ThinkMate VSX-R5 Server Memory

This NEMIX RAM kit provides 16 GB of DDR4 3200 ECC registered memory in a matched pair of 8 GB modules. It is built for ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations and servers that require registered DIMMs with error correction. The modules run at 1.20 V with CL22 latency and use a 1Rx8 organisation on 288-pin RDIMM form factor.

Compatibility and Use Cases

The kit suits administrators upgrading or populating the named ThinkMate platforms where registered ECC memory is mandatory for system stability. It is not for desktop PCs or consumer motherboards that accept only unbuffered non-ECC modules, nor for systems limited to lower-density ranks or different pin counts. Buyers needing higher capacities per slot or different speed grades should verify their platform documentation before ordering.

Decisive Specification

Registered ECC RDIMM architecture is the single specification that determines fit; the target workstations will not boot with unbuffered UDIMMs or non-ECC memory. This kit delivers exactly that registered ECC design at the required DDR4 3200 speed and 1.20 V voltage for the compatible ThinkMate models.

Questions about this item

Does the 288-pin DDR4 RDIMM form factor fit the ThinkMate VSX-R5-760S1 and VSX-R5-540RTP memory slots?

Yes, the kit uses the standard 288-pin DDR4 RDIMM form factor required by both ThinkMate workstation models.

What is the correct slot population order when installing the two 8 GB modules?

Install one module in each CPU memory channel following the motherboard manual’s channel map; the common mistake is placing both sticks in the same channel.

When should the registered ECC modules be replaced if correctable error counts rise?

Replace the kit when the system logs show increasing correctable ECC errors, indicating the Samsung, Micron or Hynix chips are degrading.
