Expandable Virtual RAM (Random Access Memory) will reserve a preset portion of your phone’s internal storage for storing temporary files, or RAM duties when the need for more RAM arises. RAM is important on most computing devices, given it determines how fast or slow your phone or even PC will work. The lesser the RAM, the slower the performance of the device.
Is Expandable Virtual RAM as good as more physical RAM?
No, performance-wise, actual physical RAM storage will always be faster and more reliable. This is because RAM speeds are much faster than internal storage speeds, even beating the speeds of UFS 3.1, one of the fastest internal storage options we can get on phones today.
When we use expandable virtual RAM, there is a lot of data being transferred from the RAM to the internal storage and back. This process is also happening at speeds slower than that of transfers happening entirely inside the RAM module since the comparatively slower internal storage is involved.
When you toggle the virtual memory feature on your smartphone, the phone actually allocates the amount of memory you’ve selected as virtual, but to allocate the space in the internal storage, you will have to restart the phone. For instance, the 6GB configuration of the Realme Narzo 30 5G supports an extension of 5GB, taking the total up to 11GB.
Now, let’s see how this feature actually works in real life. First things, first, if you extend RAM, you won’t see a bump in the amount of RAM used by the system 一 while the storage is allocated to Virtual RAM, your physical RAM will be of the same capacity.
This article clears up common misconceptions about expandable virtual RAM. It helps with multitasking but can’t match real physical RAM. For tasks like AI or real-time detection, every bit of performance counts. I found this guide on yolov8 real-time performance helpful, especially when paired with proper RAM management.
