The 5900 to 5950 ultra mod is a hot topic and lots of people are flashing their cards and succesfully turned a 5900nu into a gainward or leadtek 5950ultra "128mb"

Nevertheless I give a word of caution before attempting this.

Check if your gpu can handle at least 450mhz stable.

Check that your memory can run at least at 900mhz without artifacts

If your card can handle 450/900 then you can attemp to flash it into a 5950 ultra. The higher voltage make it reach ultra speeds (or higher) with no problem.

Make a bios backup just in case.

If for any reason the card is not stable at ultra speeds just "underclock" it a little until its stable.

I did my Gainward 5900 Ultra 256. It is now a 5950 Ultra 256. And cooler temps again. Defaults core/mem is 475/945 now temps of 40 C no load and never goes above 49 with load. No probs..... no artifacts. At the link there is loads of info, and links to all the bios.

Uhh, all this is pretty much covered in the thread about this subject, why start a new thread just for this?
