Since we're talking Double Data Rate, that's equivalent to an 800 MHz clock. It's very common for the BIOS/UEFI to default 1600 MT/s RAM to 1333 MT/s. Simply go in there and select the XMP profile for 1600 MT/s. Bic5 March 24, 2013 7:44:59 AM Sakkura said:Your RAM isn't 1600 MHz, it's 1600 MT/s.

Usually you will need to set it in the Bios to run at 1600. Mactronix Can't find your answer ? Ask !
