Just a question for those that may know for a fact.

is it detrimental for the cpu droping and climbing from .007V/800MHZ to 1.100V/2000MHz all the time???

Is there anyway when using AC power to set the cpu to always run at 2000MHz???

quick anwsers: no, yes...

the PM is designed with SpeedStep technology... it steps up and down in speed (Mhz) as needed... the higher the speed the more voltage it needs...

yes you can set RMClock on Maximal (or Minimal) and it will run at whatever speed you set all the time...

this is not advised, Intel designed the chip to adjust its speed to what is required at any given any time...

Hey. Is it possible to undervolt Celeron-M?

Cool, thanks for the info and reply.

I set mine to max performance on AC, and dynamic switching (speedstep) when on battery. Gives better performance on AC that way.

I'm a little confused. I set my max 15x VID to be 1.100, and the min 6.0x to be 0.748. How do you set the options so that it just Speedsteps at these voltages? I can't seem to make it Speedstep like this

Dozzit · 08-15-2005, 12:49 PM

after setting the min and max, set AC Profile to Auto Management...

Dozzit · 08-15-2005, 12:53 PM

the min and max settings are so it will stay static at that FID so you can test it without it changin' frequencies/voltages...

WilliamG · 08-15-2005, 12:56 PM

Doesn't work. It's set as auto management, but for some reason RMClock things my CPU is running at almost 100%, when it's not. So it's keeping my CPU at 2.0Ghz.

you may be runnin' ver 1.5... you have to chk Run HLT command when OS is idle

WilliamG · 08-15-2005, 01:00 PM

I made it work. I downloaded the previous version and chose "detect CPU load by different method." Strange they removed that from the new version!

Dozzit · 08-15-2005, 01:02 PM

it's not needed in the new ver... it does it automatically...

Clearly, at least for me, it doesn't. In the new version my CPU was still being stressed...by nothing! So the CPU never clocked down from 2GHz, for no apparent reason.

Actually, now it's not even working in the old version. They both detect my CPU as being 90%~ load.

WilliamG · 08-15-2005, 01:08 PM

Ahh all is well. The CPU load read is just rubbish. It still clocks down correct, - it just reads the load incorrectly.

Which stress test should I run? Just the top one?

Dozzit · 08-15-2005, 01:15 PM

if you mean Prime95, i like the first one mostly, then the second and maybe the third...
