 |
|
I've got a laptop with a Celeron M in it. From what I understand it's just a Pentium M without SpeedStep. Does this mean I can't use frequency scaling on it?

| I do not have a Celeron M myself, but as far as i remember, frequency scaling works with the Intel Pentium 4 clock modulation driver included in the kernel (if built as a module, it is called p4_clockmod). |
