An x16 electrical PCIe5 slot is a waste of available bandwidth. That slot should be split out into an x8 and multiple x4 connections. But that would require making a server board and not repurposing a desktop design.

Expansion Slot
(1) PCIe 5.0 x16 slot from CPU
(1) PCIe 4.0 x8 slot (x4 signal) from CPU(shares link with M2_1)

In case you missed it, I’ll point out the last set of parentheses above.

Also, Newegg has the 10G-less, 1G-only version of D3051 for $349. I don’t know why anyone would want a 10G-less version, especially when combined with the above info from manual.

Does MSI see a use case for 400Gb/s networking amongst the budget crowd?

It’s a gaming board design slightly tarted up – add a 10 or 25 Gb/s controller and install the ECC RAM BIOS and call it ‘server’. Much what I expected to be bruited. And why not, since ‘epyc 4004’ is +/- a desktop chip.

Since for a low end 10Gbits (1. 25GB/s) server, there is no need single 121GB/s card, or 4G M2x4 at 30GB/s. For M2 lots of x1 slots would be better.
