ThinkMate Workstation Upgrade

This 256GB kit targets IT professionals upgrading ThinkMate VSX-R5-760S1 or VSX-R5-540RTP workstations. Four 64GB registered ECC modules deliver server-grade stability for virtualization and database workloads. The DDR4 3200 specification matches the platform memory controller. Buyers needing non-ECC memory for consumer motherboards cannot use this kit.

Registered ECC DDR4 3200 CL22

Each module operates at 1.2V with a CAS latency of 22 and a 4Rx4 rank organization. The registered buffer reduces electrical load on the memory controller, allowing the full 256GB capacity across all slots. Systems that require unbuffered UDIMMs or a different latency profile will not post with these modules installed.

Four-Module Kit Ready to Install

The package contains four matched 64GB RDIMMs, eliminating the need to source individual sticks for a balanced population. No heat spreaders are fitted, so airflow in dense server chassis is unaffected. No additional software, cables or firmware tools are included in the box.

Questions about this item

What does 3200 MT/s mean once the kit is installed in a ThinkMate workstation?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency, delivering 256 GB total capacity across four 64 GB registered DIMMs.

What does the 288-pin RDIMM interface cap in practice?

The 288-pin DDR4 RDIMM form factor limits you to DDR4 memory controllers; it will not fit DDR5 or unbuffered UDIMM slots.

What physical space and power does the 4Rx4 kit need to fit and mount?

Each 64 GB stick is a standard-height 288-pin RDIMM drawing 1.2 V; four adjacent DIMM slots are required.
