AsRock is really pushing the ITX form factor to it's limits. No other manufacturer comes close to them, as far as I know, when it comes to supporting SFF high performance PC's.
There's two unpopulated footprints for DDR4 SO-DIMM on the bottom of the board. I have no idea if ECC So-DIMMS exist or if you can mix and match them with regular UDIMMs but thats where the 2 extra slots are. You can see them on the board bottom picture in the article.
from ASRock Rack product sheet PDF(EPC621D4I-2M - EPC621D6I) "4 DIMM slots, Supports Quad Channel DDR4 2993/2666/2400 ECC SO R DIMM, ECC SO DIMM, and non-ECC SO DIMM (Max. 64GB)" there are SO R DIMM ????? where ?

Why.... oh WHY no 10GbE?mode_13h - Thursday, May 9, 2019 - link
I know, right? 2x NVMe's and no 10 Gb Ethernet?They probably expect the PCIe slot to be filled with a 100 Gb NIC.

I guess they figure you could use the card for that, if that's its main job. Or plug something into the USB 3.0?fazalmajid - Wednesday, May 8, 2019 - link
5G deployments are more likely to rely on the Xeon D-2100, it's curious that's not the target platform.mode_13h - Saturday, May 11, 2019 - link
It turns out there's also a version of this board with 6 DIMM slots! Not sure where they put them - maybe in place of the PCIe slot?timecop1818 - Sunday, May 12, 2019 - link

So how exactly are you supposed to feed that Skylake-SP power horse with data? Using the two shitty Marvel GbE ports? Come on...Rollo3647 - Saturday, May 11, 2019 - link
all of my skylake-sp have UDIMM enabled, got a cascade-lake, UDIMM disabled. seems we have a problem.Rollo3647 - Thursday, May 23, 2019 - link

It seems like Apacer is currently the only provider of such ram modules.https://industrial.apacer.com/en-ww/DRAM/DDR4-SORD...
