System-Specific DDR5 ECC RDIMM Kit

This 64GB kit contains two 32GB DDR5 4800 registered DIMMs built for SuperMicro SuperServer SYS-221HE variants. It targets IT professionals who need validated ECC memory for mission-critical server workloads.

288-Pin Registered Modules at 1.1V

Each module uses a 1Rx4 organisation with Samsung, Micron or Hynix ICs and runs at the standard DDR5 voltage of 1.10V. The registered design reduces electrical load on the memory controller, supporting stable operation in dense server configurations.

Two-Module Kit for Immediate Installation

The package delivers a matched pair totalling 64GB, eliminating the need to source individual sticks. Modules are stress-tested under load before shipping, so the kit is ready for direct insertion into compatible SuperMicro platforms.

Questions about this item

Does DDR5 4800 PC5-38400 run at 4800 MT/s in the SuperMicro SYS-221HE?

Yes, the kit is rated DDR5 4800 (PC5-38400) and will operate at 4800 MT/s when the platform supports that speed.

Will the 288-pin RDIMM modules fit the SuperMicro SYS-221HE memory slots?

The modules are standard 288-pin DDR5 RDIMMs, matching the DIMM slots used in the SYS-221HE series.

Do I need to populate specific DIMM slots for the 2×32 GB registered ECC kit?

Install one module per channel following the motherboard's population guide; the common mistake is placing both modules in the same channel.
