Memory not running at full speed

It is running at 1300MHz constantly and it is suppose to run at 1600MHz, any reason why? Specs at bottom.

Are you overclocking your build? If not, 1333Mhz is the fastest your RAM is going to go....that's officially what the AM3 boards support.

According to the specs it says it supports 1600 without overclocking.

I think you will find that 1600 speed is for the new Bulldozer CPU's when they come out. For AM3 which your x6 is, it is 1333. This might help explain it,


If you have the memory speed set on Auto in the bios then it will default to what the memory controller supports. To get it to 1600 you'll have to set it manually.
