Im trying to add 8 gpus on my rig that has only 6 pcie slots, every time I try to add the 8th gpu my system won't boot up, I'm fine with 7th gpu but I can't do 8 gpu. I'm using a 4 in 1 connector its seem to be working with 7 gpu but not 8 gpu.

I'm using a B450-A Pro Max AMD motherboard and AMD Ryzen 3 1200 quad-core processor

Is there some special setting that is required to use up to 8 gpus on the motherboard?

Try just 4 on that connector and nothing else, if it works, well that narrows down the problem.
You goof, this is from May. Before all the mining stuff stopped.
