Cisco 64GB DDR4-2666 TSV RDIMM PC4-21300 Quad-Rank x4 1.2V

Experience enterprise-grade memory performance designed to power Cisco server ecosystems with reliability and efficiency. The Cisco 64GB DDR4 SDRAM Memory Module delivers high-density memory capacity in a single module, enabling substantial improvements in virtualization, database operations, and large-scale analytics. Built for data centers and mission-critical workloads, this DDR4-2666 ECC Registered LRDIMM module combines robust error correction, streamlined reliability, and scalable performance to keep your Cisco servers responsive under demanding loads. Whether you’re consolidating virtual machines, accelerating in-memory databases, or supporting memory-intensive workloads, this module provides the speed, stability, and capacity you need to maintain service levels and deliver consistent business outcomes.

• High-density capacity for demanding workloads — 64 GB in a single module supports larger virtual machines, memory-tiering strategies, and dense server configurations, reducing the need for additional DIMMs and freeing up slots for other expansion.
• ECC and Registered for enterprise reliability — Error-Correcting Code (ECC) detects and corrects single-bit errors in real time, while the registered design (LRDIMM) lowers memory controller load, enabling stable performance in busy servers and virtualization hosts.
• DDR4-2666 speed with optimized timings — DDR4-2666 MHz memory delivers fast data access with CL22 timing, delivering lower latency for memory-bound workloads and smoother application responsiveness.
• Low-voltage efficiency — Operating at 1.20 V, this module balances performance with energy efficiency, helping data centers manage heat dissipation and power costs while maintaining peak throughput.
• Cisco-validated 288-pin LRDIMM form factor — Built to fit Cisco server platforms, ensuring compatibility, reliability, and scalable memory configurations within enterprise environments.

How to install Cisco 64GB DDR4 SDRAM Memory Module

• Power down the server completely and unplug all cables; ground yourself to prevent static discharge before handling memory.
• Open the server chassis and locate the memory slots appropriate for DDR4 LRDIMM installation, referring to the server’s manual for channel and slot organization.
• Align the 288-pin module with the slot notch, then firmly insert the memory into the socket until the retention clips snap into place on both ends.
• Install additional DIMMs in the recommended order or in the desired channel configuration, ensuring even seating and proper seating force to avoid partial contact.
• Power on the server, enter BIOS/UEFI, and verify that the 64 GB module is detected and appears in the memory summary; run a quick memory check and monitor for ECC error counters and DIMM status.

Frequently asked questions

• Is this memory compatible with Cisco servers? Yes. The Cisco 64GB DDR4 SDRAM Memory Module is designed for Cisco server environments, offering ECC Registered (LRDIMM) DDR4 memory for high-density systems. Always confirm model-specific compatibility in the Cisco memory QVL and the server’s hardware compatibility lists before installation.
• What workloads benefit most from 64 GB modules? Virtualization platforms (hypervisors), large databases, in-memory analytics, caching layers, and multi-user enterprise applications benefit from the increased capacity and bandwidth, enabling more VMs, faster data access, and improved overall system throughput.
• What is the operating voltage and speed? The module operates at 1.20 V and runs at DDR4-2666 MHz with CL22 timing, delivering a balance of speed and energy efficiency suitable for contemporary Cisco servers.
• What does ECC and Registered mean for reliability? ECC provides error detection and correction for single-bit errors, reducing the risk of data corruption, while the Registered (LRDIMM) design reduces electrical load on the memory controller, enabling higher capacities and more stable operation in dense server configurations.
• How should I validate memory installation? After installation, verify memory detection in BIOS/UEFI, run a memory diagnostic or vendor-approved test, and monitor memory health counters (ECC corrections, DIMM health) to ensure long-term reliability.
• Is there a warranty or support available? Warranty details are not specified in the product description; refer to the seller’s warranty policy and Cisco’s hardware support terms for coverage and service options.
