Why does the out of the box voltage is so high though? And as far as I see it is something set by the motherboard manufacturer. Like it varies to brand to brand and betwee chipsets too (Z/H/B). Chasing that +5-10% performance doesn't seem to worth that much when the power consumption and temps go so high (so more noise from the fans, more CPU fan power consumption too etc)
Same with the P1/P2 limits. By default on my motherboard it was 253w/unlimited. Which is crazy when the Intel defaults are 125w/181w (at least that's publicly available on the data sheet)
I at least wish Intel would show somewhere what are the default voltage numbers. Or the motherboard manufacturer's should be more "law abiding", a simple "Enforce Intel factory defaults" should be more than enough.

AMD has 'curve optimizer' which runs some tests and configures enabled boards/cpus to set a voltage offset per core. But it seems best to do that, and then give it a little more voltage to get a stable system.
- haunter 4y ago>Stock voltages should basically work Yet it's all over the place. An Asus Z790, an MSI H770, or an Asrock B760 motherboard would all have different voltages. So stock is very hard to define. Maybe there is an Intel spec but it's not really available to the public.
