Lenovo ThinkStation ECC RDIMM upgrade

This OWC 16 GB DDR4 2133 MHz ECC registered RDIMM is built for Lenovo ThinkStation P500, P700 and P900 workstations. It delivers 16 GB of PC4-17000 CL15 memory at 1.2 V in a 288-pin 2Rx4 form factor. The module targets professionals who need error-correcting registered memory for stable server-class workloads.

Check motherboard slots and memory rules

Before ordering, confirm your ThinkStation has free 288-pin DDR4 RDIMM slots and that the system BIOS supports registered ECC modules. This memory cannot be mixed with unbuffered DIMMs, so all installed sticks must share the same registered ECC type. Verify the maximum supported capacity per slot and total system limit in the workstation documentation.

Replaces Lenovo 46W0795 46W0796 4X70F28590

This module directly replaces the listed Lenovo part numbers when expanding or refreshing memory in compatible ThinkStations. The upgrade is worthwhile when ECC registered capacity is needed for data-integrity tasks or when the workstation currently runs with unbuffered memory that the platform does not support. Buyers who need unbuffered desktop memory or higher-frequency modules should look elsewhere.
