Good FM2 + board with minor flaws in UEFI

I have the board with an A10 7850K in use. The Board is doing what it should but one thing is then the UEFI but then ugly. I've brought with 2400er RAM (GSKILL F3-2400C11D) which works very well in the Board only you have to manually specify the next frequency and timings. Automatic selects the UEFI wrong timing and the computer does not start up (The UEFI reports the RAM error and prompts the user for help on).
But why the UEFI wrong timing is selected me not seen it recognizes the RAM and also shows for the RAM and the frequency corresponding to correct timing (is a corresponding display in which you can display all the values ​​for the RAM at different frequencies ). But as I said, in auto mode the wrong timings are used at 2400 MHz simply. This is unpleasant, but bearable. They can indeed manually specify then it works.
Otherwise a nice, well-thought-board.
