Hello. ive got these cards an few months ago.

when i booted up my windows. it gave me an bsod.

it took me 1 - 2 weeks to find out. i had to use an tool to disable ULPS in registery. 

so i used that. and problem whas fixed.

now an while later when i upgraded my drivers. it bsod agian.

and had to run the tool in safe mode.

now every time i upgrade my drivers. i run this tool before rebooting.

why does this happen?? is this an known bug? 

(also they give bad performance in metro 2033 and batman arkham city. and far cry 3)

You don't need a "tool" to disable ULPS. Do a google search >

For CFX its advised to disable ULPS to stop some micro-stutter and other problems during gaming

Search the registry for enableULPS and change any instance from 1 to 0, ignore the other entry I have put a X next to
