Well, if you think about it . . . that is to be expected with the limited amount of lanes from the cpu/chipset.
Supporting only 3 slots is the maximum that can be serviced.
So no surprises there.
True. I think the most important issue might be an am4 server MB should last longer in the world of 24/7 computing.
Now if I could get that reliable of a ribbon cable expansion splitter :)

If you want to support more slots, you really need to move to workstation boards.
Just discovered that a Thunderbolt 3 port can drive external PCIe expansion boxes. The boxes appear to have external power ports.
And we have some Am4 socket MB's with Thunderbolt 3 ports...

I have two questions. Will it work with my first gen cpus?
Is it a good idea?
It would cost less to spin up a new 5950x box.

Depends how many lanes each socket gets. Most boards support 16x graphics, or 16x/8x, or 8x/8x/8x. So why not go down to 4x and have 6?
I actually have a board that only has ONE 1x slot. PCI Express 2! It's no faster with an NVME on it than a SATA 3 SSD! (Although since it has SATA 2 I did get a 2x performance increase). And now I have nowhere to put the GPU:-( The slot is 16x, but the CPU is only 4 lanes! I think 1 is used for ethernet, 1 for USB and 1 for SATA, and I can't get into the BIOS to switch those off because it doesn't notice a USB keyboard! ARGH! I did try sharing NVME and GPU on one multiplexed lane, but that didn't go well.

George, I’ll think he still has the necessary memory to use this board, maybe Tom can confirm that. He also already has the CPU.
you’re correct that some of his ribbon cables won’t work on this board. Since the x8 slots are closed end slots and will not accept the x16 riser. this is one aspect where the AsRock Rack EPYCD8 boards are better in my opinion. The x8 slots are open ended so you can physically plug in a x16 card without an adapter. Also the AsRock boards have 7 slots vs 6 on the SM board. And finally the AsRock board has a dedicated PCIe power connector on the board that the SM doesn’t have.

If you want to support more slots, you really need to move to workstation boards.
And you will find more choices on Intel cpus/chipsets.
The old x99 Intel boards make fine workstations that can support 7 slots.

Mine always ran superbly after I fixed the manufacturing error of missing thermal pads on the chipset and one of the PCIE Plex driver chips.

Yes your first gen EPYC CPU will work on this board.

Did you see this?
You're going to need multiple riser cables of two different kinds. Remember what you went through before?
Have you seen the prices of 5950X CPU's lately? Have you compared ALL of the costs for a switch to EPYC?

Okay, I'll concede that I wasn't thinking that he already has used EPYC before.
And I agree with you that the AsRock board would be better for Tom.
We need to get him to stop looking at EBAY for used MBs. They may be cheap(er) than others, but at what cost?
