SpeedStep Not Enabled

I've just noticed that my new notebook's clockspeed is stuck at 2.0GHz (I have a Dell E1505) when I'm one battery power. Is there anyway to enable Speedstep, so I don't have my CPU running at full all of the time? I've already checked my BIOS, but I don't see the option to enable it. Any help would be greatly appreciated.

 

go into the control pannel and then into power options. your comp is probably on always on or something like that. change it to home/desktop and it should step down

 

As far as I know, "Home/Office Desk" doesn't enable speed step. You should have it on "Portable/Laptop"

 

On my E1505 when on "Home/Office Desk" setting, my CPU is full speed when on AC and steps down to 1Ghz when on battery. I generally keep it on this setting because when on AC, I want FULL SPEED!!

 

Thanx for the correction.

There is no reason to want your CPU to remain at max speed 100% of the time, even when idle. What speed step does is throttle your CPU speed as the performance demand changes. And the throttling response is pretty fast, on the order of miliseconds, so no noticeable difference. (when you need it, your CPU will be as fast as can be )

Enabling Speed Step all the time will decrease your power consumption and reduce your heat generation. It is quite effcient and Intel's last and future generations of desktop CPUs have speed step for that reason.

 

Some firewire devices get unstable with speedstep enabled.
To disable speestep simply set the power option to always on.

 

I've tried all of the settings in my Powermanagement, but Mobile Meter still reads out my CPU speed as 2.0GHz. Is Mobile Meter not functioning properly? Does it not work with the new Core Duo CPUs? If it doesn't work, what programs could I use to get an accurate reading? I'm sorry for asking so many questions!

 

Right click on My Computer and select properties. Your processor speed will be shown for that exact moment. It's definitely not the best way to check speeds, but it will definitely work for a moment in time.

 

Mobilemeter does not display CPU speed correctly.
It shows 1.7GHZ on my 1.66GHZ core duo...
Use NHC

 

OK, I've installed The NHC application, but I can't find it in the Admin. tools of the control panel, where should I look?

 

Go to Program files and look for Notebook Hardware Control in your local drive(c drive).

 

You can also use CPU-Z it tells you real time the CPU speed, multiplier setting, FSB, and voltages.

 

I checked with CPU-Z b/c I couldn't find the Microsoft program. Anyways, I found that my clock speed is at about 1ghz while idling (both cores). Is this where it should be at? I thought it should be somewhere near 600mhz, but I could've made a mistake.

 

1GHz at idle for the Core Duo's is accurate. The idle speed of 600MHz was for the 400MHz Pentium M's. Intel increased the idle speed as and when they felt they could get the same low power consumption at a higher speed.
