GIGABYTE Motherboard AMD PBO how to open, AM5 BIOS setup instruction + performance test

This article will teach you how to turn on AMD PBO (Precision Boost Overdrive) on GIGABYTE AMD AM5 motherboards, so you can get more processor performance for free and easily.

GIGABYTE Motherboard AMD PBO Boot Tutorial (BIOS Setup Steps)

First, when you see the GIGABYTE logo during the boot process, press Del on the keyboard to enter the BIOS.

After entering BIOS, click ADVANCED MODE in the upper right corner to enter Advanced Mode, and find Advanced CPU Setting in the Tweaker page. Usually the Advanced CPU Setting option will be marked with a small dot in front of the Advanced CPU Setting option, which is marked with a blue square in the case of the author's motherboard.

△ Enter BIOS and find Advanced CPU Setting.

 

Find Precision Boost Overdrive in Advanced CPU Setting, Precision Boost Overdrive is also marked with a small dot, Precision Boost Overdrive is abbreviated as PBO.

Enter and set PBO to Enabled, then press F10 to save and exit.

△ Find the Precision Boost Overdrive option and tap it.

△ The default is AUTO, manually select AMD PBO (Precision Boost Overdrive) to Enabled.

△ Store and leave.

by Maxon Cinebench An industry-standard benchmarking software, Cinebench 2026 tests GPU and CPU performance using Maxon's powerful Redshift rendering engine.

The new version of Cinebench 2026 adds a test for evaluating the performance of SMT-enabled CPU cores, which means that it is now possible to test: GPU, processor full-core, processor single-core, and processor single-thread performance.

Based on the latest Cinema 4D 2026 and Redshift code, and using the updated Clang V19 compiler, the benchmarking accuracy of contemporary and next-generation processors has been improved to test whether the equipment is stable under high loads, whether the thermal solutions of the desktop or laptop are sufficient to cope with the demands of long-term operation in order to maximize the potential of the CPU, and whether the machine is capable of handling demanding 3D tasks. and whether the machine is capable of handling demanding 3D tasks.

By default the AMD PBO (Precision Boost Overdrive) option will be AUTO, scoring 9973 pts in Cinebench 2026 for processor full-core/threaded CPUs (Multiple Threads), and 752 pts in CPU (Single Core) processor single-core events. The CPU (Single Core) processor scored 752 pts in the CPU (Single Core) processor single-core program.

After following the steps above and setting PBO to Enabled, it scored 10274 pts in Cinebench 2026 for processor full core/threaded CPUs (Multiple Threads), and 763 pts for CPU (Single Core) processor single core items.

After a simple setup, multi-core performance is improved by 3%; single-core performance is improved by 1.4%.
