Installed RAM (Memory) Usable Issue

Question

Need to know does 64GB of Installed RAM (Memory) is fully usable means Usable RAM should be 64GB or the usable RAM will be less than 64GB?

My PC is being operated by Windows 10Pro 64 Bits.

Hello neerav_d

Welcome to Microsoft Community.

The amount of usable RAM in a system can vary depending on various factors, including the operating system and hardware configurations. In your case, with 64GB of installed RAM on a Windows 10 Pro 64-bit system, the usable RAM should be close to the full 64GB.

However, there are a few factors that can affect the usable RAM:

• One factor is the system's hardware architecture. For example, some older systems may have limitations that prevent the operating system from fully utilizing the entire installed RAM.
• Another factor that can affect usable RAM is the specific version of the operating system. Windows 10 Pro 64-bit supports up to 2TB of RAM, so in theory, you should be able to utilize the full 64GB without any issues.
• It's important to note that the operating system reserves a portion of the RAM for its own use. This includes resources required for the system to function efficiently, such as caching, system processes, and device drivers. The amount of reserved RAM can vary depending on the system's configuration and the applications running at any given time.

Keep in mind that even if the usable RAM is slightly less than the installed RAM, it's usually due to the operating system's allocation for its own processes and is not a cause for concern.

I hope the above explanation can help you understand more. If there is anything unclear, please feel free to reply.
