ThinkMate DDR5 4800 ECC RDIMM Kit

This 256GB kit contains sixteen 16GB registered DDR5 modules built for ThinkMate Supermicro SuperServer 521GE-TNRT and 421GU-TNXR platforms. It delivers error-correcting code memory for workloads that require data integrity and system stability.

Registered ECC with CL40 latency

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40, 1.10V operating voltage and a 1Rx8 organisation. The registered buffer and on-die ECC protect against single-bit errors in mission-critical server environments.

Suited for ThinkMate SuperServer upgrades only

Buyers who need consumer UDIMMs, non-ECC memory or a different pin count should look elsewhere. This kit is validated for the two listed ThinkMate SuperServer models and is not intended for desktop or laptop platforms.

Questions about this item

What does 4800 MT/s DDR5 mean for actual throughput in the ThinkMate server?

The kit runs at 4800 MT/s with CL40 latency and 1.1 V, giving a peak bandwidth of PC5-38400 per module across all 16 slots.

How does the 288-pin ECC RDIMM interface limit usable speed?

The registered 288-pin DDR5 RDIMM interface caps operation at the rated 4800 MT/s; the memory controller cannot push the modules beyond this specification.

What physical clearance does the 16-module kit need inside the 421 or 521 chassis?

Each 16 GB stick is a standard-height 288-pin RDIMM without a heat spreader, so it fits the stock DIMM slots in the ThinkMate SuperServer 421GU-TNXR and 521GE-TNRT without extra clearance.
