Product identity

This is a single 32GB DDR5 ECC Registered RDIMM from OWC, rated at 4800 MT/s with CL40 latency and a 1.1V operating voltage. It uses a 288-pin form factor and a 2Rx8 rank configuration without a heat spreader. The module is validated for Lenovo ThinkStation P7 and PX workstations and replaces Lenovo part numbers 4X71M22549, 4X77A77031 and 4X77A81440.

Who it suits and who it does not

This memory is intended for workstations and servers that require registered ECC DDR5 modules. It will not function in standard desktop computers that accept only unbuffered memory, and it cannot be mixed with unbuffered or load-reduced ECC DIMMs. Buyers who need non-ECC or unbuffered modules should look at a different product line.

Deciding specification

The registered ECC design is the single factor that determines whether this module will work in a given system. Only platforms that explicitly support DDR5 RDIMM memory with a 2Rx8 organisation can use it.

商品問答

How much power does the 1.1V DDR5 module draw during sustained workloads?

It runs at 1.1 V, the standard DDR5 operating voltage, keeping power draw low even under continuous load in ThinkStation P7 or PX workstations.

Does my ThinkStation P7 or PX need a specific BIOS version or CPU to accept this ECC registered RDIMM?

The module is validated for Lenovo ThinkStation P7 and PX systems and replaces Lenovo part numbers 4X71M22549, 4X77A77031 and 4X77A81440.

Can I mix this 2Rx8 registered ECC DIMM with the unbuffered ECC sticks already in my workstation?

No — registered ECC memory cannot be mixed with unbuffered or load-reduced ECC modules; all slots must use registered DIMMs.
