CHC and Z63A

I am in the middle of trying to undervolt my Z63A with a 1.8ghz proc, and CHC is throwing me a little wrench.

When I choose "Max Battery," it has a multi of 6x and a speed of 800. OK, good to go.

When I choose "Max Performance," which would mean to me the highest possible speed, it gives me a multi of only 12, and a speed of 1.5xxghz.

The only way I can get it to go to 14x multi is to do the "dynamic switching" thing, but I would rather manually change the settings as I need to.

Thanks.

 

I assume you have manually set a voltage for the 14x multipler prior to using "Max Performance" mode?
If you have the Intel Pentium M 730 (1.6 GHz)...then that should be right.
But I suppose you have the P-M 750...

 

Yes, this is correct.

I think the issue is that it won't do true full power (14x multiplier = 1.8ghz) even when I choose "Max Power" as long as I am running off of the battery.

When I chose Max Power while on AC, it did do the 14x multiplier, etc.

 

That is quite odd... perhaps Centrino/Windows will not let you run the 14x multiplier unless you're in Dynamic Switching mode while on battery...acting as some sort of battery saving feature?
"Dynamic Switching" was supposed to be one of Centrino's "power saving" features that extend battery life without hindering (much) performance... so it does make some sense.

I know that for my (older) Dothan/Centrino notebook (M6Ne), I am able to run 15x100 MHz = 1500 MHz (Max Performance) when on battery... but then again, this is a slower AND older chip than yours.

This may give you insight as to how centrino is managed in windows. To get the mhz up to norm you need to run a cpu intesive app. If you open our site and focus on the flash for a few secs you will see the mhz start to rise. Not sure how this relates to this wrench but perhaps you guys can figure it out.
