FX5600xt mod ......

Im looking for a BIOS editer for fx5600xt cards and a way to voltmod them
Is thare a way to flash a XT to a regular 5600 or better yet a Ultra ?? My card runs 400 core and 675 mem fine but i Ultra runs at 800 mem i think.. Assuming I flashed my card to a Ultra and found a way to downclock the mem to 675 in the bios whould it unlock any goodies like shaders ? I found THIS site and i tryed the 5600 bioses thare but i cant find a BIOS editer to change the core and mem speeds in the bios ....Any one have any luck moding these things ??

 

I thought I had read somewhere that the XT cards could not be flashed to Ultra status. I know this is the case with the 5900XT, maybe it's different for the 5600. With the 5900 it has to do with the different memory modules. I'll look around to see iffin I cain't find that article.

 

I managed to make a good rom but when i try to flash it i get a "file needs to have .rom extintion" error.... the files name is 5600.rom ........
