🔧 Extend RAM on Infinix Phones: Complete Model List, How to Enable Fusimem, Functions, Advantages, Disadvantages, and Its Impact on Gaming

📌 Introduction

Over the past few years, Infinix smartphones have become increasingly popular in the entry-level to mid-range segments. One feature that is frequently discussed by users is Extend RAM, which in the Infinix system is known as Fusimem, RAM Plus, or Virtual RAM.

Interestingly, this feature is not only available on the latest Infinix devices but has also appeared on several older models after XOS system updates. This situation raises many questions, especially among gaming enthusiasts:

does Extend RAM really help performance, which Infinix models support it, and how can it be enabled correctly?

🔍 What Is Extend RAM on Infinix Phones?

Extend RAM is a system feature that allows Infinix phones to use a portion of internal storage as virtual RAM. When physical RAM becomes full, the system shifts part of the application workload to this storage space.

Important points to understand:

• Extend RAM is not an addition of physical RAM
• It does not change hardware specifications
• Its speed is slower than real RAM

However, in certain scenarios—especially multitasking—this feature can help keep applications running in the background.

🔚 Conclusion

Extend RAM on Infinix phones is a functional additional feature, especially for maintaining system stability and multitasking. However, it is not an instant solution for improving heavy gaming performance.

By understanding how it works, its functions, and its limitations—including its impact on gaming—users can utilize Extend RAM more wisely and effectively. Choosing the right capacity and matching it with device conditions is the key to ensuring that Fusimem truly provides benefits, rather than just adding numbers to specifications.
