on battery: reduced
on AC: automatic

just wondering what everyone runs their processors at? i used to run mine at reduced on battery and highest on AC, but just within the past few weeks, i asked myself "why do i need my processor running at highest, when i'm not really doing anything that is processor intensive anyway?" so i changed it to automatic on AC. my powerbook runs a LOT cooler.

i only switch to highest if i need to encode mp3s or video. other than, automatic is GREAT for my web surfing, emailing, and IM's.

battery: reduced
AC: auto

Thats on my Thinkpad but I think you'll find that most people just do that aswell; or they would run both as auto.

iMac G5 - highest. It's criminal not to.

iBook G4 - automatic on adaptor and battery unless I want something done quickly and the iMac isn't around in which case I put it on Highest.

Battery: Reduced
AC: depends, Normally Highest, but if the fans are running a little loud, I will turn the settings to my custom option. I have it set to the sleep settings of Highest, but the Processing power to reduced. This will let the computer cool down and slow the fans down.

A/C- Highest
UPS Backup- Reduced

I've noticed when my PM G5 is set on Highest, the fans kick on at minimal speeds, instead of blasting to 100% and then back to 0% when on automatic. *shrug*

Both iMac and iBook at highest :D
All though mad jew has the advantage...his also runs mad, so a bit faster than the rest of us :p

I'm probably just paranoid about extended heat giving my iBook an early death.

Everytime i change mine to highest, it automatically changes itself to reduced again... I have an iMac G5. Do I have to disable any option in the system preferences to be able to do so?

How do you control that?

In the System Preferences, go to Energy Saver and under the Options tab, there should be a drop down menu for Processor Performance. :)

it depends on your mac. if you have a g3 or a desktop g4 (at least all desktop g4's ive used) you wont have it. it's only implemented in the mobile g4s (ie ibook and powerbook) and g5s. i guess it's for power reasons in the 'books and heat reasons in the g5s :eek:

It's only in portables and G5 Macs, so not in minis or eMacs. It was there in Panther on my iBook so if you have a portable but don't have the option then that's really weird.

Always on highest. I do dim my screen when I'm on battery power though. I still get almost 5 hours on my iBook.

Battery- Reduced.
AC- Reduced <- (Why do you ask? Well, I use my PB as a Laptop, and it feels like its going to fry my nuts off if its on anything above reduced.)

I will however, change it to highest when there is available desk space.

My Powerbook is automatic for both AC and battery. PowerMac is always on highest.

For my Powerbook:

Automatic when it's plugged in and Reduced when it's not. I occationally put it on Highest when it's plugged in, but mostly I don't since the fans starts spinning then.

Yep, that's what it is. I have an emac g4 1.25ghz bought it last year..my first experience with macs. it does the job but I wish I wouldve gotten a portable---ibook or better yet pb

Powerbook
AC = Highest
Battery = turned off (doesn't charge anymore :( )

G5
Set to highest when doing work. Especially during nifty photoshop tomfoolery.
Otherwise it is reduced.

"Automatic" is just annoying, fans rev up when the computer thinks something intensive is about to happen. Oddly enough, the fans rev up less while at the highest setting.

Always reduced. Except for playing movies, because it isn't fast enough to decode them in reduced mode. Basically, I hate fan noise-- and these powerbooks get HOT!

Yeah, i do that all the time and it everytime i go back there it changed again to reduced. And it's starting to annoy me...

On the PM: Highest - duh.

On the iBook: Highest, but I do dim the screen.

Still got mine (PM) on Automatic...

Hmm would highest bring better performance for something like games? Automatic scales up the CPU speed dont it? Ill have to try it but im sure i read somewhere that Highest was not 'recommended' and shortend the life of apple products.. :confused:

Mm, that might be a justification for using it temporarily.

It certainly helps shorten the life of an affordable energy supply.

IF you run it at highest you get better results, that's why I do.

On battery, it's auto but on AC, I use highest because I'm either using Photoshop or running folding@home.

iBook battery: lowest
" AC adapter: highest

iMac--> usually highest, but if it's a really hot summer day or it's late at night and I don't want the fans to make a sound, then I'll set it to auto.

iBook,
Battery: reduced, to stop my legs from burning.
Power Adaptor: Highest, because I'm using my monitor and am usually doing lots of intensive stuff.
