Memory module Lenovo 46W0795 16 GB (1x16 GB) DDR4 2133 MHz ECC CL15 for PC/Server

Lenovo 46W0795 16 GB (1x16 GB) DDR4 2133 MHz ECC CL15 is a single-module internal memory designed for compatible PCs and server platforms that require ECC support. The module uses DDR4 technology with a 2133 MHz data rate and CAS latency 15, offering a balance of capacity and stability for systems that need error-correcting memory. It is intended for system memory upgrades or replacements in workstations and servers where ECC RAM is specified.

Advantages

This 16 GB ECC DDR4 module provides error-correcting capability to detect and correct single-bit memory errors, improving system reliability in critical environments. With a 2133 MHz clock and CL15 latency it delivers consistent data throughput for applications that benefit from stable memory performance. The single-module format simplifies upgrades and allows expansion of system memory without replacing existing modules when slots are available.

Suitable for

• Server systems that require ECC memory for higher data integrity
• Workstations used for data analysis, virtualization, or content creation
• Upgrading or replacing existing RAM in compatible desktop and rack-mount systems
• Environments where uptime and error prevention are important

Key specifications

• Memory type: DDR4
• Capacity: 16 GB (single module)
• Speed: 2133 MHz
• CAS latency: CL15
• Error correction: ECC (Error-Correcting Code)
• Form factor: standard DIMM for PC/server motherboards

How to use

Power down the computer or server and disconnect it from the power source before installing the memory module. Open the chassis according to the manufacturer’s instructions, locate the appropriate memory slot that supports DDR4 ECC modules, and align the module with the slot keyed notch. Insert the module evenly until the retaining clips click into place. Reassemble the system, reconnect power, and verify that the BIOS or system firmware recognizes the new memory and that ECC functionality is enabled if required by the platform.

Usage recommendations

Install this module in matched pairs or per the server/vendor memory population guidelines when upgrading multi-channel configurations to ensure optimal performance and maintain ECC functionality. Consult your system documentation for supported memory densities, slot population order, and firmware settings to enable ECC support.
