256GB DDR4 Kit for Thinkmate Workstation

This NEMIX RAM kit delivers 256GB across eight 32GB DDR4 3200 UDIMM modules. It is built for the Thinkmate GPX-WS-540X1 workstation and runs at 1.2V with CL22 latency. The unbuffered non-ECC design suits desktop-class motherboards that accept 288-pin DDR4 memory.

Who this suits and who it does not

IT professionals upgrading a compatible Thinkmate workstation to the maximum supported capacity will benefit from the matched 8-module kit. Systems that require registered or ECC memory cannot use these modules. Buyers needing higher frequencies or lower latencies should look at a different specification.

Installation notes

The 288-pin UDIMM form factor fits standard DDR4 desktop slots and installs in minutes with the system powered off. Ensure all eight slots are populated identically for quad-channel operation. The most common issue is mixing this kit with existing modules of different rank or timing, which can prevent the system from posting.

Questions about this item

Does my THINKMATE GPX-WS-540X1 need eight free 288-pin DDR4 UDIMM slots for this 8x32GB kit?

Yes, the kit contains eight 32GB UDIMMs, so eight empty 288-pin DDR4 slots are required for full installation.

Can I keep my existing DDR4 3200 CL22 modules and add this 256GB kit without changing BIOS settings?

Mixing identical DDR4 3200 CL22 1.20V 2Rx8 modules usually works, but the motherboard will run all sticks at the slowest common timing.

How do I confirm the full 256GB is recognised at 3200 MT/s after fitting the eight modules?

Check the BIOS memory summary or Windows Task Manager — both should show 256GB total capacity and a speed of 3200 MT/s.
