Overclocking and Undervolting Questions

Overclocking Questions:

1. Will overclocking the GPU reduce battery life under normal circumstances (ex. Not playing games)?

2. Will overclocking the GPU reduce battery life under gaming?

3. Is it possible to overclock a notebook CPU? If so, how?


Underclocking Questions:

4. What programs should I use to undervolt and how should I do it?

5. What limit should I undervolt to with the system in my signature?

 

1. I found no since it's the voltage draw that matter when consider battery life, as well as heat.

2. Based on above post, no.

3. Mostly depends on if you got a special OCable laptop. Usually no, but you can try with clockgen though, that's your best bet.

4. I prefer RMClock as it's more featureful and less bloated. How to do it: http://forum.notebookreview.com/showthread.php?t=124420

5. Depends on how much less power you want to draw and how much less heat you want to create, search the forums to see how other people are doing and judge from there to about where you should be able to get.

 

1. A bit.
2. Yes.
3. Yes if you are lucky to find Clockgen or SetFSB that is supported by your motherboard.
4. Notebook Hardware Control and RM CLock.
5. Lower 0,2V is a good start for the max multiplier.

Hm, notyou and ikovac have different opinions on whether or not overclocking the video card will reduce battery life under normal circumstances and under gaming. If anyone could clear this up, it would be awesome.

 

From personal testing, having my CPU UV'd to .950V on all multipliers I see no difference in battery life whether it runs at 1GHz or 1.66GHz. This I would assume carries over for GPUs as well.

 

Since my Gpu gets around 3-5 degrees Celsius hotter during overclocked gaming than non overclocked gaming I would say yes , it will decrease your battery life since your fan has to move faster and so on.

 

I don't really understand the point of gaming on battery, since your processor gets clocked down when you unplug it. Not sure if OC'ing changes that fact.

 

You can set it to High Performance and it won't be clocked down.

 

I thought the same thing but call of duty 4 is totally unplayable on battery , even with all power minimizing stuff off :S

 

I'm pretty sure you can tweak it, but if someone here knows how, it would be great.

 

Well Css is still playable , and so is Hl2.
Its just that Cod4 needs the max power of my comp or it wont work, oh well that game wasnt meant to be played on the go anyway.

 

If Powermizer, a feature of Nvidia cards, is enabled, then your computers Idle and low power 3D settings will remained unchanged, unless you change them yourself of course. I get the same battery life no matter what overclock I have unless I'm playing games. why play games unplugged? just have a profile to switch to while playing games unplugged.
