If you need to stick with Windows (up to 10 including server systems) don't try to connect more than 8 gpu. They will fail, even mobo supports it.

Windows 10 will not support more than 8 GPU's on the same drivers. So you can connect up to 16 as long as its 8 Nvidia, 8 AMD.

Have you enabled 4G encoding in the BIOS? It should be under the boot menu. Also I would try installing 1 card at a time to see if that will fix the issue.

If he didnt have 4G encoding enabled he wouldnt have passed the 4th card.

When I add 8th GTX1060, windows dev. code 43 error reported.
Did any way to solve the issue ?

OS: win8.1 x64

The solution is you need Windows 10, anything under will not run 8 GPUs and will show error 43

The Linux breaks at the install if I have more than 8, by the way, all the cards are the same (model and driver), with the windows server, installing only the CUDA Toolkit, if you add the 9th and 10th.... one card per time, I could reach 12 (my motherboard limit)

I'm having the same problem here, after a lot of research, I discover that the Windows (or the driver) doesn't support more than 8 GPUs with the SAME DRIVER (like 10 GTX 1070), I'm trying with the Windows Server here, if I get any result I will keep you updated

Why not use Linux?

Code 43 is a driver startup error, which typically happens when GPU has a fault. Try swapping existing working GPU with the new card to see if the new card shows up with error 43. There are a number of ways to try to solve this. For many people, linux will not have this problem. Sometimes booting in linux and then back to windows resolves this. Sometimes uninstalling the driver using DDU and re-installing solves this. But at times it can be just a faulty card that needs RMA.

I am giving this input assuming that error 43 is showing up on the new card you are adding. If existing working cards start coming up like this, then this is most likely motherboard/bios related.

Which version of Windows? Windows 10 should handle up to eight GPU's per driver, so eight AMD cards + eight Nvidia cards.

thx, win10 is 8gpu working
but I add 9 gpu , windows 10 crashed when start mining...

did you have to do anything specifically to make it work you would share?
i have one of these boards coming tomorrow, i am also planning an 8 card build and just trying to do my research here hehe
