System-specific DDR5 ECC kit

This 128 GB kit contains two 64 GB DDR5 4800 registered DIMMs built for Supermicro X13SET-G and X13SET-GC motherboards. It targets administrators who need error-correcting memory in dual-processor or single-processor server workloads. The modules operate at 1.1 V with a CAS latency of CL40. Buyers needing non-ECC consumer memory or higher-speed bins should look elsewhere.

Rank and voltage configuration

Each module uses a 2Rx4 organisation with Samsung, Micron or Hynix chips, delivering the registered signal buffering required by the qualified platforms. The 1.1 V operating voltage matches the DDR5 baseline for these boards, so no manual voltage adjustment is necessary. Systems that cannot accept registered DIMMs or that require unbuffered memory will not post with this kit.

Installation notes

The 288-pin DDR5 form factor fits the standard server DIMM slots on the listed Supermicro boards; align the key notch and press until the ejectors click. Common issues include mixing this kit with existing modules of different rank or speed, which forces the platform to down-clock or halt at POST. Always populate slots per the motherboard manual for the correct channel layout.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need firmware updates or periodic replacement under server workloads?

DDR5 ECC RDIMM modules have no firmware to update and no scheduled replacement interval; ECC corrects single-bit errors on the fly while the registered buffer reduces electrical load on the memory controller.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s data rate sets the peak bandwidth ceiling; CL40 latency affects access delay but does not cap sustained throughput once the pipeline is full.

How much heat and power do the 1.1 V modules produce when running all day in a Supermicro X13SET-G chassis?

Each 64 GB module operates at 1.10 V with no heat spreader, so power draw stays low and airflow from standard server fans keeps temperatures within normal DDR5 operating limits.
