My DIY edition running Win10 is getting stuck clocked at .39Ghz. This happens even when plugged in. After a reboot it runs at full speed for a minute or two, then reverts to .39Ghz. [image] I’m following the instructions on this thread and this did not fix it.

Ah, FW13 here, so just a single fan.

This describes the design of the Intel CPUs. I have not seen the problem people are describing. This message is just be describing the design of the Intel CPU. There is a bit of a complex pattern of events before the CPU will throttle like this. Something too hot == H OK temp again == O CPU thro…

Why are we left on our own to figure this out? FW dropped the ball on their design, and I have to deal with a computer that barely functions that I paid thousands for? When is the recall happening?

Contact support for assistance. They are best equipped to help resolve the issue(s). No context was given. Not sure how anyone in the community could advise a course of action.

Support couldn’t solve it. (after literal months of back and forth and jumping through hoops). Support refused a mainboard upgrade. I want an official stance on the fact I was sold e-waste.

Not sure why you would be entitled to a mainboard upgrade instead of a repair or replacement. That in and of itself sounds suspicious (and somewhat demanding) If you want something official it will not be on the forums unless you want official user opinions. Put it up for sale and move on to someth…

I’m still having this issue where the CPU gets completely stuck at 400 MHz. This time, I waited over 24 hours, but without surprise, it didn’t recover on its own. I had to use the disconnect battery trick in the BIOS to get it back to normal. Is there really no proper solution for this? Luckily, I…

I have BIOS 3.17 but still regularly experience the Intel 12th Gen. going into “limp mode” and throttling down until reboot without any apparent cause. :confused:

I’m not sure if we’re experiencing exactly the same issue or if it’s something different. In my case, when CPU gets too hot, it gets downclocked to 400MHz. This is a hardware level throttle, not controlled by the OS. Once the temperature goes down, after some time, it usually recovers its normal sp…

I haven’t logged if there is an overtemperature event beforehand, but I too experience sudden and seemingly permanent drops down to 400MHz, which so far only went away when I shutdown, leave the laptop off for half a minute or so without charger, then do a cold start. Some of these steps might be un…
