I just bought this board and I tried to install the R9 270x and just got 0_ error on the bottom right hand sode of the screen so i tried an older ati card which was a HD6770 and the computer booted just fine into my previous windows installation I had on the HDD. Well I tried to put the R9 back in there to try to get it to work and I am now getting a 1C error on the motherboard. I am really stumped I have tried taking out the ram and putting only one stick, two stick. I even bought two different kinds of ram, one high performance and one low performance (1066) to see and nothing is happening I still the 1C error. I even took the CMOS battery out and put it back in to try and reset the bios and still getting 1c error and bootloop. Any advice?
This definitely seems to be a compatibility issue. Have you tested this video card in a different motherboard?
