Unfortunately my board didn’t pass the 1.6 GHz without voltage bump requirement. I would like to know what’s the proper way of bumping the socs voltage is there a official patch one can apply?

Can ESWIN/Sifive comment on this? Many of us would like to test out higher frequencies above 1.4Ghz, given the Milk-V Megrez advertises it can run at 1.8Ghz. I know you have a develop branch GitHub - sifive/riscv-linux at dev/clk-1.8 that seems to be able to unlock the p550 to run at 1.8Ghz, but is it safe to do so? Any concern about silicon degradation?
Leaving this here but basically use this branch
And follow the instructions posted here
With one very important change(USB WON’T WORK WITHOUT)
Make sure
CONFIG_GPIO_DWAPB
Is set to y it should look like this
CONFIG_GPIO_DWAPB=y
That will be introduce in next release. As of now max freq 1.4 only in production.
