DELL AA335286 memory module 16 GB 1 x 16 GB DDR4 288-pin DIMM ECC

The DELL DDR4 16 GB 2666 MHz ECC memory module is a 288-pin DIMM designed for workstation and server environments where data integrity and stable performance are important. This 16 GB DDR4 module operates at 2666 MHz and supports error-correcting code (ECC) to detect and correct single-bit memory errors, reducing the risk of data corruption during critical operations. With a standard 1.2 V operating voltage and a form factor compatible with systems that accept 288-pin DIMMs, the module provides a balanced combination of capacity and speed for multitasking and memory-intensive applications.

Advantages

The ECC functionality enhances system reliability by automatically detecting and correcting certain types of memory errors, which improves uptime and reduces the chance of silent data corruption. The 16 GB capacity increases available system memory for applications, virtual machines, and large datasets, while the 2666 MHz clock speed supports responsive performance in mixed workload environments. The 288-pin DIMM form factor and standard 1.2 V operation ensure compatibility with a wide range of servers and workstations that support DDR4 ECC memory.

Suitable for

• Server and workstation memory upgrades focused on stability and data integrity
• Virtualization hosts and hypervisors requiring reliable RAM for multiple VMs
• Database servers and business applications processing critical transactions
• Scientific computing and engineering applications with large memory footprints
• Systems used for long-running tasks where error correction reduces failure risk

Key specifications

• Capacity: 16 GB
• Memory type: DDR4
• Clock speed: 2666 MHz
• Form factor: 288-pin DIMM
• Operating voltage: 1.2 V
• ECC: error-correcting code support (single-bit correction)

How to use

Power down the system and disconnect it from mains power before installing the memory module. Open the server or workstation chassis according to the manufacturer’s instructions and locate the appropriate 288-pin DIMM slot that supports DDR4 ECC modules. Align the module with the slot notch, insert evenly until the retention clips engage, and ensure it is seated fully. After installation, close the chassis and reconnect power. On boot, verify that the system BIOS/UEFI recognizes the new memory and that ECC is enabled if required by the platform.

Recommendations

For optimal results, install memory modules in matched pairs or according to the motherboard vendor’s supported configurations. Use modules with the same capacity, speed, and voltage across channels when possible. Keep system firmware up to date to ensure proper ECC functionality and consult the server or motherboard compatibility list before purchase to confirm support for 2666 MHz DDR4 ECC modules.
