256GB DDR4 ECC RDIMM kit for ThinkMate servers

This 256GB kit consists of four 64GB DDR4 3200 registered DIMMs built for ThinkMate GPX-XT6-24S3-8NVLINK GPU-optimised servers. Each module runs at PC4-25600 with CL22 latency and 1.20V operation. ECC and registered buffering protect data integrity in mission-critical workloads.

Thermals noise and power at 1.20V

Operating at 1.20V keeps power draw low for high-density server configurations. The modules ship without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, contributing to stable operation under sustained throughput.

Four-module kit enables full population

The package delivers four matched 64GB RDIMMs so administrators can populate all required slots in a single step. Compatibility testing targets the specified ThinkMate platform to minimise boot-time surprises. No additional software or accessories are included beyond the memory modules themselves.

Questions about this item

How do I install the four 64 GB DDR4 RDIMMs into the ThinkMate GPX-XT6-24S3-8NVLINK server, and what step is often missed?

Power down, open the chassis, align each 288-pin module with the DDR4 slots, press firmly until the ejector clips lock, then populate all four channels per the server manual to enable quad-channel operation — skipping the channel-order step leaves bandwidth on the table

What maintenance or replacement will the 256 GB ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; if a 64 GB rank fails, ECC will log correctable errors and the individual DIMM can be swapped under the lifetime replacement guarantee

What limit appears first when the 3200 MHz CL22 4Rx4 registered memory runs sustained workloads on this server?

The CAS 22 latency at 1.20 V sets the timing ceiling; under continuous load the memory controller hits the CL22 cycle budget before thermal or voltage limits become a factor
