Hey! Your new system came together smoothly yesterday, with everything working as expected except for a few quirks. The stock P-cores were running at 5.1GHz, while the XTU kept them at 5.5GHz—just fine, though temperatures were a bit high. You attempted to lower power usage by undervolting and tweaked some BIOS settings. Meanwhile, ASRock’s auto update prompted additional updates. Later, you noticed your P-cores suddenly dropping to 2.5GHz, while the E-cores stayed at 3.9GHz. After some troubleshooting, resetting the BIOS and clearing the CMOS didn’t resolve the problem. The HWMonitor showed the P-cores still at 5.1GHz but only running at 2.5GHz. Someone, could you help me figure out what’s going on? I’m getting a bit frustrated.

If you were tinkering in BIOS, the usual fix is to erase the CMOS, which restores everything to its original state. You lose all your settings, but it’s a necessary step. As for why I didn’t understand it, I’m not sure.
