My card is a XFX 6800GT pci-e with softmod qfx4000 I read in wikipedia that the fx4400 is a nv40 br02 (nv45), that is the same as 6800gt/ultra. I found in m*vktech the fx4400 bios: http://www.m*vktech.net/component/o...func,fileinfo/filecatid,1386/parent,category/ (when you click, and the browser opens the url, delete the asterisk) I compare with my own backup and both have the same size (not with dell fx4000). And open with a hex editor I see: that my bios post show: nv45 p211 sku4 VGA BIOS and the fx4400 show: nv45 p214 sku0 VGA BIOS version my bios: Version 5.40.02.36.09 version fx4400 bios: Version 5.40.02.38.10 date my bios: 12/03/04 date fx4400 bios: 01/07/05 I see that both bios are very similar and the fx4400 is newer. I don't prove if this works, for two reasons: 1) fx4400 has 512mb and my card 256mb (with an ultra 512mb card, don't problem) I DON'T KNOW IF IT'S NEEDED. 2) fx4400 has 400mhz/525mhz and my card 350mhz/500mhz (with an ultra card, don't problem, I think) I'm really wormed for the first reason, but I don't know if the bios need this... Somebody know to change the bios with different settings? Thank you.
