Signal instability detected in processor timing.
You’re seeing the CPU’s clock speed vary between 1.1GHz and 4.4GHz in Task Manager—this is normal. The i7-9700K and MSI Pro Carbon Z390 are compatible, but ensure your BIOS settings match your motherboard model.
This behavior relates to the Idle C state, which can be turned off via BIOS settings. While the CPU idles, it automatically reduces its clock speed to conserve energy. When you launch an application or play a game, it increases its speed to 4.4Ghz or higher.
