Cisco Compatible UCS-MR-1X162RZ-A - 16GB DDR3 1866MHz PC3-14900/2R/x4/ 1.50V REG Dimm Memory Module OEM MFG

Upgrade your Cisco UCS infrastructure with confidence using the Cisco Compatible UCS-MR-1X162RZ-A. This 16GB DDR3 1866MHz RDIMM module is built to deliver consistent, enterprise-grade performance under heavy load, making it ideal for virtualization, large databases, memory-intensive apps, and multi-VM environments. Engineered as an OEM MFG product with Cisco compatibility in mind, it pairs seamlessly with UCS servers, ensuring stable operation, predictable latency, and robust error detection through ECC. With a 1.50V low-voltage design, the module reduces power consumption in dense data centers, helping you lower cooling costs while maintaining peak throughput. The included lifetime warranty further guarantees compatibility and support across your Cisco UCS deployments, giving IT teams the confidence to scale infrastructure without risk.

Designed to boost your server's memory capacity without compromising reliability, this UCS-MR-1X162RZ-A module supports demanding workloads—from virtualization platforms and in-memory caching to transactional databases and real-time analytics. When deployed in Cisco UCS environments, it contributes to balanced memory bandwidth across CPUs, enabling smoother operation under boom traffic and peak user activity. The ECC and registered (RDIMM) design guard against data corruption, reducing the need for costly error handling at the software layer and improving uptime for mission-critical applications. In short, it’s a high-performance, enterprise-grade RAM upgrade that aligns with Cisco's standards for compatibility, scalability, and long-term support.

Designed for mission-critical deployments, the memory module uses industrial-grade components tested to meet Cisco's stringent compatibility requirements. The RDIMM's registered design reduces signal noise and allows the memory controller to manage larger capacities more effectively, leading to improved stability during live migrations and high-transaction workloads. The ECC capability detects and corrects single-bit errors, preventing data corruption and reducing downtime. In virtualization environments, this translates to more VMs per host, more reliable live migration, and fewer memory-related bottlenecks during peak usage. The module also aligns with Cisco's recommended configurations for UCS to ensure consistent performance across blades and rack servers. The lifetime warranty provides ongoing assurance that the module will perform as expected, with replacement options available should a failure occur in the field.

How to install Cisco Compatible UCS-MR-1X162RZ-A

• Power down the server and unplug it from the power source. Ground yourself to prevent static discharge before handling memory.
• Open the server chassis and locate the memory slots appropriate for your Cisco UCS configuration. Always consult the Cisco UCS hardware guide for slot population and bandwidth guidelines before upgrading.
• If upgrading, remove any existing modules in the target banks by unlocking the retaining clips and gently pulling the module straight out.
• Carefully align the module with the slot’s notch and press straight down until the contact edge is fully seated and the retention clips click into place. Do not force the module; uneven seating can damage the connector.
• Install modules in recommended configurations to maximize interleaving and bandwidth as per Cisco's guidelines. If replacing multiple modules, reseat any previously removed modules according to the guide.
• Power on the server and enter the BIOS/UEFI or Cisco UCS Manager to verify that the RAM is recognized at 1866MHz with ECC enabled. If necessary, adjust memory timing to match the platform's supported profile.
• Run a memory diagnostic or stress test to confirm stability across all installed modules and to detect any potential ECC errors. Monitor for any BIOS or OS-level alerts during the test.
