Vista Changing my Proc Speed??

Hi All,
I've heard of speedstep and as fas as I know, I've never activated it. But if I leave my PC on idle for a while with no activity the processor speed drops to the default speed versus my OC speed. In the Power Settings I have my monitor to turn of after 5 minutes with my HDD never turning off.

Any idea what might be happening here? I really appreciate the help.
 
It's called the energy saving feature now seen in both Intel and AMD models alike while the older P4s and single core AMD models on boards upto AM2 would be running at one constant idle speed. The system idle process seen in Windows prevented the older cpus from simply running full steam ahead like seen when staying in the bios setup too long.
 
Forget everything your read in post 2, none of it is right. The energy saving feature hes talking about (is) either Speedstep with Intel or Cool&Quiet with AMD and with AMD it didnt just come out with AM2 its been around since 2004.

More than likely Speedstep was enabled in your bios by default, you just need to disable it.

AMD's Cool&Quiet wasn't fully implemented until the AM2 boards arrived. It was first seen on 754s then on 939s where the X2s and FX-53(single core) were the only models for use there.

Speedstep is built into some of the Intel models. Besides seeing that it is disabled in the bios you also have to go into the power options to change the power profile to performance. For XP that would be the Always On option.
 
You are such a noob. AMD even had PowerNow even before Cool&Quiet. And Cool&Quiet worked on almost all single core Athlons, the Sempron was the one Cool&Quiet did not support and it is even supported now!
 
In part I have to stand up for PC eye here.

In Vista, the Intel Speedstep driver is built in as part of the OS. There's no way to remove it. Vista can, and will if you let it, clock the processor according to it's needs. The only way to override that is in the power management options unfortunately....

HOWEVER...

If you turn Speedstep and C1E off in the BIOS, regardless of what Windows wants to do your CPU clock will remain at full speed.
