz ram that came with my G74 with 1600mhz RAM, but CPU-Z still shows it running at 1333mhz. Is there a way to adjust the speed manually? My G74SX is the AH71 model with 2670qm. It came with 16Gb of RAM which I replaced with Samsung Green DDR3 4x4Gb that I got from Fry's. Is it incompatible to run at 1600mhz in G74? Should I return it and get different type of RAM? Can someone help me please?
