Compatible SuperMicro Server Memory

This 64 GB kit contains two 32 GB DDR5 4800 RDIMM modules built for SuperMicro Storage SuperServer platforms. It targets administrators who need registered ECC memory validated for the SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW-F systems. The modules operate at 1.10 V with a CL40 latency and use a 1Rx4 organisation based on major OEM DRAM.

Registered ECC RDIMM Integration

Each stick is a 288-pin registered DIMM that plugs directly into the server motherboard slots without a heat spreader. The registered buffer reduces electrical load on the memory controller, freeing the platform to populate more slots per channel. ECC circuitry corrects single-bit errors on the fly, protecting data integrity in storage workloads. No additional cooling or configuration beyond standard BIOS detection is required.

64 GB Capacity Headroom

The dual-rank kit delivers 64 GB total, suitable for virtualisation hosts, database caches and high-thread-count storage nodes. It handles typical multi-tenant workloads and large metadata operations within this footprint. Environments that scale beyond 64 GB per socket or require higher memory bandwidth than PC5-38400 provides will need larger or faster modules.

Questions about this item

Will the CL40 latency become a bottleneck during sustained server workloads?

CL40 is the rated CAS latency for this DDR5 4800 kit; latency does not change under load, so the limit is the fixed 40-cycle timing at 4800 MT/s.

How much heat and power will two 32 GB registered DIMMs add when running 24/7?

Each module operates at 1.10 V with no heat spreader; registered DDR5 RDIMMs at this voltage typically add modest heat and power per DIMM under continuous use.

What motherboard slot and chipset support do I need for this 288-pin DDR5 RDIMM kit?

You need a Supermicro motherboard with 288-pin DDR5 RDIMM slots that supports 1Rx4 registered ECC modules at 4800 MT/s.
