16GB DDR3 ECC RDIMM for Lenovo servers

This 16GB DDR3 1333 PC3-10600 CL9 registered DIMM targets administrators upgrading Lenovo System x3550 M3, x3620 M3, x3630 M3, x3650 M3 or x3850 X5 servers. It operates at 1.5V with ECC and registered buffering for error-corrected workloads. The module uses a 240-pin form factor and 2Rx4 rank organisation. It is not compatible with standard desktop computers or unbuffered memory configurations.

Capacity and headroom

A single 16GB module adds substantial memory to supported platforms, allowing larger virtual-machine counts and bigger in-memory databases. The registered design and ECC protect data integrity under sustained load. Systems that require higher densities or faster speeds will exceed what this DDR3 1333 part can deliver. Mixing with unbuffered DIMMs is not supported.

Registered ECC requirement

The registered ECC specification is the decisive factor: only motherboards that accept registered DDR3 ECC RDIMMs can use this module. Desktop boards and consumer laptops lack the necessary buffer and error-correction circuitry. Verify the server model matches the listed Lenovo systems before purchase.

Questions about this item

Will this 16GB DDR3 1333 ECC RDIMM work alongside existing 8GB modules in my Lenovo System x3650 M3?

Mixing capacities is possible but OWC recommends matching capacity, speed and manufacturer for optimal performance; all modules must be DDR3 1333 PC3-10600 CL9 1.5V ECC Registered.

How can I verify the module is running at PC3-10600 CL9 after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 1333 MT/s, CL9 timings, 1.5 V and ECC Registered status.

Does the package include only the 16GB 2Rx4 RDIMM or are heat spreaders and cables supplied?

The box contains the single 16GB 240-pin DDR3 ECC Registered DIMM; no heat spreader or extra cables are included.
