Unlike manual overclocking that might require non-ideal frequencies for all cores in order to get better performance, Precision Boost can dynamically overclock single-thread or a few cores higher than when more cores or all cores are active. Due to Precision Boost granularity, both single-core and multi-core performance benefits. Electric Design Current (EDC) - peak current deliverable from VRMs during transientĪfter raising the limits mentioned above, Precision Boost is given more headroom to act more aggressively.Thermal Design Current (TDC) - sustained current deliverable from motherboard design.Package Power Tracking or Platform Power Threshold (PPT) - the power delivery to SoC.PBO is capable of raising the following limits: PBO opportunistically increases the chip power budget by sensing SoC information (such as power, current, voltage, temperature) as well as motherboard subsystem VRM configuration and modifying that info in order to further push the performance. PBO is an extension to AMD's normal Precision Boost that offers an alternative overclocking solution to manual overclocking by automatically bumping the SoC power budget when possible in order to give Precision Boost more headroom to act more aggressively, thereby achieving higher performance. It provides you real-time information of your systems performance, so you can keep a close eye on the effect of your overclocking settings while gaming. As with all other overclocking mechanisms, using this feature voids warranty.
More details on how to use the AMD OverDrive utility are included in the AMD OverDrive utility section of this guide. This utility can be used to fine tune your performance settings in real time with easy-to-use screens designed for novice to expert users. Precision Boost Overdrive ( PBO) is an opportunistic automated overclocking mechanism found in various AMD processors that pushes the system power budget beyond its rated specifications in order to allow Precision Boost to act more aggressively and achieve higher performance. The critically acclaimed AMD OverDrive utility gives users advanced control of system performance.
