well, reviving this thread worked once, so let's pull the stake out of its heart and see if it might draw a ragged breath or two again...
I'm about to 'update' my T60p from win2k to XPsp3...just a plain vanilla XP install, as minimal as possible.
I do almost entirely '2d' CAD/CAE work, and I don't play any games; and rarely use any form of 3D...so I'm not concerned with 3d 'performance'.
I'm a bit obsessed with eliminating (especially from registry and always-running processes) anything that isn't truly -required-.
And because I have to burn $$diesel to make each watt of power we use (we're off-grid), I need to minimize power-consumption in every way possible.
Thus, I wish to install ONLY the ATI driver....NOT the CCC, which I never use, and which seems to always be running something in memory even when 'closed'.
I -do- need the ATI chip to be programmed to its most power-saving mode and clock-rates of course (as power-play allegedly does); but I'm thinking that CCC isn't the only way to do that.
My understanding is that such settings are done 'once', at boot.....and thus should not -require- CCC to run constantly. I am not sure yet what utility I might use at boot-time to set the chip's registers properly tho...??
Note that if the 3D portion of the gpu can be shut off completely (which I've gotten the impression from some reading might be possible), that's likely to be entirely usable for 99% of what I do...and might well save a ton of power and heat.
Sooo...to put all this into 'question' form....
Do the modded desktop-drivers allow for the same or better LOW power operation of the GPU?
And do they provide for UNDERclocking?
Also, do they run OK --without-- CCC installed?
PS: Has anyone run the 'normal' IBM driver -without- CCC installed, and does that work well? If so, what procedure did you use to get only the driver to install?
Any other info, observations, and links, regarding minimizing ATI power and installed-software for a 2d-only no-games situation would be greatly appreciated.
