I'm facing the same problem. My batch is L420B887.
To run the tests I had to reduce vcore to 1.125 and deactivate the Turbo Boost (with stock cooler).
For those who are getting 100C temps I suggest you try to reduce the vcore a bit and disable the turbo boost.
I'm searching another cooler to buy to check if I can reactivate the turbo boost.
ken-Intel you should be embarassed for that post. This discussion started 2 months ago, we have a lot of posts detailing the problems, and you say what everyone already knows?!
We want solutions! It's a K processor! We want to reach at least the turbo speed with stock conditions and without being throttled! That is what we bought!
