When you buy a new computer, it comes loaded with stuff that you don’t need that can take up memory and make it slower, and this isn’t how a brand new machine should ordinarily behave.

Everybody wants a PC that delivers fast startup and runs operations at peak capacity, regardless of the brand or price of the machine. However, you cannot escape the slow computer issue because it will happen over time or even soon as you upload your files from a hard drive or other storage devices.

You could use Microsoft‘s Windows Refresh tool that purges all apps and leaves your computer in a pristine state, but there are other stronger tools that exist solely to help your computer get its groove back, and work as it has just undergone a factory reset.

How to clear RAM cache in Win 10?

Cached RAM (also known as SRAM) is closely linked to your CPU and it stores data frequently executed by it. The whole purpose is to provide accelerated and smooth access to commonly used programs by memory caching the recurrent instructions.

But sometimes, RAM cache can end up working against you rather than for you as these temporary files pile up and eventually slow down your PC or send CPU values through the roof when browsing the Internet.

Should I clear my RAM cache and if so, how often?

In order to make the most of your RAM and prevent your PC from becoming low on memory, occasional clean-ups are recommended. By reclaiming precious space on your hard drive, you will speed up your entire system and enjoy an overall fluid experience.

Here’s how to clean your RAM memory:

  1. Open the Settings app on your device.
  2. Next, go to System, and select Storage.
  3. Toggle the Storage Sense to on in order to get Windows to automatically delete irrelevant files.
  4. Alternatively, you can perform this task manually by selecting Clean now under Free up space now.

From uninstalling programs to deleting cached app backup files, CMD-based DNS flushing, and discarding stubborn temp files, there are countless possibilities.

But all of them require time and a fair amount of manual tweaking, which can easily become fastidious. We reckon the best method to keep your memory in pristine condition is to use dedicated RAM cleaner and optimizer tools.

Memory cleaners are apps that check your computer and fix the troublesome spots by defragmenting your hard drive, repairing the registry, and freeing up memory by getting rid of unnecessary and duplicate items on your computer – but there are those that go the extra mile.
