System-Specific Upgrade Kit

This NEMIX RAM kit delivers 64GB of DDR4 memory in a matched pair of 32GB UDIMMs. It is built for the THINKMATE VSX-R5-540X1 workstation. The modules run at 3200MHz with CL22 latency at 1.20V. They are non-ECC and unbuffered for standard desktop-class memory slots.

288-Pin UDIMM Form Factor

Each module uses the standard 288-pin DDR4 UDIMM connector and a 2Rx8 organisation. No heat spreader is fitted, keeping the profile low for tight workstation chassis. The chips are sourced from major OEM suppliers such as Samsung, Micron or Hynix. Installation follows the usual DIMM slot procedure described in the system manual.

Compatibility Check Required

Verify that the workstation has two free DDR4 UDIMM slots and that the motherboard accepts non-ECC unbuffered modules at 3200MHz. The system must support 2Rx8 density and 1.20V operation. Confirm the maximum supported capacity per slot in the THINKMATE documentation before ordering.
