Our take on the Dell EMC Dual Intel Socket (P) FCLGA3647 DDR4 (RDIMM / LRDIMM) 24 Slots 1U Motherboard for PowerEdge R640 Server 0H28RR H28RR

The Dell H28RR (0H28RR) is the system board for the PowerEdge R640, a 1U dual-socket rack server. It takes two Intel Xeon Scalable processors on FCLGA3647 sockets, up to 24 DDR4 DIMMs (RDIMM or LRDIMM) across both CPUs, and runs on the Intel C620 chipset. It is a replacement part for an existing R640, not a board you can drop into a generic case. Buyers are IT teams repairing or rebuilding an R640; the value is in restoring a known-good platform rather than adding new capability over the original board.

Which processors does it support?
It has two FCLGA3647 sockets for Intel Xeon Scalable processors. Match the CPU generation to what the R640 platform and its BIOS support.
What memory can I install?
It has 24 DDR4 DIMM slots and accepts registered DIMMs (RDIMM) or load-reduced DIMMs (LRDIMM). Memory is populated per CPU, so plan slots around how many processors you install.
Does it come with CPUs, memory or heatsinks?
No. This is the motherboard only. Processors, DIMMs, heatsinks and other components are separate.
Can I use it outside a PowerEdge R640?
