256GB DDR4 ECC RDIMM kit

This 256GB kit contains two 128GB DDR4 3200MHz registered DIMMs with ECC and a CAS latency of CL22. It operates at 1.2V using a 4Rx4 organisation across 288 pins. The modules are validated for ThinkMate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU GPU-optimised servers.

Upgrading from lower-capacity RDIMMs

Replacing smaller registered ECC modules with this 2x128GB kit doubles or quadruples the memory available to each CPU socket. The jump is worth it when virtualisation hosts, GPU compute nodes or large in-memory databases hit capacity limits on the existing configuration.

Suited for ThinkMate GPU servers

This kit suits administrators expanding ThinkMate GPX-PS4 platforms that require registered ECC memory at DDR4 3200 speeds. Builders needing unbuffered UDIMMs, non-ECC modules, DDR5 speeds or single-rank densities should look at something else.

Questions about this item

Does this kit use the standard 288-pin DDR4 RDIMM form factor for server DIMM slots?

Yes, each module is a 288-pin DDR4 RDIMM that fits standard registered server DIMM slots.

Are there any special population rules for the 4Rx4 organisation on a ThinkMate GPX-PS4-12A1 system?

Install the two 128 GB modules in the channels indicated by the system manual; 4Rx4 ranks require correct slot order to initialise.

Will the Samsung, Micron or Hynix DRAM chips need active cooling over time?

The modules ship without heat spreaders and run at 1.20 V; typical server airflow is sufficient for long-term operation.
