More low-volt action, and some interesting vCore-scaling observations

4.2GHz(42x100) 1.17v 30-min Prime small FFT


Some interesting observation on vCore-scaling:
4.0GHz = 1.144v
4.2GHz = 1.176v
This means it needs 0.032v (1.176v - 1.144v) to scale for these 200Mhz, or 0.016v for each 100MHz.
Then, 4.5Ghz should need 1.176 + 0.048 (3 x 0.016), also it should be:
4.5Ghz = 1.224v
For 3 days ago, I testes with 1-hour prime and got
4.5GHz = 1.272v
This means, it is not scaling propositionally from 4.2GHz to 4.5GHz

There is a big gap between calculated propositional scaling (1.224v) and the actual (1.272v) vCore for 4.5Ghz. We have to cont on some error-margins too, but this gap is too big for that.

Either my CPU is turned to a Persian carpet (LoL, they get better when you use them) in last 3 days, or there is a vCore bump/jump between 4.2GHz and 4.5GHz.
I will try to test 4.4GHz tomorrow hopefully, and then 4.5GHz again, and it should answer most of it.
