ThinkMate Server Memory Kit

This 512 GB kit combines four 128 GB DDR4 3200 registered ECC RDIMMs validated for ThinkMate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers. It targets IT teams expanding memory capacity in those specific platforms.

Registered ECC Modules For Qualified Slots

Each 288-pin module operates at 1.2 V with CL22 latency and a 4Rx4 organisation. The registered design reduces electrical load on the memory controller, allowing all four DIMMs to populate qualified slots without additional buffering hardware.

Sustained Load Stability

Modules are stress-tested under load using major OEM Samsung, Micron or Hynix components to maintain data integrity during continuous server workloads. ECC correction and registered signalling preserve throughput when the system runs at full capacity for extended periods.

Questions about this item

Will 4Rx4 organisation at CL22 limit bandwidth when all four slots are populated?

The kit runs at DDR4 3200 with CL22 timing; 4Rx4 rank structure is supported by the qualified ThinkMate platforms.

How much heat do four 128 GB registered modules generate at 1.20 V under continuous load?

Modules operate at 1.20 V without heat spreaders; registered buffering reduces electrical load per pin during sustained operation.

Which ThinkMate server models are validated for this 512 GB kit?

Qualified systems include HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers.
