What do you mean?
No it isn't.
But if you're after a full cover water block then one for a 6870 fits.
Edit
Guide to do what?
DISCLAIMER: Do this at your own risk. This guide is for REFERNCE 5850's only. Doing this on non-reference boards is almost guaranteed to brick your card. DONT DO IT. This may not work for everyone its just a guide of how I did it and how it worked for me. Good luck!
You have a none reference 5850.
What do you think?
Ok I will start this off by saying this is only tested to work on sapphire 5850s but it should work on other reference 5850's
fair enough, how come he performs the flash on a sapphire 5850 then or must it be a different model.
Because like most manufacturers Sapphire made reference 5850 cards initially and then after a while produced their own non-reference variants.
Why do you want to flash the BIOS?

wanted to flash the 5850 bios with the 5870 bios![]()
