ThinkMate DDR5 4800 ECC RDIMM kit

This 512 GB kit contains four 128 GB DDR5 4800 registered DIMMs built for the ThinkMate GPX-XH8-22S4-8GPU server. ECC and 4Rx4 organisation protect data integrity in GPU-optimised workloads. It targets administrators scaling memory for AI training, rendering or virtualisation clusters.

Thermals and power at 1.1 V

Modules run at 1.10 V with no heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained throughput. The CL40 latency and PC5-38400 rating reflect standard JEDEC operation without overclocking headroom.

Build integration and capacity gains

Four 288-pin slots are required to install the full kit, freeing remaining DIMM sockets for future expansion. Registered signalling allows higher module counts per channel than unbuffered alternatives. Buyers needing non-ECC consumer memory or lower-density sticks should look elsewhere.

Questions sur cet article

How do I install four 288-pin DDR5 RDIMM modules into the ThinkMate GPX-XH8-22S4-8GPU server, and which step is most often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the ejector tabs click, then verify all 512 GB are recognised in BIOS before closing the case; the step most often missed is confirming the BIOS sees the full capacity.

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

No routine maintenance is required; the modules are covered by a lifetime replacement warranty, so a failed stick is swapped for a new one rather than repaired.

At what point does the CL40 latency at 4800 MT/s become the limiting factor under sustained workloads?

The CL40 timing at 4800 MT/s is the first latency ceiling you hit during sustained memory-bound workloads, before bandwidth or thermal limits appear.
