Single-Socket EPYC Server Board

The ASRock Rack GENOAD8QM3-2T/BCM is a CEB form-factor motherboard built for one Socket SP5 processor. It accepts AMD EPYC 9004 and 9005 series CPUs with a thermal design power up to 400 W. Eight DDR5 288-pin slots support registered DIMMs up to 4 TB total capacity. Dual 10 Gbps LAN and an OCP NIC 3.0 slot handle high-throughput networking.

Suited for Dense Compute, Not Multi-Socket

This board fits builders who need a single high-core-count EPYC host with extensive PCIe 5.0 and CXL 2.0 connectivity. It serves storage-heavy nodes, GPU-accelerated workloads, or memory-intensive applications. Buyers who require two or more processor sockets on one PCB must choose a different platform. Systems needing integrated graphics beyond the Aspeed AST2600 management controller should look elsewhere.

Eight-Channel DDR5 Decides Capacity

The eight memory slots are the primary factor that determines whether this motherboard matches your workload. They deliver 4 TB maximum registered DDR5 capacity at 4800 MT/s, with QVL-validated modules up to 96 GB per DIMM. If your application demands more memory channels or a higher per-slot limit, this board will not meet the requirement.
