768GB DDR4 RDIMM kit for Thinkmate servers

This 12-module kit delivers 768GB of DDR4 3200 registered ECC memory built for Thinkmate HDX-QT24 and HDX-QN24 high-density servers. Each 64GB module uses a 4Rx4 organisation at 1.2V with CL22 timing. The kit targets IT teams expanding memory capacity in qualified Thinkmate platforms.

Capacity headroom for dense virtualisation

Twelve 64GB RDIMMs fill 12 slots to reach the 768GB total, supporting large virtual-machine counts and in-memory databases on compatible Thinkmate systems. Registered buffering and ECC protect data integrity under sustained load. The 4Rx4 rank structure maximises density per slot; configurations needing more than 768GB or fewer than 12 populated slots fall outside this kit.

288-pin registered modules without heat spreaders

Modules are standard-height 288-pin DDR4 RDIMMs using Samsung, Micron or Hynix components and no heat spreaders, so they fit tightly spaced server DIMM sockets. Registered signalling reduces electrical load on the memory controller. Buyers needing unbuffered UDIMMs, non-ECC memory or lower-density 32GB modules cannot use this kit.

Questions about this item

Will these 12 64 GB RDIMMs work with the DDR4 3200 registered memory already installed in my ThinkMate server?

The kit supplies twelve 64 GB DDR4 3200 ECC RDIMMs at 1.2 V, CL22, 4Rx4, 288-pin. They are built for the ThinkMate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 platforms. Matching speed, voltage, rank and registered type is required for mixed operation.

How can I confirm the 768 GB kit is running at 3200 MHz with ECC active after installation?

Enter the server BIOS or UEFI and verify the memory frequency reads 3200 MT/s (PC4-25600), CAS latency 22, voltage 1.2 V and ECC status enabled. Operating-system tools such as dmidecode or IPMI sensors will also report 12 modules at 64 GB each with ECC functional.

What comes in the box and what extra parts are needed to install the 12 modules?

The package contains the 12 x 64 GB DDR4 3200 ECC RDIMM modules only. No heat spreaders, cables, brackets or tools are included. The server chassis provides the DIMM slots and retention clips; an anti-static wrist strap is recommended but not supplied.
