Two mhz number on "my computer"?

[KlapsKali]

Hi, first my english is not that good, but please continue reading. If I click (right) on "My Computer" then choose properties and generell there are two mhz numbers. I guess the first one is the maximum mhz of my cpu, but what does the second one mean? Sometimes the second one shows 2.8 and sometimes 1.6 even if my notebook is on ac power. I downloaded a tool from Intel (Frequency ID Utility) this tool always shows 2.8 (currently frequency) even when "my Computer" shows 1.6. If somebody understood me and knows an answer please reply. Thanks for that and for reading this far!

Best regards

Can you confirm what chip you have - Pentium-M, Pentium or Celeron?

Sounds like you have a CPU which has Hyper Threading.

I have a Mobile Intel Pentium 4 CPU 2.80 GHz. What is Hyper Threading and where can i check if my cpu has that?

[KlapsKali]

According to the Sandra benchmark my cpu does not have hyper threading...

The easiest way is to go to TaskManager and click CPU performance - if you can see 2 green lines you have hyperthreading

As you said if Sandra doesn't have it then you don't have it.
I have no idea why you have two figures.

It may be because the CPU is going into a lower power mode, thus helping to preserve battery life.

I thought that too. But it also happen on AC-Power.

What have you got your profiles set to? You can set the AC power to slower clock speeds anyway I think?
