Topic: 12x multiplier on Battery?

is there any way to stop the cpu multiplier from halving when i take my n10 off AC? i'm getting a 9-cell battery so i don't think i need to conserve battery life so much, and I'd like to be able to game and watch movies on the move.

Re: 12x multiplier on Battery?

i think draves or dark jeric just adressed this to some extent search and look it up, it may have been disabeling this during stress testing for better results, not sure if it can be done all the time, i bet they can help.  couldn't you run it in a higher performance mode when on battery either through windows or p4g (do your own custom setting)

Re: 12x multiplier on Battery?

It's important to note that the multiplier's halvation is not set in stone. The fact you see your multiplier (and logically your CPU speed) halved is just a power-conserving procedure Intel calls SpeedStep. All it does is monitor if the CPU is actively being used, and if it isn't, it puts the brake on the speed decreasing the power draw.

As soon as SpeedStep notices the CPU is being used again (for example, while gaming or watching movies) it releases the 'brake' again and your CPU gets back to its full multiplier and speed. So it conserves power while not taking away any performance.

There is however one area where SpeedStep can get annoying, and that is OC'ing. SpeedStep usually lowers the multiplier and the voltage as well, but when you run OC'd, your halved clock speed is also higher (you OC by increasing the FSB, while SpeedStep only affects the multiplier). If your Atom chip can't cope at that higher speed with the lower voltage, it will crash. Since there is no option in the BIOS to turn off SpeedStep, you have to use a workaround. This workaround is called the HLT Command, and is a process integrated with RightMark CPU Utility. What the process does is trick your Atom and OS into being 100% loaded (while not being stressed at all), so SpeedStep doesn't get a chance to hit the brakes  wink

Don't make me "touch" you :-D

Ah, I thought it was asus trying to save me battery power. Hadn't run HLT on battery before, worked fine, cheers darkjeric!
