Processor Power Management?

nicnik · Feb 1, 2009, 01:59 AM

Would like to know what's the requirement for this option to show up in vista under Power Options, is showing up dependant on motherboard or processor?

Anyone else use it? I currently have it set at 5% min, 100% max. (rig sig)

All it seems to do is set my cpu multipier to 12 when it's running idle, and puts it back to 20/21 when under load. I see no reason to not have it on. i may be wrong?

I know the UD5 has dynamic energy saver but i dont think it's related to processor power management (ppm). Is PPM a vista function for dual+ cores only? My only other PC using vista is single core and there is no option for PPM.

Just checked and mine is set at 100% min and max as default. I think this is just a useless Vista feature myself but could be wrong *shrugs*

PPS: I have run Vista X64 on a Gigabyte board and currently an ASUS ... how could Vista power options affect BIOS settings like cpu multipliers?

CPU-Z shows my computer as being on a 12 multiplier when idle, and 21 when under load when using 5-100%.

If the setting is present is there any reason why it shouldnt be set at, say, 5-100% ?

When I first installed vistax64 it defaulted to "balanced" power options which had 5-100% as default.

Coz according to coretemp, when in 5% state it's saving over 100 Watts.

Wow I didn't know it affected the system that way you learn something new everyday

I will have to experiment with it a bit more I know there are BIOS settings to do this but wasn't aware the OS did so.

EDIT: Since both my main machines here run 24/7 even while I am at work I am going to try the 5% to 100% setting myself on them this week.
