Need help with GA-Z87X-UD5 TH and GIGABYTE GV-R928XOC-3GD

[flat99]

Hello All,

Trying to install 10.9.2, but so far unsuccessfully.
MB GIGABYTE GA-Z87X-UD5 TH
CPU Intel Core i7-4770K Haswell 3.5GHz
GIGABYTE GV-R928XOC-3GD (Use two display ports with two Apple cinema displays 27")
People write that GIGABYTE GV-R928XOC-3GD is fully compatible and works well. But it seems not for me.
During installation mode Boot Verbose computer stops after inscriptions: {IOBluetothHCIController} {Start} - completed

I took out GIGABYTE GV-R928XOC-3GD and tried to install OS using the built-in MB video card and connect another monitor to DVI port. At this time, the installation was successful. Installed MultiBeast - Mavericks 6.2.1. Then I put back GIGABYTE GV-R928XOC-3GD and now the computer hangs before boot loader. So I tried to install PowerColor Radeon R9 280X and got the same problem.

I would be very grateful for any help!

Thanks!

Last I heard your gfx card is not supported.
