可是我看網路教學...那邊只是修改標籤
並沒有實際更動電壓.....

說明也是這樣寫的......

"Here you can edit the entries of the voltage table, or even add
new entries if you see there is enough space for them.

A entry consist of a label eg. '1.3V' as identifier for the driver
and
the actual VID eg. '03' which is set to the voltage regulator.
You must note that the voltage label is not responsible for the
output voltage, it is only used by the driver to select correct
VID.
So changing e.g. '1.3V' to '1.9V' will NOT give you
voltage of 1.9V, the voltage set by the entry's VID
will still be 1.3V."
