128 GB DDR5 ECC RDIMM for Thinkmate

This registered DDR5 module delivers 128 GB of error-correcting memory at 4800 MT/s with a CAS latency of 40. It is built for the Thinkmate GPX-QH12-12E4-2GPU GPU-optimised server and similar workstations that require registered ECC DIMMs. The single-module design suits upgrades where maximum capacity per slot is needed.

Verify DDR5 RDIMM support and slot population rules

Confirm the motherboard accepts 288-pin DDR5 RDIMMs and supports 4Rx4 organisation at 1.10 V. Check the system manual for approved memory configurations, maximum capacity per channel, and any required population order before installing this module. Ensure the platform can operate at the rated PC5-38400 speed.

Major OEM chips on a bare green PCB without a heat

The module uses Samsung, Micron or Hynix components mounted directly on the circuit board. The absence of a heat spreader reduces height for dense server chassis but relies on chassis airflow for cooling. The 288-pin RDIMM edge connector mates with standard DDR5 server sockets; the registered buffer adds minimal electrical load to the memory bus.

Questions about this item

Does the package include only the 128GB module or are extra parts like heat spreaders or cables supplied?

The package contains a single 128GB 288-Pin DDR5 RDIMM module; no heat spreader or additional accessories are included.

Should I choose the 4Rx4 CL40 1.1V version or look for a different rank or latency for the ThinkMate GPX-QH12-12E4-2GPU?

This module is built as 4Rx4 with CL40 latency at 1.1V, matching the specification for the compatible ThinkMate server.

What does the DDR5 4800 PC5-38400 rating mean for actual throughput in this server?

The DDR5 4800 rating indicates a PC5-38400 transfer rate; the module operates at CL40 with 4Rx4 organization under the server memory controller.
