Developer and tweaker 1usmus recently unveiled his new ClockTuner utility for AMD Ryzen 3000 processors. ClockTuner uses an automated process to overclock and undervolt Zen 2 CPUs, netting effectively free performance, potentially without stability issues or greater power draw. The tool releases next month, not long before the arrival of Intel’s new Rocket Lake S parts.

Developer and tweaker 1usmus just announced his new ClockTuner utility, an automated tool that apparently overclocks and undervolts AMD Ryzen 3000 series processors with minimal user input. 1usmus partnered with Linus Tech Tips to reveal the new utility.  ClockTuner integrates Prime95 and Cinebench R20 for stress testing and functions as a one-click tool, identifying maximum stable clockspeeds and voltages on a per-processor basis. 

Interestingly, ClockTuner takes advantage of inherent peculiarities in AMD’s chiplet-based process design approach to maximize performance. Most shipping AMD processors have CCXs that vary in terms of their performance and stability profile. The “bad” CCXs will reliably hit base clocks but might struggle to reach higher advertised frequencies.

AMD’s top advertised boost bins are typically only achieved by the best CCXs and the best cores in a particular processor. ClockTuner identifies the best CCXs in a Ryzen processor, allowing for fine-grained overclocks that maximize single-threaded and multi-threaded performance, pushing each cluster as far as it’ll go. Per-CCX overclocking is particularly relevant for higher-end parts like the Ryzen 9 3900X, which feature 4 CCXs. 

ClockTuner isn’t available right now, but should launch in a month. Interestingly, this is close to the launch timeframe for Intel’s upcoming Rocket Lake S desktop processors. While Ryzen 3000 is getting a bit long in the tooth, an extra few percent of single and multithreaded performance could help close the gap with Rocket Lake S.
