how to turn off intel's speed step?

Dell E1705 with the T2400 core duo

I thought you could disable it in the BIOS and there is an option to turn it off. well I did that several months ago and haven't thought of it since. well last night I was doing somethign int he BIOS and noticed the CPU seed was at 1GHz. WTF??? I double checked that speed step was disabled, and it was. it was then that I noticed that the description of the off setting is that the CPU is underclocked to its lowest setting when speed step is off.

OK so how do I get rid of speed step and keep it at 1.83Ghz?

on a side note, the CD and C2D architecture is absolutely awesome, to be doing what I do with the CPU running at only 1GHz, just....**** lol

 

The only way to do that is to set the power schemes to 'Always ON' for the notebook. That will keep it at the highest multiplier.

But I must ask: why are you worried about it? The processor will clock back up whenever the power is needed...it was designed to operate behind the scenes without you noticing any hits in performance.

 

I had prior problems with cool and quiet with my AMD desktop, and I am now using the laptop at a desktop till I build my new desktop and I just don't like it for some reason. yeah, I know, not a good reason lol thanks!

 

Well, I'd suggest you try it out for a while. If you don't like it that's cool...but processors have definitely made some major improvements. Even the Cool'n'Quiet AMD stuff works perfectly fine now.

You laptop will probably run quieter with it enabled.

 

I would say keep speed step "enabled" in the BIOS and select the windows power scheme "always on". Give that a try.

 

I won't let anyone talk bad about Intel's Speedstep! It rocks definately. When I am gaming the CPU runs at full performance (NHC) and while I am surfing it runs at 800 MHz and stays cool and quiet.

Download Notebook Hardware Control to control it on the fly. Great program, a real must for notebook users.

 

Don't disable SpeedStep - it's quite aware of what you are doing and will spool up to higher multipliers instantly should it need more power. SpeedStep, in addition to saving power and extending battery life, also keeps the notebook cooler.

 

Yea, speed step is excellent. My notebook is always throttling when connected to AC, and on max battery life when with battery. I love speed step for notebooks!

 

If you turn off speedstep, the processor will run at the lowest speed possible for it to run.

I got a Centrino 1.6 Ghz Asus M6ne notebook.
Full speed runs at 1.6. Centrino controlled during usage with the ac adapter.
When i turn off speedstep it runs a 600mhz no matter if the ac adapter is connected or not.

Conclusion there is no way to turn off speedstep without losing speed.

 

Intel's versions have worked well since the PIII-m and Dynamic Switching. Speedstep is worth leaving on for sure.

 

i think i have some issues with speed step, here's the case: i ran NHC's stress test after undervolting, and it's supposed to stay 100% load all the time. But i look at the graph, and it shows that the CPU does clock down to 1Ghz (for one second i guess) once in a while, which i blame for speed step. I really don't want it to clock down when it's not supposed to. Anyone's seen the same thing?
