How to Check SLAT Feature of CPU to Use Hyper-V

In this article, after explaining what the SLAT in the CPU is, we’ll check to see if a processor supports it.

How to Check SLAT Feature of CPU to Use Hyper-V

How to Check if Your Processor Supports SLAT

The SLAT is a required system requirement for Hyper-V, which comes as a feature with the Windows 8 operating system.

To enable Hyper-V on Windows 8, your system must have a minimum of 4 GB of RAM and the operating system must be 64-bit. However, your computer’s processor must have the SLAT (Second Level Address Translation) feature.

What is SLAT in Processor?

It is a virtualization feature developed for Intel and AMD processors. This feature was developed to provide more efficient memory management for virtual machines running on Hyper-V. The Second Level Address Translation feature is named using different names for Intel and AMD processors.

  • Intel processors were called EPT (Extended Page Table).
  • AMD processors were called RVI (Rapid Virtualization Indexing).

Nowadays the new generation Intel Core i3, Core i5, Core i7, and Core i9 processors support it.

For example, if the CPU of your old computer is a Core 2 Duo, the processor may not be the Second Level Address Translation feature. Therefore, you need to learn the SLAT component of an old processor.

There are two useful tools to help you when you need to learn the Second Level Address Translation feature of a processor. These tools are;

  • CoreInfo
  • Intel Processor Identification Utility

You can also learn the CPU Second Level Address Translation feature by examining at the processor features from the Intel website.

How to Use CoreInfo

To find out if S-L-A-T support is available, download the CoreInfo program from here.

After downloading the Coreinfo program to your computer, run the CMD command prompt as administrator, as shown in the following image.

Command Prompt (Admin)

After you open the command prompt, type Drive: Type and press Enter to go to the CoreInfo location.

To get S-L-A-T capability using Coreinfo, run the following command at the command prompt.

coreinfo.exe –v

coreinfo.exe –v

You can tell if your processor has SLAT support from the output (*) in the image below.

How to Use Intel Processor Identification Utility

Let’s talk about what the Intel Processor Identification Utility is.

The Intel Processor Utility is a free program that allows you to view features from Intel-based processors developed by Microsoft.

With Processor Utility, you can learn your processor’s speed, frequency, Cache information, number of cores, CPU technologies, virtualization support, and much more.

After reviewing how to use CoreInfo, let’s use the Intel Processor Identification Utility to check if the processor has S-L-A-T support.

First of all, click here to download Intel Processor Identification Utility. After downloading the program to your computer, perform the installation.

The first boot image of Intel Processor Identification Utility is as follows;

To learn about the S-L-A-T capability of your processor, click the CPU Technologies tab in the Intel Processor Identification Utility.

You can check from the image below that Intel VT-x with Extended Page Tables feature is Yes.
