  • Registered 2Rx4 design ensures stability in multi-DIMM configs

Server-grade DDR3L ECC RDIMM

This 16 GB registered DDR3L module operates at 1600 MHz with CL11 latency and 1.35 V. It is built for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers that require ECC registered memory. Standard desktop systems cannot use this module.

Single-module 16 GB capacity

One 2Rx4 DIMM adds 16 GB of error-correcting memory to a compatible slot. The registered buffer reduces electrical load on the memory controller, allowing larger configurations within the platform limits. Workloads needing more than the platform maximum will require higher-density modules or additional servers.

DDR3L 1600 registered interface

The 240-pin DDR3L interface tops out at 1600 MHz (PC3L-12800) with registered signalling. Bandwidth and latency are fixed by this standard, so performance cannot exceed the platform memory-controller ceiling. Mixing with unbuffered or load-reduced DIMMs is not supported.

Questions about this item

Will this 16GB DDR3L 1600 CL11 2Rx4 1.35V ECC RDIMM work with existing 8GB DDR3L 1600 ECC RDIMM modules in a Cisco UCS B200 M3?

Mixing is only safe when the installed modules are also ECC Registered DDR3L 1600 CL11 1.35V RDIMMs; unbuffered or load-reduced DIMMs will prevent the server from booting.

How can I verify the 16GB DDR3L 1600 CL11 2Rx4 1.35V ECC RDIMM is recognised correctly after installation?

The Cisco UCS BIOS will display the new 16GB module at DDR3L 1600 speed with ECC Registered status and no memory errors during POST.

What is included with the OWC 16GB DDR3L 1600 CL11 2Rx4 240-pin 1.35V ECC RDIMM module?

The package contains a single 16GB DDR3L 1600 PC3L-12800 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM memory module.
