System-specific ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR3 1333 registered DIMMs built for Lenovo ThinkStation C20x and D20 workstations. The modules run at PC3-10600 speed with CL9 latency and 1.5 V operation. ECC and registered signalling make them suitable for server-class workloads.

Installation notes and common issues

The 240-pin DDR3 form factor fits the designated slots in the listed ThinkStation models. ECC registered memory cannot be mixed with unbuffered modules, so all populated slots must use the same registered type. Verify the workstation model before installation because standard desktop boards will not accept these DIMMs.

Registered ECC requirement

The single decisive specification is the registered ECC design; the memory will only function in platforms that explicitly support registered DIMMs with error correction. Buyers whose systems require unbuffered non-ECC DDR3 cannot use this kit.

Perguntas sobre este artigo

How can I confirm the kit is running as ECC registered memory after installing it in a ThinkStation C20x?

Enter the system BIOS or use a hardware-info utility and verify that ECC is shown as active and the modules are reported as registered RDIMMs operating at 1333 MT/s with CL9 latency.

What does the 32 GB kit contain and are any extra parts required for installation?

The kit includes two 16 GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5 V ECC registered RDIMM modules; no additional components are needed for a compatible ThinkStation C20x or D20.

Should I choose this 2 × 16 GB kit or a different capacity for a ThinkStation D20 upgrade?

Select this 32 GB kit when you need two 16 GB modules to match the D20's registered ECC requirement and want to populate a pair of slots with 1333 MT/s CL9 RDIMMs.
