Are you checking it with GPUZ ? You have to have the latest version or it reads wrong. Is the screen a blue screen crash or an orange screen when pushed. I had both problems too. The newest GPUZ read it right and the orange screen crash was only with BF3 so I'm assuming you are getting the BSOD ? Changing cards can be tricky I'd do some more work before returning it. Use the provided driver and once you get it squared away, then try updating it. I had a week of screwing things before I got all the ticks out of it. Good Luck Rubber Duck !
