by Prime Tech Support

In the dynamic realm of Gaming, understanding RAM's (Random Access Memory) role is crucial. RAM, a high-speed bridge between your Gaming PC's CPU and GPU, ensures smooth gameplay by quickly accessing data.

Unlike long-term storage HDDs or SSDs, RAM is volatile and only holds data when powered. Crucial for Gaming, RAM affects load times, responsiveness, and FPS (Frames Per Second). However, there's a limit to RAM benefits, and this article explores the optimal amount needed for Gaming.

What is RAM and its purpose? 

"Random Access Memory" (RAM) is crucial for your Gaming PC's performance. RAM quickly provides data to your CPU and GPU. This is key for a smooth Gaming experience. Unlike HDDs (Hard Disks) or SSDs (Solid State Drives), RAM is used for immediate data access, not long-term storage.

RAM's main advantage is speed. It outperforms SSDs and is much quicker than HDDs. However, RAM is volatile. It loses its data when the power is off. So, it's not suited for storing data long-term like HDDs or SSDs.

For gamers, RAM ensures fast data access, crucial for Gaming smoothness. Using SSDs or HDDs for data swapping leads to slower loading, stuttering, and FPS (Frames Per Second) drops. FPS, the rate at which images are displayed, affects game fluidity. The human eye typically sees between 60 and 120 FPS. A higher FPS means a smoother Gaming experience.

However, the benefits of RAM have a limit. Adding more RAM than needed doesn't improve performance. Not enough RAM causes game slowdowns, lag, and crashes as the CPU struggles for data.

We often see problems caused by incorrect RAM setup or incompatible RAM and motherboards. These issues might not appear immediately, but they can cause system failures later. To avoid this, it's best to get professional help for RAM installation and configuration. Proper setup ensures optimal Gaming performance.

We'll guide you through various RAM types, their specifications, and uses.
