OWC 16GB DDR4 2133 ECC Registered RDIMM 2Rx4 CL15 1.2V 288-pin Cisco UCS M2814

SKU CH-AE0Y-Z5T8Y

16GB DDR4 2133 ECC registered RDIMM for Cisco UCS M2814 compute cartridge

  • Total capacity16 GB
  • Rated speedDDR4 2133 (PC4 17000)
  • CAS latencyCL15
  • Rated voltage1.2 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 16GB

  • ECC registered design protects data integrity in servers
  • 16 GB capacity expands memory for demanding workloads
  • DDR4 2133 speed with CL15 latency delivers responsive performance
  • 2 V operation reduces power draw and heat
  • Validated for Cisco UCS M2814 compute cartridge compatibility

Targeted Server Upgrade

This 16 GB DDR4 2133 ECC registered RDIMM is built for the Cisco UCS M2814 compute cartridge. It replaces Cisco part numbers UCSMR1X162RUA and UCSMR1X162RUG with a single 2Rx4 module running at 1.2 V and CL15 latency.

Steady-State Reliability

Registered buffering and on-die ECC correct single-bit errors in real time, preventing data corruption during continuous workloads. The 2Rx4 organisation spreads electrical load across ranks, helping the memory controller maintain signal integrity at the rated 2133 MT/s speed without throttling.

Direct OEM Replacement

The module slots into existing M2814 cartridges without firmware changes or mixed-rank complications. It is not compatible with standard desktop boards, unbuffered DIMM slots or load-reduced memory populations. Buyers needing higher densities per slot or faster JEDEC speeds must select a different part number.

Questions about this item

How much power does this 1.2V DDR4 ECC RDIMM draw when the Cisco UCS M2814 runs continuously?

The module operates at 1.2V, the standard DDR4 voltage, so power draw stays within JEDEC limits for registered ECC DIMMs under sustained server workloads.

What must the Cisco UCS M2814 Compute Cartridge already have to accept this 288-pin registered DIMM?

The cartridge needs an available 288-pin DDR4 RDIMM slot and a memory controller that supports ECC registered modules; unbuffered or load-reduced DIMMs cannot be mixed with this part.

Can this 2Rx4 CL15 module sit beside older Cisco UCS memory such as part numbers UCSMR1X162RUA or UCSMR1X162RUG?

Yes, it replaces those exact Cisco part numbers, so it will operate alongside them provided all installed DIMMs share the same registered ECC specification.
