Hey Andreas, your MSI Gaming M5 Z170A and i5-6600K seem to be stuck at low performance. It looks like turning off DB PROCHOT in ThrottleStop helps them run better. This might be due to a faulty sensor. You could try checking the sensor connections or replacing it if possible. Otherwise, you may need to consider a new CPU or motherboard. Let me know what you find!
BD PROCHOT throttling has been a frequent issue on MSI desktop boards for many years. These boards originally featured a Slow Mode control meant for overclockers using liquid nitrogen. It let users safely start at 800 MHz and then switch the board to higher speeds for impressive performance shots. It seems appealing until the switches wear out or become dirty, causing shorts. Once this occurs, the CPU remains locked at 800 MHz. I checked the manual for my board but didn’t find any reference to the Slow Mode feature. If you’re not interested, look for a small toggle switch on the motherboard. Using ThrottleStop clears the BD PROCHOT box, telling the CPU to disregard external throttling commands. Most likely, these aren’t standard temperature switches but could be a failed external switch. Even if BD PROCHOT is disabled in ThrottleStop, your CPU can still thermal throttle when overheating. You have two options: keep using ThrottleStop to block the signal or contact MSI to request a replacement board. Trying to reach someone at MSI about this problem should be challenging. When someone asks you to reinstall Windows, it won’t solve the issue.
