Server ECC RDIMM kit

This OWC kit provides 32GB of DDR3L memory as four 8GB registered DIMMs. It is built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers that require ECC registered modules.

Check platform and slots

Verify that your server uses 240-pin DDR3L RDIMM slots and supports 1.35V registered memory with CL11 timing. This kit will not work in systems that only accept unbuffered or non-ECC modules.

Fits registered memory bays

The modules install directly into the server’s RDIMM slots without extra hardware. They free up capacity for larger workloads while matching the original Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G.

Questions about this item

What comes in the OWC 32GB kit and is anything else needed for installation?

The kit contains four 8GB DDR3L 1600 CL11 1Rx4 ECC Registered 240-pin RDIMM modules. No extra parts are required for installation in a compatible Dell PowerEdge server.

Should I choose this 32GB 4x8GB kit or a different capacity for my PowerEdge R720?

Choose this 4x8GB kit when you need 32GB total and want to populate four DIMM slots with matched modules for optimal channel balance on the R720.

What does the DDR3L 1600 PC3L-12800 rating mean once the modules are running in my R620?

The modules will operate at 1600MHz with CL11 latency at 1.35V, delivering PC3L-12800 bandwidth while providing ECC error correction and registered buffering for server stability.
