Dynamically underclocking Samsung q310

I'm not sure if this is the best sub forum for this, but it seemed better than the alternatives.

Is it at all possible that I will be able to underclock this laptop when I am running on battery power? IT would be useful, as it is unlikely that I am ever going to be using all of its processing power. Perhaps even underclock just the graphics card.
I am guessing no, because I can't find any obvious way to perform this operation, and when unplugged in power saver mode dxdiag still reports 2.26ghz on the processor.

Also, completely unrelated, is there any way to disable Samsung recovery solution opening itself on startup? I really wish that it wasn't included to begin with. I have looked in both places in the registry where startup programs are kept (leaned them out too), and the startup folder is clean.


Thanks

 

Welcome to notebook review,

You can dynamically underclock your processor.
Download CPU RIGHTMARK Clock Management, (RMCLOCK) from cpuid's website.

In their you can go into the profiles menu and select for your system to run in the "performance on demand" profile. That way your cpu can dynamically switch between its highest and lowest multipliers to maximize battery life.
This can be seen in the undervolting guide flipfire made. You should also try undervolting to decrease the thermal output of your cpu, and helping to increase battery life.

To shut off the Samsung recover stuff, go to the start menu or start orb depending on the operating system, and than go to th run command.
Type in MSCONFIG.
Than go to the startup tab, and find the samsung tab, and unclick it. It will not appear anymore on startup.

However, while in MSCONFIG, go through the startup, and services tabs, and shut off all background processes, application, services and programs you do not use. That will free up harddrive, cpu and memory usage, thus making your system run faster and more efficiently.

Your laptop is equiped with the C2D P8400, which should be able to downclock when on battery or when you are running light application such as word processing, email client, listing music and the like.

Your OS is Vista. I think you need to reconfigurate your Power Managment. It must be set to 'High performance'. You should set it to 'Balanced' instead.

This is a link on how to access power managment under Vista:

Try this first. If it works you could also try RMclock, though RMclock is more adequate to reduce the heat decipation and increase battery life (how much increase will depends on lot of criteria).

 

What K-T said but if the choice for "max battery" that will keep it downclocked always. I use Notebook Hardware Control Monitor. I use the "dynamic switching" K-T mentioned when on AC as a heat control measure. It works well. If I need more power it switches with no delay. If I am surfing the WEB on AC lower clocks lowers heat and that is undervolted not by me per se but the AMD power now lowers when running at 800Mhz. Best of all worlds. I assume Intel will be similar.

 

Thanks for you help.

Just to make sure, RMClock won't void my warranty?

Also, in power management I seem to be missing the balanced profile. In its place I have Samsung optimised. I was also unable to find the controls for underclocknig my cpu in the power management settings.

I created my own profile (and in the process discovered a multitude of others) In here I set the maximum processor state to 64% (while on battery) and the minimum to 5%. As I understand it this should work. How am I to know if it is or not though? I m presuming now that DXdiag will not give on the fly information.

 

rmclock will not void your warranty and undervolting is completely safe. Thousands of people here have used RMCLOCK, for undervolting and setting dynamic throttling of teh cpu. It works great, and if it helps I use RMCLOCK for over three years on numerous systems.

You can set the actual throttling of teh cpu in the profiles tab.
Just set the number of multipliers you want the cpu to run at.
To figure out clock speed, take the FSB of teh processor and multiply it by the multiplier to get clock speed. EX: 11x multiplier on 200MHz FSB = 2200Mhz.

266 x 8.5 maybe?

 

Thank you for the quick reply.

Hmm, I think that I will just stick with vista's controlling for the time being.
RMClock seems to have little documentation. However if battery life eery becomes a serious issue for me I will probably return to this neat little program.

The problem with it was that I wasn't sure how well it would integrate with my power profile. I have made my own profile which has all the boxes set to the maximum power for plugged in, and it has them set to low power for when I am on the battery.
Will RMClock be able to have a variable cpu when I'm on battery, limited to 50% throttle. but when I' plugged in, have it set the cpu to full throttle?

Thanks.

Also, when I created my profile, I based it from the power saver mode. when I use it plugged in it warns that I may not be getting the full potential out of my system. Is Vista being smart and evaluating the setting I chose, and telling me that I didn't set them all to "high" for when I have it plugged in. Or, more likely, is Vista just reading a tag that was copied over from the power saver mode that I based mine upon.

Thanks again.

 

You can make any throttle options you want with rmclock. It may be a little confusing to do at first, but it is really pretty simple to do. I am sure people here can help you figure out how to do it.
If you make a profile through RMCLOCK, it will override your vista power options.

I think that I am getting the hang of the program now. However I am unsure about what will happen to all the other settings of my windows power modes.
For example if I am using RMClock and I am on battery. Will it go to sleep after 5 minutes, as per my profile, or will it take some other value being set?

Thanks again.

Also, I was unable to find the recovery solution anywhere on those tabs.

 

Ah, It turns out that RMClock doesn't yet have support for the Montevina platform. I think that I will just wait a while for it to be supported (is it likely to happen in the near future?

Thanks

EDIT: Whoops, sorry for the double post.
