  • Validated replacement for Cisco UCSMR1X082RYA part number

Targeted server upgrade

This OWC 8GB DDR3L 1600 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM is built for Cisco UCS B200 M3 B22 M3 B420 M3 C22 M3 C220 M3 systems. It replaces Cisco part number UCSMR1X082RYA and fits workstation, server, NAS or router platforms that require registered ECC memory. Buyers who need unbuffered or load-reduced DIMMs cannot use this module.

DDR3L interface limits

The DDR3L 1600 PC3L-12800 standard tops out at 1600 MT/s and 1.35V operation. Registered buffering adds one clock cycle of latency but allows higher capacities per channel than unbuffered DDR3L. Systems that only accept 1.5V DDR3 or that lack ECC support will not post with this module installed.

Build and daily handling

A bare green PCB without a heat spreader keeps the module low-profile for dense blade chassis. Gold-edge 240-pin connectors seat firmly in standard DDR3 DIMM sockets and the JEDEC-compliant, RoHS-compliant assembly is validated in OWC's in-house lab. The registered design means each stick presents a single electrical load to the memory controller.

Questions about this item

Should I choose the 8GB module or a different capacity for my Cisco UCS server?

This listing is for a single 8GB DDR3L 1600 CL11 2Rx4 registered DIMM. Add multiple modules to reach the total capacity your Cisco UCS model supports.

What does the 1600MHz CL11 rating deliver in a Cisco UCS B200 M3 or C220 M3?

The module runs at DDR3L 1600 (PC3L-12800) with CAS latency 11, providing ECC error correction and registered buffering for stable server operation.

Is the 240-pin DDR3L 1.35V interface compatible with standard desktop DDR3 slots?

No. This 240-pin DDR3L ECC registered RDIMM requires a server or workstation platform that supports registered memory; it will not work in standard desktop boards.
