Axiom 16GB DDR3-1866 ECC RDIMM for Cisco UCS-EZ7-16GB-MEM

SKU CH-H58J-T0TQY

16 GB DDR3-1866 ECC registered DIMM adds memory capacity to compatible Cisco servers

  • 16 GB capacity runs multiple applications simultaneously
  • DDR3 technology delivers up to 1866 MHz registered speed
  • ECC RDIMM design improves data integrity for heavy workloads
  • Minimal power consumption optimises performance and heat dissipation
  • 100% Cisco compatibility protects SMARTnet and system warranty

16GB DDR3-1866 ECC RDIMM

This 16GB DDR3-1866 ECC RDIMM is built for Cisco UCS servers that require registered memory with error correction. It suits administrators expanding capacity in supported Cisco systems such as the UCS-EZ7-16GB-MEM and UCS-MR-1X162RZ-A configurations.

Replaces smaller DDR3 RDIMMs

The module upgrades from lower-capacity DDR3 registered DIMMs when the platform supports 16GB densities at 1866 MHz. The jump is worth it when workloads need more simultaneous application headroom and the server memory controller accepts this speed and rank configuration.

DDR3 registered interface limits

DDR3 RDIMM topology caps bus speed at 1866 MHz and requires a registered signal buffer that adds one clock cycle of latency. Systems not qualified for 16GB registered modules or locked to lower DDR3 frequencies cannot use this part.

Questions about this item

Does this 16 GB DDR3 RDIMM fit a Cisco UCS server with part number UCS-EZ7-16GB-MEM?

Yes, the module is built for Cisco UCS systems and matches part numbers UCS-MR-1X162RZ-A and UCS-EZ7-16GB-MEM.

What is the correct way to seat this registered DIMM so the ECC function works?

Align the notch with the slot key, press straight down until both retention clips click, and verify the server BIOS reports 1866 MHz registered ECC operation.

When should I consider replacing this 16 GB DDR3-1866 ECC module?

Replace it if the system logs correctable ECC errors that increase over time, or if memory diagnostics report uncorrectable faults on this DIMM.
