This is probably one of the SMALLEST motherboard that I’ve seen for the AMD EPYC CPU. The ASRock Rack ROMED4ID-2T motherboard comes in their proprietary form factor called “Deep” Mini-ITX. Pretty cool huh?
Taken from TPU … ASRock Rack, a branch of ASRock focused on making server products, has today launched a new motherboard that can accommodate up to 64 core AMD EPYC CPU. Built on the new, proprietary form factor called “Deep Mini-ITX”, the ROMED4ID-2T motherboard is just a bit bigger than the standard ITX board. The standard ITX boards are 170 x 170 mm, while this Deep Mini-ITX form extends the board by a bit. It measures 170 x 208.28 mm, or 6.7″ x 8.2″ for all of the American readers. ASRock specifies that the board supports AMD’s second-generation EPYC “Rome” 7002 series processors. Of course, the socket for these CPUs is socket SP3 (LGA4094) with 4094 pins.
The motherboard comes with 4 DDR4 DIMM slots, of any type. Supported DIMM types are R-DIMM, LR-DIMM, and NV-DIMM. If you want the best capacity, LR-DIMM use enables you to use up to 256 GB of memory. When it comes to expansion, you can hook-up any PCIe 4.0 device to the PCIe 4.0 x16 slot. There is also an M.2 2280 key present, so you can fit in one of those high-speed PCIe 4.0 x4 M.2 SSDs. For connection to the outside world, the board uses an Intel X550-AT2 controller that controls two RJ45 10 GbE connectors. There are also two Slimline (PCIe 4.0 x8 or 8 SATA 6 Gb/s), and four Slimline (PCIe 4.0 x8) storage U.2 ports.
