Workstation ECC RDIMM Kit

This OWC kit supplies 32 GB of DDR3 1600 registered ECC memory in two 16 GB modules for Lenovo ThinkStation C30, D30 and S30 workstations. It is built for servers and workstations that require error-correcting registered DIMMs. It will not work in standard desktop computers that only accept unbuffered memory.

Simple DIMM Installation

Installation follows the usual 240-pin DIMM procedure: power down, open the chassis, align the notch and press until the retention clips lock. The modules have no heat spreader, so they fit tight slots without clearance issues. The only common mistake is mixing these registered DIMMs with unbuffered memory, which the platform does not support.

DDR3 1600 Platform Limits

The DDR3 1600 interface caps bandwidth at the PC3-12800 data rate and operates at 1.5 V. Registered ECC modules add a clock cycle of buffering, so latency is slightly higher than unbuffered equivalents at the same speed. Capacity is limited by the number of DIMM slots and the maximum density the ThinkStation memory controller recognises.

Questions about this item

How can I confirm the 32GB kit is running at DDR3 1600 CL11 after installation?

Enter the BIOS or use a system-information tool such as CPU-Z and verify the memory speed reads 1600 MHz with CAS latency 11.

What does the OWC 32GB upgrade kit contain and is anything else required?

The kit includes two 16GB 240-pin DDR3 ECC Registered RDIMM modules; no additional parts are needed for a compatible ThinkStation.

Which OWC DDR3 ECC Registered kit should I choose for a Lenovo ThinkStation C30, D30 or S30?

Select the 32GB (2 x 16GB) DDR3 1600 PC3-12800 CL11 2Rx4 1.5V kit — it replaces Lenovo part numbers 00FE676, 03T7754, 03T8399, 03X4378, 0A65734 and 0A89483.
