Hello! I'm overclocking my XFX 2GB 7850 DD. When I set it to 1090 Mhz and start to test with Heaven or Kombustor everything is fine for the first three minutes but then I get a BSOD: 0xa0000001 atikmdag.sys. This happens regardless of the driver version and I've never gotten temperatures higher than 60 degrees Celsius on this card. I haven't started to overclock the memory yet, it's stock. I've kept the voltage stock as well. I've tried several different overclocking utilities like afterburner and trixx but I still get the same BSOD. Am I just at the limit of my card or is something else happening? Could my power supply be insufficient? Should I be happy with 1085 Mhz or should I try to bump up the voltage maybe? Any input is appreciated, thanks!

Solution
Higher voltage might help. That's how it works, you raise clocks until instability or artifacts set in, then you bump up the voltage and see if you can go further.
