AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz Socket AM3 125W
MSI NF980-G65 AM3 NVIDIA nForce 980a SLI HDMI ATX AMD Motherboard
Ripjaws Series 4GB 240-Pin DDR3 SDRAM 1600 (PC3 12800)

The ram is only running at 1333, how do I go about getting it to run at 1600?

Set it in BIOS. There should be information in the user's manual as well. The memory settings are on the memory. (frequency, timings, voltage)

Thank you
