Tried the guide above with a AsRock BTC Pro H81 board and 6x Radeon 270 cards (not 270x). It doesn't work. When I select any of the three .inf files in the directory and then 7800 series (or any other series), it just says "The driver selected for this device does not support this version of Windows".
I have also tried modded drivers for v13.1 and also 13.12, however both never work in win7 OR win8.1 (I've been at this for a while now). This is because the modded files are not digitally signed. Disabling driver signing doesn't work after a restart or two even if you force the system to always operate in 'test mode'. Eventually the 6 GPU will show up all with yellow ! marks next to them because windows realises the drivers are not signed. Yes I have tried all 3-4 methods of disabling driver signing on all these OS. Signing the drivers using DSEO is supposed to be the #1 option in this situation, but in this case it is not practical because there are hundreds of files in the AMD driver package and it can only do one at a time via providing a direct link to the file... arduous.
