Do mhz fluctuate with used computers? Help!

[Jeremy24Philly]

Hi, I just bought a used IBM Thinkpad (I believe Pentium III)
with 386ram & Windows XP...I am confused however, because when I click control panel,
system, and get the systems info it says : 696mhz, then I clicked it later and it was 140mhz,
then i clicked it once more and it was 180mhz lol.

Is there a site where I can go to that will scan my computer and tell me everything about it?
If so, or something like this, if anyone could help me find it I would really appreciate this.  I cant
enter the model number or info because the seller took of the sticker *shrug*  Thanks in advance!


Thanks!!!!!!

What is the Model number and the machine code? THe machine code is a seven digit series on the botom of the machine like xxxx-xxx.

Then we can advise.

If it works, download and run Everest Home and make a report to copy and paste here for analysis. There may be some normal variants that we can explain.

Probably The FSB flucuation.Electrical flow and motherboards are not perfect.

They are however dog gone good!

Take for example my Aunt Drucella.

More than likely a Centrino chip and throttling down when ruunning stricly on battery power, but I wanted to ease him into that notion if he ever turns up again.

You have toyed with the lesson, Street1. These aren't the droids you're looking for.

See this: Variable CPU Speeds.  This is quite likely the reason for the variation.
