I just purchased this set of ram. I want to run them at at least 1600. What do i have to do to get them running at that speed. My BIOS automatically lowers them to 1333.

There's an info thread for helping AMD users get their DRAM to 1600 here:

I'd try starting at 1600 with the stock timings of the set, 9-10-9-28, 1.5 and 2N or 2T. This may or may not work...the CPU's are rated up to 1333 with 2 sticks (this was tested with 4GB sticks) and the earliest Phenom I generally recommend to try running 1600 is the 965 Rev C3

See AMD's chart here: http://support.amd.com/us/kbarticles...encyguide.aspx

Also w/ 8GB sticks may need additional DRAM and CPU/NB voltage from what is in the info thread due to the higher density sticks
