This OWC 8GB DDR4 SO-DIMM upgrade directly addresses that limitation. By increasing your system's memory capacity, you enable smoother multitasking, faster file access, and improved responsiveness for all your storage and application needs. Unlike generic modules, OWC memory is tested rigorously to meet or exceed industry standards, ensuring compatibility and reliability for years of worry-free operation. This is a simple, cost-effective DIY upgrade that significantly enhances your NAS experience. **Who Should Upgrade & Who Should Consider Alternatives** — This 8GB DDR4 2666MHz SO-DIMM is ideal for Synology NAS users experiencing slow performance, limited multitasking, or seeking to expand their server's capabilities. If your NAS model supports DDR4 SO-DIMM and requires more RAM for running multiple applications or handling larger datasets, this upgrade is highly recommended. Users with existing 8GB modules of the same speed and type (DDR4 2666MHz SO-DIMM) might consider a matched pair for optimal performance, or a higher capacity module if their NAS supports it and their workload demands it. Ensure your specific Synology model is listed for compatibility before purchasing. ## How to use 1. Completely shut down your Synology NAS and unplug the power cord. Ground yourself by touching a metal object to discharge static electricity before handling internal components. — Power Down and Ground Yourself 2. Open your Synology NAS chassis according to its manual. Locate the existing RAM module(s). Gently release the clips holding the module in place and carefully slide it out of the slot. — Locate and Remove Existing RAM 3. Align the notch on the new OWC 8GB DDR4 SO-DIMM module with the slot. Insert the module at a slight angle and press down firmly until the clips snap into place, securing the module. — Install the New OWC RAM Module 4. Close the NAS chassis, reconnect the power cord, and power on the system. Your Synology NAS should recognize the new 8GB RAM module, and you can verify the upgrade in the system information. — Reassemble and Power On ## Product details | Field | Value | |---|---| | Compatible Devices | Synology NAS, Servers, Micro Servers | | Installation | DIY Project | | Warranty | Limited Lifetime Warranty with Advanced Replacement Program | | Brand | OWC | | Model Name | OWC 8GB DDR4 RAM | | Part Number | OWC2C6D41R808GB | | Memory Size | 8GB | | Memory Technology | DDR4 | | Memory Speed | 2666MHz | | Form Factor | SO-DIMM | | Number of Pins | 260 | | Voltage | 1.2V | | ECC | Yes | | CAS Latency | CL19 | | Rank | 1RX8 | | Module Count | 1 | | Package Weight | 3 oz | | Package Dimensions | 6 x 0.5 x 4 inches | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How to buy an original OWC 8GB DDR4 RAM module in India? To ensure you receive an original OWC 8GB DDR4 RAM module, purchase from CrowCrowCrow. We source directly from authorized US retailers, ensuring the product is factory-sealed and authentic. All customs duties and GST are included in the price, and your order is shipped via ExpressBox with tracking for secure delivery to your Indian pincode. ### What wattage power supply do I need for my PC? Add up the peak draw of your CPU and GPU, then add roughly 20–30% headroom for spikes and future upgrades. A mid-range gaming build with a single GPU commonly pairs well with a 650W–750W unit, while high-end multi-component systems may need 850W or more. The listing's wattage and connector count let you match it to your components. ### Will this power supply work with Indian mains electricity? Most current ATX/SFX units accept a universal 100–240V, 50/60Hz input, which covers India's 230V 50Hz supply — check the input specification on the label or listing. It connects via a standard IEC C13 power cord that is widely used in India, so a compatible cable is easy to source. ### Is OWC 8GB DDR4 RAM compatible with my Synology NAS? This 8GB DDR4 2666MHz SO-DIMM module is compatible with specific Synology NAS models including DS1522+, DS1618+, DS1621+, DS1821+, DS2419+, DS2422+, DS3622xs+, and others listed. Always verify your specific Synology model's RAM compatibility and maximum supported capacity before purchasing to ensure optimal performance. ### What is the difference between ECC and non-ECC RAM? ECC (Error-Correcting Code) RAM detects and corrects internal data corruption, making it more reliable for critical applications like servers and NAS devices. Non-ECC RAM does not have this error-checking capability. For data integrity in storage systems, ECC RAM is generally preferred. ### Can I mix different RAM modules in my Synology NAS? While Synology NAS systems can sometimes work with mixed RAM modules, it's always recommended to use modules of the same capacity, speed, and manufacturer for optimal performance and stability. OWC recommends matching DIMM specifications for the best results. ## Compliance No product-specific compliance warnings identified.
