SuperMicro DDR5 4800 ECC RDIMM Kit

This 64 GB kit uses two 32 GB DDR5 4800 registered DIMMs built for SuperMicro SuperWorkstation SYS-531A-I and X13SRA-TF platforms. ECC and registered buffering protect data integrity in servers and workstations running continuous workloads.

Registered ECC modules for error correction

Registered buffering reduces electrical load on the memory controller while ECC detects and corrects single-bit errors automatically. The 1.1 V operating voltage and CL40 latency are factory-set for the qualified SuperMicro systems. No heat spreader is included, so airflow in the chassis handles cooling.

Simple DIMM installation with manual guidance

Modules insert into the 288-pin DDR5 slots on the supported SuperMicro motherboards. The owner's manual provides the exact slot population order; skipping that step is the most common cause of a no-post condition. Buyers who need non-ECC unbuffered memory or a different capacity cannot use this kit.

Questions about this item

Will the 1Rx4 DDR5 4800 RDIMM modules need firmware updates or re-training after long-term operation?

Registered ECC RDIMM modules do not require firmware updates; the memory controller handles training at each POST, so no user maintenance is needed.

What latency ceiling appears first when the kit runs continuously at CL40?

The CAS latency of CL40 is the fixed timing ceiling; sustained workloads cannot push latency lower than the programmed 40 cycles.

How much heat and power do the 1.1V DDR5 modules draw under constant load?

Each 32GB 1Rx4 stick operates at 1.10V, so the pair draws low power and produces minimal heat without a heat spreader.
