Is it on AUTO? If it is, its normal to get that high occasionally. Most CPU's I had, and let me throw some examples around, the 2700X and 7950X on AUTO will definitely go up to 1.489v (1.5v rounded up).
If you feel its to much you can offset undervolt like I did or Curve Optimize it. It will improve average/peak temperatures sometimes and possibly increase headroom for it to boost longer. Hey, its free performance.
65ish during gaming is actually quite good, so don't worry about that.
I have a video for the undervolting that can help you out if you wish.
Good Luck with the system
