OWC 8GB DDR3 ECC RDIMM

This module is an 8GB DDR3 1600 PC3-12800 CL11 registered ECC DIMM built for workstation and server platforms. It operates at 1.5V with a 1Rx4 organisation and uses a standard 240-pin form factor. The part number is 1R6D31R408GB.

Suits ThinkStation C30 D30 S30 owners

It fits Lenovo ThinkStation C30, D30 and S30 systems that require registered ECC memory and replaces Lenovo part 03X4325. Buyers with standard desktop boards that only accept unbuffered non-ECC modules cannot use this product. It also cannot be mixed with unbuffered memory in the same system.

Single 8GB module at DDR3 1600

One module provides 8GB of capacity at 1600 MT/s with CL11 latency. Registered ECC operation adds error correction and signal buffering for multi-module stability in supported workstations. Systems limited to lower speeds or unbuffered memory will not benefit from this module.

Questions about this item

Does this 240-pin DDR3 ECC RDIMM require a Lenovo ThinkStation C30, D30 or S30 workstation to operate?

Yes, the module is validated for the ThinkStation C30, D30 and S30 and is not compatible with standard desktop computers.

Can I mix this 1Rx4 registered DIMM with unbuffered memory already installed in my ThinkStation?

No, registered and unbuffered memory cannot be mixed; all slots must use registered ECC modules.

How do I verify the module is running at PC3-12800 CL11 after installation?

Check the BIOS or an OS tool such as CPU-Z; it should report DDR3-1600 at CL11 with ECC registered status.
