64GB DDR5 ECC RDIMM for Supermicro servers

This 64GB DDR5 4800 registered DIMM adds error-correcting memory to compatible Supermicro UP SuperServer SYS-111C-NR and SYS-521C-NR systems. The 2Rx4 organisation and CL40 latency suit workloads that require data integrity over raw throughput. It operates at the standard 1.1V DDR5 voltage.

Sustained-load behaviour with registered ECC

The registered buffer reduces electrical load on the memory controller, allowing stable operation when all slots are populated under continuous server workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption during long-running compute or storage tasks. Samsung, Micron or Hynix major-brand DRAM chips provide consistent timing at 4800 MT/s.

Straightforward DIMM installation.

The 288-pin module seats in standard DDR5 RDIMM slots without tools; most technicians complete the swap in minutes. Systems that require matched ranks or specific slot-filling orders may reject a single 64GB stick if the platform expects paired modules. Buyers needing larger total capacity should verify the motherboard's maximum supported density per channel before ordering.

Perguntas sobre este artigo

How much power does the 1.1 V DDR5 4800 module draw under sustained server loads?

The module operates at 1.10 V, the standard voltage for DDR5 4800, which keeps power draw lower than previous DDR generations while delivering 38400 MB/s bandwidth.

What motherboard slot and chipset are required to run this 288-pin ECC RDIMM?

A Supermicro motherboard with DDR5 RDIMM slots — such as the X13SEDW-F or the UP SuperServer SYS-111C-NR and SYS-521C-NR — is needed; the registered design and ECC function require a compatible server chipset.

Can I mix this 64 GB 2Rx4 CL40 stick with existing DDR5 4800 modules of different rank or latency?

Mixing ranks or CAS latencies is not recommended; for stability, populate all channels with identical 2Rx4 CL40 modules at 4800 MT/s.
