If this card runs any slower it will be going backwards... wait a minute, it darn well is I've tried this again using the 512MB ROM that doesn't work in OS X. Ubuntu runs just fine, although just using fb mode due to the lack of 3D drivers for Nvidia in PPC linux Edit: Here is the Debug Info from nvclock with the 7800 using the 256MB ROM.

root@PowerMac-ubuntu:~#This time nvclock reports the full 512MB, but still says 128 bit DDR  I will have to look at the source code to see if I can figure out were nvclock reads these values from, It should read 256bit. Also I must see if there is a newer version of nvclock that can correctly identify the card as a Nvidia 7800 GS. I also have a ATI 9000 Pro which I rescued from a trash can. I've cleaned it up and lubed the fan with a little silicon grease. It runs sweat as a nut in my windows PC, but after flashing with the Mac ROM I just get a corrupt screen in OS X. This is real annoying as PPC linux has 3D support for this card. Any advice on modding this card for PPC use would be appreciated. |
