The role of RAM on the PC is to maintain the processor-generated calculations, so that it can get you to where you need them now instead of doing the calculations again. However, there are many "urban legends" and "myths" about RAM that are nothing more than misconceptions from people who do not understand how it works, so in this article we will try to explain everything.
The different power and speed of RAM can be combined?
Generally, both laptops and desktop PCs come with a small amount of RAM, and one of the many “experts” ideas will tell you is that you should not combine different capabilities and / or memory speed because they present problems.
The truth is different. Can you mix different RAM capabilities? Yes, no problem. And speed? Also, although not very high performance, but you usually won't have any problems just because all RAM will work at slow module speed.
For example, you have a module running at 2400 MHz and you want to install one more to double the amount of RAM you have, but the new one runs at 3000 MHz. You will have no trouble doing it, only that both modules will run at 2400 Mhz. If you wanted both to work at 3000 MHz you would need to use the BIOS manually, and then you would have some stability issues.
Regarding the different capacity of RAM modules there is no problem as long as the motherboard supports those capabilities. For example, if you have a 4 GB module and install another 8 GB (12 GB in total), on a PC it would be like you have 4 + 4 GB running on one station and another 4 GB running on the same station.
Also, doesn't serve it very well, but from there on that you can't do it or that you will have problems there is a world away.
Need more RAM?
"This amount of RAM is more than enough for the programs you use and you don't need much" or "With 8 GB enough and too much waste" the repeated phrases we hear over and over again. Yes, you can have enough RAM for the programs you use, but that doesn't mean they can't work better if you have more RAM.
Having more RAM always helps, and this is so because of how programs and games are made. Many developers write their software in such a way that they request the operating system with a certain percentage of available RAM and not a certain amount, so the more RAM it is installed, the higher that percentage and the greater number of instructions will have direct access to the processor, so it will work better and faster.
The fact that you usually use 60% of your RAM just doesn't mean you don't need much, or rather, that you wouldn't be much better off if you had more RAM.
Because of how RAM memory management works in Windows, for example, a certain amount is stored for open or unused applications, but when a limit is reached, it starts "removing" RAM from the programs and limiting their functionality to render the app. in the new programs we are opening. If there is RAM available, this limit is extended remotely, with obvious benefits mentioned by this.
No, RAM capacity is not everything
You are certainly clear about how much RAM your PC has or, rather, how much skill you have. And many people think that simply, for example, 32 GB of RAM on their computer will work better than someone with just 8 GB, but the fact is that this is not always the case.
And that's not always the case because RAM memory performance is determined, not by its speed, but by its speed and duration. It is possible that with more RAM you have more power to have more open systems as we described in the previous article, but it won't work much faster.
In other words, if for example a person with 32 GB but working at 2400 Mhz would not have better performance than someone with only 8 GB but working at 4000 Mhz. So in short, no, power is not the most important thing, or at least not the "only" factor.
Should you release RAM to work better?
This is one of the most troubling and persistent myths about how RAM works on a PC, and it is a legacy of smartphones. Smartphones treat memory much differently than PCs, they are less efficient and, most importantly, and for many – especially Android – it is important to "drain or purge RAM" when performance is reduced.
On PC it is just the opposite. The fact that RAM is full (without reaching its limit, of course) means that there are many commands that a processor can use immediately without replication, so that performance can be much higher and save CPU work, delivering better performance.
Keep in mind that RAM is not like a hard disk, it is not used for storing objects but for temporary storage in processor work. If you have 8 GB of RAM, you always read and write data to it, and because it's data you don't want to store for future generations – unlike hard drives – it's the way it should work.
So, don’t listen to those promising plans do RAM well or pour it out. On a PC that not only works but doesn't work. Don't do it, actually. Having free space on the right disk is OK, in RAM it is not.
