Linux may reset CPU clocks to default values when Ryzen CPUs are detected.
Linux may reset CPU clocks to default values when Ryzen CPUs are detected.
In my bios I list a clock speed of 3.4ghz with an undervolt setting at 1.0875v. On Windows everything functions properly and temperatures appear correct. After switching to Linux, the CPU runs at the default 3ghz. I plan to check the bios for any unexpected settings but feel like I might have disabled something important. I also shared a Geekbench test showing my CPU is slower than expected. My single core seems too low compared to its 3.4ghz rating, while multicore performance should be higher given all cores are at 3.4ghz. It might be an issue with OEM settings, though Linux generally doesn’t affect CPU behavior much.
After checking the BIOS and disabling core performance boost, the system actually slows down itself. The same settings worked fine in Windows before; it was stable at 3.4GHz. Any advice would be appreciated. I prefer Linux but having an incorrect clock speed and noisy fan control is quite bothersome.
After many adjustments to the bio, the performance doesn't reach 3.4GHz consistently. I know it makes sense for the CPU to slow down when not in use, but it doesn’t appear to respond to workload changes. In a multicore benchmark, it often stays near that lower frequency and changes unpredictably. Anyone have encountered this problem? Any tips to push the CPU clock higher?
If it's been overclocked, the result will match whatever you set during the overclocking process. Your Linux installation won't influence that. How is your system currently being overclocked? If you used software like Ryzen Master, those adjustments typically don't persist beyond what you changed.
Overclocked settings in the BIOS. Now I realize it’s still running at 3.4ghz but keeps dropping to 2.7ghz during heavy multithreaded tasks, then fluctuating back. That’s why my multicore performance drops significantly compared to Windows. On Windows it stays steady at 3.4ghz all day, whereas on Linux it underclocks and then struggles to maintain the higher frequency. I’m noticing much lower scores in Linux benchmarks despite the stated maximum clock speed. Some Ryzen-specific apps are running, but power consumption and voltage readings don’t match expectations. Do you or anyone else know how to make my Ryzen CPU stay at a consistent high clock? I see both Linux and Windows have clocks that are unstable, but the benchmark results are far from what I expect.
Geekbench link provided points to a CPU with 4.1 GHz according to the system monitor. Windows performance metrics show similar details in the BIOS settings. On my ASUS X470-i Tuner, the specifications are listed as: D.O.C.P Standard DDR4-3200 with clock speeds ranging from 16 to 36 MHz. Performance enhancements include boosted core frequency and overclocking options.
I successfully resolved the issue after updating to a newer kernel and using a driver that was previously installed but not found. It's still experiencing some fluctuations, though the performance appears more consistent now. The clock speed is currently around 3.4GHz.
