Micro-ATX EPYC and Ryzen server board

The ASRock Rack B650D4U3-2L2Q/BCM is a Micro-ATX server motherboard built for AMD EPYC 4004, 4005 and Ryzen 9000, 8000, 7000 series processors. It fits single-socket systems that need ECC memory and high-speed networking in a compact footprint.

Suits single-CPU servers needing 25GbE and ECC

Builders assembling storage nodes, edge appliances or virtualisation hosts with one processor will match the board's feature set. Buyers who want more storage than four SATA ports provide, or who need multi-processor scaling, should look at something else.

Dual 25GbE SFP28 decides the network fit

Onboard Broadcom BCM57502 gives two 25Gbps SFP28 links plus two 1Gbps RJ45 ports from an Intel I210 controller. If the deployment requires fibre uplinks at 25GbE this board matches; otherwise a 1GbE-only board covers the same basics.

Ερωτήσεις για αυτό το προϊόν

How do I install the AMD EPYC 4004 or Ryzen processor into the SP5 socket, and what step is most often missed?

Align the triangle on the CPU with the socket corner, lower the retention frame, then torque the captive screws in a cross pattern to the specified pressure; the step most often missed is applying the correct mounting pressure for the 170W TDP cooler bracket.

What maintenance or replacement will the DDR5 ECC UDIMM memory need over time?

The four 288-pin slots support up to 192GB of DDR5 5600 ECC UDIMM; modules only need replacement if a correctable error count exceeds the platform threshold or a DIMM fails POST, otherwise no scheduled swap is required.

What thermal limit appears first when the 25GbE Broadcom BCM57502 SFP28 ports run sustained line-rate traffic?

The SFP28 transceiver modules typically hit their case-temperature threshold before the Broadcom BCM57502 controller does, so adequate chassis airflow over the cage assemblies is the first practical limit.
