Anyone Run Any DC Projects On PIII Laptop's Using "Power Saving Technology?"

[ShotgunSteven]

I will be getting an IBM ThinkPad soon, and they say it does not run at top speeds all the time, to conserve power. Basically, if what you are doing does not require 100% of CPU power, it runs at a lower speed. How does running a project like SETI@Home affect it?

Hey Shotgun I have procured a Laptop for a few weeks and of course it is running Seti. I turned off all the power saving options so it cranks out 2 units a day or so. Its an A22M it does ok.

I believe that the power savingn functions kicked in based on the power source (battery vs. ac jack) and not based on cpu usage but I've never owned a laptop.

I think this page should pretty much answer your question:

Mobile Pentium® III Processors - Intel® SpeedStep? Technology

Basically, when you switch over to battery power, the frequency of the processor is reduced to roughly 60-80% of max. They have a chart on that page showing you what it'll drop to. You can manually override this feature and run the processor at its full megahertz rating all the time, but you'll shorten your battery life.

If you look at power settings in screen saver properties there will be settings for both battery and AC power just need to set them all to never.

I've got Dell lattitudes with the Intel Speedstep stuff, and like the others have said, you can set it for maximum performance when on battery or AC. But don't expect much battery life if ou do. You can also customize the power settings as well.

I'm waiting on an IBM X22 PIII800 (just happens to be the tualitin core, at least the last one was) that does Wus in 5h20min.

Darn thing is on back order. All I can say to IBM is "I WANT MY LAPTOP NOW!". :frown:

It was supposed to be here on the 1st. Waaaahh, all those lost WUs for the week.....

Shotgun, which Thinkpad are you Getting. The T23 Thinkpad is about the fastest out there with the "M" cpu on a 133 fsb and 512 secondary cache. Sweet Laptop


Edit, 5:20 WOW.....Now Thats Fast......

5h 20min (I'm assuming that's the average) from a PIII 800 laptop? My 1GHz Athlon's best time ever isn't even that low... /me grumbles off looking for spare change so he can upgrade the 1GHz to an Athlon XP 1900+...

It's the average over 3 days that I had it running. It was (since I haven't got another one in yet) the fastest running ship in the fleet, even beating out the Netfinity Server average of 5h28min. per WU (for one CPU) which has Xeon 700mhz with 2MB cache. :Q

why do you think I'm making such a fuss over it being back ordered?
