MSI Boosting Further Speed on 800-Series Boards with PBO BCLK Booster
MSI introduces a big update to all its AM5 motherboards to push AMD Ryzen processors more aggressively without difficult manual tuning. This feature is called PBO BCLK Booster and enables the new 800-series MAX lineup to provide substantial performance gains in applications as well as cooling games.
What is PBO BCLK Booster
It mainly utilizes these hybrid BCLK Base Clock generators found on MSI's MAX series 800-chipset motherboards along with the B850MPOWER and enthusiast MEG X870E GODLIKE. It basically automates the entire BCLK overclocking process, which is cool, he says, because that's how you increase the base frequency of the CPU.
Users can access this tool directly in the BIOS, offering a simple one-click solution to enhance system speed. MSI provides two distinct presets:
- Profile 1 A moderate boost (e.g., adjusting a Ryzen 7 9800X3D base clock to 103 MHz).
- Profile 2 A more aggressive tune (e.g., adjusting the same CPU to 105 MHz).
While the feature keeps CPU voltage on Auto to let the processor manage its own power requirements, MSI notes that BCLK adjustments can introduce instability, so users should test their systems after enabling a profile.
Performance Gains UP to 15% Improvement
With the PBO BCLK Booster combined with the memory High Efficiency Mode from MSI DDR5 memory (specifically DDR5-6000 Tighter profile), the manufacturer claims significant increases in FPS counts with stock settings. Internal testing results are as follows:
- DOOM The Dark Ages Up to 15% improvement.
- Far Cry 6 Up to 7% improvement.
- Cyberpunk 2077 Up to 6% improvement.
- Metro Exodus Up to 5% improvement.
Crucially, this feature can be stacked with MSI's existing X3D Gaming Mode, allowing users to maximize the potential of Ryzen X3D chips.
Availability
Gamers who want to try their luck on these settings should go directly for PBO BCLK Booster in the BETA BIOS release based on AGESA 1.2.0.3G. A complete turning will generally be anticipated by the upcoming AGESA 1.2.7.0 update.
