NEMIX RAM
Eight 128 GB DDR4 3200 ECC registered DIMMs deliver 1 TB of server-grade memory for ThinkMate workstations
This kit supplies 1 TB of registered DDR4 memory in eight 128 GB modules running at 3200 MT/s. It is built for ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations that require ECC RDIMM memory.
IT teams upgrading those exact ThinkMate models to the maximum supported capacity with 4Rx4 registered modules at 1.20 V will find a matched set. Builders using consumer motherboards, non-ECC platforms or systems limited to lower densities should look elsewhere.
The modules are 4Rx4 registered ECC RDIMMs with a CAS latency of 22 and operate at DDR4 3200 (PC4-25600). The workstation memory controller must support 4Rx4 registered DIMMs at this speed for the kit to function.

Yes, the 288-pin DDR4 RDIMM modules are built for the ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations.
Follow the motherboard manual for the exact channel sequence; the common mistake is placing modules in the wrong channel order, which prevents the system from posting.
No firmware updates are needed for the memory itself; ECC correction runs in hardware, and the modules carry a lifetime replacement warranty if a chip ever fails.
