System-Specific 384GB DDR4 Kit

This NEMIX RAM kit delivers 384GB across six 64GB DDR4 3200 ECC RDIMM modules built for THINKMATE GPX workstations. Registered 4Rx4 organisation and CL22 timing at 1.2V suit server-grade workloads requiring error correction and high density. Modules use major OEM chips and carry no heat spreaders.

Upgrade from lower-capacity RDIMMs

The jump is worth it when your current registered DIMM population leaves empty slots and workloads hit capacity limits in virtualisation, rendering or large-database tasks. Adding this 6×64GB set fills a full bank with matched modules so the memory controller runs at the rated 3200 MT/s without down-clocking mixed ranks.

Verify slot count and qualified-vendor list

Confirm the workstation has six available 288-pin DDR4 RDIMM sockets and that the system BIOS recognises 4Rx4 64GB modules at PC4-25600. Cross-reference the THINKMATE GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 qualified-vendor list to ensure 384GB total capacity is supported before ordering.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the memory slots on a THINKMATE GPX-WS-540RTP workstation?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots on the THINKMATE GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations.

What is the correct way to install the six 64GB modules so the registered ECC memory initialises properly?

Populate all six slots following the motherboard's channel population order in the manual; the step often missed is seating each 288-pin module until both retention clips click.

When should the 4Rx4 registered DIMMs be replaced if ECC correctable errors start climbing?

Replace the kit when the system logs show a sustained rise in correctable error counts, indicating the 4Rx4 chips are degrading.
