Hi all,
I just got Sapphire Dual-X R9 280X OC 3GB (card BIOS 015.041) and I'm having some problems. Basically I get random black screen flashes in 2D Windows apps like desktop or 3D games. The PC doesn't crash, it's just a 1-2 seconds black screen flash and when I play games I can hear sound as normal when it happens. Also from time to time when I boot Windows 8.1 64-bit I get black screen with cursor instead of normal login screen and then when I hit ESC normal login screen appears.
My PC specs are.
i2500k - not overclocked now
Asrock P67 PRO3 REV 3.0 latest BIOS
G-Skill 8GBXL Ripjaws X 1600MHz
Cooler Master RS550-ACAAE3-UK GX-Series 550W Power Supply

GPU to monitor connected via DVI
I know that for 280x 750W PSU is recommended, but I think my PSU should handle it.
I tried Omega (14.12) and 14.11.2 Beta drivers, I tried Legacy and UEFI BIOS mode - same thing happens, black screen flashes
PC was working as it should with my old 6950 card. The new 280x is factory OCed, I haven't tried to OC it more.
The card requires 6-pin 75W and 8-pin 150W PSU connectors. I used one 6-pin and provided with GPU molex adapters for the 8-pin. The PSU has 2 x 6+2pin PCI-E Power connectors.
Shall I try to use 6+2pin for the 8-pin 150W connector instead of molex adapter? It confuses me slightly...Is 6+2 pin 8-pin 150Watts? I know that 6-pin in 75W.
At the moment I don't suspect PSU as "black screen flashes" in 2D too when GPU should not need much power. I might be wrong though. That's why I'm asking about the 6+2 pin...
If I do try this and it doesn't help, have you got any suggestions what else I can try?
I have created support tickets with Sapphire, but it doesn't go anywhere...Their support is not good at all...so I'm hoping someone here will help me.
Thanks.
