32 GB DDR4 3200 ECC registered DIMM for Thinkmate VSX-R5-540W3 workstations
This 32 GB DDR4 3200 module is built for Thinkmate VSX-R5-540W3 workstations and servers. It adds error-correcting registered memory to systems that require data integrity under sustained loads. The single 2Rx8 rank fits one 288-pin slot and runs at 1.20 V. It targets IT professionals who need guaranteed compatibility in mission-critical environments.
The registered buffer reduces electrical load on the memory controller, allowing stable operation in dense configurations. Samsung, Micron or Hynix DRAM chips are used depending on supply, all stress tested under load before shipment. No heat spreader is fitted, so airflow in the chassis must handle thermal dissipation. The 288-pin RDIMM form factor matches the workstation's DIMM slots exactly.
Replacing unbuffered non-ECC modules with this registered ECC part adds single-bit correction and multi-bit detection for silent data corruption protection. The jump is worth it when workloads run long compute jobs, virtualisation clusters or ZFS storage pools that cannot tolerate bit flips. Systems already using registered ECC can add capacity without mixing ranks. Builders needing unbuffered UDIMMs or higher frequencies cannot use this module.

The module is rated at DDR4 3200 MT/s (PC4-25600); the system will operate it at that speed or at the highest speed the platform's memory controller supports.
Yes — it is a standard 288-pin DDR4 RDIMM with no heat spreader, designed to match the workstation's registered DIMM slots.
Power off the system, open the chassis, align the notch on the 288-pin RDIMM with the slot key, press firmly until the retention clips lock, then consult the owner's manual for any required BIOS configuration.
