System-Specific DDR3 Upgrade

This 16 GB DDR3 ECC Registered DIMM is built for Lenovo ThinkStation C20x and D20 workstations. It targets administrators extending the service life of existing server-class hardware or adding capacity to supported platforms. The module will not work in standard desktop PCs and cannot be mixed with unbuffered memory.

240-Pin Registered Form Factor

The 240-pin RDIMM design fits the proprietary workstation slots used by the listed ThinkStation models. Registered signalling reduces electrical load on the memory controller, allowing larger populations of modules per channel. No heat spreader is fitted, so airflow in the original chassis remains unchanged.

16 GB DDR3 1333 CL9 Capacity

A single 16 GB module running at DDR3 1333 (PC3-10600) with CL9 latency and 1.5 V operation delivers the maximum density available in this registered format. Buyers needing higher total memory must populate additional slots with identical specification DIMMs; systems requiring unbuffered or non-ECC memory are not supported.
