Frequently Asked Questions
What type of RAM does my system need?
Check your system’s specifications or use our RAM finder. Most modern laptops use DDR4 or DDR5 SO-DIMM, while desktops use UDIMM. Servers require ECC RDIMM or LRDIMM for data integrity.
Can I use any RAM in my system?
No. You must match the RAM type (DDR4 vs DDR5), form factor (SO-DIMM vs UDIMM), and speed. Using incompatible RAM can cause system instability or failure. Always verify compatibility before purchasing.
How much RAM do I need?
For basic office work: 8GB. For multitasking and video editing: 16GB. For professional workstations and servers: 32GB or more. Gaming benefits from 16-32GB depending on resolution and game engine.
Is brand really important?
Yes. Kingston, Crucial, Corsair, Samsung and SK Hynix are industry leaders with excellent warranty and support. They offer the best balance of reliability and value. Avoid unknown brands with no warranty.
What’s the difference between ECC and non-ECC RAM?
ECC (Error-Correcting Code) RAM detects and corrects memory errors automatically. It’s required for servers and workstations to prevent data corruption. Consumer laptops and desktops use standard non-ECC RAM.
How do I install RAM?
Power off and unplug your device. Locate the RAM slot (usually under a panel on laptops). Insert the new RAM at a 45-degree angle until it clicks into place. Screw the access panel back on and power up. See our installation guides for step-by-step photos.
