OWC 16GB DDR3L 1600 PC3L-12800 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM memory upgrade

SKU CH-2QHZ-DTMMH

16 GB DDR3L 1600 ECC registered RDIMM for Cisco UCS C200 M2 and C210 M2 servers

  • Capacity16GB
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes

Capacity 16GB

  • ECC registered design prevents data errors in servers
  • 16 GB capacity extends memory headroom for virtualization
  • 35 V DDR3L lowers power draw versus standard DDR3
  • 1600 MHz CL11 timing matches Cisco UCS C200 M2 and C210 M2 specs
  • Single 2Rx4 240-pin RDIMM simplifies upgrade to one slot

Targeted Server Memory

This 16GB DDR3L ECC Registered RDIMM is built for Cisco UCS C200 M2 and C210 M2 servers. It provides error-correcting, registered memory required by those workstation and server platforms. The module replaces Cisco part numbers UCSMR1X162RYA and UCSMR1X162RYARF. It is not compatible with standard desktop computers.

Build and Installation

The 240-pin DIMM operates at 1.35V without a heat spreader, fitting directly into the server memory slots. Registered buffering and 2Rx4 organisation place less electrical load on the memory controller, supporting stable operation in multi-module configurations. Mixing with unbuffered or load-reduced ECC memory is not supported.

DDR3L Platform Limits

DDR3L 1600 PC3L-12800 CL11 sets the maximum bandwidth and latency for this upgrade. Capacity per slot is fixed at 16GB, so total system memory depends on the number of available DIMM sockets in the Cisco chassis. Older DDR3-only systems cannot use this 1.35V module.

Questions about this item

What DDR3L speed and CAS latency does this 16GB module run at?

It operates at DDR3L 1600 (PC3L-12800) with a CL11 latency, the rated speed and timing for this registered ECC DIMM.

Will the 240-pin RDIMM fit the memory slots in a Cisco UCS C200 M2 or C210 M2 server?

Yes, the 240-pin registered form factor matches the DIMM slots on both the Cisco UCS C200 M2 and C210 M2 systems listed for this upgrade.

How is this ECC registered module installed, and what common mistake should be avoided?

Align the notch on the 240-pin DIMM with the slot key, press firmly until the retention clips lock, and do not mix it with unbuffered or load-reduced memory types.
