Product: Server DDR4 16GB PC4-17000 Registered ECC Memory 2133MHz 1.2V Key benefits Designed for server environments where stability and data integrity matter. Registered ECC memory provides error detection and correction to reduce data errors during long periods of continuous operation. 2133 MHz data rate (PC4-17000) offers reliable, consistent performance for server workloads and multiuser systems. Low operating voltage of 1.2V helps reduce power draw and heat compared with higher-voltage modules. Compatibility and function Application type: Server memory. This module is a PC4 2Rx4 REG ECC DIMM and is not intended for standard desktop memory slots. Compatible with systems and motherboards that support registered ECC DDR4 modules. Confirm motherboard support before purchase; compatible with X99 platforms that explicitly support registered ECC DDR4. Module type: DDR4 16GB, PC4-17000 (DDR4 2133 MHz), registered ECC. Technical specifications Capacity: 16GB DDR4 Type: PC4 2Rx4 REG ECC Speed: 2133 MHz (PC4-17000) Voltage: 1.2V Rank/configuration: 2Rx4 Material: PCB Color: Random PCB color; specific color selection is not available What is included 1 x RAM module Only the RAM module is included. Other items shown in images are not included. Appearance and fit notes Due to production batch variations, the module appearance, color, and printing may differ between units. These cosmetic differences do not affect function. Color in photos may vary slightly because of lighting and display settings. Measurement tolerance: +/- 1 to 3 cm. Practical use scenarios Server memory upgrade: Replace or expand memory in a rack or tower server that requires registered ECC DDR4 to improve stability under sustained load. Virtualization host: Add memory to a virtualization server running multiple virtual machines where ECC protects against bit errors. Workstation with X99 support: Install in a workstation motherboard based on X99 that explicitly supports registered ECC DDR4 modules for compute and content creation tasks where data integrity is important. Installation and compatibility checklist Verify that your motherboard supports registered (buffered) ECC DDR4 modules and the 2133 MHz speed. This module is not compatible with standard unbuffered desktop DIMM slots unless the motherboard documentation explicitly states support for registered ECC modules. If in doubt, consult your motherboard or system documentation for supported memory types and maximum module size. Reliable server memory choice This registered ECC DDR4 16GB module is built for server-class systems requiring error correction and long-term reliability. Confirm platform compatibility before purchasing to ensure correct operation.
