Customer Questions & Answers
-
Question:
What systems is the OWC 8GB DDR4 RAM compatible with?
Answer: The OWC 8GB DDR4 RAM is specifically designed for compatibility with Synology DiskStation models DS1819 and DS1821. This compatibility ensures seamless integration, allowing users to utilize the enhanced memory capacity for improved performance. Upgrading to this RAM can help facilitate smoother operation of applications, media streaming, and file access within your NAS environment. -
Question:
What is the speed and type of the OWC 8GB DDR4 RAM?
Answer: This RAM operates at a speed of 2666MHz and follows the DDR4 standard. Being PC4-21300, it delivers optimal performance for demanding applications and multitasking scenarios. The ECC (Error-Correcting Code) feature further enhances data integrity by correcting memory errors, which is especially crucial in server environments where reliability is critical. -
Question:
Is this RAM unbuffered, and what does that imply?
Answer: Yes, the OWC 8GB DDR4 RAM is unbuffered, which means it does not contain additional registers to hold data. Unbuffered RAM is typically faster and offers lower latency, making it ideal for systems like NAS where speed is essential. However, this type of RAM is less scalable compared to registered DIMMs, which is a consideration for larger setups. -
Question:
What benefits does ECC RAM provide?
Answer: ECC RAM, like the OWC 8GB module, improves data accuracy by correcting minor errors that can occur during data storage and transfer. This feature is crucial in NAS applications where data integrity is paramount, helping to prevent system crashes and data corruption. Users operating critical applications or handling sensitive information will find ECC RAM particularly beneficial. -
Question:
How can I install the OWC 8GB DDR4 RAM in my NAS?
Answer: Installing the OWC 8GB DDR4 RAM requires opening the NAS chassis and locating the memory slots. Simply remove the existing RAM (if applicable) and insert the new module firmly into the slot. After installation, power on your NAS for it to automatically detect the new memory. This upgrade process enhances the overall performance of your network storage without needing professional assistance. -
Question:
What does SODIMM mean in the context of this RAM?
Answer: SODIMM stands for Small Outline Dual In-line Memory Module. This form factor is specifically designed for laptops and compact devices, including NAS systems. The compact size of SODIMMs makes them ideal for devices with limited space while still providing the necessary memory performance. Therefore, the OWC 8GB SODIMM RAM perfectly suits space-constrained NAS setups. -
Question:
Can I mix different RAM sizes with the OWC 8GB DDR4 RAM?
Answer: While it is technically possible to mix RAM sizes, it is not recommended. Mixing different memory sizes or specifications can lead to instability and decreased performance. For optimal results, it’s advisable to use identical RAM modules in terms of capacity, speed, and type. This ensures that the NAS operates smoothly and efficiently, maximizing its potential. -
Question:
Why is 1.2V important for this RAM?
Answer: The OWC 8GB DDR4 RAM operates at 1.2V, which is standard for DDR4 memory. This lower voltage allows for reduced power consumption compared to older DDR3 memory, contributing to overall energy savings and prolonged equipment life. Additionally, using 1.2V RAM improves thermal efficiency, which is beneficial for maintaining optimal operating conditions within your NAS. -
Question:
What can I expect in terms of performance gains after upgrading my NAS with this RAM?
Answer: Upgrading to the OWC 8GB DDR4 RAM can significantly enhance your NAS performance, especially in multi-user environments or when run demanding applications. You can expect faster data processing speeds, quicker access times for files, and improved responsiveness when running software or accessing media. This is particularly beneficial when multiple users stream or upload data simultaneously. -
Question:
Where can I buy OWC 8GB DDR4 RAM Compatible with Synology DiskStation DS1819 and DS1821 NAS System in Malta?
Answer: You can purchase the OWC 8GB DDR4 RAM from Ubuy in Malta. Ubuy is known for offering a diverse selection of tech products, including computer memory, ensuring that you receive high-quality components that meet your specific needs.
