Accepted Answer

Hello all
THE BIOS FLASHBACK port in the datasheet is WRONG. The poert is marked green.

Answer

The board works together with the 6800K.
Also with the RAM [HyperX Fury Black (4x, 8GB, DDR4-2666, DIMM 288)](https://www.digitec.ch/de/s1/product/hyperx-fury-black-4x-8gb-ddr4-2666-dimm-288-arbeitsspeicher-3522196?sector=1&lang=de) (HyperX Fury Black if the link is dead).
A current list (19.07.2016) of supported RAM can be found here: http://dlcdnet.asus.com/pub/ASUS/mb/LGA2011/X99-A/X99_Series_DRAM_QVL_for_i7-69xx_68xx_processors.pdf

The file on the stick "must" be called X99A.CAP.
Instructions here: http://event.asus.com/2012/mb/USB_BIOS_Flashback_GUIDE/

Procedure to flash correctly:
* The board must be switched off.
* Press the flashback button until it lights up blue.
* Insert the USB stick with the update file with the name X99A.CAP.
* Press the flashback button for 3 seconds until it flashes.
* Wait until it stops flashing (flashing process completed).
If the LED stops flashing after a few seconds, something is wrong with the stick (formatting, file).

Answer

After that I had to use an old GRAKA to be able to install BIOS UPDATE cleanly.
