System-specific DDR4 upgrade for Thinkmate servers

This NEMIX RAM kit delivers 128 GB of DDR4 3200 ECC registered memory in two 64 GB modules. It is built for the Thinkmate VSX-R5-760S1 and VSX-R5-540RTP workstations and servers. The modules run at 1.20 V with CL22 latency and a 4Rx4 organisation.

Suited for IT teams expanding compatible Thinkmate

Administrators who need validated ECC registered DIMMs for these specific models can install this kit with confidence. Buyers who need unbuffered memory, a different speed grade, or modules for any other platform should look elsewhere.

128 GB total capacity in a 2 x 64 GB registered kit

The package provides two 288-pin RDIMMs rated at PC4-25600. This capacity and rank configuration is the deciding factor for matching the memory subsystem of the listed Thinkmate systems.

Questions about this item

Will the 4Rx4 registered modules require any firmware updates or special configuration on the Thinkmate VSX-R5-760S1?

The kit uses standard JEDEC DDR4 3200 registered ECC modules at 1.2 V. No firmware updates are mentioned; installation follows the system manual.

What limits sustained throughput on the VSX-R5-540RTP when both 64 GB sticks run at CL22?

The DDR4 3200 MT/s data rate and CL22 latency set the bandwidth ceiling; the registered buffer adds one cycle but ensures signal integrity at 128 GB.

How much extra heat and power do the two 1.2 V RDIMMs add during all-day operation?

Each module runs at 1.20 V without a heat spreader; total draw is low for DDR4 registered memory, and standard server airflow handles the thermals.
