Form Factor

• Desktop Tower PCs: Typically use DIMM (Dual Inline Memory Module) form factor.
• Laptops: Use SODIMM (Small Outline DIMM) form factor.

Ensure you select the correct type based on your device. Desktop RAM will not fit in laptops and vice versa.

2. Frequency

• DDR4 RAM comes in various frequencies (measured in MHz), such as 2133 MHz, 2400 MHz, 2666 MHz, 3200 MHz, etc.
• Choose a frequency supported by your motherboard and CPU to avoid compatibility issues.

3. Voltage

• DDR4 operates at a standard 1.2V, which is efficient and provides better performance with less power consumption.

4. Compatibility

• Check if your PC or laptop’s motherboard supports DDR4 RAM, as some older models may only support DDR3.
• Ensure the maximum RAM capacity supported by your system before upgrading.

5. Brand & Warranty

• Opt for reliable brands like Corsair, Crucial, Kingston, G.Skill, or Samsung.
• Ensure it comes with a warranty, which is often provided for 3 to 10 years.

6. Upgradeability

• For desktops: Make sure your tower has enough slots and capacity to add 8GB of RAM.
• For laptops: You may need to replace existing modules if the slots are limited.
