Choosing the Right RAM
Match DDR generation (DDR4/DDR5), form factor (SO-DIMM for laptops, DIMM for desktops), speed rating, and maximum capacity to your device specs. Dual-channel (matched pairs) delivers better performance.

What to Look For When Buying
RAM Type and Generation
Modern systems use either DDR4 or DDR5 memory — they are physically different and not interchangeable. Check your NAS’s specifications or user manual to confirm which generation it requires. DDR5 offers higher bandwidth and improved power efficiency, while DDR4 remains widely available and more affordable.
Speed Rating (MHz)
RAM speed is measured in MHz (e.g., DDR4-3200 or DDR5-5600). Higher speeds can improve performance, but your system’s motherboard or chipset may cap the maximum supported speed. There’s no benefit to buying faster RAM than your system can use — it will simply downclock to the maximum supported rate.
Capacity
For everyday use and web browsing, 8GB is the minimum. For productivity, creative work, and modern gaming, 16GB is the sweet spot. Power users working with video editing, 3D rendering, or running virtual machines should consider 32GB or more. Always check your system’s maximum supported capacity before buying.
Single vs Dual Channel
If your system has two RAM slots, using two identical sticks (e.g., 2x8GB instead of 1x16GB) enables dual-channel mode, which can boost memory bandwidth by up to 20%. This is especially noticeable in gaming and media editing workloads.
Installation Tips
Before you begin, power down your system completely and disconnect the power cable. For laptops, remove the battery if possible. Ground yourself by touching a metal surface to discharge static electricity — static can permanently damage RAM modules.
Locate the RAM slots (usually accessible via a panel on the bottom of a laptop, or directly on the motherboard in a desktop). Release the retention clips on the existing modules, then insert the new RAM at a slight angle and press firmly until the clips snap into place. Power on and verify the new RAM is recognised in your system settings or BIOS.

How do I check what RAM is currently installed?
On Windows, open Task Manager (Ctrl+Shift+Esc), go to the Performance tab, and click Memory. This shows your current RAM capacity, speed, and how many slots are in use. On macOS, click the Apple menu, select About This Mac, then check the Memory section.
Can I mix different RAM brands?
Technically yes, but it’s not recommended. Mixing brands, speeds, or timings can cause instability or force all modules to run at the slowest stick’s speed. For best results, buy a matched kit from a single manufacturer.
Will upgrading RAM void my warranty?
For most laptops and desktops with user-accessible RAM slots, upgrading memory does not void the manufacturer’s warranty. However, always check your specific model’s warranty terms. Apple devices with soldered RAM cannot be upgraded after purchase.
How much RAM do I actually need?
For basic web browsing and office work: 8GB minimum. For multitasking and light gaming: 16GB recommended. For video editing, 3D rendering, or professional workloads: 32GB or more. Check your usage in Task Manager to see if you’re consistently using more than 80% of your current RAM.
What happens if I install incompatible RAM?
Your system will either fail to boot (no display, beeping sounds) or boot with only the compatible modules recognised. No permanent damage will occur — simply remove the incompatible RAM and replace it with the correct type.
