Target system and purpose

This memory kit is built for THINKMATE SuperServer 511E-WR and 521E-WR platforms. It supplies 256 GB of registered ECC DDR5 across four modules for server and workstation workloads that demand data integrity.

Deciding specification

The kit runs at DDR5 4800 with a CAS latency of CL40 at 1.1 V. Each 64 GB module is a 2Rx4 288-pin RDIMM, so the motherboard must support registered ECC DDR5 at this speed and density.

Build integration

Four DIMM slots are required to populate the full 256 GB capacity. The registered design reduces electrical load on the memory controller, and ECC provides error correction for mission-critical stability. No heat spreaders are included.

Questions about this item

What does the 4800 MT/s speed mean for my ThinkMate server in practice?

The modules run at DDR5 4800 (PC5 38400) so the server's memory controller will operate at that data rate without manual tuning.

How does the 288-pin ECC RDIMM interface limit what I can install?

The kit uses 288-pin DDR5 RDIMM modules with ECC and registered buffering; only motherboards that accept DDR5 RDIMM ECC memory can use them.

Will the four 64 GB sticks fit in a ThinkMate 511E-WR or 521E-WR chassis?

Each module is a standard 288-pin DDR5 RDIMM with no heat spreader, so they install in the server's regular DIMM slots.
