OWC 8GB DDR3 ECC RDIMM for ThinkStation

This 8GB DDR3 1333 PC3-10600 CL9 registered ECC module is built for Lenovo ThinkStation C20x and D20 workstations. It delivers error-correcting registered memory for stable server and workstation workloads. The single 2Rx4 DIMM operates at 1.5V without a heat spreader. It replaces a long list of original Lenovo part numbers.

Check your ThinkStation model and memory type

Verify that your system is a ThinkStation C20x or D20 before ordering. This module is registered ECC memory and will not work in standard desktop computers. It also cannot be mixed with unbuffered DIMMs. Confirm your platform requires 240-pin DDR3 registered ECC at 1333 MT/s.

Fits ThinkStation C20x and D20 memory slots

Install this 240-pin RDIMM into a compatible slot to add 8GB of registered ECC capacity. It requires a platform that supports DDR3 1333 registered memory and cannot be used alongside unbuffered modules. The upgrade extends the life of existing workstation infrastructure. Matching capacity, speed and manufacturer across all DIMMs is recommended for optimal performance.

Questions about this item

Does the 240-pin DDR3 ECC RDIMM arrive as a single 8 GB stick or do I need to buy anything else to install it?

The upgrade consists of one 8 GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5 V ECC Registered DIMM. No additional parts are required for installation in a compatible slot.

My ThinkStation D20 has four DIMM slots — should I choose this 8 GB module or look for a different capacity?

This module provides 8 GB per stick. OWC recommends populating all slots with modules of the same capacity, speed and manufacturer, so select the capacity that matches your target total memory and available slots.

What does the PC3-10600 rating mean for real-world performance in my C20x workstation?

PC3-10600 indicates a peak transfer rate of 10 600 MB/s at DDR3 1333 MT/s with CL9 latency. The ECC registered design adds error correction and signal buffering for stable operation in workstation workloads.
