Does AMD Overdrive or Gigabyte EasyTune 6 actually work for anyone else out there with a 990FXA-UD3? Neither one will actually change multipliers for me and they both read some frequencies and voltages wrong. I have to make all changes in the BIOS.

@blossa: At least on my UD3 with an 8120, F4 wouldn't POST with my DDR3-2000 memory set above 1600. On F5B I could do 2000 stable. Perhaps your board is in a similar position where a future BIOS update alone will help.
