Hi everyone, i recently upgraded from a gtx 1060 to a 6750xt. But since then my CPU 5600X constantly boosts to over 4 Ghz even in idle. Which leads to fan noise.

I am on the windows power saving mode and it still behaves like that. I enabled eco mode in bios and UV the CPU but still same behaviour. Only thing that fixed it was to ddui and put in the old GPU. So my guess is that the adrenaline software is kinda responsible for this, but i dont know what it exactly could be. Any ideas? Excuse my bad grammar, english is not my native language.

I set it to 2.8Ghz all core in bios.

Yes the Adrenalin software can apply Tuning control to both CPU and GPU. However on Default profile (appears as Standard on your screenshot) the CPU should not boost at idle, only when there is a thread or process utilizing resources. But you don't have Standard selected, so you must have a Custom profile applied.

Changed it to Standard and its even worse now, the cpu fan ramps up every 10 seconds. And same issue with adrenaline and task manager. It now boost even higher 4.3 Ghz

AMDwhy123, I think the decision is yours. You can select a very quiet PC or one that does the workload as quickly as possible but is noisier. Use the fan curves to not allow the fans speed to increase making noise. Ryzen will limit the clocks and voltages to keep it cool. John.

If the fan is increasing speed and the processor frequency is boosting to 4.3GHz it is because some process is running that is utilizing the CPU and raising the temperature.

You can use the motherboard BIOS or software utility to select for example "Silent" fan profile rather than "Normal" (or Default) however that just allows the CPU to run hotter.

You may want to investigate what process is utilizing CPU resources every 10 seconds.

So, I found the problem. It had something to do with the AMD chipset driver. It was overwriting the Windows power profile. I uninstalled every AMD driver, let Windows grab the driver through Windows Update, and now, when I change the power setting in Windows from performance to power saving, it clocks the CPU down. When I go back to performance mode, the CPU clocks go up. I don't know how or what the CPU driver team messed up, but that was the solution. Also, the Adrenalin software was not keeping my GPU undervolt setting. Uninstalling it and using MSI Afterburner to undervolt also solved that problem. I heard that AMD drivers had improved, but to me, it seems they only improved on the surface.
