HPM-SIEUA
Series: HPM
The Avalue HPM-SIEUA is a single-socket ATX server board built on the AMD SP6 socket for 4th Generation AMD EPYC processors (max. TDP up to 225W), designed as a manageable, expansion-rich x86 compute platform for edge servers and HPC nodes. With 6 x DDR5 4800/4400MHz RDIMM up to 1.5TB, onboard TPM 2.0 and IPMI 2.0 via an ASPEED AST2600 BMC, it delivers data-center-class AMD EPYC performance in a 12" x 9.6" board. It provides 3 x PCIe Gen5 x16 and 4 x PCIe Gen5 x8 slots, 2 x M.2 M-Key PCIe 5.0 x4 NVMe/SATA, 4 x SATA III via MiniSAS HD 4i, triple Intel Ethernet (I210AT 1GbE, I226-LM 2.5GbE, X550AT2 dual 10GbE), and USB 3.2 Gen1, running Windows Server 2019/2022, Ubuntu 20.04/22.04 LTS or RHEL 9.0+.
