16GB DDR3 ECC RDIMM for ThinkStation

This 16GB DDR3 1600 CL11 registered module uses a 2Rx4 organisation and runs at 1.5V. It is built as a 240-pin DIMM with ECC for error correction in workstation and server environments. The part number is 1R6D32R416GB and it replaces several Lenovo service numbers including 03T7754 and 0A89483.

Suits ThinkStation C30 D30 S30 upgrades

The module is validated for Lenovo ThinkStation C30, D30 and S30 systems that require registered ECC memory. It will not work in standard desktop computers that accept only unbuffered DIMMs, and it cannot be mixed with unbuffered modules in the same platform. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Single-module upgrade with lifetime support

The package contains one 16GB RDIMM and no additional cables, brackets or software media. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme, so a failed module can be swapped without extra cost. The memory is tested in-house to meet JEDEC and RoHS specifications.

Questions about this item

Does my Lenovo ThinkStation C30 need a registered DIMM slot to accept this 240-pin 1.5V ECC RDIMM?

Yes, the module is a 240-pin DDR3 ECC Registered RDIMM and requires a workstation or server board with registered DIMM slots.

Can I add this 16GB 2Rx4 CL11 stick alongside the original Lenovo 03T7754 unbuffered modules in my ThinkStation D30?

No, registered memory cannot be mixed with unbuffered memory; all installed modules must be ECC registered.

After installing the 16GB PC3-12800 module, how do I confirm the system sees the full capacity at 1600 MHz with ECC active?

Check BIOS or the OS memory report for 16 GB recognised, 1600 MHz speed, and ECC status reported as enabled.
