1TB DDR5 ECC RDIMM kit for ThinkMate servers

This 1TB kit contains eight 128GB registered DDR5 modules rated at 4800 MT/s with CL40 latency. It targets IT teams upgrading ThinkMate RAX-XS4-21S4 rackmount servers that require ECC registered memory for data-integrity workloads.

288-pin registered DIMMs need compatible DDR5

Each 4Rx4 module plugs into a 288-pin DDR5 RDIMM socket on a qualified ThinkMate motherboard. The registered buffer reduces electrical load on the memory controller, freeing the CPU to address the full 1TB capacity across all populated channels.

1.10V operation keeps power draw low in dense

Running at the standard DDR5 voltage of 1.10V, the modules generate modest heat without onboard spreaders, relying on server chassis airflow for cooling. Registered signalling and ECC overhead add minimal latency while maintaining signal integrity at 4800 MT/s.

Questions about this item

What is the CAS latency that defines timing under sustained server workloads?

The kit runs at CL40, which is the primary timing figure that governs latency during continuous operation.

How much power does each 128 GB module draw at full load in a rackmount chassis?

Each module operates at 1.10 V, so the 8-module kit draws proportionally low power for its density without active cooling.

Which server platform must already be installed for this registered ECC kit to function?

The memory is validated for the ThinkMate RAX-XS4-21S4 rackmount server and requires that system to operate.
