So I just installed my new i9-10900 CPU, and new MOBO (Maximus XII Hero Z490 WiFi 6 LGA1200) but for some reason everytime I restart my pc, it is starting in temp throttled mode, but the temp is only around 39 degrees, is this something I could have done while installing? I can use ThrottleStop and it clears it, I am just wanting to know if this is something that could potentially be wrong with the processor.

Thanks guys

Intel XTU does not report BD PROCHOT throttling correctly. It reports this as thermal throttling even though the CPU temperature is not hot at all. It uses the same throttling mechanism within the CPU that thermal throttling uses but the two are not the same.

When a sensor goes bad on the motherboard, it can send a throttling signal directly to the CPU along the BD PROCHOT signal path. BD stands for bi-directional. This allows other sensors to send a signal which tricks the CPU into thinking that it is too hot. The CPU responds by using the lowest multiplier and lowest speed.

When you clear the BD PROCHOT box in ThrottleStop, this prevents external throttling signals from getting to your CPU. Your CPU will still throttle if it ever...
How are you using ThrottleStop to clear this. Are you clearing the BD PROCHOT box? Your motherboard might have a problem with one of the on board sensors. If you need to clear the BD PROCHOT box to get your CPU up to its rated speed then there is a problem with your motherboard.

Open Limit Reasons and see if it shows BD PROCHOT glowing red.

A sensor has gone bad. Your CPU is fine.

If you return your motherboard, the hard part is trying to convince someone of what the problem is. BD PROCHOT throttling is poorly understood, even by Intel. Their own XTU tool is a fail.

So what you are saying is somehow my MOBO is bad? That sucks since I just bought it as well, but oh well I guess it isnt that big of a deal to start ThrottleStop when I start my PC, just kind of annoying. Thanks for the info!
 
Yes, a sensor on your motherboard has gone bad and it is constantly sending a false throttling signal to your CPU. Disabling BD PROCHOT blocks external messages from getting to your CPU.

Use the Task Scheduler to add ThrottleStop to your Windows startup sequence.

You can disable the system tray icons if you do not want to look at it so ThrottleStop quietly runs in the background. If you use the Stop Data feature, you will never know it is there.
