Update the BIOS of your X670 and B650 ASUS motherboards for better PBO Enhancement on AMD Ryzen 7000

Fellow owners of the AMD Ryzen 7000 series desktop processors armed onto an X670 or B650 motherboard by ASUS will receive a little upgrade in the form of PBO enhancement tuned by the manufacturer itself.

In short, ASUS has found a better temperature tuning graph that allows the Team Red-exclusive feature Precision Boost Overdrive (PBO) to achieve higher clock speed whenever there’s enough thermal headroom to do so or vice versa by setting various intermittent limits to prevent temperature readings from going through the roof.

The brand has uploaded the latest supported BIOS update to their website where users will need to flash them in DIY style and they even included a step-by-step description to make sure even us tech dummies can enjoy it.

Here’s how.

Download the BIOS update containing the PBO enhancement feature from the ASUS support page, then extract the contents of the ZIP archive. Double-click on the BIOS Renamer tool that was extracted along with the firmware file, which will automatically convert this update to the proper format with the CAP file extension. Then copy or move the renamed file with the CAP extension into the root directory of a USB drive.

To begin the update process, shut off the PC, but leave it connected to power. Then plug the USB drive into the port on the rear I/O panel of the motherboard labeled ‘BIOS’. Hold the nearby BIOS Flashback button down for three seconds, or until the Flashback LED has blinked three times. This will indicate that the update has started. The light will then blink slowly for the next several minutes. When this blinking stops, the update process has completed. At this point, remove the flash drive, turn the PC back on, and the update process will automatically take users to the motherboard’s UEFI BIOS interface, where users will have the option to enable the PBO enhancement.

Once users have entered into the UEFI BIOS interface, activate Advanced mode. Then navigate to the Extreme Tweaker tab and select Precision Boost Overdrive.

In the menu that opens, select Enhancement from the Precision Boost Overdrive dropdown. Then select one of the three preset thermal limits. Level 1 will set the maximum target temperature to 90°C, a modest step down from the default 95°C. Levels 2 and 3 lower the maximum CPU temperatures more aggressively, down to 80°C and 70°C, respectively.

Once the desired level has been chosen, users can save this setting and exit the BIOS.
