I´ve recently upgraded my GPU from R7950(Sapphire) to new R9-390 (Gigabyte). I can get into BIOS but once Windows starts to boot it shows black screen and "0_" code in the bottom right corner of the screen. I hear how windows boot (opening windows theme music), but screen shows only "0_" code. Also i´ve read forums here on intel website and many people have similar problem with Intel boards and Radeon 200 and 300 series (and some nVidia card also) so the problem have to be with Intel MBs and not GPU itself. I have latest BIOS (2209) released in 2012 !!!
My request is to update BIOS so it will support those new cards as this MB is still actual and 1150 CPUs are still in production.
My specs:
MB: Intel DP67BG (latest BIOS "2209" from 2012?!?)
CPU: i7-2600K
GPU: Gigabyte R9-390 8GB (non-gaming version clocked to 1000 MHz )
RAM: 4x2GB kingston HyperX 1600MHz
SSD - 74Gb Intel
HDD -WD 1,5Tb
PSU: Forton 700W
