Cisco 8GB DDR4-2133-MHz RDIMM – Server Memory

Upgrade your Cisco server with dependable, high-performance memory engineered for enterprise reliability. This 8GB DDR4 RDIMM module delivers 2133 MHz speed, registered ECC, and a single-rank/x4 configuration to boost stability, multitasking, and overall system throughput for data-intensive workloads.

• Server-grade DDR4 RDIMM memory: 8GB module (1 x 8GB) designed for Cisco servers, providing stable, error-checked performance in demanding data-center environments. The registered buffer helps manage memory capacity and timing with greater predictability under heavy load.
• DDR4-2133 MT/s speed (PC3-17000): Delivers faster data access and improved bandwidth for virtualization, databases, analytics, and memory-hungry applications. This speed tier balances performance and compatibility across a wide range of Cisco server platforms.
• Registered ECC for reliability: Error-Correcting Code (ECC) with registered buffering safeguards critical server workloads by detecting and correcting single-bit errors, reducing the risk of data corruption and unplanned downtime.
• Single rank, x4 configuration: Optimized memory organization that enhances channel interleaving and efficiency, offering a favorable balance between capacity, speed, and system scalability in multi-processor or multi-channel Cisco servers.
• Low voltage, energy-efficient operation: 1.20 V operating voltage minimizes power draw and heat generation in dense data-center racks, helping to maintain cooler temperatures and lower cooling costs while preserving performance headroom.

how to install Cisco 8GB DDR4-2133-MHz RDIMM

• Power down the server, unplug from power, and ground yourself to prevent static discharge before handling memory components.
• Open the chassis and locate the memory slots. Determine the correct DIMM channel and slot according to your server’s memory topology and ensure you follow any population guidelines for single-module upgrades.
• Hold the RDIMM by the edges and align the notch with the slot key. Insert the module at a slight angle (about 30 degrees) and ease it into place.
• Press down evenly along the module until the latches click and secure the DIMM in both retention clips. Confirm the module is seated firmly and fully.
• Power on and enter the system BIOS or UEFI to verify that the 8GB RDIMM is detected and recognized as ECC RAM. Run any available memory diagnostics to confirm stability and ECC functionality.
• Boot the operating system and validate that virtualization, databases, or other memory-intensive workloads see the upgraded capacity and improved responsiveness.

Frequently asked questions

• Q: What type of memory is this? A: It is a DDR4 SDRAM Registered ECC RDIMM module, 8GB capacity, 2133 MT/s, single rank with a x4 data width.
• Q: What does registered ECC mean? A: Registered buffering helps stabilize high-density memory configurations in servers, while ECC detects and corrects most single-bit errors to protect data integrity and uptime.
• Q: Is this memory compatible with all Cisco servers? A: It is designed for Cisco servers and other enterprise platforms that support DDR4 RDIMM modules. Always consult your server’s memory compatibility list or Cisco product documentation to confirm exact compatibility with your model and BIOS version.
• Q: What voltage does it operate at? A: 1.20 volts, which aids in energy efficiency while maintaining reliable performance for server workloads.
• Q: What are the benefits of upgrading to 8GB? A: Increasing memory capacity reduces paging, enables larger in-memory caches, improves virtualization density, accelerates databases and analytics tasks, and enhances overall system responsiveness under heavy load.
• Q: How can I verify the new memory is functioning properly? A: After installation, run memory diagnostics and check BIOS/UEFI memory reports. Look for ECC error reports, confirm correct detection of the 8GB module, and monitor system performance during typical workloads to ensure stability.
