128GB DDR4 3200 ECC RDIMM

This 128GB registered DDR4 module targets IT professionals who maintain Thinkmate GPX workstations and need single-slot capacity for memory-intensive workloads. The ECC design protects data integrity in servers and high-end workstations where uptime is critical.

4Rx4 rank with CL22 latency

The module uses a 4Rx4 organisation at DDR4-3200 speed with CL22 timing. This rank configuration is the single specification that determines compatibility with the supported Thinkmate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 platforms.

1.2V operation without heat spreader

Running at 1.2V, the module draws standard DDR4 power and relies on chassis airflow for cooling since no heat spreader is fitted. Registered buffering reduces electrical load on the memory controller, helping maintain stable thermals in dense server configurations.

Questions about this item

What does the 3200 speed rating mean once the module is installed?

The module runs at DDR4 3200 (PC4-25600) speed, and the platform will operate it at that frequency when the memory controller supports it.

How does the 288-pin RDIMM interface affect what the system can use?

The 288-pin RDIMM form factor fits only DDR4 registered DIMM slots, so the motherboard must provide registered DDR4 memory channels.

What physical clearance does the 128GB 4Rx4 module need to fit?

The module is a standard-height 288-pin DDR4 RDIMM without a heat spreader, so it fits any slot that accepts full-height registered DIMMs.
