Your computer’s RAM is the speedy short-term memory it uses for running applications and open files. The more RAM your computer has, the more you can do at once. Here’s how to check how much your system has.

您计算机的RAM是用于运行应用程序和打开文件的快速短期内存。 您的计算机拥有的RAM越多，您一次可以执行的操作就越多。 这是检查系统容量的方法。

We’ll show you how to check how fast your RAM is, too. Like practically all technology—[except maybe batteries][]—RAM is getting better and faster over time. Newer computers will have faster RAM than older computers.

我们还将向您展示如何检查RAM的速度。 就像几乎所有技术[一样(可能不包括电池)，][except maybe batteries] RAM随着时间的推移越来越好。 较新的计算机将具有比旧计算机更快的RAM。

## 什么是RAM？ **(**What Is RAM?**)** ##

RAM stands for “random access memory.” This is the physical working memory that your PC uses. All your open applications, files, and other data are stored here for quick access. RAM is different from your computer’s [SSD][] or hard drive, which are much slower than RAM. When you launch a program or open a file, it’s moved from your system’s storage to its RAM.

RAM代表“随机存取存储器”。 这是您的PC使用的物理工作内存。 您所有打开的应用程序，文件和其他数据都存储在此处，以便快速访问。 RAM与计算机的[SSD][]或硬盘驱动器不同，后者比RAM慢得多。 当您启动程序或打开文件时，该文件已从系统存储移至其RAM。

The more RAM you have, the more you can do at once. If you don’t have enough RAM for your open applications, your system will slow down as Windows (or another operating system) has to move data in and out of the [page file][] on your system drive. You might even see a low memory error if there’s not enough RAM.

您拥有的RAM越多，一次可以做的越多。 如果您没有足够的RAM用于打开的应用程序，则系统会变慢，因为Windows(或其他操作系统)必须将数据移入和移出系统驱动器上的[页面文件][page file] 。 如果没有足够的RAM，您甚至可能会看到内存不足错误。

How much RAM you need depends on what you do. You’ll need more RAM for playing the latest PC games, running [virtual machines][], and editing 4K videos.

您需要多少RAM取决于您的工作。 您需要更多RAM才能玩最新的PC游戏，运行[虚拟机][virtual machines]以及编辑4K视频。

## 如何检查Windows上有多少RAM **(**How to Check How Much RAM You Have on Windows**)** ##

You can check how much RAM you have in a variety of quick ways.

您可以通过多种快速方法检查有多少RAM。

On Windows 10, [use the Task Manager][]. Right-click your taskbar and select “Task Manager” or press Ctrl+Shift+Esc to open it. Click the “Performance” tab and select “Memory” in the left pane. If you don’t see any tabs, click “More Details” first.

在Windows 10上， [使用任务管理器][use the Task Manager] 。 右键单击任务栏，然后选择“任务管理器”或按Ctrl + Shift + Esc将其打开。 单击“性能”选项卡，然后在左窗格中选择“内存”。 如果看不到任何标签，请首先单击“更多详细信息”。

The total amount of RAM you have installed is displayed here. The Task Manager also tells you the standard it’s using, the speed, its form factor, and how many of your system’s physical memory slots you’re using. You can [install more RAM][] if you can open your PC (not possible on some laptops) and have some spare slots.

在此显示您已安装的RAM总量。 任务管理器还会告诉您它正在使用的标准，速度，其外形尺寸以及正在使用的系统物理内存插槽的数量。 如果可以打开PC(某些笔记本电脑无法打开)并有一些备用插槽，则可以[安装更多RAM][install more RAM] 。

The Task Manager doesn’t offer this useful information on Windows 7. Instead, you can see your total amount of RAM on the Control Panel > System and Security > System page. You can also quickly open this by opening your Start menu, right-clicking “Computer,” and selecting “Properties.” Look to the right of “Installed Memory” under System.

任务管理器未在Windows 7上提供此有用信息。相反，您可以在“控制面板”>“系统和安全性”>“系统”页面上查看RAM的总量。 您也可以通过打开“开始”菜单，右键单击“计算机”，然后选择“属性”来快速打开它。 在“系统”下的“已安装内存”右侧查找。

To see more specific information about your [RAM timings][] on either Windows 10 or 7, we recommend CPU-Z. Download and install CPU-Z, launch it, and click the “Memory” tab to see this information.

要在Windows 10或7上查看有关[RAM时序的][RAM timings]更多具体信息，建议使用CPU-Z。 下载并安装CPU-Z，启动它，然后单击“内存”选项卡以查看此信息。

If you build your own PC, your RAM may not run at its advertised timing until you [tweak the timings][].

如果您构建自己的PC，则在您[调整][tweak the timings]时序之前，RAM可能不会在其公布的时序上运行。

This information is generally displayed in your system’s [UEFI firmware or BIOS][], too. This is particularly helpful if you’re using a PC without a working operating system. Just boot it up, use the keyboard shortcut to enter its BIOS or UEFI firmware (it’s different on each PC), and look for information about the system’s memory or RAM.

此信息通常也显示在系统的[UEFI固件或BIOS中][UEFI firmware or BIOS] 。 如果您使用的PC操作系统不正常，这将特别有用。 只需启动它，使用键盘快捷键输入其BIOS或UEFI固件(每台PC上都不同)，然后查找有关系统内存或RAM的信息。
