1.5 TB DDR4 ECC RDIMM kit

This 1.5 TB kit contains twelve 128 GB DDR4 3200 registered DIMMs built for ThinkMate GPX-XT6-24S3-8NVLINK servers. ECC and 4Rx4 organisation protect data integrity under sustained GPU-optimised workloads. The modules run at 1.2 V with a CL22 latency profile.

Replacing lower-capacity or non-ECC DDR4

Swapping standard unbuffered DIMMs for this registered ECC kit adds error correction and quadruple-rank density, letting the platform address the full 1.5 TB. The jump is worth it when virtualisation, large-model inference or multi-GPU compute saturates smaller memory configurations.

Verify 288-pin DDR4 RDIMM slots

Confirm the server board provides twelve 288-pin RDIMM sockets and that the BIOS supports 4Rx4 modules at 3200 MT/s. Ensure the operating system and applications can utilise the full capacity before ordering.

Questions about this item

Will these 288-pin DDR4 RDIMMs fit the DIMM slots in my ThinkMate GPX-XT6-24S3-8NVLINK server?

Yes, each module is a 288-pin DDR4 RDIMM, the standard form factor for the ThinkMate GPX-XT6-24S3-8NVLINK platform.

What is the correct order for populating the twelve 128 GB modules across the 24 available slots?

Follow the server manual’s population sequence; typically you fill one DIMM per channel first, then add the second rank, ensuring identical 4Rx4 modules occupy matching slots.

How do I know when a 4Rx4 registered ECC module in this kit should be replaced?

The server’s management console logs corrected and uncorrected ECC events; replace any module that shows rising error counts or fails the built-in memory diagnostics.
