True CPU speed?

On my new PC the CPU installed shows up as an Intel P4 3.06Ghz and not the 3.2Ghz as stated in the specs when I bought it.

This is what the shop had to say:
"As far as I know it is the same processor. The clock speed can be adjusted, and we had it on offer as a 3.2GHZ (set to 3.2GHz) but have found that it performs better set to 3.06GHz, so that is how we sell it now."

On some motherboards you can adjust the multiplier. Say you have a 400 MHz bus and use a multiplier of 8 you get your 3200 processor. But if you take the same bus and use a mulitplier of 7.5 you get a 3000 processor. Now reality says the real bus speed is 200 so the multiplier should be 16 to get a 3.2 processor(3200). So if your multiplier is 15 you would have a 3.0 processor. Small variances in actual speed could get the 3.06 speed.Some motherboards will let you change the miltiplier and some won't.

Increasing the multiplier can also increase the processor running temp so there is no real improvement in processing power.This is especially true of the prescott processors that already runs hot with stock settings. Personally if i bought a 3.2 processor i would expect to get a 3.2 processor, not less, or a overclocked smaller processor.

I looked in your profile and it says you have a laptop so im guessing that is the one you are talking about...

Alot of the newer laptops by intel has this new technology called Enhanced Intel SpeedStep® technology. The system adjusts itself to use a lower or higher cpu speed depending on what kind of application or programs you are currently using. If your laptop isnt in use using alot of resources it will adjust to a lower cpu speed and this lowers power consumption for your battery/batteries so the batteries will last longer...

If your laptop needs the extra cpu speed it will adjust itself and use the ammount needed..


I dont know if your laptop has this technology but it could be the reason that your cpu speed is listed lower.

Your fsb may have been set lower by the company aswell if the tech said they do but who knows he might be telling you a crock of crap.

Here are the intel links that explain the Enhanced Intel SpeedStep® technology.

Sorry, the new one is a desktop.

MB: Asrock775Fire-eSATA2+
The CPU was supposed to be a Pentium® 4 (HT) 3.2 64bit power CPU.

Where would I find the CPU sSpec number?
