What is SVM Mode in BIOS? (The Basic Guide)
If you see SVM mode in your computer's BIOS settings, it stands for Secure Virtual Machine mode. If you run virtual machines (VMs) on your computer, enabling SVM mode would essentially give that VM more direct access to your PC's hardware. This ultimately means it offers your virtual machine better performance.
I find it helpful to dig around through settings on any of your devices because this can reveal helpful features that you wouldn't have found otherwise. This was how I learned about SVM mode, and as someone who uses virtual machines very frequently, I turned it on and learned absolutely everything I could about it.
So, if you're wondering what the SVM mode in BIOS is and how you can take advantage of it, you're in the right spot. Let's get straight into what you need to know.
What is SVM Mode in BIOS Used for?
SVM mode in your motherboard's BIOS stands for Secure Virtual Machine mode.
SVM mode is found only on motherboards that use AMD CPUs and is AMD's take on virtualization technology. It may also be called AMD-V in some cases.
What SVM mode and other forms of virtualization technology do on your computer is quite interesting. If you're someone who messes around with virtual machines, then it is the kind of feature that was made for you.
A virtual machine has to tap into the host machine's hardware resources by pulling them from the operating system that it is hosted on. This means it only has indirect access to the computer's hardware.
When a virtual machine isn't able to access hardware directly, there will be a pretty significant performance penalty.
However, when you turn SVM mode in BIOS on, it gives that virtual machine direct access to the computer's hardware. Your virtual machine will no longer need to go through the host operating system to access the RAM, CPU, GPU, and so on.
This means that your virtual machine will have a much higher performance ceiling than before. So, if you use virtual machines frequently, this can be a game changer.
Where Do I Find SVM Mode in the BIOS?
If this sounds exciting to you, you'll probably want to enable SVM mode right away. But where exactly do you find SVM mode in BIOS, and how do you get there?
Open the BIOS
Before you can enable SVM mode, the first thing that you'll need to do is open the BIOS.
This step sounds basic enough, but what makes it tricky is that there is still no universal button used to launch the BIOS when a computer is booting up. It all depends on the specific motherboard manufacturer.
You can check to see if there's a little bit of text that states which button to use, on the screen where the manufacturer logo appears.
If not, try to use the "Del" key or "F2", as these are the likely choices.
Find the Advanced CPU Configuration Settings
Well, once you've entered the bios of an AMD motherboard, the layout varies, once again, depending on the manufacturer.
The good thing is that the layout is roughly similar. The first menu you want to look out for is the "Advanced" one. On some Asus motherboards, you might need to press F7 to enter "Advanced Mode".
Once you're in the Advanced settings, look out for "CPU Configuration" or "CPU Settings".
And just like that, if your computer supports it, you should find SVM mode in BIOS waiting to be toggled in this menu. Keep in mind that you might see it listed as AMD-V, but they are the same thing.
Enable SVM mode here, and that's it. Save your BIOS settings, usually using F10 or F12, and you're good to go.
Is There a Secure Virtual Machine Mode Equivalent for Intel PCs?
SVM Mode sounds like a whole lot of fun if you use virtual machines very frequently, but from the sounds of things, this is only available on AMD boards.
Is there any Intel virtualization technology that you can use instead of needing an AMD board?
Well, there certainly is! Intel calls its hardware virtualization tech "Intel VT-x", or simply just "Intel Virtualization".
The good thing is that Intel Virtualization works pretty much the same as AMD Secure Virtual Machine, giving the same performance boost to virtualization software.
Once you're in the Advanced settings of your BIOS, you'll likely see the option to enable virtualization somewhere.
Why Does My Computer Not Have SVM Mode?
If you don't see SVM mode in the BIOS of your motherboard, the likeliest reason is that it is not an AMD board. This means that you will likely find this hardware virtualization tech under a different name entirely.
However, it is important to under that virtualization technology like SVM mode is not a software feature. It needs to be explicitly supported by your PC hardware, particularly the motherboard and the processor.
Although most modern motherboards support virtualization, if you don't see SVM mode or Intel VT-x anywhere in your BIOS settings, you might just have a mobo that doesn't have that capability.
You can always Google your mobo's model number and check the spec sheet to be certain.
What Exactly is a Virtual Machine (VM)?
Virtual machines might seem like a bit of a daunting topic, but they are quite easy to understand.
A VM is essentially just a completely software-based representation of a computer. It doesn't have any hardware parts, but it is capable of running operating systems and software, storing data, networking, and so on.
Because virtual machine applications are simply programs on your main operating system, they have to be fed their hardware needs through that OS, unlike a "real" OS which would communicate and feed off hardware resources directly.
Virtualization software like AMD SVM mode and Intel Virtualization is cool because it recognizes when you're running virtual machines and provides a "secure virtual machine" environment for them to run on.
It is exactly because of this that they can get direct access to your hardware for significantly better performance.
What Are the Perks of Using a Virtual Machine?
So, it makes sense that you can use a virtual machine to run multiple operating systems on a single computer, but what is the actual use of a "virtual computer"?
Well, the average person might never need to use one of these.
However, with certain professions or interests, the appeal of virtual machines and SVM mode becomes very clear.
First off, for someone like me, I tend to have many virtual machines on a single Windows OS installation because it lets me mess around with different operating systems on a single laptop.
I can have different Linux distros and even macOS, without needing to carry more than one PC!
However, for software developers, virtual machines can serve as a way to test software and experiment in a sandbox that won't touch your actual OS if things go wrong.
It can also save costs for companies since they won't need to get multiple systems for workers. A VM can host various operating systems, which can keep costs low and improve efficiency.
An Android app developer can access an Android VM through the Android Studio software. This will allow them to test apps that they are building straight from their computers, instead of needing to pull out an Android device and mess around with that.
To be honest, there are a lot of good reasons to run virtual machines and have a little bit of fun with them, but it is understandable if you don't have many applications for VMs.
Final Words
SVM mode, or AMD-V, provides a "Secure Virtual Machine" environment for any VMs that you run in your Windows OS. Enabling virtualization gives the VM straight access to your computer's hardware, which will guarantee much better performance.
While SVM mode is only available on AMD motherboards, there is an Intel equivalent that goes by Intel VT-x or Intel Virtualization. Enabling virtualization is dependent on whether your mobo supports it or not though, so always be sure to check that out.

AMD SVM Support — что это в биосе — включать или нет? (Support Vector Machine, SVM Mode)
Приветствую дорогие! Выходят новые материнские платы, процессоры, память.. все железо становится лучше и быстрее. Появляются новые функции. Старые остаются. Но сегодня мы поговорим про одну из старых функций, которая уже давно существует.. не знаю когда появилась у AMD, но у Intel она появилась еще в Pentium 4 модель 662/672 — была простая виртуализация VT-x.
Разбираемся
SVM Support (Support Vector Machine) — опция позволяет включить или отключить технологию AMd SVM (Secure Virtual Machine). Данная технология представляет из себя аппаратную виртуализацию AMD, которая необходима для работы некоторых программ.
Данная технология присутствует почти во всех современных процессорах AMD, у Intel есть своя — Intel VT.
Старые процессоры могут не поддерживать виртуализацию.
Другое описание опции — помогает разгрузить процессор во время использования виртуальны машин, скорее всего данное описание не совсем точно. Хотя по сути эффект именно такой же — если использовать виртуальные машины, а опцию не включать — будут реально дикие тормоза.
Принцип работы — простыми словами
На самом деле ничего сложного нет:
- Виртуализация позволяет некоторым программам посылать команды процессору напрямую — так он их обрабатывает быстрее. Применимо только к специальным программам, которые эмулируют среду — например Андроид, Windows, Линукс и другие.
- Есть обычная виртуализация и расширенная. Первая — обеспечивает прямой доступ к процессору. Вторая — доступ к устройствам на шине PCI (например аудио/видеокарта).
- Теоретически, аппаратную виртуализацию могут использовать и некоторые обычные программы, например Хром или видео-плеер. Почему? Вы наверно слышали где-то — аппаратное ускорение. Я об этом. Оно может работать быстрее при включенной виртуализации. Такое ускорение вроде есть в Хроме, и может быть в некоторых видеоплеерах.
Нужно ли включать?
И здесь тоже все очень просто:
- Чтобы ответить на этот вопрос, скажу иначе — отключать нет смысла. Технология никак не грузит ПК, не меняет принцип работы процессора, просто включает в нем некую инструкцию и все.
- При отключенной опции иногда могут быть проблемы при установке некоторых программ — они просто могут сообщать вам что нужна технология виртуализации, иногда они ее называют Hyper-V (хотя это виртуализация на основе гипервизора).
Другое название — SVM Mode:
Какие программы нуждаются в этой технологии?
Программ немного и все они имеют общую направленность — эмуляция среды (операционки):

What Is SVM Mode
What is SVM mode in BIOS? If you are using an AMD motherboard, you will find the SVM AMD option in BIOS. SVM mode meaning also refers to Secure Virtual Machine/ Virtualization mode in AMD BIOS. It provides a secure virtual machine environment but also allows more direct access to the hardware.
AMD defined its virtualization technology for the x86 architecture via the AMD SVM mode. So, in addition to being called SVM, AMD also names the technology AMD-V and lists it in the BIOS under that name.
Tips:
Should I Enable or Disable SVM Mode
Should I enable or disable SVM mode? The answer depends on whether you want to create a virtual machine on the PC. With the BIOS SVM and Hyper-V Windows options enabled, you can install a virtual machine. That is to say, the AMD SVM mode only influences the performance when you are running a virtual machine or emulators like BlueStacks.
If you are not interested in installing a virtual machine, you can disable SVM in the BIOS without affecting anything. Of course, the SVM BIOS option is usually disabled by default, due to security reasons. This is because your PC may lose control if the virtual machine infects with a malicious hypervisor.
How to Disable/Enable SVM Mode in BIOS
Sometimes you may need to enable or disable the SVM AMD in BIOS. If you don’t know how to do that, you can refer to the quick guide below:
Step 1. Start your computer, and then hold the F2 or Delete hotkey before the computer is booted. By doing so, you will enter BIOS.
Tips:
Step 2. Once you enter into the BIOS setup window, navigate to the Advanced tab using the arrow keys and select CPU Configuration.
Step 3. Navigate to the SVM Mode section and select Enabled or Disabled according to your needs.
Step 4. Press Save & Exit to save the changes and restart your system. After that, the SVM AMD mode should be enabled/disabled.
However, some users encounter the BIOS SVM black screen issue when enabling/disabling the option. If you are also troubled by this problem, you can try the several methods below to fix it:
SVM Mode: What It Is and How to Enable It
SVM Mode is a virtualization security layer available within BIOS/UEFI for motherboards with AMD CPUs. Virtualization is a powerful technology for improving the efficiency of your computer and allowing you to run multiple instances of a virtual computer from a single hardware setup. You can run outdated programs or other operating systems using virtualization.
SVM mode won’t affect the performance of your computer to any noticeable degree unless you are trying to run multiple virtual computers simultaneously. Continue reading if you’d like to learn more about SVM and how to enable SVM for multiple motherboard manufacturers.
BIOS
BIOS is a bit of code stored in a chip on your motherboard. The BIOS software is the first software that runs during active startup. BIOS identifies your hardware and helps it interact with your operating system.
While BIOS is the term still widely used today, most modern computers now use UEFI firmware. BIOS stands for basic input/output system, and UEFI stands for unified extensible firmware interface. Many system settings are only available from within the BIOS, including:
- SATA settings
- Boot Order
- Overclocking
- Secure Boot
- SMV Mode
What is SVM Mode?
SVM stands for Secure Virtual Machine. SVM Mode is an option found within the BIOS of AMD motherboards. When enabled, SVM is a virtualization mode that allows you to set up a virtual machine environment on your computer. The SVM security layer can split resources across multiple programs using hardware virtualization. For most AMD motherboards, SVM mode is enabled by default. But some motherboards require you to manually enable AMD’s SVM mode.
What are Virtual Machines?
Virtualization is a technology for running the virtual instance of a computer. You can run multiple operating systems on a single hardware system simultaneously with it. Each VMs runs on its own operating system while running on only a portion of the actual computer hardware. Virtualization is the backbone of cloud computing.
Virtual machines are not as powerful as a standard operating system, and you can expect a 5% drop in CPU and memory performance for VMs. Virtual machines can run operating systems and programs just as a regular computer. They increase the overall efficiency of a computer by allowing computer resources to be distributed among multiple VMs as needed.
You may want to use a VM to run an operating system or program that you can’t normally run on your computer. You can also run older or incompatible software with a virtual machine that’s set to Windows XP or some other outdated operating system. Developers often use VMs to develop an application across multiple platforms to ensure everything works as intended.
Virtual machines are also a safe way to engage in riskier computer activities like surfing the dark web or using torrents.
4 Things You Can Do with Virtualization
1. Backup Your Operating System
You can easily back up your entire operating system, just like you’d create a backup of other kinds of files. This is a great option to protect your entire OS from a cyberattack. Don’t create a copy of a licensed operating system, like Windows, to distribute to friends or family, though.
2. Browse Without Risk
If you want to protect your personal information and computer from cyberattacks, you can use a virtual machine to prevent the corruption of your actual OS. Some cyberattacks, like ransomware, can be devastating. Ransomware usually encrypts your system files and demands a ransom to be paid to have your files decrypted. But if a security attack compromises a VM, it can be shut down immediately without impacting your system.
3. Run Linux or macOS
If you are running Windows operating system but want to use macOS or Linux operating systems, you can do that with a virtual machine. Mac and Linux users have been doing this very thing for years to use Windows-only programs. Ubuntu is a popular Linux distro where Windows users started experimenting with VMs.
4. Test Your Software
If you are developing a software application, you can use virtual machines to test and check that the application is working correctly on other operating systems before deploying.
Does Intel have SVM Mode?
Intel does not use the term SVM Mode. Instead, Intel’s comparable feature is called Intel VT or Intel Virtualization. Intel’s virtualization technology offers the same features as AMDs SVM mode.
How does SVM Mode Impact Performance?
Virtualization only affects performance when a virtual machine is running. This means that enabling SVM won’t affect your computer’s everyday performance. Virtual machines may tax the CPU, but the effects are usually marginal. You shouldn’t experience a drop in framerates when gaming or any interference with other applications. If you enable Hyper-V Windows in conjunction with SVM, you might experience slight performance degradation.
How to Check if Your PC Supports SVM Mode
If you’re uncertain if your computer supports virtualization, follow these steps to find out:
- Use Windows Search to search for System Information and click Open.
- Within the System Information window, scroll down to find Hyper-V Virtualization Enabled in Firmware. If this option says Yes, then your device supports virtualization.
How to Check if Virtualization is Already Enabled
Before hassling with your motherboard’s BIOS and enabling SVM Mode, you can check if virtualization is already enabled using the Task Manager:
- Open Task Manager by searching for Task Manager using Windows Search or pressing Ctrl + Alt + Del and selecting Task Manager from the menu.
- Click on the Performance tab and then select CPU on the left-hand side.
- Underneath the CPU % Utilization graph, find Virtualization and check if it’s Disabled or Enabled. If Enabled, you can start using virtualization.
How to Enable SVM Mode?
If you’d like to enable SVM mode to take advantage of the benefits of virtualization, you will need to access the BIOS. For your motherboard to have SVM mode, you must have a motherboard running an AMD Ryzen CPU.
ASUS Motherboard
- After powering on the computer, press Del or F2 on the first loading screen, you’ll need to react quickly here. But if you miss the small window of opportunity to enter the BIOS, you can shut down your computer and try again.
- Press F7 to enter the Advanced Mode to access advanced features and settings. There’s no need to press F7 for ROG series motherboards because the advanced features are available by default.
- Click the Advanced tab and then select CPU configuration from the options.
- At the bottom of the CPU Configuration page, you’ll find SVM Mode. Click Disabled to expand the drop-down menu and then select Enabled.
MSI Motherboards
- After powering on the computer, press Del on the first loading screen. You only have a short window to enter BIOS from this point, so you’ll need to react quickly. In case you miss it and your computer has already booted, you can shut it down and try again.
- Select OC or Overclocking Settings.
- Scroll down through the options to find and click CPU Features. If you can’t locate CPU Features within your BIOS, select Advanced CPU Configurations instead.
- From the CPU Features page (or Advanced CPU Configurations), locate SVM Mode.
- Click Disabled and select Enabled from the pop-up window.
- Now select the X in the top-right-hand corner and click Yes to the prompt ‘Save configuration and exit?’
- After enabling SVM Mode, restart your PC to ensure these new features are fully applied.
NOTE: If you’re still having issues locating SVM Mode, try clicking on the Search icon in the top-right corner to search for SVM Mode.
Gigabyte Motherboards
- After powering on the computer, press Del on the first loading screen. Just like in other motherboards, your reaction should be on point. Once your computer has booted you won’t be able to access BIOS anymore. In case you missed the window of opportunity, you can shut down your PC and try again.
- On BIOS, select the M.I.T. tab.
- Within the M.I.T page, click Advanced Frequency Settings.
- Now select Advanced CPU Core Settings and find SVM Mode from the list.
- Click Disabled to switch SVM Mode to Enabled.
- Press F10 to Save and exit BIOS, then restart your PC.
ASRock Motherboard
- After powering on the computer, press Del on the first loading screen.
- Within the BIOS interface, find and select the Advanced tab.
- Then click on CPU Configuration and toggle SVM to Enabled.
- Now click Exit and save the changes. Be sure to restart your computer so the settings are fully applied.
SVM Mode In a Nutshell
Virtualization technology made major strides in recent years and is widely used in software development. Most modern computers have virtualization features that can be enabled via the BIOS/UEFI.
Motherboards with AMD Ryzen chips use a virtualization feature called SVM Mode. The feature is specifically available only with AMD CPUs, as Intel CPUs have their own version called Intel VT or Intel Virtualization. SVM Mode allows you to run a virtual computer (or multiple VMs) from a single hardware setup, so you can run different operating systems, browse safely, or use outdated software.
If you’d like to start experimenting with virtual machines, it’s super easy! Just enable the SVM Mode in your AMD-powered PC. Find your motherboard manufacturer above (Asus, MSI, Gigabyte, or ASRock) and follow the steps to enter your BIOS and toggle on SVM mode.
