Help with installing drivers for multi-GPU rig

[shadowhlohavec]

Hello, We have been mining with HD7990 which is dual gpu, so the system recognize it as 2 different gpus, now we managed to get 7950 and 280x and we want to run them together with the 7990. But the problem is - there are already installed drivers for 7990 - Crimson 16.1.1 , we want to get crimson 15.12 for the other cards, after installation of the 15.12 and restart of the system the cards were not recognized in the system, is it necessary to uninstall the 16.1.1 and instal only one version of drivers for all cards? (Win 7, cards are running, 15.12 wasn't working before on 7990-after installation the card wasn't recognized) Thanks

hello shadowhlohavec

i think your problem is not the the cards them selfs but the drivers my friend and the limitations of windows
if i could make a suggestion maybe look into a linux option for your rigg

we have one ready to go take a look at our 1.9 version that could offer the solution you need https://getpimp.org/shop/pimp-classic-v1-9-with-fglrx-drivers/

those are different drivers then the windows one my friend

Oh, thanks, we uninstalled the old drivers and tried to install 15.12 unfortunatelly it's only working on 7990 and 7950,  the 280x might be broken we bought it on ebay saying: no display output... we will do some tests, thanks for offer but windows is good OS for us, linux is too complicated and same performance

Maybe it's silly and you are doing it right but..
You plugged the video cable to the GPU that u want windows to install drivers?

Which video cable do you mean? We don't have monitor we do it via Teamviewer, We have installed drivers for 7950 somehow through device manager and it's working... we also managed to install drivers for old hd270 but after start of the miner blue screen shows up the card was bought as untested so no surprise.... the 280x is not showing in device manager but fans are spinning... was bought with: no display output problem so also no surprise  we will have to do more tests before finally assuming these 2 cards are not working...

I wrote video cable, but that can also mean dummy video plug, u can do whatever u like
Usually winzoz need at least a boot with a GPU as the main one (the one that is providing the video output) to install all drivers correctly.
That could be the reason, since it's very simple to test it you could try
