CPU Stuck at 0,78GHz (HELP!)

Check the Power Management settings, maybe it's configured on Minimal / Power saving something... you can force processors to stay below some threshold ex:

It's possible the PSU is causing issues that triggers the CPU to think he's thermal throttling, or, it's also possible that you didn't peel the plastic under the cooler ?

I mean it did say in bold "Remove this cover before putting on thermal paste" and i did remove it first thing

Yeah, I know, but you would be surprised !

This problem is common and rarely has anything to do with the power supply.  Intel XTU does not report this problem correctly.  It shows thermal throttling even though the CPU temperature is just fine.

 

Try running ThrottleStop instead.  Open up the Limit Reasons window and you will likely see the real reason your CPU is throttling.  BD PROCHOT will be lit up in red.

 

 

BD PROCHOT stands for bi-directional processor hot.  This allows other sensors on the motherboard to send a throttling signal to the CPU.  When one of these sensors goes bad, it will constantly send a throttling signal.  On the main screen of ThrottleStop you can clear the BD PROCHOT box so your CPU will stop listening to these fake throttling signals and then it will be able to run at its full rated speed.

 

If this fixes things, you can either replace the motherboard or just run ThrottleStop.  It is a simple solution for this problem.

Interesting, learning something new today.  Whether or not that's his issue, this is good info.  Thanks.

Real thermal throttling does not lock the processor to the 8 multiplier, especially when the CPU Package temperature is 69°C away from the 100°C thermal throttling temperature.  There is no reason for this CPU to be thermal throttling.

 

Do a Google search for BD PROCHOT and you will discover that this is a very common laptop problem but it does happen on the desktop boards too.  MSI motherboards are the most likely to have this problem.  They use a slow mode switch designed for extreme overclockers.  When this switch fails, and it frequently does, the CPU will be locked down to the 8 multiplier and will be stuck at 800 MHz indefinitely.  That probably sounds familiar to @Tsu

You are a lot more advanced than I am with that kind of stuff.

update mobo bios? reseat cpu? Is the cpu fan spinning?
