128GB DDR5 4800 ECC RDIMM for Thinkmate Workstation

This 128GB registered DIMM is built for the Thinkmate GPX-WS-740RTP7 workstation. It delivers DDR5 4800 speed with ECC protection for data integrity in server workloads. The module suits IT professionals who need validated, single-stick capacity upgrades.

Installing a single 288-pin RDIMM

Installation follows the standard DIMM slot procedure and typically takes minutes. The 4Rx4 organisation and 1.1V operation require a motherboard qualified for registered ECC DDR5. Mismatched rank counts or missing ECC support in the platform firmware will prevent boot.

DDR5 4800 registered ECC limits

The DDR5 4800 interface caps bandwidth at the PC5-38400 data rate with CL40 latency. Registered buffering adds one cycle of command delay but enables higher per-slot capacity. Systems not designed for registered ECC DDR5 cannot use this module.
