32 GB dual-channel DDR5-4800 ECC registered kit, CL40 at 1.1 V, validated for Thinkmate SuperServer 111E-WR
This 32 GB DDR5 kit is built for the Thinkmate SuperServer 111E-WR. It contains two 16 GB registered DIMMs with ECC for error correction in mission-critical workloads. The modules run at 4800 MT/s with a CL40 latency at 1.1 V. No heat spreaders are fitted.
The single specification that determines compatibility is the registered ECC RDIMM form factor. Only motherboards that accept 288-pin DDR5 RDIMMs with on-die ECC can use this kit. Unbuffered or non-ECC slots will not work. The 1Rx8 organisation and PC5-38400 rating are fixed by the module design.
This kit suits administrators expanding memory in the specified Thinkmate SuperServer. It is not for desktop PCs, workstations requiring unbuffered DIMMs, or any system that cannot address registered ECC modules. Builders needing higher capacities or different speeds must select a different part.

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput when the server’s memory controller negotiates that speed.
Registered DDR5 adds a clock cycle of buffering for signal integrity, letting the 111E-WR’s memory controller drive two 16 GB ranks at 4800 MT/s without exceeding electrical load limits.
Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits the server’s DIMM slots and any stock air-baffle without extra clearance.
