You wonder why My PC does not recognize all the installed RAM? Here we explain it to you in a simple but detailed way.
Your operating system is 32-bit
Possibly the main cause that does not show all your RAM memory is that you have a 32-bit operating system installed. Keep in mind that 32-bit operating systems are limited to a maximum of 4 GB of RAM .
Currently 4GB for desktop desktops is the minimum standard for essential tasks. In other words, it is very common to see computers with 8 GB or even more RAM, a 32-bit operating system will not be able to use such amounts of memory. Given this, the solution is to install a 64-bit operating system.
Anyway, if you are a complete newbie, there are ways to know if your operating system is 32 or 64 bit . Clearly, it is very important to take this into account, because if you have a 32-bit operating system, you will not be able to take advantage of more than 4 GB of RAM.
Some apps / devices use memory
On many occasions Windows shows that there is a certain amount of RAM that cannot be used. This has a logical explanation in most cases and is often due to other devices using RAM.
Undoubtedly the clearest example of this are those systems in which a dedicated graphics card is not installed. In these systems, the most common is that RAM memory is used as video memory .
In such cases, a portion of the RAM memory will not be available, as it is dedicated to the video functions of the computer. Therefore, if you have a computer without a dedicated graphics card, this is very possibly the reason that all the RAM memory is not shown as usable. Clearly the solution to this is to buy a dedicated graphics card.
Configure boot options
Although rare, there is a possibility that your computer is misconfigured and this is the reason why it cannot use all the RAM . On many occasions it is due to the boot system presenting wrong options and settings. Fortunately this can be easily checked and fixed.
- To solve this problem, simply open the ” Run ” tool . You can access this tool by pressing the Windows + R key combination .
- Once the “Run” program appears on the screen, you must write the following in the ” msconfig ” text field. After that, click on the “OK” button.
- A new window will open with the Windows startup setup program. Here you must click on the ” Start ” tab .
- Locate ” Advanced options ” and press there.
- On the right side you will see the option ” Maximum amount of memory “. This option must be disabled, in order for the system to use all of the computer’s RAM memory.
- Make the relevant settings, and click ” OK ” in both windows.
The module is not connected correctly or is faulty
Another reason why all the RAM does not appear is that one of the modules is not working well. We can do several checks, but the simplest is the following.
Assuming you have eight RAM, in two modules, if you verify that the computer shows only 4GB, it is most likely that one of the modules is not working . You can do this check by starting the BIOS of your computer where it will show if the RAM memory is working.
Either way, it may also be that the RAM is failing. Fortunately, there are ways to know if a RAM is failing . In any case, it does not hurt to carry out this check.
Finally, if you find that the RAM memory is defective, you may very well have to install a RAM memory in your PC . However, keep in mind that this is highly unlikely, so do not be alarmed and check all the information displayed before.
