[Undervolting] cpu, chipset and vga
Hi I own a HP 550 15,4" notebook mounting a celeron M 530 which doesn't have speedstep technology for power savings.
I would like undervolt the cpu the chipset and gma if possible. Unfortunately the bios of all notebook I had never offered this option.
I know there's an application ad RMclock which should allow to reduce the voltage on the cpu.
Are there any other similar applications?Is possible reduce the voltage of the chipset and vga?
The vga is an integrated Intel gma x3100.

From what I could see, the Celeron M 530 does not support Speedstep and therefore is always running at full speed and full voltage. I had a Celeron M 360 in my old laptop. As far as I can tell, there's nothing you can do to reduce the power unless the motherboard supports it in the BIOS. (which most laptop's don't) I eventually swapped it for a Pentium M 725. WAY better. It blows my mind that Intel would ever produce a laptop CPU that doesn't support something as basic as this. I guess it's to push people to spend the money on the more expensive CPUs. Maybe some of the newer mobile celeron cpus do have speedstep. I haven't checked. But because of this experience I avoid them like the plague for laptops...
Now if you're talking MoDT, then that's a difference story. My celeron M 360 in an DFI 915Gm microATX motherboard works great and stay very cool. The couple watts you save with speedstep there aren't as noticeable as in a laptop. Plus I do have the option to reduce the voltage on this motherboard.

new CPUs may like better CPUgenie software (as written on the 263rd page of the topic )

for my CPU (P7350), CPUgenie works best!
it recognizes all available voltages, halfed multipliers and SuperLFM.
my states:
0.8GHz - original 0.925V - stable (orthos prime) 0.925V (SuperLFM)
1.6GHz - original 1.000V - stable (orthos prime) 0.925V
2.0GHz - original 1.250V - stable (orthos prime) 0.950V
huge difference in thermal dissipation. guess battery will like it, too.
