Best Computer Memory (RAM) Buying Guide

Computer Memory (RAM) Buying Guide

Computer RAM

After the CPU and the GPU, the RAM is the third most important factor when it comes to the overall performance of a computer system. RAM is used to store data and codes that are used to run applications on our computer. These components are installed directly onto the motherboard and are usually situated near the central processing unit (CPU). If you are trying to figure out what to buy, here’s our guide on how to choose RAM.


Things to Consider before Buying Computer Memory 

CPU and OS limits 

As long as you have a 64-bit CPU that commonly supports up to 64 GB or 128 GB of RAM, you don’t need to worry about RAM limitations imposed by the CPU or the OS. 

Clock speed 

The clock speed can be defined as the number of times per second the RAM can access its memory. RAM speed is generally measured in megahertz (MHz). The clock speed of a RAM determines how fast it can process data, which reflects on the performance. Generally speaking, higher clock speed is always better, but capacity is always important than speed when it comes to gaming and editing videos.  

Motherboard and Slot count 

First of all, you need to find whether your motherboard supports DDR4 or DDR3. Search for system information, and then under System Summary, you’ll be able to see which motherboard you have in the system model field. Then, all you need to do is find that model on the manufacturer’s website and check all the information that you need in the spec sheet. 

Next, you need to check the number of RAM slots that can vary based on the form factor of the motherboard. Mini ITX motherboards only support two RAM slots, Whereas, ATX motherboards support four RAM slots. 

Memory usage 

The amount of Memory that your need depends entirely on your requirements and usage. If you have usual operations running on your computer, then go for 1 Kilobyte or 1 Megabyte. But if you are a gaming person with graphic games in your mind, then going for 1 terabyte is recommended.  

Timings and Latency 

Memory (DRAM) performance is all about the relationship between timings and latency. If your usual functions are taking time to load or the applications are slow, then you should consider going for higher memory.
