I have the MSI P67A-G43 (B3) motherboard and I bought ADATA Gaming Series 8Gig (1600mhz) ram along with it. I know the two are compatible but for some reason the ram still runs at 1333mhz instead of 1600mhz. I went into the bios and instead of "auto" I switched it to DDR3 - 1600 but still it runs at "667mhz". I even tried turning on XMP but still getting the same result when using auto and DDR3 - 1600. How can I get my motherboard to recognize the ram at 1600mhz instead of 1333mhz?
