D4ES01-8G Synology 8GB PC4-21300 DDR4-2666MHz ECC CL19 260-Pin So Dimm
D4ES01-8G Overview
The Synology D4ES01-8G is a specialized, enterprise-grade 8GB DDR4 small-form-factor memory module engineered primarily for high-reliability network-attached storage (NAS) deployment. Operating at a native frequency of 2666MHz (PC4-21300), it is designed to extend system caching boundaries, accelerate internal database lookups, and ensure seamless performance during parallel file transfers, automated containerized workflows, and steady data-entry operations.
A defining characteristic of this module is its ECC Unbuffered (SODIMM) architecture packaged into a 260-pin small-form-factor design. Unlike mainstream laptop memory, this module features built-in Error Correction Code (ECC) circuitry to detect and fix single-bit errors in real time.

728629-B21 Overview
Is finding reliable DRAM memory for your HP ProLiant Server series in your data center a major challenge? When you choose HP SmartMemory you get the same high quality, reliability, and confidence that come with your HP ProLiant Gen9 Server series. DRAM quality and reliability are more important now than ever. Industry trends such as server virtualization, cloud computing, the use of large database applications, and high-performance computing have all increased the need for higher capacity memory with greater reliability and uptime. HP SmartMemory is a unique technology introduced in HP ProLiant Gen8 Servers that unlocks certain features available only with HP Qualified Server memory in Gen9 servers also. HP SmartMemory enables ProLiant Gen9 systems to reliably identify and verify whether installed memory has passed the rigorous HP qualification and testing processes. And because the memory is authenticated, you can enable extended memory performance features through the system ROM.
