Workstation memory kit

This OWC kit supplies 32 GB of DDR3 1333 ECC registered RDIMM memory in four 8 GB modules. It is built for Lenovo ThinkStation C20x and D20 workstations that require registered error-correcting memory.

Verify platform compatibility

Your system must accept 240-pin DDR3 registered DIMMs running at 1.5 V with CL9 latency. Registered ECC modules cannot be mixed with unbuffered memory, so confirm the workstation currently uses registered DIMMs before ordering.

Suits ThinkStation C20x and D20 upgrades

This kit fits owners of those specific workstations who need the full 32 GB capacity. Builders using standard desktop boards, consumer laptops or any platform that requires unbuffered memory should look elsewhere.
