Would bios updates likely increase an Epyc mb processing speed?
Not likely, unless the update exposed more of the cpu's capabilities that software could take advantage of.
Not Epyc but on my Ryzen 9 7950X, by moving to kernel 6.3, I can now remove the last retpoline security hamstring because the kernel now takes advantage of a previously unused cpu capability.
Any retpoline makes the cpu take longer in processing instructions and the removal speeds up the host.
The motherboard, memory and cpu pretty much decide the speed of the host.
Most always have. Or the sockets are in stupid positions so you'd need water cooling.
I thought we were all riser people in here.
you have to consider the intended audience of my post. Tom hasn't had good luck using risers, and my post was assuming that he wouldnt use them
other than that, there's a large number of AM5 boards which only have 2 pcie slots, total. some have 3, few have 4. none have 5 or more as fas as i'm aware.

I've never had a problem with mine, only getting decent 12V power to the cards. If they don't have solid power, they're unreliable.

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.

Peter,
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.
The other thing I ran into is lane limits. You can buy adaptors to convert m2 slots into cable risers. I found I could not get my Ryzen boinc systems to boot if I had more than 4-5 GPU's plugged in.
I also spent a lot of time experimenting with high slot count Ryzen motherboards before I threw up my hands. 4-6 slots. The one MB I have virtually no experience with is the Msi x570 godlike. Too expensive. It has 4 full length slots but does not have 16x on all slots if all 4 slots are plugged in.
I ended up in the fewer, more powerful GPU's end of the game for Ryzen/Intel-based systems.

What on earth would limit it to 1-2GPUs?

Simply the fact that the new motherboards only come with one, maybe two X16 wide PCIE slots.

Never used risers. Always installed gpus natively. Too much headache with risers and special mining chassis to use them.

Makes it kinda difficult to put 6 GPUs in a machine.
And why a special chassis? I just sit the GPUs on their side next to the machine.
