64 bit Windows 7, 4GB RAM (3.80 usable)

As an IT administrator, it is important to understand the basics of hardware and software, as well as how they interact with each other. In this article, we will discuss why a 64-bit version of Windows 7, with 4GB of RAM, may show only 3.8GB of RAM as being usable.

First, let’s start by understanding the basics of Windows 7 and the hardware it requires. Windows 7 is a 64-bit operating system, meaning it requires a 64-bit processor in order to run. It also requires 4GB of RAM in order to run properly.

When it comes to RAM, there are two types of RAM that are used in computers: dynamic random access memory (DRAM) and static random access memory (SRAM). DRAM is used for general processing and SRAM is used for caching. The amount of RAM that is available for use is determined by the type of RAM and the size of the memory chips on the motherboard.

When it comes to a 64-bit version of Windows 7, with 4GB of RAM installed, it is important to understand that the operating system will only recognize 3.8GB of the RAM as being usable. This is because the operating system needs to reserve some of the RAM for system processes and other functions. This is why it shows only 3.8GB as being usable.

It is also important to note that this is not an issue with the hardware or software, but rather a limitation of the operating system. Therefore, if more RAM is needed for a particular task, it is important to consider upgrading to Windows 10, which supports up to 128GB of RAM.

In conclusion, when using a 64-bit version of Windows 7, with 4GB of RAM installed, it is important to understand that only 3.8GB of RAM is usable. This is not an issue with the hardware or software, but rather a limitation of the operating system. Therefore, if more RAM is needed for a particular task, it is important to consider upgrading to Windows 10, which supports up to 128GB of RAM.
