Memory module Lenovo DDR4 16 GB 2133 MHz ECC

The Lenovo 46W0795 memory module provides 16 GB of DDR4 ECC RAM running at 2133 MHz with a CAS latency of 15 in a single-module configuration. Designed for systems that require error-correcting memory, this module focuses on stability and predictable performance for PC and server environments where data integrity and continuous operation are important.

Advantages

This 16 GB DDR4 ECC module improves system reliability by detecting and correcting single-bit memory errors, reducing the risk of data corruption in critical applications. The 2133 MHz clock rate combined with CAS latency 15 delivers balanced throughput and latency characteristics suitable for workstation and entry-level server workloads. Its single-module form factor makes it straightforward to install alongside existing memory to expand capacity and support multitasking and larger datasets.

Suitable for

• Workstations and entry-level servers requiring ECC memory
• Business PCs and systems handling databases, virtualization, or compute tasks
• Upgrading system memory to improve multitasking and application responsiveness

Key specifications

• Capacity: 16 GB
• Memory type: DDR4
• Clock speed: 2133 MHz
• ECC support: Yes (error-correcting code)
• CAS latency: 15
• Form factor: single module (DIMM compatible with supported motherboards)

How to use

Power down the system and disconnect it from the power source before installing the memory module. Open the system chassis according to the manufacturer's instructions, locate the appropriate memory slot compatible with DDR4 ECC DIMMs, and insert the module firmly until the retention clips engage. After reassembling the chassis and reconnecting power, enter the system BIOS or firmware to confirm the module is detected and verify ECC functionality if supported by the platform. Follow the system vendor guidelines for memory population rules and mixing modules.

Usage recommendations

For reliable operation, use this ECC module in systems that explicitly support DDR4 ECC memory and follow the motherboard or server manufacturer's recommendations for compatible memory configurations. When expanding memory capacity, install modules of the same type and speed where possible to maintain optimal performance and stability.
