Some people told mixing the cards may work,for example if you have gtx 1060 6gb or gtx 1070 8gb.put to 1st slot any of them and try again, if it works then we are good to go,
No, it doesn't work.
Go from WIN10 to WIN7 - work for the moment, but there is a limit in just 5 cards in one rig.
I have 6-8 cards with win 7.
How did you manage to get 8 GPUs working in Windows 7?
Were they 4 AMD and 4 NVIDIA or were they all 8 AMD GPUs?
Back in the Litecoin days there was a reg edit hack which let you use more than 4 GPUs with Windows 7 (4 is the limit with Win7) and you could use up to 6 GPUs. This tool was called something like 6GPUTool or similar. All it was, was some registery hack and nothing more. This worked only for the old Radeon 7xxx/280/290 GPUs.
When Polaris came out in 2016, you needed the newer AMD drivers to get them to work. The new drivers however didn't work with the tool so you had to switch to Windows 10 or Linux.
So I am just wondering if there is a new method of getting more than 4 GPUs to work with Windows 7?
