Server memory for ThinkMate GPU servers

This 768 GB kit provides six 128 GB DDR4 3200 ECC registered DIMMs validated for ThinkMate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU platforms. It targets IT teams expanding GPU-optimised servers that require high-capacity registered memory with error correction.

Low-voltage DDR4 at standard JEDEC timings

Modules operate at 1.20 V with CL22 latency and 4Rx4 organisation. Registered buffering reduces electrical load on the memory controller, helping maintain stability under sustained GPU compute workloads without additional cooling requirements.

288-pin RDIMM form factor with major OEM chips

Samsung, Micron or Hynix components populate each stick. The kit ships as a matched set of six modules for straightforward population of all available slots in compatible ThinkMate chassis, simplifying large-capacity upgrades.

Questions about this item

How do I install the six 288-Pin DDR4 RDIMM modules in the ThinkMate server, and which step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 768 GB are detected at 3200 MT/s.

What maintenance or replacement will this 4Rx4 ECC registered kit need during its service life?

The modules have no heat spreaders and no moving parts; only periodic dust removal from the DIMM slots is required, and any failed stick is covered by the manufacturer's lifetime replacement warranty.

What limit appears first when this 1.20 V CL22 memory runs sustained workloads on the GPU-optimised ThinkMate platform?

The registered 4Rx4 organisation and CL22 latency set the throughput ceiling, so sustained bandwidth tops out at the DDR4 3200 PC4-25600 rating before thermal or voltage limits are reached.
