ThinkMate DDR5 4800 ECC RDIMM Kit

This 256GB kit contains four 64GB registered DIMMs built for ThinkMate TWX-XS8 tower servers. Each module runs at DDR5 4800 with CL40 latency at 1.1V. The 2Rx4 organisation and on-die ECC provide error correction for data integrity in continuous workloads.

Suited for ThinkMate TWX-XS8-24S4

Administrators expanding memory in these qualified platforms can install the kit without configuration changes. Builders using other motherboards, desktop chipsets or unbuffered memory slots should look elsewhere because the registered interface and pin-out are server-specific.

256GB total capacity across four slots

The kit fills four DIMM sockets with 64GB each, giving ample headroom for virtualisation hosts, database buffers and large-file caching. Workloads that require more than 256GB or need higher frequencies than DDR5 4800 will exceed what this kit provides.

Questions about this item

Does this kit require a ThinkMate TWX-XS8-24S4 or TWX-XS8-14S4 tower server to operate?

Yes, the kit is validated for the ThinkMate TWX-XS8-24S4 and TWX-XS8-14S4 tower servers; the motherboard in those systems provides the DDR5 RDIMM slots and registered ECC support the modules need.

Can I mix these 4800 MT/s registered ECC modules with slower DDR5 RDIMMs already installed in the same server?

The server will run all populated slots at the speed of the slowest module, so adding this 4800 MT/s kit alongside slower DDR5 RDIMMs will down-clock the new modules to match the lower rate.

How can I confirm the full 256 GB is recognised and ECC is active after installation?

Enter the system BIOS or UEFI during boot and check the memory information screen; it should show 256 GB total across four 64 GB modules at 4800 MT/s with ECC enabled.
