NHC - custom ULV Pentium M (banias, on R40)

[kajencik]

I've recently disoveder this great tool (Notebook hardware control) This is a first software which can properly display cpu temperature for my R40, and much more... Really good work out there I've setup my own clock change modes and even the voltage levels, and here comes my question:

I changed the voltage for all CPU clock rates to match the ULV pentium M and it works and is stable! does this meand that when I'll limit maximum CPU frequency to the ULV banias speeds, I have the ULV pentium M? Are there any other changes than the voltage with the LV and ULV CPU's compared to the normal ones?

Mostly. Even at the same voltage, each chip randomly consumes a slightly different amount of energy. Intel would test the chips, and sometimes a chip would not meet power requirements even at the low voltage. This is probably pretty rare, so your chip is most likely effectively a ULV.

The voltage can go below ULV levels, you know, but it takes a bit more testing. You can also lower the voltages of the higher speeds.
