like what others have said so i won't take credit for their leg work but last night i manged to get 5 7950 working on a socket 775 mobo, 4gb of ram. windows 2008 server r2 (same as windows 7) working with ati 12.6 drivers. 13.1 will not work!
i had ati 13.1 and had issues detecting 5 or more gpus and decided to install 12.6 and it worked.
my socket 775 mobo has 2 pci-e 16x and 3 pci-e 1x. you need to either short or use dummy plugs on the 2nd pci-e 16x slot.
i'm currently using dummy plugs mod on the 2nd cpi-e slot and have my 5 7950 are mining at 1volt, 1000core, 1600mem doing just over 600 hashs, but these cards can potentially do 670 each but had to undervolt them as i have got other miners running off the same power socket and i am hitting my power limit.
