ASRock Rack Mini ITX Mboard Supports 28 Cores and Six Channel RAM

ASRock introduces the new motherboard EPC621D4I-2M and EPC621D6I mini-ITX LGA 3647 motherboards that support six channel memory module and Intel first and second generation Xeon Scalable processor that range up to 28 cores.


This tiny motherboard socket type is LGA 3647, and power supply connector by 24 pin and a 8 pin EPS power connector.

This Cascade Lake Xeon Scalable multi-core processor span up to 28 cores and 205W TDP.

The EPC621D6I features six DDR4 SO-DIMM memory slots in total by replacing the two rear M.2 slots with DDR4 SO-DIMM memory slots. At the moment, there aren’t any hexa-channel SO-DIMM memory kits on the market, but we expect to see them soon.

The duo of motherboards employs the Intel C621 chipset and has a PCIe 3.0 x16 expansion slot. Basic storage options include one SATA DOM (Disk on Module) port and one standard SFF-8643 port. An ASpeed AST2500 management processor takes care of the Baseboard Management Controller (BMC) duties, while the Marvel 88E1514-MNP2 controller provides internet connectivity via the pair of Gigabit Ethernet ports. The rear panel also houses the D-Sub port for the BMC’s video output and two USB 3.1 Gen 1 ports.

Both motherboards are excellent mini-ITX options and choosing one over the other really depends on if you value having more memory than storage or vice versa. In terms of compatibility, the SO-DIMM slots support standard SO-DIMM and specialized EEC (error-correcting code) SO-DIMM memory modules with speeds up to DDR4-2999. The M.2 ports conform to the PCIe 3.0 x4 standard and can shelter both PCIe and SATA M.2 2280 drives.

ASRock Rack hasn’t revealed the availability or pricing for the EPC621D4I-2M and EPC621D6I motherboard
