如果您在运行图形密集型应用程序（例如视频编辑或 3D 建模所需的应用程序）时遇到错误，则可能没有足够的VRAM。幸运的是，在花钱升级显卡之前，
您可以采取一些措施来增加 VRAM 。(VRAM)
本教程将告诉您有关在 Windows PC 上增加VRAM所需了解的所有信息。
什么是显存？
视频随机存取存储器(Video Random Access Memory)( VRAM ) 是您的 PC 用于存储图像数据的存储器。它与GPU处理器一起在显示屏上渲染像素。
这就是集成显卡功能不是很强大的原因之一——它们没有自己的专用VRAM。相反，他们必须共享系统 RAM才能工作。另一方面，专用GPU确实有自己的(GPUs)VRAM。
如果您没有足够的VRAM来运行正在运行的程序，则可能会出现许多错误。最直接的方法是购买一张新的高端专用显卡，其VRAM容量比当前显卡更大。对于具有集成显卡的用户来说，这并不总是一个选择，而且它可能非常昂贵。
幸运的是，您可以通过Windows设置来增加(Windows)VRAM。但是，请务必注意，增加VRAM可能无法解决您的问题。同样，您需要注意分配的金额。
(Are)增加专用视频 RAM(Increasing Dedicated Video RAM)是否存在风险(Risks)？
当您增加VRAM时，您会将系统RAM重新分配给VRAM。如果您的系统RAM太低，您将遇到随机冻结和崩溃问题。这意味着当通过系统增加VRAM时，您需要确保有足够的系统内存以使您的 PC 保持正常运行。(VRAM)
如何在Windows 10和 11
中增加专用 VRAM(Increase Dedicated VRAM)
有几种方法可以增加PC 上的专用VRAM 。但是，在继续之前，您应该检查系统上已有的VRAM量和可用图形内存总量。无论您是尝试增加 Windows 10 还是 Windows 11 上的 VRAM(increase VRAM on Windows 10)，过程都是相同的。
- 打开“开始”菜单(Start Menu)并导航至“设置”(Settings)。
- 转到系统。
- 在“显示”(Display)中，滚动到页面底部并选择“高级显示设置”(Advanced Display Settings)。
- 选择(Select Display Adapter Properties)显示器 1(Display 1)的显示适配器属性。
- 在弹出窗口中，查看您有
多少VRAM（专用视频内存(Dedicated Video Memory)）和共享系统内存。(Shared System Memory)
如果您没有大量可用的共享系统内存，则更改内存分配以增加VRAM是不明智的。
如何通过主板 BIOS 设置增加(Motherboard BIOS Settings)VRAM
BIOS是初始化硬件并向Windows操作系统提供运行时服务的固件。(BIOS)在这里，您将找到可让您更改VRAM 的(VRAM)基本设置。
- 要访问BIOS，您需要重新启动计算机。
- 重新启动时，等待Windows徽标出现。然后，重复按 F2、F5、F8 或Del键，直到进入BIOS设置。
注意：如果这对您不起作用，您的主板可能使用不同的键来打开BIOS设置。访问制造商的网站或在线搜索您的BIOS密钥。
- 在BIOS菜单中，找到名为Graphics Settings、Video Settings、DVMT pre-allocation 、Advanced Chipset Features、UMA Frame Buffer Size或VGA Share Memory Size 的(VGA Share Memory Size)选项。具体名称将根据您的主板制造商而有所不同。
- 在下拉菜单中，增加分配的预分配VRAM量，然后保存并退出。确保重新启动计算机以使更改生效。
如何通过注册表编辑器增加(Registry Editor)VRAM(Your VRAM Via)
您还可以使用Windows 注册表编辑器(Windows Registry Editor)增加VRAM。就是这样：
- 在键盘上，按Windows键 + R 打开“运行”(Run)对话框。
- 键入 regedit 并选择“确定”。
- 在左侧菜单中，导航至以下路径：HKEY_LOCAL_MACHINESOFTWAREIntel。
- 右键单击(Right-click)Intel文件夹，然后选择“(Intel)新建密钥”(New Key)。
- 将新文件夹命名为“GMM”。
- 确保(Make)您位于新的GMM文件夹中。然后，右键单击右侧窗格中的可用空间。Select New > Dword（32 位）值(Value)。
- 将其命名为“DedicatedSegmentSize”。
- 双击DedicatedSegmentSize。在“基数”(Base)下，选择“十进制”(Decimal)并在“值(Value)数据”框中键入“512”。单击“确定”(Click OK)。
- 重新启动计算机以使更改生效。
如果您想随时撤消此设置，只需返回注册表编辑器并删除Intel下的GMM文件夹。
升级您的显卡
如果您的Windows PC 仍然无法有效运行，您将需要升级显卡。如果您想要一台能够处理高级图形的计算机，最好选择具有良好图形处理单元的计算机。

在 Windows 中增加 VRAM
现在您知道如何在Windows 11中增加(Windows 11)VRAM。如果软件方法不适合您，具有更多图形功能的电脑将比您想象的更能增强您的体验。
How to Increase Dedicated VRAM in Windows 11
If you’re experiencing errors when you run graphically intensive apps like those required for video еditing or 3D modeling, you maу not haνe enoυgh VRAM. Luckily, there are some things you can do to increase yoυr VRAM before you fork out the cash to upgrade your graphics card.
This tutorial will tell you everything you need to know about increasing VRAM on your Windows PC.
What Is VRAM?
Video Random Access Memory (VRAM) is what your PC uses to store image data. This, along with your GPU processor, renders the pixels on your display monitor.
This is one reason why integrated graphics cards aren’t very powerful — they don’t have their own dedicated VRAM. Instead, they have to share the system RAM to work. Dedicated GPUs, on the other hand, do have their own VRAM.
Many errors can occur if you don’t have enough VRAM for the programs you are running. The most straightforward approach to this is to purchase a new, high-end, dedicated graphics card with a greater amount of VRAM than your current one. This is not always an option for users with integrated graphics, and it can be very expensive.
Fortunately, you can increase your VRAM via Windows settings. However, it’s important to note that increasing your VRAM may not fix your problems. Likewise, you need to be careful with how much you allocate.
Are There Risks to Increasing Dedicated Video RAM?
When you increase your VRAM, you reallocate system RAM to VRAM. If your system RAM is too low, you will encounter random freezing and crashing issues. This means that when increasing VRAM through your system, you need to ensure enough system memory for your PC to remain functional.
How to Increase Dedicated VRAM in Windows 10 and 11
There are a few ways to increase the dedicated VRAM on your PC. However, before proceeding, you should check the amount of VRAM and total available graphics memory you already have on the system. Whether you’re trying to increase VRAM on Windows 10 or Windows 11, the process is the same.
- Open the Start Menu and navigate to Settings.
- Go to System.
- In Display, scroll to the bottom of the page and select Advanced Display Settings.
- Select Display Adapter Properties For Display 1.
- In the pop-up window, look at how much VRAM (Dedicated Video Memory) and Shared System Memory you have.
If you don’t have a lot of shared system memory available, it is unwise to alter the memory allocation to increase your VRAM.
How to Increase Your VRAM From the Motherboard BIOS Settings
The BIOS is the firmware that initializes your hardware and provides runtime services to your Windows operating system. Here, you’ll find the basic settings that let you change VRAM.
- To access the BIOS, you need to restart your computer.
- As it’s restarting, wait for the Windows logo to appear. Then, press the F2, F5, F8, or Del key repeatedly until you enter the BIOS settings.
Note: If this doesn’t work for you, your motherboard may use different keys to open the BIOS settings. Go to the manufacturer’s website or search online for your BIOS keys.
- In the BIOS menu, locate an option named along the lines of Graphics Settings, Video Settings, DVMT pre-allocation, Advanced Chipset Features, UMA Frame Buffer Size, or VGA Share Memory Size. The specific name will alter depending on your motherboard manufacturer.
- In the drop-down menu, increase the amount of pre-allocated VRAM allocated, then save and exit. Make sure you restart your computer to allow the changes to take effect.
How to Increase Your VRAM Via the Registry Editor
You can also increase your VRAM using the Windows Registry Editor. Here’s how:
- On the keyboard, press the Windows key + R to open the Run dialog box.
- Type regedit and select OK.
- In the menu on the left-hand side, navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Intel.
- Right-click the Intel folder, then choose New Key.
- Name the new folder “GMM.”
- Make sure that you are in the new GMM folder. Then, right-click the free space in the right pane. Select New > Dword (32-bit) Value.
- Name it “DedicatedSegmentSize.”
- Double-click DedicatedSegmentSize. Under Base, select Decimal and type “512” in the Value data box. Click OK.
- Restart your computer to allow the changes to take effect.
If you would like to undo this setting at any point, simply go back to the registry editor and delete the GMM folder under Intel.
Upgrade Your Graphics Card
If your Windows PC is still not running efficiently, you will need to upgrade your graphics card. If you want a computer that can handle advanced graphics, it’s best to look at computers with good graphics processing units.
Video cards from gaming PC brands such as NVIDIA and AMD Radeon are built to handle more intense graphics than the integrated Intel HD graphics that tend to come with a standard PC.
Increasing VRAM in Windows
Now you know how to increase VRAM in Windows 11. If the software methods aren’t working for you, a PC with more graphics capabilities will enhance your experience more than you realize.
