XP with the default power management profile (Office Desktop IIRC) doesn't vary clock speed at all. And since the stuff I read said something about the OS not clocking back up when needed, yadda yadda, paranoia! First, the stock speed is ~3.2GHz, so why is it 3.4 in XP? Second, why is it 1.6 in W7? This, combined with the stuff I read, lead me to believe it was the OS which mainly responsible for controlling clock speeds. I did not OC, simply loaded the XMP profile for my RAM, and reduced ram Voltage from 1.66 to 1.64 because BIOS warned me about going over 1.65V. In XP, CPU-Z showed my clock speed at ~3.4Ghz, while in W7, my clock speed was at ~1.6GHz.

One of the reasons I was meddling in BIOS was because I noticed different results in Windows XP Pro 圆4 SP2 and Windows 7 Enterprise 圆4. So I guess that is my next question: Does the OS communicate via SpeedStep, or interact with SpeedStep in any way, or is it all in the hands of SpeedStep when it comes to turning the clocks up or down? As I understood it, it was the OS that was responsible for NOT clocking up when necessary, and after your explanations, my guess is either I misread, or OS controls SpeedStep.

What I read was that the OS sometimes screwed up when it needed to put the clock speed back up, not SpeedStep. I wish I had the links on hand so I can post them here or at least re-read them. (Though it's basically the same mechanism). RicDavis: He's talking about Speedstep clocking the processor down when it's idling, not Turbomode clocking it up when it's busy. Even if you are dedicated to maximizing your energy usage, you gotta love fans running at 20% speed most of the time. Leave speedstep on and enjoy components that run cooler, don't make as much noise and conserve energy. :EDIT: Looking at the docs, it seems Enhanced Speedstep introduced with the Pentium M can switch states in about 10 microseconds - that's 10 millionths of a second! So yeah, don't think you'll notice that. Speedstep is able to change the processor speed damn near from cycle-to-cycle, which means to the user it will happen so fast as to be instantaneous. I've read that sometimes it stays underclocked when more speed is needed, so rather than worry about that and constantly monitor, I just wanted it at 100%.ĭon't worry about it.

The reason I wanted it at full speed all the time is basically paranoia.
