System-specific ECC RDIMM upgrade

This 32GB DDR5 4800 PC5-38400 CL40 2Rx8 288-pin 1.1V ECC Registered RDIMM is built for the Lenovo ThinkStation P5. It targets workstation and server environments that require registered memory with error correction. Standard desktop boards will not accept this module. It also cannot be mixed with unbuffered or load-reduced ECC DIMMs.

Verify registered ECC support and slot count

Before ordering, confirm the ThinkStation P5 motherboard accepts DDR5 registered ECC RDIMMs at 4800 speed and 1.1V. Check how many 288-pin slots are free and whether the BIOS recognises 2Rx8 organisation. Mixing this module with unbuffered or load-reduced memory is explicitly unsupported.

Single-module upgrade

The package contains one 32GB RDIMM that replaces Lenovo part numbers 4X71M22549, 4X77A77031 and 4X77A81440. OWC adds an advanced replacement programme and limited lifetime warranty with free technical support. No heat spreader, cables or software utilities are included.
