768GB DDR5 4800 ECC RDIMM kit

This 768GB kit contains twelve 64GB DDR5 4800 registered ECC modules built for ThinkMate RAX-XS4-21S4 rackmount servers. It targets IT teams who need maximum memory capacity for virtualisation, databases or high-performance computing workloads.

288-pin registered DIMMs for ThinkMate servers

Each module is a 2Rx4 288-pin RDIMM operating at 1.1V with CL40 latency. The registered buffer reduces electrical load on the server memory controller, allowing all twelve slots to be populated without signal-integrity issues. No heat spreaders are fitted, so airflow in the chassis must be sufficient for dense configurations.

Twelve-module kit validated for ThinkMate

The kit ships as a matched 12 x 64GB set tested under load for compatibility with the specified ThinkMate platform. Major OEM DRAM from Samsung, Micron or Hynix is used. Buyers who need a different capacity, speed or non-ECC configuration should select another kit.

Questions about this item

Will the 4800 MT/s speed hold under continuous server workloads?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, which is the JEDEC base specification; sustained throughput will not exceed this rated speed.

How much heat does a full 12-module kit produce when running 24/7?

Each 64 GB RDIMM operates at 1.10 V without a heat spreader; total power draw scales with all 12 modules populated, so airflow across the 288-pin slots must handle the combined thermal load.

Which Thinkmate server do I need to already own for this 768 GB kit to work?

The kit is validated for the Thinkmate RAX-XS4-21S4 rackmount server; the motherboard must provide 12 DDR5 RDIMM slots and support 2Rx4 registered ECC modules.
