Let's talk about RAM (by Random-access memory). Upgrade your computer or purchase a new one? Difficult if you follow the technology and you do not think about your wallet. But if we talk only about RAM, a simple upgrade is not a matter. But here is another question:
Is it enough to increase RAM or would it be better to add faster RAM? This question is not as simple as it may seem.
Why you need RAM
You need to be sure that you have enough RAM to cover the general requirements of your computer. If you are not sure how much RAM you need, do not worry, we'll look at it below.
In short, think of RAM as a short-term memory used by your computer's processor to store the files it needs for quick and frequent access. Using this space allows your machine to respond immediately. This may sound "a little", but waiting even just a few seconds for each process makes using the computer unbearable.
When your computer tries to run applications, more RAM is needed. To run an application RAM is used for faster access to your hard drive, where applications are stored.
Cases where you need more RAM.
If your computer is old, it may have had enough RAM (when you purchased it), but over the years it no longer meets the requirements of today. It's also very likely that RAM does not get you if you buy a cheap computer. These devices tend to be fast at first, but as you load the machine with applications, others start to lose performance.
The difference between capacity and speed
The capacity of RAM can be measured in megabytes (MB), gigabytes (GB) or terabyte (TB). Increasing the size of RAM reduces the likelihood of using your hard drive to store temporary files. But when you have enough RAM that meets your needs, you get to a point where adding more is not the best way to improve speed. It will do much more to add RAM that is faster than your RAM you already have, even if it's in the same GB, MB, or TB.
There are a few measurements that determine the speed of your RAM. The frequency affects the maximum bandwidth, that is, how much data can be transferred to and from your memory each time. Delay affects how fast RAM can respond to a request.
Frequency is measured in megahertz (MHz) and of course you need the largest number. The delay appears as a series of numbers (like 3-3-3-6) and you want to be lower.
Once your capacity needs are met, increasing frequency and slowing down can give you a much better result than having more RAM.
How (or How Fast) RAM Do You Need?
Having too much RAM is useful if you use your computer for demanding tasks such as professional video or audio editing. Then, 8 to 16 GB RAM should be enough to handle many professional applications at the same time. You probably will not need to think about upgrading your memory for several years.
If you are a gamer, 16 GB is good, as 8 GB will be needed for most games. The jump to 32 GB will probably be superfluous. You can get better results if you use faster RAM.
Regardless of how you use your computer, speed will not be affected if your motherboard is not as fast as your RAM you are wearing. A motherboard on 1333 MHz will limit the 2000 MHz RAM to 1333 MHz.
There are cases where more RAM is required, but those who manage servers are facing them. The requirements of running apps, games and webpages are simply not so high as to justify computers with huge amounts of RAM.
How to upgrade your RAM?
Are you trying to upgrade? How many RAM slots does your machine have? This can determine how much RAM you can wear. There are DDR2 sticks with maximum capacity of 4 GB. DDR3 sticks can reach up to 8 GB. If you have two RAM memory slots, with 2 DDR3 sticks of 8GB, you will have 16 GB RAM. Unless your machine can manage DDR4 of 16 GB.
If your computer has two slots but only one RAM stick try adding a second stick instead of replacing the existing one. Dual channel platforms can greatly improve the performance of your computer.
However, if you start building a computer from scratch and think of a 8 GB stick against two 4 GB sticks, go straight to the first one. This leaves you with the option to add a second stick to reach 16 GB in the future instead of having to replace both of you. The difference between one and two sticks is not so great that you can observe it.
If you want to upgrade to RAM, but all your jacks are already at their maximum capacity, then your only choice is to buy faster sticks.
What's most important: capacity or speed?
The capacity of the RAM that you have is more important as a point. After that, you start experiencing reduced returns. Switching to 8 GB is not really necessary unless you are a demanding user.
If you are a very demanding user, there is no clear answer. In some cases, you can add more RAM memory. In other cases, you can get better results with higher frequency and less delay. You may also notice differences depending on the operating system you are running.
