  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 128GB single-module capacity scales server memory density
  • DDR4 3200 speed with PC4-25600 bandwidth supports demanding workloads
  • ECC registered RDIMM design protects data integrity in critical systems
  • 4Rx4 organisation maximises rank density per DIMM slot
  • 20V operation reduces power draw for high-density configurations

Capacity and Compatibility

This 128GB DDR4 3200 ECC RDIMM module is built for ThinkMate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers. It delivers registered, error-correcting memory in a single 288-pin DIMM for administrators who need maximum capacity per slot.

Sustained Load Behaviour

The module operates at 1.2V with CL22 latency and a 4Rx4 rank structure using major OEM Samsung, Micron or Hynix chips. ECC and registered buffering maintain data integrity and signal stability during continuous, memory-intensive workloads such as virtualization or database processing.

Build and Connectors

No heat spreader is fitted, allowing dense side-by-side population in server chassis with limited DIMM clearance. The standard 288-pin RDIMM keying ensures correct orientation during installation, while the registered interface reduces electrical load on the memory controller for reliable long-term operation.

Questions about this item

How much heat does the 1.2V DDR4 3200 module generate when running continuously in a ThinkMate HDX-QT24-52E3 server?

The module operates at 1.20V with no heat spreader, so it relies on server chassis airflow for cooling; power draw scales with the 128GB 4Rx4 density under sustained load.

Which ThinkMate server models must already be installed for this RDIMM to function?

This 288-pin DDR4 3200 ECC RDIMM is validated for ThinkMate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers.

Will this CL22 4Rx4 module work alongside existing DDR4 3200 RDIMMs of different rank in the same ThinkMate system?

Mixing 4Rx4 modules with other ranks at DDR4 3200 is supported by the ThinkMate memory controller, but the system will run all channels at the slowest common timing.
