ThinkMate DDR5 4800 ECC RDIMM 256GB Kit

This 256GB kit contains two 128GB DDR5 4800 registered ECC RDIMMs built for ThinkMate TWX-XS8 tower servers. It targets IT teams running virtualisation, database or high-throughput workloads that require error-correcting registered memory.

Installation notes and common issues

Modules are 288-pin DDR5 RDIMMs that seat in standard server DIMM slots; installation typically takes minutes per the system manual. The 4Rx4 organisation and CL40 latency must match the platform's qualified configuration, otherwise the server may fail to post or run at reduced speed.

Capacity headroom and limits

The dual-rank 256GB total provides ample headroom for multi-tenant VMs and large in-memory datasets at 1.1V. Workloads that scale beyond 256GB or demand higher frequencies than DDR5 4800 will exceed this kit's capability.

Questions about this item

How can I confirm the kit is running at DDR5 4800 with CL40 after installation?

Check the BIOS memory information screen — it should report DDR5 4800 speed and CL40 latency for the registered ECC modules.

What is included in the package and is anything else required?

The box contains two 128GB DDR5 4800 ECC RDIMM modules; no extra components are needed for installation in compatible ThinkMate tower servers.

Which capacity option should I choose for a ThinkMate TWX-XS8-24S4 or TWX-XS8-14S4?

This 256GB kit (2 x 128GB) is the listed configuration validated for those ThinkMate tower servers.
