I have 16GB of Corsair Vengeance (2 2x4GB kits CMZ8GX3M2A1866C9) in a Gigabyte 990FXA-UD3(REV 3.0 with lastest non-beta drivers) running an AMD FX-6300 at stock speeds.
I realised recently that my memory was not runing at 1866mhz. It's only running at 1366mhz. Speccy lists 669.7 as does CPU-Z.
Did some research, realised that I forgot to enable XMP

and then went and enabled it in my bios.
Which is where the problem is. It wont actually do anything. Everything still lists the RAM at 1366mhz after enabling. What do I now?
