想知道什么是专用VRAM（视频 RAM(Video RAM)）？Windows 10需要多少VRAM？您可以增加Windows 10(Windows 10)中的专用VRAM吗？如果您正在寻找这些问题的答案，那么您来对地方了，这里有一个完整的指南。
您是否因游戏延迟、视频播放卡顿、使用视频编辑器或任何其他涉及高分辨率图形的任务而感到沮丧？虽然主要原因可能是硬件过时或劣质，但除了RAM、处理器和GPU之外，还有另一个重要因素决定了图形密集型任务的运行流畅度。
视频 RAM(Video RAM)或VRAM是一种特殊类型的RAM，它与计算机中的图形处理单元协同工作以渲染图形，其大小的增加或减少会极大地影响GPU本身的性能。
如何在 Windows 10 中增加专用 VRAM（视频 RAM）(How to Increase Dedicated VRAM (Video RAM) in Windows 10)
在本文中，我们将介绍几种增加系统上专用VRAM数量的方法。
什么是专用 VRAM？您真正需要多少？(What is Dedicated VRAM & How much do you really need? )
(Video RAM)如前所述，视频 RAM或VRAM是特定于您的显卡的一种特殊类型的RAM 。每次运行图形密集型任务时，图形卡都会调用VRAM加载要显示的下一帧/像素/信息。因此，显存存储了(VRAM)GPU所需的所有信息，包括游戏纹理、光照效果、4K 视频的下一帧、抗锯齿等。
您可能想知道为什么GPU需要自己独特的VRAM并且不使用主RAM？由于VRAM是显卡本身的芯片，与主RAM相比， (RAM)GPU可以更快地访问它，因此显示/渲染图形没有任何延迟。访问下一组信息/图形的速度在游戏中尤为重要，因为一秒钟的延迟/滞后会剥夺您的鸡肉晚餐。
GPU和VRAM之间的关系类似于计算机处理器和RAM之间的关系。
至于你需要多少VRAM？这取决于。
这取决于您打算在系统上执行的操作。玩纸牌游戏，偶尔使用一些轻媒体的糖果迷恋传奇？如果是这种情况，那么 256MB 的VRAM应该绰绰有余。但是，如果您打算在高图形设置下玩PUBG(PUBG)或Fortnite等图形密集型游戏，那么您将需要更多的VRAM。
决定需要多少VRAM的另一个因素是显示器的分辨率。如前所述，VRAM存储要显示且当前由GPU显示的图像/像素。更高分辨率会转换为更多像素，因此VRAM需要足够大以容纳这些像素。
根据经验，使用下表确定您可以根据RAM设置多少(RAM)VRAM。
| RAM |
Recommended VRAM |
| 2 GB |
256MB |
| 4 GB |
512MB |
| 8 GB or more |
1024MB or more |
如何检查系统上的专用 VRAM 数量？(How to check the amount of dedicated VRAM on your system?)
在我们增加个人计算机上的专用VRAM数量之前，让我们检查一下它实际上有多少。请按照以下分步指南进行操作：
1.通过以下任一方法打开 Windows 设置(Open Windows Settings)。
- 按 Windows 键 + X 并从高级用户菜单中选择(power user menu)设置(Settings)。
- 只需(Simply)点击搜索栏，输入Settings，然后点击Open。
- 按Windows键 + I 直接打开Settings。
2. 在这里，单击系统(System)（网格中的第一个选项）。
3. 左侧边栏会出现各种子设置的列表。默认情况下，显示设置将打开，但如果由于某种原因未打开，请单击显示(Display )以访问显示设置。
4. 所有与显示相关的设置都将出现在窗口的右侧。向下滚动(Scroll)以找到高级显示设置(Advanced display settings)并单击相同。
5. 在下一个窗口中，单击Display adapter properties for Display 1。
6. 将弹出一个显示各种显卡/适配器相关信息的弹出窗口，如芯片类型(Chip Type)、DAC 类型(DAC Type)、适配器字符串(Adapter String)等。
专用视频内存(Dedicated Video Memory)的数量也将显示在同一窗口中。
正如您在上面的屏幕截图中看到的那样，窗口正在显示计算机中集成显卡的VRAM （英特尔高清显卡(Intel HD Graphics)）。但是，大多数计算机都有专用显卡，只有在被调用时才会启动，并且上面的窗口只显示活动GPU的(GPU)VRAM。
因此，通过执行一些图形密集型任务（例如玩游戏、播放 4K 视频等）来激活您的专用GPU ，然后再次按照上述步骤检查您的专用GPU的(GPU)VRAM。

在 Windows 10 中增加专用 VRAM 的 3 种方法(3 Ways to Increase Dedicated VRAM in Windows 10)
如果您经常遇到性能下降、低帧率、纹理故障并且正在使用集成显卡，那么您可能需要考虑安装具有足够VRAM以满足您的需求的专用显卡。
但是，上述选项仅适用于 PC 用户，不适用于笔记本电脑。笔记本电脑用户可以尝试下面提到的方法来稍微提高他们的专用VRAM。
方法一：通过BIOS增加显存(Method 1: Increase VRAM via BIOS)
通过BIOS菜单更新VRAM的数量是第一个也是推荐的方法，因为它有很大的成功机会。但是，以下方法可能并不适合所有人，因为某些主板制造商不允许用户手动调整VRAM。
1. 重新启动计算机并在下次启动时访问 BIOS 设置(access the BIOS settings)。
进入BIOS的过程取决于每个主板制造商。要查找特定于您的计算机/制造商的方法，只需谷歌“如何在您的computer brand name + computer model BIOS？”
大多数BIOS菜单可以通过在系统启动时反复按 F2、F5、F8 或Del键来访问。
2. 进入BIOS菜单后，查找图形设置(Graphics Settings)、视频设置(Video Settings)或VGA 共享内存大小(VGA Share Memory Size)等内容。
如果您没有看到上述任何选项，请找到Advanced Settings/options并单击打开。在此处查找上述设置。
3. 扫描预分配的VRAM并将其增加到适合您的值。可用选项通常包括 32M、64M、128M、256M 和 512M。
默认情况下，大多数GPU的(GPUs)VRAM设置为 64M 或 128M。因此，将值增加到 256M 或 512M。
4. 保存您刚刚所做的更改并重新启动系统。
系统启动后，请按照前面文章中提到的指南检查该方法是否有效，并且我们能够增加VRAM的数量。
方法 2：使用 Windows 注册表编辑器增加专用 VRAM(Method 2: Increase Dedicated VRAM Using Windows Registry Editor )
适配器(Adapter)属性窗口为集成显卡报告的VRAM数量并不重要，因为集成显卡会根据需求自动调整以使用系统RAM。Adapter属性报告的值只是为了欺骗游戏和其他任务，只要他们检查有多少VRAM可用。
使用 Windows 注册表编辑器，可以诱使游戏认为可用的VRAM(VRAM)比实际的要多得多。要在集成显卡上伪造VRAM增加，请按照以下步骤操作：(VRAM)
1.通过启动运行命令（Windows键 + R）(Windows)打开注册表编辑器(Open registry editor)，键入 regedit 并按 Enter 或单击开始按钮，搜索注册表编辑器(Registry Editor)并单击打开(Open)。
2.通过单击标签旁边的箭头或双击展开HKEY_LOCAL_MACHINE （可以在左侧面板上找到）。(HKEY_LOCAL_MACHINE)
3. 在 HKEY_LOCAL_MACHINE 中，找到Software并展开它。
4. 查找Intel并右键单击该文件夹。选择新建(New )，然后选择键(Key)。
5. 这将创建一个新文件夹。将文件夹命名为GMM。
6.通过单击选择GMM文件夹。(GMM)现在，当GMM文件夹被选中时，将鼠标指针移动到右窗格并右键单击空白/负区域。
选择New后跟DWORD (32-bit) Value。
7. 将您刚刚创建的DWORD重命名为(DWORD)DedicatedSegmentSize。
8. 右键单击 DedicatedSegmentSize并选择Modify（或直接双击DedicatedSegmentSize）以编辑DWORD值。
9. 首先，将 Base 更改为Decimal ，然后在(Decimal )Value data下面的文本框中，键入一个介于 0 到 512 之间的值。
注意：不要超过512的数值数据。(Value)
单击确定(OK)。
10. 重新启动计算机并检查适配器(Adapter) 属性(Properties)以验证VRAM是否已增加。

3 Ways to Increase Dedicated VRAM in Windows 10
Wondering what dedicatеd VRAM (Video RΑM) is? How much VRAM is required in Windows 10? Can you increаse the dedicated VRAM in Windows 10? If you are looking for answers to these questions then you have come to the right place, here’s a completе guide.
Have you been experiencing an increased dosage of frustration due to laggy games, stuttery video playback, while using video editors or during any other task that involves high-resolution graphics? While the primary cause may be outdated or inferior hardware, there’s another important factor apart from RAM, processor, and GPU that governs how smoothly graphics-intensive tasks run.
Video RAM or VRAM is a special type RAM that works in coordination with the graphics processing unit in your computer to render graphics and an increase or decrease in its size can dramatically affect the performance of the GPU itself.
How to Increase Dedicated VRAM (Video RAM) in Windows 10
In this article, we will go over a couple of methods to increase the amount of dedicated VRAM on our systems.
What is Dedicated VRAM & How much do you really need?
Video RAM or VRAM, as mentioned earlier, is a special type of RAM specific to your graphic card. Every time a graphics-intensive task is being run, the graphic card calls upon the VRAM to load the next frames/pixels/information to be displayed. The VRAM, therefore, stores all the information required by the GPU including game textures, lighting effects, next frame of a 4K video, anti-aliasing, etc.
You may be wondering why the GPU requires its own unique VRAM and doesn’t utilize the main RAM? Since VRAM is a chip found on the graphics card itself, the GPU can access it much faster compared to the main RAM and thus display/render graphics without any lag. The speed of access to the next set of information/graphics is particularly important in games as a single second of delay/lag can deprive you of your chicken dinner.
The relation between GPU and VRAM is analogous to the relation between your computer processor and RAM.
As for how much VRAM do you need? It depends.
It depends on what you intend to do on your system. Play games like solitaire, the occasional candy crush saga with some light media? If that’s the case then 256MB of VRAM should be more than enough. However, if you intend to play graphics-intensive games like PUBG or Fortnite on high graphics settings then you will require a lot more VRAM.
Another factor that governs how much VRAM is required is your monitor’s resolution. As mentioned earlier, VRAM stores the images/pixels that are to be displayed and are currently being displayed by the GPU. Higher-resolution converts to a greater number of pixels and thus, the VRAM needs to be sufficiently large to hold these many numbers of pixels.
As a rule of thumb, use the below table to identify how much VRAM you can set based on your RAM.
| RAM |
Recommended VRAM |
| 2 GB |
256MB |
| 4 GB |
512MB |
| 8 GB or more |
1024MB or more |
How to check the amount of dedicated VRAM on your system?
Before we increase the amount of dedicated VRAM on our personal computers, let’s check how much of it is actually there. Follow the below step by step guide to do so:
1. Open Windows Settings by any of the following methods.
- Press Windows key + X and select Settings from the power user menu.
- Simply click on the search bar, type Settings, and click on Open.
- Press Windows key + I to directly open Settings.
2. In here, click on System (the first option in the grid).
3. On the left sidebar, there will be a list of various sub-settings. By default, display settings will be open but if for some reason it isn’t, click on Display to access Display settings.
4. All display-related settings will be present on the right side of the window. Scroll down to find Advanced display settings and click on the same.
5. In the next window, click on Display adapter properties for Display 1.
6. A pop-up displaying various graphics card/adapter related information like Chip Type, DAC Type, Adapter String, etc. will be displayed.
The amount of Dedicated Video Memory will also be displayed in the same window.
As you can see in the above screenshot, the window is displaying the VRAM for the integrated graphics card in the computer (Intel HD Graphics). However, most computers have a dedicated graphics card which only kicks in when it is called upon and the above window only shows the VRAM of the active GPU.
So, activate your dedicated GPU by performing some graphics-intensive tasks like playing a game, playing 4K videos, etc. and then follow the above steps again to check the VRAM of your dedicated GPU.

3 Ways to Increase Dedicated VRAM in Windows 10
If you are experiencing frequent performance drops, low frame rates, texture glitches and are using an integrated graphics card then you might want to consider installing a dedicated graphics card with enough VRAM suitable for your needs.
However, the above option is viable only for PC users and not laptops. Laptop users can instead try the below-mentioned methods to give a slight bump to their dedicated VRAM.
Method 1: Increase VRAM via BIOS
Updating the amount of VRAM through the BIOS menu is the first and the recommended method as it has a good chance of success. However, the following method may not work for everyone as certain motherboard manufacturers do not allow a user to manually adjust VRAM.
1. Restart your computer and access the BIOS settings on the next bootup.
The process of entering BIOS is subjective to each individual motherboard manufacturer. To find the method specific to your computer/manufacture, simply google ‘How to enter BIOS on your computer brand name + computer model ?’
Most BIOS menus can be accessed by repeatedly pressing F2, F5, F8, or Del key while the system is starting.
2. Once you are in the BIOS menu, look for anything along the lines of Graphics Settings, Video Settings, or VGA Share Memory Size.
If you do not see any of the above options, locate Advanced Settings/options and click to open. Look for the above-mentioned settings in here.
3. Scan for Pre-allocated VRAM and increase it to a value that works for you. The available options usually include 32M, 64M, 128M, 256M, and 512M.
By default, the VRAM for most GPUs is set at 64M or 128M. So, increase the value to either 256M or 512M.
4. Save the changes you just made and restart your system.
Once your system has booted back up, follow the guide mentioned in the article earlier to check if the method worked and we were able to increase the amount of VRAM.
Method 2: Increase Dedicated VRAM Using Windows Registry Editor
The amount of VRAM reported for an integrated graphics card by the Adapter properties window doesn’t really matter as the integrated graphics card automatically adjusts to use the system RAM based on the demand. The value reported by Adapter properties is merely to fool games and other tasks whenever they check how much VRAM is available.
Using the windows registry editor, one can trick games into thinking that there is much more VRAM available then there actually is. To fake a VRAM increase on your integrated graphics card, follow the below steps:
1. Open registry editor by either launching the run command (Windows key + R), typing regedit and pressing enter or by clicking on the start button, searching for Registry Editor and clicking on Open.
2. Expand HKEY_LOCAL_MACHINE (can be found on the left-side panel) by clicking on the arrow next to the label or by double-clicking.
3. In HKEY_LOCAL_MACHINE, locate Software and expand the same.
4. Look for Intel and right-click on the folder. Select New and then Key.
5. This will create a new folder. Name the folder GMM.
6. Select the GMM folder by clicking on it. Now, while the GMM folder is selected, move your mouse pointer to the right pane and right-click on the empty/negative area.
Select New followed by DWORD (32-bit) Value.
7. Rename the DWORD you just created to DedicatedSegmentSize.
8. Right-click on DedicatedSegmentSize and select Modify (or just double-click on DedicatedSegmentSize) to edit the DWORD value.
9. First, change the Base to Decimal and inside the text box below Value data, type a value between 0 to 512.
Note: Do not exceed the Value data over 512.
Click on OK.
10. Restart your computer and check Adapter Properties to verify if VRAM has been increased.
Method 3: Increase Dedicated VRAM via System Settings
1. Open File Explorer by pressing Windows key + E on your keyboard or by double-clicking on the explorer icon on your desktop.
2. Right-click on This PC and select Properties.
3. On the left side of the following window, click on Advanced System Settings.
4. Now, click on the Settings button under the Performance label.
5. Switch to the Advanced tab and click on Change.
6. Uncheck the box next to Automatically manage paging file size for all drives, select C drive and enable Custom size by clicking on the radio button next to it.
7. Finally, set the Initial size (MB) to 10000 and Maximum size (MB) to 20000. Click on the Set button to finalize all the changes we made.
