Increased FSB = Increased power consumption?

I am going to overclock my laptop after my thermal past arrives.

I will be doing the overclock by using a mod thats available for the celeron M and P M processors.

The mod tricks the mobo to think the cpu runs on 133fsb instead of 100 thus increasing the ghz.

Does applying this mod increase the power consumption of the cpu too, causing the battery life to shorten?(hours)

this mod does not tweak with the vcore so i think the power consumption will be the same.

Are celeron M just P M that didn't pass the inspection? you know, like P4 and celeron.

thanks
 
as far as i know, they are two different processors, i might be wrong though...
regarding the power consumption, it will be the same... after reading overclocking101 and some discussions in this forum, i get the impression that increasing the fsb won't increase the power consumption...

wait for someone else to comment on this since i might get the wrong impression... :D
 
didn't notice that he was talking about laptop...
this i what happened when i didn't take coffee in the morning... :D:D

yeah as firsttimebuilder said... don't overclock your laptop...
because laptop don't provide a good cooling for it to be able to overclock.
even if you put the newly acquired thermal paste...
 
Increasing the fsb may see a sliight increase of demand by the board not the cpu there. But the advice given by b3rt d4ni3l is a practical one since laptop are self contained units with the lack of internal cooling you would see on a desktop case with added and/or larger fans or water cooling. Laptops/notebooks usually sit on a cooling pad for gaming models to help keep temps down.

I will be keeping my toshiba laptop on the desk too with a cooling pad.

My laptop has been running at temp of 61c on half load and will restart all the time on full load. it does not restart on full load with the cooling pad running.

I opened it recently and cleaned out the dust in the cooling fan and now it is running 40c and maybe 50 on full load.

With the arctic silver 5 i believe it will be cooler then what it is now.

from what i read on line this mode will increase the temp maybe by 5 to 8c.

So i think it will still be better then 61c.

Thanks for your input but i am wanna try it.

Will post the result later.

thanks everyone
 
The higher the clock speed and higher the bus does make it produce more heat, and it may have more of a power draw, which is why faster processors have a higher thermal output.
 
You already noticed the lower temps seen when having the laptop on a cooling pad. The restarts you have been seeing are the overheat protection built into the board. OCing on top of that without taking the right steps will put you in a bad light there fast enough.

So not a good idea?

Guess i have no luck with over clocking.

Anyway, i am gona over clock it and see the results and i am gona take the mod off.

Need to apply the arctic silver 5 to it anyway.

thanks PC eye
 
OCing will see the temps climb so keep a good eye on them. You don't have the room in a portable for something like a Zalman CNPS 9500 there!
 
you could try modding the heatsink/fan combo for the board if you're serious about this. i think most laptops have the folded copper heatsink and a 40mm fan. theres got to be something better you could do, like a thin 60/80mm and a heatsink with tighter fins?
 
The fresh application of AS5 and keeping it on the cooling pad while running it are the two best things available at the moment. That will be the time when cpu temps will climb. So don't plan to keep ut running all day or night but run up the 200hrs. over a period of days to allow the silver particles to fully settle.
 
Doing this will increase your power consumption. Power consumption increases linearly with clock speed, and is proportional to the square of VCore. For maximum battery life, this is not a good idea.

Will do. I am just gona apply the mod and measure it with pcmark05 and i am gona take the mod off.

when taking the mod off i need to take the fan from the cpu. should i clean the Arctic silver 5 from the cpu and apply another layer?

thanks
 
Once you start OCing anything you are placing extra stress on the hardwares oced as well as pulling more power. You should listen to ceewi1's advice on this. The model there probably is far from the custom gaming rigs that would be better suited for ocing. You will need denatured or rubbing alcohol for cleaning the old paste off. Make sure whatever you use is lint free.
 
You will find that with AMD as well as Intel certain models will be far better then others for ocing in general. Usually those are not the lowest but the low to mid range models in a series. Why? They are on the same base. One good example for AMD was the XP3200+ being the highest model number seen at vendors while the XP3400+ was only found in CompaQs? Basically that was a pre-oced 3200+ so the manufacturers offer a faster model then you can buy for a custom build.

When oced the 3200+ with the seemingly "locked"? mulitplier would reach the 2.31ghz 3400+ speed. When backclocked it saw the XP2500+ speed and listing. The old 2500+ Barton core model was the ocer there. I wonder why? Different preset speeds on the same basic chip! The lower model simply sped up to the higher model's default speed or even a little over at times. Gee? Don't you wonder if Dell or HP or someone already has an E6900? while everyone looks over the E6800.
 
Intel for the longest time was focused on cpu clock speeds while AMD slipped past them performance wise by focusing on the fsb. For gaming AMD held the performance lead for the longest time until Intel came out with their newest line up. For ocing the old AMD T-Birds were noted for this along with the Socket A Semprons. The best ocing was always seen in desktops however not portables with the confined space there.
