Precision 7710 massive CPU throttling, DPTF failure.

Hey there,

I've recently got myself a P7710. Fresh Microsoft Windows 10 installed, Dell Command Update installed all Updates. BIOS is on latest version 1.21.3. The machine runs fine under usual load. But a few days ago I tried to play Age of Empires 2 DE and the CPU just crumbled. It went down massively throttling to 0,4 GHz. The game sound crackled. The speed then slowly went up again in small steps of 0.1 GHz, throttled again and again. I thought maybe the device had a bad start. Closed the application and restarted again. This time it went fine without any problems whatsoever. This was a week ago.

Yesterday the Dell did the same throttling again while playing another game again. One session runs fine, another one with massive lag due to this !*$#. I checked the event viewer and I can see a related Microsoft-Windows-Kernel-Processor-Power warning with ID 37. Apart from those warnings occuring for all 8 cores, there is a DPTF failure:

I've checked a WPR recording but I'm unable to get a clue what's going on. The System runs fine otherwise. Tried reinstalling the Intel Thermal driver from Dell. No change in behaviour. Other discussions suggested going into performance mode. It doesn't help at least for my case. Let me know your ideas on solving this.
