修复未使用完整 RAM 的 Windows 10： (Fix Windows 10 not using full RAM: )许多用户报告说他们的系统无法利用已安装的可用内存，而是仅在任务管理器(Task Manager)中显示一部分内存，并且只有该内存可供Windows使用。主要问题仍然是内存的另一部分去了哪里？好吧(Well)，在回答这个问题之前，让我们看看实际发生了什么，例如，用户安装了 8 GB 的RAM，但只有 6 GB 可用并显示在任务管理器(Task Manager)中。
RAM（随机存取存储器(Random Access Memory)）是一种计算机存储设备，经常用于存储操作系统正在使用的数据类型，从而提高系统(System)的总体速度。关闭系统后，RAM中的所有数据都会被删除，因为它是一个临时存储设备，用于更快地访问数据。拥有更多的RAM可确保您的系统运行顺畅并具有良好的性能，因为更多的RAM可用于存储更多文件以便更快地访问。但是拥有大量的RAM但是无法使用它对任何人来说都很烦人，这就是这里的情况。您的程序和游戏需要最少的RAM才能运行，但由于可用(RAM)RAM较少（即使您已安装大量内存），您也无法运行这些程序。
为什么 Windows 10 不使用完整的 RAM？(Why Windows 10 not using full RAM?)
在某些情况下， RAM(RAM)的某些部分是系统保留的，有时图形卡(Graphic Card)也会保留一些内存，如果您有集成内存的话。但是，如果您有专用的图形卡(Graphic Card)，那么这应该不是问题。显然，2% 的RAM始终是免费的，例如，如果您安装了 4GB RAM，那么可用内存将在 3.6GB 或 3.8GB 之间，这是完全正常的。对于已安装 8GB RAM但只有 4GB 或 6GB 的用户，可以在任务管理器(Task Manager)或系统(System) 属性(Properties)中使用上述情况。此外，在某些情况下，BIOS可以保留一定数量的RAM使它们无法被Windows使用。
已安装 32 位 Windows 的用户的重要通知(Important Notice for users who have 32-bit Windows Installed)
对于在其系统上安装了 32 位操作系统的用户，无论您实际安装了多少RAM，您都只能访问 3.5 GB RAM 。为了访问完整的RAM，您需要全新安装 64 位版本的Windows，并且没有其他方法可以解决这个问题。现在，在继续为 64 位版本Windows且仍无法访问完整RAM的用户提供解决方案之前，首先检查您安装了哪种类型的操作系统：
1.按 Windows 键 + R 然后输入“ msinfo32 ”并按 Enter 打开系统信息。( System Information.)
2.现在在打开的新窗口中，在右侧窗格中查找系统类型。(System Type)
3.如果您拥有基于 x64 的 PC，则意味着您拥有 64 位操作系统，但如果您拥有基于 x86 的 PC，则意味着您拥有

Fix Windows 10 not using full RAM
Fix Windows 10 not using full RAM: Many users have reported that their system fails to utilize installed available memory instead only a portion of memory is displayed in Task Manager and only that memory is usable by Windows. The main question remains that where are the other part of memory gone? Well, before answering this question let’s see what actually happens, for example, a user have 8 GB installed RAM but only 6 GB is usable and displayed in Task Manager.
RAM (Random Access Memory) is a computer storage devices which is frequently used to store the type of data that is being used by Operating System increase the general speed of a system. Once you shutdown your system all the data in the RAM is erased as it’s a temporary storage device and is used for faster access to data. Having more amount of RAM ensures that your system will run smoothly and will have a good performance as more RAM would be available to store more files for faster access. But having a good amount of RAM but not being able to use it is very annoying for anyone and that’s what the case here. You have programs and games that required a minimum amount of RAM to run but again you won’t be able to run these program as you have less available RAM (even though you have installed a large amount of memory).
Why Windows 10 not using full RAM?
In some cases some portion of RAM is a system reserved, also sometimes some amount of memory is also reserved by Graphic Card is you have an integrated one. But if you have a dedicated Graphic Card then this shouldn’t be a problem. Obviously, 2% of RAM is always free for example if you 4GB RAM installed then usable memory would be between 3.6GB or 3.8GB which is perfectly normal. The above case for users who have installed 8GB RAM but only 4GB or 6GB is available in Task Manager or System Properties. Also, in some cases, BIOS can reserve some amount of RAM making them unusable by Windows.
Important Notice for users who have 32-bit Windows Installed
For users who have 32 bit OS installed on their system, you will only be able to access 3.5 GB RAM no matter how much RAM you have Physically installed. In order to access full RAM, you need to clean install 64-bit version of Windows and there is not other way around this. Now before moving forward with the solutions for users who 64- bit version Windows and still not able to access full RAM, first check which type of operating system you have installed:
1.Press Windows Key + R then type “msinfo32” and hit Enter to open System Information.
2.Now in the new window that opens look for System Type in the right window pane.
3.If you have x64-based PC then it means you have a 64-bit operating system but if you have x86-based PC then
you have a 32-bit OS.
Now we know which type of OS you have let’s see how to fix this issue without wasting any time.
