No, quite the opposite.

Chips working at a certain frequency get more stable as the voltage increases, but also produce more heat, which is why these things need to be balanced.

Undervolting without actually reducing the clock speed would just introduce even more instability, since it would try to reach the same clock speed, but with less voltage to drive it.

So typically you’d either want to slightly increase the voltage (not recommended as that direction is more for advanced users as you’d need to monitor the temperatures and stress test it to make sure the chip doesn’t get damaged) OR by bumping the clock speed down a notch, something like a ~25 Mhz should do for starters and see if that makes a difference.
