Did you try going into your BIOS and enabling DOCP?

Daft question whats DOCP?

It's AMD's version of XMP. You enable XMP profiles with DOCP or EOCP on AMD boards.

ok so i had a look and managed to change my DOCP to profile 2 which said it was 1866Mhz..

If u look at the first picture memory benchmark at the Memory Bus it says 936.4Mhz is that what should change to 1866Mhz when i run the benchmark again..??

thanks for taking the time and sorry about the noobish questions

The frequency shown in software need to be multiplied by two. This is because it's DDR RAM, Double Data Rate, which means that it 'does stuff' twice per clock cycle, instead of once like most other components.

In this case, 936MHz is effectively ~1866MHz. It's usually a few MHz off, this is normal.
