ThinkMate GPX-WS-540X1 Memory Kit

This NEMIX RAM kit delivers 64 GB across two 32 GB DDR4 UDIMM modules built for the ThinkMate GPX-WS-540X1 workstation. It runs at 3200 MT/s with CL22 latency at 1.2 V and uses 2Rx8 unbuffered non-ECC chips.

Ideal for capacity-bound workloads.

The dual-rank layout suits memory-intensive tasks such as virtualisation, large datasets or rendering on this specific platform. Buyers who need error-correcting code memory or registered modules for multi-socket servers should look elsewhere.

64 GB headroom for heavy multitasking

Two 288-pin DIMMs populate two slots and provide ample room for concurrent VMs or large application working sets. Systems requiring more than 64 GB or higher frequencies will need additional slots or a different memory configuration.

Questions about this item

Will this 288-pin DDR4 UDIMM kit install in my THINKMATE GPX-WS-540X1 workstation without any other hardware changes?

Yes, the kit is built for that workstation and uses the standard 288-pin DDR4 UDIMM form factor the system expects.

If I leave any original memory in the workstation, will these CL22 3200 modules run at their rated speed?

The system will clock all installed memory to the lowest common speed and timing, so mixed modules may run slower than 3200 CL22.

After seating both 32 GB sticks, how can I confirm the workstation sees the full 64 GB at 3200 MT/s?

Check the BIOS memory information or the operating system's memory details; they should report 64 GB total capacity and a 3200 MT/s data rate.
