msgclb: Intel thoroughly documents core VID with a bunch of charts and numbers but they leave out a few details like what MSR contains the VID information and how to interpret it. If your hyperthreading issue has been fixed then I'll have some time to read the Intel docs a little closer. When you have 10 minutes to kill can you try doing a CPU Cool Down Test. Your CPU looks like a good candidate for some information since the temps don't line up.
