Undervolting i7 CPU and/or GPU?

I'll just start off by saying I have zero solo experience doing any voltage or clock manipulation. I'm just looking to get some cooler temps and battery life out of my notebook. I've searched NBR and Google with very little luck. It seems very few like to undervolt their GPU, and the only software I could find is a 3 year old program called ThrottleStop 2.99.9 (found it here: http://forum.notebookreview.com/del...ttle-issue-investigation-152.html#post5637647) but I'm stuck there. I have HWMonitor to watch temps and ran Orthos to stress test (which only worked on 1 core, or rather 2 of the hyperthreaded cores in my i7 2670QM). Any guidance would be greatly appreciated. Thanks in advance!

 

You don't google much, huh?

(or look at the bottom of the first page of threads...).

TS now on v5.00.

 

AFAIK you can't undervolt the i7 CPUs.

 

That's right. All the i-core CPUs have no facility to set a lower voltage per multiplier. Nor is it possible to modify VID pins on the voltage regulator since the VID data is serialized.

There is however a way to get power savings or temperature reduction. Do that by set a lower max multiplier in Throttlestop or set max % processor utilitization to a lower amount in the power control panel. That will then run at a lower voltage under full load.

 

What the heck happened to nando4?? As for his suggestion, might as well just get a slower CPU then. However, the trade off is that CPU intensive tasks will run for longer and in the end the overall power consumption will not have changed. For non-CPU intensive tasks, it won't make a difference since it will not hit the maximum frequencies.
