memory (RAM) is an essential component of your computer that stores the temporary data it needs to function. If your RAM is failing, it can lead to various issues, such as slowdowns, crashes, and even data loss. It is therefore important to test your RAM regularly to ensure that it is working properly.
Why test your RAM?
The main reason to test your computer's RAM is to diagnose and resolve stability and performance issues . If your computer frequently crashes, displays blue screens, or runs slowly, it may be due to faulty RAM.
It is also recommended to test your RAM when you install new RAM sticks . It's not uncommon for manufacturers to ship defective strips, and it's best to catch them early to avoid future problems.
Finally, testing your RAM frequently can help you prevent potential problems before they become critical. Faulty RAM can lead to data errors, frequent crashes, and general deterioration in your computer's performance . If you encounter this problem, here is how to proceed to boost the performance of your PC again !
