OC go7600, NHC & Nvidia PowerMizer? yes/no?

I have been scanning through the forums and picked up on the fact that the go7600 on the Hel80 is underclocked from stock. Or even if it's a lesser part the dif is nil but here's my questions.

1. It came to my attention that the go7600 has an option utility to control the power consumption, core and memory clock, called PowerMizer. It's rather basic I suppose, but has anyone used it and seen a noticeable impact on battery time deeming it worth while?

2. Is it possible to use this program along side what everyone is calling NHC? I know what it stands for, but I don't know what program is being refered to or if it's provided stock with compal computers. If it seems illogical to use both then is that because an NHC can also throttle the video core?

3. Is all this care about possibly saving battery and heat a waste if I were to manually OC the core and mem?... can both OC and power saving utilities work together for the times that I want to conserve, and allow max throttle OC when I game?

Sorry if this is redundant, but I didn't find my exact answers here or when i googled. Thanks , much appreciated

 

Some answers for you hopefully :
1. On battery, PowerMizer should automatically go to maximum battery anyway, so don't think you can play around any more and save battery time.

2. Notebook Hardware Control is a program you can download from the internet. Most people here use it to undervolt their CPU's. It doesn't have control over any GPU configurations as far as I know.

3. What I do is underclock the 2D settings (regular work) to conserve, and max out the 3D settings (which is the settings used when gaming). But I have yet to notice any significant battery time gain even with this method.

 

I see. Yes I think you can manually specify how PowerMizer handles on battery power.. "PowerMizer also allows notebook users to adjust system performance and battery consumption to their specific needs. For some users, consistently high frame rates in their favorite game or workstation application is a must; for others, such as frequent travelers on transatlantic flights, the longest possible battery life is a necessity." http://www.nvidia.com/object/feature_powermizer.html

And when you say, UC 2-D and OC 3-d you're doing that in the nvidia hardware control?

Edit: I have gathered this is something quite normal within the power utility.. good to know, but I'm surprised no real effect comes of it. I would think that battery life would have atleast some change, or why have the feature? Perhaps Bill Ny the Science guy, Mr. Owl or mr. wizard would know..

So, in summary to answer myself..the answer is Yes..all 3 ideas work together, OCing, Power Mizer, and NHC

 

I've been thinking along the same lines as the original poster. When I get my HEL-80 I'd like to leave it underclocked while on battery, but crank it up while plugged in (probably set to default clocks for the 7600, I've got a desktop that I can game on if for some reason some game doesn't want to play nice)

I'm assuming some Nvidia tool has "profiles" for doing this? I know ATI cards do, but I dont have much experience with NVidia.

 

well, from what i gathered you can crank the crap out of the processor, but power mizer does the same thing to virtually every nvidia go chip.. I'll see if i can find the page, but lets say it's roughly this ..there are three steps of optimization.. performance/ balanced/ efficiency Now if you leave your chip stock, or OC it.. that is your performace clock for mem and core.. seems pretty obvious.. but balanced and Efficiency are pre-determined always and never change.. something like 300 core/300 mem for balanced and 150 core/ `150 mem for efficiency. The balanced setting probably seems like small change on this underclocked 7600.. but the other chipsets take a larger dip

Ya.. i can't find it, figures.. well i hate to spread rumors so.. my numbers may not be perfect truth, but it's a rough idea.. anyhow the tech brief on Nvida's site says from performance to battery optimized is a savings of 25% (from like 30w to 22w).. not much really.. and for all that savings if your chip is locked to efficiency it offloads processing to your CPU. So.. I wonder if it really does much at all.
