Guide for Buyers


Because they are made with the finest quality components, branded RAM will always outperform local RAM. Furthermore, a brand would not cut corners on its goods or utilize low-quality materials. 

On the other hand, although a local brand RAM may be less expensive than a premium brand RAM, it will not function or endure as well owing to the usage of low-cost materials.

It is always advised that you never ignore the brand and instead go for a branded product for long-term advantages. 

Clock Speed in Memory

The speed of the RAM is the next consideration, and you may have heard the term “MHz” (MegaHertz) before: it refers to the number of cycles per second. 

3200MHz stands for 3.2 billion cycles per second in technical terms. And, for better performance, more cycles are required; however, this is not always the case, since certain models do not support high MHz. 

Furthermore, there are a few other factors that influence RAM performance, such as latency, CPU architecture, and so on. 


RAM modules aren’t intended to work with every system. There are a few things to consider before purchasing one that will operate on your computer. 

A basic rule of thumb is that if the RAM is compatible with your motherboard, it will function. Make sure you know what RAM your system supports before you choose RAM.

According to reports, there are six different kinds of memory technology:

SDR (Single Data Rate), DDR (Double Data Rate), DDR2 (Second Generation Data Rate), DDR3 (Third Generation Data Rate), DDR4 (Fourth Generation Data Rate), DDR5 (Fifth Generation Data Rate), DDR6 (Fifth Generation Data Rate), DDR7 (Fifth Generation Data Rate), DDR8 (Fifth Generation Data Rate), DDR9 (Fifth Generation Data Rate), DDR10 (Fif (Fifth Generation Data Rate).
