Designed for ThinkMate 111E-WR servers

This 128 GB DDR5 registered DIMM kit is built specifically for the ThinkMate Supermicro SuperServer 111E-WR platform. It contains two 64 GB modules that deliver ECC protection and registered signalling for stable operation in mission-critical workloads. The kit targets IT professionals who need guaranteed compatibility without manual qualification.

Sustained-load behaviour

Modules are stress-tested under continuous load to verify reliability during extended server duties. Registered buffering and on-die ECC correct errors in real time, preventing data corruption during long compute runs. The 1.1 V operating voltage helps maintain thermal headroom when all slots are populated.

The deciding specification

Registered ECC RDIMM format with CL40 latency at 4800 MT/s is the single factor that determines fit. Only systems that accept 288-pin DDR5 registered ECC modules at this speed and rank configuration can use this kit. Builders needing unbuffered or non-ECC memory must choose a different product.

Questions about this item

How much power does the 1.10 V DDR5 4800 kit draw when the server runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 128 GB capacity and workload rather than a fixed wattage figure.

What motherboard feature must the THINKMATE 111E-WR already provide for these registered ECC modules to function?

The board must support 288-pin DDR5 RDIMM slots with ECC and registered buffering enabled in the memory controller.

Will the CL40 registered ECC sticks work alongside other DDR5 RDIMMs already installed in the chassis?

Yes, provided the other modules are also DDR5 RDIMM ECC registered; mixing speeds or ranks will force the system to run at the lowest common timing.
