why system properties dont show correct CPU speed?
I am using acer travelmate 370 notebook.It's a 1400Mhz Pentium M Centrino Processor.BUt when I open System Properties by right clicking on My Computer,it shows my CPU info as PENTIUM M 1400MHZ and below it says 598MHZ and the line below it shows the RAM.What I can't understand that why it shows 598MHZ?I checked the notebook of my brother,he's got a 1.5GHZ Centrino,his system properties show Pentium M 1.5Ghz and under also 1.5GHZ.Unlike my notebook.I can't understand why in my notebook it doesn't show 1400MHZ in the second line? Any body knows?
Which vesion of cpu-z are you using???The core speed is the correct value. Intel Pentium M processors use advanced Intel speedstep technology which decreases the clock speed to ~600MHz and then increases as and when needed to the highest speed depending on the cpu model.
If you want the cpu to run at 1400MHz all the time, change the power setting from portable/lapop to always on...Do remember that this setting consumes most power and battery life will decrease.
To change power setting:
Control Panel(classic view)|Power Options|change power schemes.
Your CPU has an upper limit speed, and a lower limit. And the clock speed changes as the need changes (clocks up or down). If you want to double check get CPU-Z (google it). This will tell you real time at what speed you are running. You will notice that if you load your CPU it will clock up and when the system is idle it will clock down. This is done to save power, and limit heat generation

[br]Thanks for the reply.It solved my problem.I just modified power options to always on and now I get my Cpu Core speed as 1400MHZ  You are great.Any more tips for me?
Now your battery time will go down. I'd leave it at the original setting. The processors do a good job of throttling up and down based on cpu need, and that saves you battery time.
You can modify your power settings to ALWAYS ON when you're plugged in to get the best of both worlds.
