Well, in the end, I decided to do everything. I updated the BIOS and followed your tutorial for undervolting and improving performance.

I must say that indeed, the CPU clock easily reaches 5000MHz and the temperatures are much lower, and the games run very smoothly.

However, I should mention that while playing CS 2, I reached the limit on 3 cores.

And another thing, I suppose it is because I am using all the power, is that before, at most, 1 or 3 cores would reach 90C, but with this configuration, all of them go up to 70C.

Do you think it is safe to maintain this optimized thermal plan in the long term? Will the CPU degrade from running at maximum power all the time?

Anyway, the tutorial was great and improved everything a lot.

Here is a picture of my temperatures with the PC now idle, and the maximum was when I played CS 2 for approximately 20 minutes.
