2TB DDR5 ECC RDIMM kit

This 2TB memory kit contains sixteen 128GB DDR5 4800 registered DIMMs built for ThinkMate GPU-optimised servers. It targets IT teams expanding capacity in GPX-QH24-24E4-8GPU or GPX-QH14-28E4-8HGX platforms.

Registered 4Rx4 modules at 1.1V

Each module is a 288-pin RDIMM with 4Rx4 organisation, CL40 latency and no heat spreader. Registered buffering and on-die ECC protect data integrity under sustained multi-GPU workloads. The low 1.1V operating voltage reduces power draw across all sixteen slots.

Verify sixteen-slot support

Confirm the motherboard provides sixteen DDR5 RDIMM sockets and qualifies 4Rx4 128GB modules at 4800MT/s. Systems limited to fewer slots or lower ranks cannot use this kit. BIOS revision and memory-channel population rules must also match the vendor's validated configuration.

Questions about this item

What does PC5-38400 mean for real-world throughput on this DDR5 4800 kit?

PC5-38400 is the JEDEC standard name for DDR5 4800; it confirms the modules are rated for 4800 MT/s data rate and 1.10 V operation.

Will these 288-pin RDIMMs fit the memory slots in a ThinkMate GPX-QH24-24E4-8GPU server?

Yes — the kit is validated for ThinkMate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers that accept 288-pin DDR5 RDIMMs.

What is the correct seating order for the 16 modules during installation?

Follow the motherboard manual's population sequence; a common error is filling slots out of order, which prevents the server from recognising the full 2 TB capacity.
