2TB ECC RDIMM Kit for ThinkMate Servers

This kit delivers 2TB of registered DDR4 memory across sixteen 128GB modules, purpose-built for ThinkMate GPX-QN6-42E2-8NVLINK GPU-optimised servers. It targets administrators scaling memory capacity in enterprise workloads that demand error correction and registered signal integrity.

DDR4 3200 Registered Interface Limits

The modules operate at DDR4 3200 (PC4-25600) with a CAS latency of CL22 and a voltage of 1.20V. Registered buffering and 4Rx4 organisation add command-address latency and electrical load, which can restrict maximum DIMM-per-channel counts and achievable frequencies on some server platforms.

16-Module Capacity and Headroom

Sixteen 128GB RDIMMs fill a large number of memory slots, providing substantial headroom for virtualisation, in-memory databases and GPU-accelerated compute. Systems with fewer than sixteen slots or lower per-slot limits cannot accept the full kit, and platforms capped below 2TB total capacity will leave modules unused.

Questions about this item

How do I choose between the 16-module kit and smaller capacities?

This kit provides 2TB total capacity across 16 modules of 128GB each, so you must populate all 16 slots to reach the full amount.

What does the 3200 speed mean once the modules are installed in a server?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency and 1.2V voltage, delivering registered ECC bandwidth for the qualified ThinkMate platform.

What does the 288-pin RDIMM interface cap in practice?

The 288-pin DDR4 RDIMM form factor with 4Rx4 organisation and registered buffering is keyed for compatible ThinkMate server motherboards supporting that pinout and rank structure.
