ThinkMate Workstation Compatibility

This 128 GB DDR4 3200 kit is validated for the ThinkMate VSX-R5-540W3 workstation. It arrives as two 64 GB registered DIMMs with ECC and a CAS latency of 22. The modules operate at 1.2 V and use a 288-pin RDIMM form factor.

Registered ECC Architecture

Registered buffering and ECC reduce electrical load on the memory controller and correct single-bit errors, which helps stability under sustained server workloads. The 4Rx4 organisation packs 64 GB into each DIMM, freeing additional slots for future expansion. No heat spreaders are fitted, so airflow in dense chassis is unimpeded.

For ECC Workstation Builds

Suited to IT professionals upgrading or populating the specified ThinkMate platform with maximum registered ECC capacity. Not intended for consumer desktop boards that lack registered DIMM support, for systems requiring unbuffered memory, or for buyers who need speeds above DDR4 3200.

Questions about this item

How many ranks per module will the memory controller see with this 4Rx4 kit?

Each 64 GB module is 4Rx4 so the controller sees four ranks per DIMM, eight ranks total across the pair.

What is the operating voltage and registered buffer status for continuous server workloads?

The modules run at 1.20 V and are registered ECC RDIMMs designed for sustained server operation.

Which workstation model must the buyer already own for guaranteed compatibility?

This kit is validated for the THINKMATE VSX-R5-540W3 workstation.
