32GB DDR3 ECC RDIMM for Lenovo ThinkStations

This 32GB DDR3 1600 module is a registered ECC DIMM built for Lenovo ThinkStation C30, D30 and S30 workstations. It runs at PC3-12800 with CL11 latency and 1.5V. The 4Rx4 organisation and 240-pin form factor match the qualified platforms exactly.

Workstation and server builders only

Buyers who need unbuffered memory for a standard desktop should look elsewhere. This module cannot be mixed with unbuffered DIMMs and will not function in consumer motherboards that lack registered ECC support. Systems requiring a different rank configuration or voltage are not compatible.

JEDEC and RoHS compliant single module

The stick ships alone with no extra cables, brackets or software. Compliance means it meets the official DDR3 electrical and environmental specs, so the upgrade is warranty-safe for the listed ThinkStations. No bundled utilities or installation media are included.

Questions about this item

Does my Lenovo ThinkStation need a 240-pin DDR3 slot that supports ECC registered memory for this 32GB module?

Yes, this module is a 240-pin DDR3 ECC registered RDIMM designed for ThinkStation C30, D30 and S30 workstations that accept registered ECC memory.

Can I install this 4Rx4 1.5V registered DIMM alongside any existing unbuffered DDR3 modules in my ThinkStation?

No, registered ECC memory cannot be mixed with unbuffered memory; all installed modules must be registered ECC for the system to function correctly.

How can I confirm the module is running at DDR3 1600 CL11 after installation?

Check the BIOS or UEFI memory information screen; it should report 1600 MHz speed, PC3-12800 rating and CL11 latency for the installed 32GB DIMM.
