2TB DDR5 4800 ECC RDIMM Kit

This 16-module kit delivers 2 TB of registered DDR5 memory for ThinkMate GPX-XH20-28S4-8HGX GPU-optimised servers. Each 128 GB module runs at 4800 MT/s with CL40 latency and 1.1 V operation. ECC and registered buffering protect data integrity in mission-critical workloads.

Ideal for High-Capacity Server Upgrades

IT teams expanding memory in the validated ThinkMate platform will match the qualified configuration exactly. Environments that need unbuffered UDIMMs, non-ECC modules or speeds above 4800 MT/s should select a different kit.

4Rx4 Registered DDR5 Architecture

The 4Rx4 organisation across 288-pin RDIMMs determines electrical loading and rank-per-channel limits on the target server. Confirm the platform supports this rank structure before purchase.

Questions about this item

Will the 288-pin DDR5 RDIMMs fit the memory slots on the ThinkMate GPX-XH20-28S4-8HGX server?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the server's DIMM sockets.

What is the correct way to populate all 16 slots with these 4Rx4 modules?

Follow the server manual's population order exactly; the common mistake is skipping the prescribed sequence for quad-rank DIMMs.

How can I tell if a module needs replacement after extended ECC-corrected error logging?

Persistent correctable-error counts that exceed the platform's threshold indicate a module should be swapped out.
