ECC Registered RDIMM for Lenovo servers

This OWC module is an 8 GB DDR3 1333 ECC registered DIMM built for Lenovo System x3550 M3 R4 and x3650 M2 servers. It targets administrators who need reliable, error-correcting memory to keep workloads stable in production environments.

8 GB at PC3-10600 CL9 with 2Rx4 organisation

The single stick delivers 8 GB of capacity at 1333 MT/s and CL9 latency, running at the standard 1.5 V. Registered signalling and ECC protect data integrity, but the module will not work in standard desktop boards and cannot be mixed with unbuffered DIMMs.

240-pin DDR3 form factor for matched upgrades

The 240-pin RDIMM plugs directly into the supported Lenovo platforms and requires identical capacity, speed and manufacturer for optimal performance. It replaces a long list of Lenovo part numbers, letting you extend existing infrastructure without introducing mismatched modules.

Questions about this item

Will this 240-pin DDR3 1333 ECC RDIMM run alongside my existing 1333 MHz registered modules in the Lenovo System x3550 M3?

Yes, provided the installed DIMMs are also DDR3 1333 ECC registered with matching 1.5 V voltage and 2Rx4 rank; mixing registered with unbuffered memory is not supported.

How can I confirm the module is detected at the correct 1333 MT/s speed and ECC function after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 1333 MHz with ECC enabled; the server POST screen will also report the total ECC capacity.

Does the package include only the 8 GB RDIMM, or are any tools or additional parts supplied?

The box contains the single 8 GB DDR3 1333 ECC registered RDIMM; no tools, heat spreader or extra components are included.
