ThinkMate GPX-WS Compatible Server Memory

This 48GB kit uses six 8GB DDR4 3200 registered ECC modules built for ThinkMate GPX-WS workstations. Each stick runs at 1.2V with CL22 latency and a 1Rx8 organisation. The registered design adds a buffer that helps the memory controller manage heavy multi-module loads in 288-pin slots.

Upgrading from unbuffered or non-ECC DIMMs

Systems that currently run standard desktop memory will gain error correction and registered signalling, which are required for stability in the listed GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 models. The jump is worth it when workloads demand data integrity across all 48GB and the motherboard specifies RDIMM population rules.

Tool-free DIMM installation with population rules

Modules seat vertically into 288-pin DDR4 slots and lock with the ejector tabs; no cables or drivers are involved. The usual mistake is ignoring the motherboard's slot-filling sequence for registered DIMMs, which can leave the system unbootable despite correct voltage and speed ratings.

Questions about this item

Does this 48 GB kit use standard 288-pin DDR4 RDIMM slots?

Yes, each 8 GB module is a 288-pin DDR4 RDIMM designed for registered server memory slots.

What is the correct order for populating the six modules in a ThinkMate GPX-WS workstation?

Install the 1Rx8 modules in the sequence specified by the system manual, typically filling matching channels first to enable registered ECC operation.

When should the registered ECC RDIMMs be replaced in a continuously running server?

Replace modules if ECC error counters rise, the system logs corrected memory errors, or diagnostic tests report failing ranks.
