Its pretty simple to fix, buy an intel rig. The memory performance for AMD has been terribly behind for over 5 years now. I can run a sandy bridge i3 with 1333 mzh cl9 memory and beat an 8350 with 1866 cl 8 memory in most memory latency benchmarks. Benchmarks aren't that important but an amd rig will always be well behind when it comes to benchies... btw have you actually set up the memory? I'm sure its still running at the default of either 1600 cl 11 or 1333 cl9 if you didn't manually change the settings (either enable DOCP/EOCP/XMP, or manually set 1600 with cl9 settings on stick)
