Why is unused RAM wasted RAM?
Random Access Memory in short RAM is a system memory typically used to store working data and machine codes in a volatile way. In the computing world, sufficient RAM makes sure the workflow is operating smoothly. If the system has less RAM size compared to what workflow needs then things will suffer from a huge performance loss. This is the reason why most of us have more than enough RAM on our computers than we needed.
But do you know, unused RAM is wasted RAM?
Yes, it is, if your workflow doesn’t demand more than 8 Gigs of RAM, there will be no benefit of having 16 Gigs of RAM. Instead, invest in other computer components that bottleneck a system like a superfast SSD/NVMe drive.
Why this bold statement?
Let’s take an example. Consider you have a bookshelf at home, and any book you want that is not on your bookshelf has to be fetched from a library to get them. Why is empty space on your bookshelf wasted space?
Because it makes more sense to have as many books as possible locally on your bookshelf so you are less likely to have to drive down to the library to get a book. The same applied to RAM too.
The more data are stored in RAM, the less chance of having to access a much slower storage system. That is why the operating system will often leave files in RAM when they are not being used until such time comes when another file is requested, and it will then clear out the space required for the new file that has been requested.
Even if you think that you are going to use the system for a long time, having too much RAM doesn’t benefit you at all. It will do nothing, eat power, and sit ideal all the time. Make 100% use of whatever you buy. Don’t just over-buy.
Even content creators and video gamers are unable to hit the 16 Gigs mark easily.
How to evaluate how much do I need?
Simple, just check your system status while doing all your activity at its full capacity. It will show you much memory is being used by the system while handling the workflow. If RAM is utilized way above 90% and the computer system lags a bit at this moment when you kick some more tasks then only upgrade to higher capacity RAM.
