Are you meaning you need a slot per GPU? That's incorrect. I use 4 way risers. That works fine on anything but Folding@Home which needs a lot of PCI-E bandwidth. For that I limit it to 3 per slot.
I, and many others, contribute to projects that have far higher PCIe bandwidth requirements. GPUGRID ACEMD3 starts to bottleneck below PCIe 3.0 x8.
You have demonstrated you are a better pc technician than I am.
I spent hundreds of hours trying to get cable riser expansion (1 to 4, 1 to 8) cards to work reliably on my Boinc systems. I could get some up. But they were "brittle" usually requiring I check them daily to see if they had crashed. And they did crash.
I used to have problems, but I found they were never due to the risers. Just getting stable power to the GPUs. Now they work just as well plugged straight in as on risers.
It's best to keep different models on different computers, especially if there isn't a driver which runs both.
I run all the GPUs off a very thick 12V cable running right round the shelving unit they're on. This has 1 kW PSUs attached at various points, which allow me to vary the voltage. So I can get a decent 12.6V (max of PCI-E spec) to every card.

I'm not on that as I have no overpriced Nvidias, I can't think of another project which has a high bandwidth.

It's got at least 5 full length pcie 4 gen slots. It's cheap and it's used.
It handles gen1 and gen2 cpus.

looks like it has six x16 slots, not five. and the x8 slot is open ended so you could put a GPU there too if you wish.
just keep in mind you'll have to use risers in all but the bottom two or three slots since the ram slots and CPU are in the way for the upper slots. the somewhat odd form factor is another consideration. looks pretty close to E-ATX/EEB though you might need to customize some mounting holes.
The target would be a mining frame. If I bought it, it might be another GPU and whatever system.
Problem is I can get a dual CPU mb for about $100 more which would give me more stuff to experiment with.
It must be time to start up my testbed again. I am getting itchy fingers.

Does this look like a good choice for an Epyc mb?
