768GB DDR4 3200 ECC RDIMM kit

This 768GB kit contains six 128GB DDR4 3200 CL22 registered ECC modules built for ThinkMate GPX-PS4 GPU-optimised servers and workstations. It targets IT teams expanding memory capacity in these qualified platforms.

Thermals power and noise

Registered DDR4 modules without heat spreaders run at the standard 1.2V and rely on server chassis airflow for cooling. Power draw scales with the six-module population and the 3200 MT/s data rate.

4Rx4 quad-rank organisation

Each 128GB module uses a 4Rx4 layout, so the memory controller must support quad-rank registered DIMMs at this density. Platforms limited to dual-rank modules cannot use this kit.

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules in the ThinkMate server and what step is often missed?

Power down the server, open the chassis, align each 288-pin module with the keyed slot and press firmly until the ejector clips lock; the step often missed is populating all six slots in the exact channel order shown in the ThinkMate service guide so the 4Rx4 ranks initialise correctly.

What maintenance or replacement will the 768 GB kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; if a DIMM fails the lifetime replacement warranty covers a direct swap of the faulty 128 GB stick.

What limit appears first when the 6 x 128 GB kit runs sustained workloads at 3200 MT/s?

The CL22 latency at 1.20 V is the first bottleneck; sustained throughput is capped by the registered 4Rx4 timing budget before thermal or voltage headroom becomes an issue.
