64GB DDR5 kit for Thinkmate workstations

This 64GB kit contains four 16GB DDR5 UDIMMs built for the Thinkmate VSX-R5-340V12 workstation. It targets professionals who need a validated memory upgrade for that specific platform without mixing modules.

Unbuffered non-ECC modules

Each stick is an unbuffered non-ECC UDIMM using major OEM chips from Samsung Micron or Hynix. The 288-pin DDR5 form factor fits the workstation's desktop DIMM slots and the absence of a heat spreader keeps the profile low for dense configurations.

DDR5 4800 CL40 at 1.1V decides compatibility

The kit runs at DDR5 4800 (PC5-38400) with CAS latency 40 at 1.1V in a 1Rx8 organisation. Buyers whose system requires ECC registered memory or a different speed grade cannot use this kit.
