Why is my 2400 RAM running in task manager as 1600?

[Kieran_805]

I have a AMD A10 7850K APU, a GIGABYTE F2A68HM-H Motherboard, and 2400MHz Kingston Hyper X Memory (2 sticks of 4 GB). My task manager in Windows 10 Says I am using only 1600 MHz RAM. I Have already enabled both XMP Profiles and both of them have the same result. I want to get 2400MHz speeds out of my ram if it's possible. Any help would be greatly appreciated.

Motherboard supports DDR3 2400(OC)/2133/1866/1600/1333 MHz memory modules. Are you overclocked?

What model memory are you using?
Two of these -> HX324C11SR/8
One of these -> HX324C11SRK2/16

One of these -> HX324C11T3K2/16

Is my CPU Overclocked?... Yes.

I am using two of the HX324C11SR/8

HX324C11SR/8 is a single. XMP settings are for a single, not two of them. Combining multiple singles can cause compatibility problems, such as being unable to operate at rated specifications.

Also, DDR3-2400MHz is for overclocking.

You may want to try manually setting the DRAM frequency clock, DRAM Timings, and DRAM voltage. No guarantees are made when using multiple kits or multiple singles.

Okay. For APU gaming performance, which should give me higher FPS:

One module of this ram at 2400MHz
Or
Two modules of this RAM at 1600MHz?
