Capacity & Compatibility

This 512GB kit contains four 128GB DDR5 4800 RDIMM modules built for the Thinkmate GPX-XS8-24S4-4GPU workstation. ECC and registered signalling protect data integrity in multi-socket server boards that require registered memory. The kit targets IT teams expanding memory capacity in compatible Thinkmate platforms.

Build & Connectors

Each module uses a standard 288-pin DDR5 RDIMM form factor without a heat spreader, relying on chassis airflow for cooling. 4Rx4 organisation and 1.1V operation match the electrical requirements of registered server motherboards. Installation follows normal DIMM-slot procedures; no special tools or cabling are needed.

Upgrade Context

The kit replaces lower-capacity DDR5 RDIMM sets or fills empty slots to reach the workstation's maximum supported memory. The jump is worthwhile when workloads such as virtualization, large datasets or GPU compute exceed the current memory ceiling. Buyers needing non-ECC unbuffered modules or a different pin count should look elsewhere.

Questions about this item

What DDR5 speed and CAS latency does this 512 GB kit run at?

The kit operates at DDR5 4800 MT/s with a CL40 latency, delivering PC5-38400 bandwidth across all four modules.

What physical slot and pin count do these modules require?

Each 128 GB module is a 288-pin DDR5 RDIMM designed for registered server DIMM sockets.

How are the four RDIMMs installed in the ThinkMate workstation?

Populate all four DIMM slots following the motherboard's population sequence; the step often missed is seating each module until both ejector clips click.
