I've also have the K7 with the F3 Bios installed and i'm using the Corsair CMK16GX4M2B3000C15 ver 5.30 which is on the support List.
But getting the memory to work with 1499 MHz (DDR4-2933) won't allways work...
I've activated the XMP Profile which somehow works for one boot sometimes, but after that when i reboot or cold-boot the System the memory Speed goes back to 1066MHz (CPU-Z)...
Also a menupoint in the bios isn't translated (german language active but one setting is in italic?) and the RGB Color changes from cycle to full red - like it's forgettting it. Even after booting into windows it sill is in the default red lightning mode
Saw in this thread that people have their fingers on beta-bioses - where do i get them?
:Edit: Nevermind - found it
