Hello,
I'm struggling with 6*570 on H81 Pro Btc r2.0. First thing I want to ask, what driver to use for Win7? I know that everything is working on Win10, but I hate it!
5 GPU is working OK with 17.4.4 and this patch, but as soon I plug 6th card, Windows start to load, and then it hangs. Without this patch and with 17.4.4 4 cards work, and 2 are with error.
BR...
Yes, this board is buggy. Wont buy it again. And it seems the quality differs from board to board. Anyway. I reinstall Win 10 completly (rest all data) plug everything in. Boot it and than never touched it again.
You need to set the PCIE to generation 1.
