Please tell me,
the frequency of the i 7 2670 processor drops to nominal when working with a gtx 770 m video card.
thermal paste changed, everything is clean.
when the processor is loaded, it works with the turbo boost turned on at 2850, the temperature is stable at the same time, 80-90 gr, and all the rules.
During tests, the video card warmed up to a maximum of 83 degrees, it works perfectly.
but in games, trouble, throttling tormented, the processor frequency drops to 789 hertz after a short work at 2400-2800 hertz.
save help!!!

90 degrees is not normal temperature, throttling is not in vain turned on
