In this article, we will present several ways to enable AHCI mode for SATA in the BIOS without reinstalling Windows 10 & thus improve sầu the performance, efficiency và power consumption of modern HDD and SSD drives…



The stable & fast operation of any computer depends on many factors that affect the performance of individual components. One such factor is the operation mode of the SATA interface, which is responsible for the entire process of transferring data from the hard drives.

Modern technologies are not standing still, but are continually evolving, which leads khổng lồ some conflicts that may occur inside the computer.

For example, an SSD connected via a SATA interface running in the IDE mode, an outdated SATA interface mode that is unable lớn unloông chồng the potential of today’s higher-tốc độ drives. This conflict is possible since today’s motherboard manufacturers leave sầu their users the opportunity lớn work correctly with old truyền thông media without AHCI tư vấn.

It should be noted that most modern motherboards already have the mặc định AHCI mode, but such a problem can happen when installing a more modern SSD on an older board or when purchasing a motherboard, which was in use, where the IDE mode was mix.

How vày AHCI and IDE differ?

IDE is an old SATA interface mode, which is almost the same as its predecessor PATA (PATA used a wide & thin cable). This mode of operation was popular before the widespread introduction of AHCI, which allowed modern drives lớn realize the full potential of speed and features.

AHCI – is a new mode of operation through the SATA interface. Operating in this mode allows you khổng lồ get the maximum efficiency from SSD-drives with a very high tốc độ of data recording. Also, the AHCI mode has more economic power consumption, as well as allows you to replace hard drives without shutting down the computer. Working in AHCI mode fully reveals the capabilities of the SATA interface


Why it’s better lớn enable AHCI?

Enabling the AHCI mode in conjunction with a fast hard disk drive can provide a good boost in computer speed, as its writing speed can increase by 10-20%. By enabling AHCI, users will save time each time when they write files.

How vì chưng I define the current operating mode?

To determine the current operating mode, follow the next steps:

Step 1: Enter the “Control Panel” by right-clicking on the “Start” button.

Step 2: In the window that opens, select the “Small Icons” display mode and click on the “Device Manager” inhỏ.

Step 3: In the window that will open, cliông xã on “IDE/SATA Controllers…“, select your hard disk drive, right-cliông chồng on it & select “Properties

The window that opens will display the operating mode

You can also check the operating mode via BIOS or UEFI. The parameters where the operating mode information is located are usually available in “SATA Mode“, “Storage options” etc. depending on the motherboard Mã Sản Phẩm and firmware

Important: Do not switch modes in BIOS or UEFI, as this will cause the operating system to fail to lớn boot.

How vì chưng I enable AHCI mode for SATA in my BIOS without reinstalling Windows 10?

There are several ways to lớn safely switch between the operating modes while maintaining the correct working system functionality.

Method #1: Enable AHCI mode through the registry

Step 1: First, you need khổng lồ open the registry editor. You can bởi it by right-clicking on the “Start” button và then selecting “Run“. In the text field, you should enter the command regedit và confirm it with the button “OK“.

Step 2: In the opened window, go khổng lồ HKEY_LOCALMACHINE SYSTEM CurrentControlSet Services iaStorV

Step 4: Go lớn HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services iaStorV StartOverride & bởi vì the same steps for parameter 0.

Step 5: Go lớn HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services storahci, press twice on Start parameter & mix value to 0

Step 6: Go khổng lồ HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services storahci StartOverride & set the value lớn 0 for the parameter named 0.

Step 7: Reboot the PC and enter the BIOS, where you need to phối the AHCI operation mode. In different models of motherboards, the path lớn the mode switching screen may have sầu different names. The screenshot below shows the most common option.

Save changes & reboot your computer in safe mode.

After rebooting, a new SATA driver pachồng will be installed, và the system will need another reboot, after which the AHCI mode will enable.

It should be noted that in some cases, this method does not work, which leads to a “Screen of death” and further reboot.

To demo another way, you must return the IDE mode in BIOS.

Method #2: Enabling AHCI mode using Commvà Prompt

Step 1: Turn on your computer, right-clichồng on the “Start” button và open the “Comm& Prompt” or “Comm& Prompt (Admin)

Step 2: In the window that opens, enter bcdedit /set current safeboot minimal & confirm by pressing “Enter“.

Step 3: After completing the operation, you need to lớn reboot the PC, go to the BIOS, và change the operating mode as described in the first method. The computer will boot in safe mode & install the necessary drivers. After that, open Command Prompt (Admin) & enter the commvà bcdedit /deletevalue current safeboot. Confirm by pressing “Enter

After the next reboot, a new operating mode optimized for high-tốc độ SSDs will be enabled.
