Product overview Reliable DDR4 server memory module designed for servers and compatible workstation motherboards that support ECC registered memory. This module provides stable performance for multiuser, virtualization, and heavy compute workloads. Key benefits Error correction and stability: Registered ECC design (PC4 2Rx4 REG ECC) detects and corrects single-bit errors to reduce system crashes and data corruption in server environments. Steady performance: 16GB DDR4 capacity at 2133 MHz (PC4-17000) delivers consistent bandwidth for memory-intensive applications. Low operating voltage: 1.2V standard DDR4 power level helps maintain efficient operation and thermal performance. Broad compatibility within server class hardware: Suitable for server systems and motherboards that accept DDR4 registered ECC modules, including X99-compatible boards where ECC registered modules are supported. Specifications Memory type: DDR4 PC4 2Rx4 REG ECC Capacity: 16GB Frequency: 2133 MHz (PC4-17000) Voltage: 1.2V Rank/configuration: 2Rx4 (dual rank, x4 organization) Material: PCB PCB color: random; specific color cannot be selected Package contents: 1 x RAM module Compatibility and usage notes This is server memory. Not compatible with standard non-ECC desktop systems. Can be used on motherboards that explicitly support DDR4 registered ECC modules, including X99-compatible boards when those boards support registered ECC memory. Appearance, color, and printed markings may vary between production batches; these cosmetic differences do not affect function. Measurement tolerance: physical dimensions may vary plus or minus 1 to 3 cm. Only the RAM module is included. Other items shown in photos are not included. PC4 to DDR4 frequency reference PC4-17000 = DDR4 2133 MHz PC4-19200 = DDR4 2400 MHz PC4-21300 = DDR4 2666 MHz PC4-22400 = DDR4 2800 MHz PC4-24000 = DDR4 3000 MHz PC4-26400 = DDR4 3300 MHz PC4-26600 = DDR4 3333 MHz Typical applications Server memory upgrade or replacement in rack or tower servers running virtualization, databases, or caching services. High-stability workstations or compute nodes using X99-class motherboards that support registered ECC memory for content creation or scientific computing. Small data center racks or home lab servers where ECC registered memory is required for reliable long-term operation. Ordering reminders Confirm your server or motherboard supports DDR4 registered ECC modules before purchase. Color and labeling are supplied at random and cannot be chosen. Only one RAM module is provided per package.
