BIOSTAR A320M-H from factory comes with turbo-locked BIOS which means any AM4 CPU will be limited to base clock and PPT values only. Upon our special request with the OEM, we have the updated BIOS which unlocks the turbo performance of AM4 CPUs.
Update Method
The method is fairly simple:
- Format a USB flash drive in FAT32 file system
- Download the BIOS compressed file and extract it directly to USB flash drive.
- Plug the USB flash drive into the system with BIOSTAR A320M-H motherboard and press F12 to enter automatic BIOS update utility. Select A32ES317.PTSย file and press ENTER to start flashing the BIOS (agree with all the warnings).
- Once the BIOS update process is complete system will reboot by itself. If it doesn’t remove the USB flash drive and force restart the system.
- Congratulations, now you’re on the unlocked BIOS.
