Yep, I'd exchange the DRAM for a 1866/9 set, they never should have mixed a 2133 set (even with the loose CL11) with a 6350, should be able to run 1866 though
One thing though... how come my Ram same as above, works with my build?
Mobo: asrock 970 extreme4
Cpu: amd FX-8320
Gpu: Gigabyte radeon 7870
Ram: G.skill Ripjaws 8gb 2133Mhz (2x4gb).
Any thoughts about that, can't find any threads about what ram frequency my motherboard can handle so...?
