Asrock Rack ROMED8-2T ATX Server Motherboard AMD EPYC 7003 (with AMD 3D V-Cache Technology)/7002 series processors SP3 (LGA 4094) Dual 10GbE

Pros: 7 Gen4 x 16 PCI-E slots
Extra 10G capable USB-C case panel header and port connected to standalone USB controller chip.
Embedded VGA and IPMI, so you have no need worry about headless setup in case of GPU pass-through.
No fans. Fans especially small break fast. It produce noise. Having custom fans on main-board that are hard to replace is no good for building a system that expected to work 24/7 for years.
10G Ethernet. No use now, but extensibility.
Likely would be able to host EPYC Milan CPUs. Cons: Number of USB ports on back-panel can be increased but still we have improvement over EPYCD8-2T.
M.2 slots connected to different NUMA nodes. EPYC CPU is internally a NUMA system. Connecting both to same NUMA node can improve performance in RAID setups. This can be worked around with PCI-E to M.2 adapter, but this takes PCI-E slot.
Package includes extra OCuLink to SATA cable (P/N JPC P4713SP10600-1), however motherboard manual/BIOS say absolutely nothing about capability of connecting extra SATA devices to OCuLink port. Is this board capable of more than 8 drives over SFF connectors as declared? Operating system actually detects 32 ATA interfaces/ports in the system. Manual says nothing about it.
No SATA connectors. Have to use special SFF cables to connect SATA devices. But, my PC case has builtin SATA dock that I have nowhere to plug into. Special cable coupler needed.
Default jumper settings are not straightforward. However this is not an issue if you read manual before using a board. Overall Review: After struggling to upgrade my PC to one that has everything I really want from it based on Intel platform for years I have landed to AMD Threadrippers. I was very disappointed in MB picks of TRX4 platform because all include custom fans (multiple in many cases) on it. Only board I have found without fans was TRX40D8-2N2T. However, for my use case I needed more USB ports and one extra PCI-E slot. So, having no suitable MB picks for TRX4 I have started to look into EPYC. And, this is my choice. Platform offers 128 PCI-E 4.0 lanes. Double of what Threadtipper. It offers 8x DDR4 channels. Again double. Of course there is Threadripper PRO. But it is unfortunately exclusive to Lenovo.
Sacrifice is in max turbo frequency for CPU. In my use case this is OK.
One major benefit. EPYC is a system-on-chip. Motherboard does not have chipset on it. Thanks to this fact it is up-gradable and likely would be able to host future Milan CPUs.
My final build includes:
2x Assorted discrete GPUs.
1x Extra USB controller.
1x Extra SAS storage controller to host more SATA devices.
6x 2.5 SATA SSDs
8x Low-noise 2.5 SATA HDDs.
2x M.2 NVM-E SSDs.
1x EPYC 7302 CPU that will be replaced with Milan based CPU having more cores in about 2 years.
8x 16 GB DDR4 3200 ECC RDIMM modules.
1x Low-noise CPU cooler with 2x fans.
4x Assorted low-noise case fans.
1x 1300W PSU. This is somewhat overkill, but thanks to it PSU fan sinning low (just because load is too low for this PSU) and it does not produce noise.
System can run 2x different guest operating systems with dedicated GPUs and dedicated 10G capable USB 3.0 controllers. You could play heavy games in one guest while other is actively used for GPGPU computations. System stays very quiet.

Pros: 6 PCI-e Gen 4 slots that are always x16/x16 (The 7th may have fewer or be disabled entirely depending on how you configure other options)
Technical support was excellent. William replied quickly and kept replying quickly until my issue was resolved.
IPMI for remote administration.
2 x 10 gigabit ethernet ports may potentially free up a PCIe slot depending on your needs.
Supports “Above 4G Decoding”. This feature might be common now, but its absence will prevent motherboards from being able to use some Data Center GPUs. Cons: I’ll note that for my PC Case (Fractal Meshify 2XL), there was barely enough room access the ethernet cable release tab when removing ethernet cables. Overall Review: No problem installing 4 x NVidia Teslas and having full bandwidth to each. Everything “just worked.”
System Specs:
Fractal Meshify 2 XL case
Epyc 7252 (8C/16T) with Noctua NH-U9 TR4-SP3 cooler
4 x Tesla M40 GPUs (Cooled via a Noctua NF-A14 iPPC-3000).
1TB Intel 665p M.2 SSD
EVGA Supernova 1600 T2 80+ Titanium, 1600W
128GB RAM (2 x Crucial CT64G4LFQ4266 DDR4 2666)
Note that used “AMD Epyc” CPUs from some vendors may be effectively vendor locked. As such, they may not work on motherboards from a another manufacturer. Search for “AMD PSB Vendor Locks” for more information.

Pros: This is a good mobo for AMD Epyc, supports lots of RAM and PCIe, NVME, etc. Cons: The problem is that the system headers are too close to the edge of the board and point outward (not up). After connecting power switch, reset switch, LEDs for power on, and HDD activity, they stick out too far for the mobo to be attached to the chassis. Even jamming the connectors into the side wall doesn’t work (not to mention a bad idea) We encountered this problem with both Rosewill RSV-L4412 and iStarUSA D-400-6-ND chassis. Overall Review: Be very careful on chassis selection.

Overall Review: I ordered a New ROMED8-2T and Newegg sent me an Open Box, confirmed by AsRock Rack as having been sent to them for inspection by sharing the serial number with them. The box and antistatic bag were not sealed and the box was damaged.
Newegg never properly packs an order – it’s always banging around inside the outer box. Extremely disappointing when they are shipping expensive and delicate electronics.
