OWC 64GB DDR3L ECC Registered kit

This OWC kit supplies 64GB of DDR3L memory in four 16GB registered DIMMs. It is built for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers that require ECC registered modules. The 240-pin form factor and 1.35V operation match the platform specifications exactly. Workstation and server administrators can use it to expand capacity or replace failed sticks.

DDR3L 1600 registered DIMM limits

DDR3L registered memory runs at 1600MHz with CL11 latency and cannot be mixed with unbuffered or load-reduced ECC types. The registered buffer adds one clock cycle of command delay, which the memory controller must support. Mixing ranks or voltages on the same channel will prevent the system from posting. Only platforms qualified for PC3L-12800 registered DIMMs can use this kit.

Registered ECC requirement decides fit

The single specification that determines compatibility is the registered ECC design. Standard desktop boards and consumer laptops accept only unbuffered non-ECC or unbuffered ECC modules, so they will not work with these DIMMs. Buyers must confirm their Cisco UCS model appears in the supported list before ordering.

Questions sur cet article

Should I buy the 64 GB kit as four 16 GB modules or look for a different capacity?

The kit supplies 64 GB total across four 16 GB RDIMMs, matching the maximum supported population for the listed Cisco UCS servers.

What does the 1600 MHz rating actually deliver inside a Cisco UCS B200 M3?

The modules run at DDR3L 1600 with CL11 latency at 1.35 V, providing the rated PC3L-12800 bandwidth when the platform memory controller operates at that speed.

Is the 240-pin DDR3L interface limited by the registered ECC design?

The registered ECC RDIMM format is required by the compatible Cisco UCS models; the 240-pin DDR3L interface carries the 1600 MT/s signal within that registered topology.
