Speed:

RAM speed is measured in megahertz (MHz) and indicates how fast data can be read from or written to the RAM. Higher speeds can improve performance, especially in tasks that require quick data access.

CAS Latency (CL):

CAS Latency is the delay time between the read command and the moment the data is available. Lower CAS Latency values indicate faster performance. For example, CL14 is faster than CL16.

Voltage:

Different RAM modules operate at different voltages. DDR4, for example, typically operates at 1.2V, whereas DDR3 operates at 1.5V. Lower voltage RAM can reduce power consumption and heat generation.

Form Factor:

The most common form factor for desktop RAM is DIMM (Dual Inline Memory Module). DIMMs are available in various sizes, but the standard is 240-pin for DDR3 and 288-pin for DDR4.

4. Choosing the Right RAM:

Selecting the right RAM involves balancing capacity, speed, and compatibility with your system. Here are some factors to consider:

System Requirements:

Check your motherboard’s specifications to determine the type and maximum capacity of RAM it supports. This data is critical to guaranteeing consistency.
