128GB DDR5 4800MHz ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 4800MHz CL40 registered DIMMs built for ThinkMate GPX-XS8-24S4-4GPU workstations. ECC and registered buffering protect data integrity in mission-critical server and workstation workloads.

288-pin DDR5 RDIMM form factor

Modules install directly into the workstation's 288-pin DDR5 RDIMM slots without adapters. Registered design reduces electrical load on the memory controller, freeing headroom for full population across all eight channels.

128GB capacity at 1.1V

The eight-module kit delivers 128GB of error-correcting memory for large datasets and virtualisation. CL40 latency and 4800MHz speed set the performance ceiling; workloads exceeding 128GB or requiring faster transfer rates will need a different configuration.

Questions about this item

Will the 4800 MHz DDR5 speed hold under continuous server workloads?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V, which is the rated JEDEC operating point for sustained use.

How much heat will eight registered DIMMs add to a fully loaded chassis?

These 1Rx8 RDIMMs have no heat spreader and operate at the standard 1.1 V DDR5 voltage, so thermal output matches baseline DDR5 registered memory.

Does the ThinkMate GPX-XS8-24S4-4GPU workstation require any specific BIOS setting for this 128 GB kit?

The kit is validated for the ThinkMate GPX-XS8-24S4-4GPU; install the eight 16 GB RDIMMs in the supported slots and the platform will detect the ECC registered configuration.
