A-Tech 8GB DDR3 1866 ECC RDIMM 2Rx4 Cisco UCS-MR-1X082RZ-A

Compatible DDR3 ECC RDIMM for Cisco UCS

This 8GB DDR3 1866MHz ECC registered DIMM is a compatible replacement for Cisco part numbers UCS-MR-1X082RZ-A and 15-14069-01. It targets administrators upgrading or repairing supported Cisco UCS server and workstation platforms that require registered error-correcting memory. The module delivers 8GB capacity in a single stick.

Verify DDR3 RDIMM support and slot availability

Before ordering, confirm that your system accepts DDR3 registered DIMMs at 1.5V and has a free 240-pin DIMM slot. Check the platform's qualified vendor list or memory configurator for the exact Cisco part numbers listed above. Ensure the server BIOS and memory controller support CL13 latency at 1866MHz. Registered modules cannot be mixed with unbuffered memory in the same channel.

Sustained operation with ECC error correction

Under continuous workloads the registered buffer reduces electrical load on the memory controller while ECC circuitry detects and corrects single-bit errors in real time. Standard 1.5V DDR3 voltage and major-brand chipsets maintain stable signalling during extended uptime. The CL13 timing provides consistent latency for virtualisation, database and compute tasks that run for hours or days.
