Pentium 4-M question

[t0rek]

My sis just bought a used Dell laptop. It has a Pentium 4-M 2.2 Ghz processor (Northwood), however using CPU-Z I noticed is underclocked at 1196.4 Mhz. My question is, how should I adjust the FSB and mutltiplier stuff at the BIOS to fix it at the stock intended speed? I'm asking because I don't know nothing about P4 specs.

Sounds like Speedstep at work, which all mobile Intel CPUs including P4-M support. I believe CPU-Z can misreport the clockspeed with certain CPUs with Speedstep enabled. CrystalCPUID should report it correctly, or try running an app that uses 100% CPU.

mmm, tested with prime95 with CPU-Z, is ok, with crystalCPUID is ok again, thanks Clements. BTW I went into the laptop BIOS a little, what an horrible thing a Dell BIOS is...

I'm a supossed to answer that? lain:

I don't think you do.

Forget it, it was supposed to be a joke ;/

It probably underclock itself to save battery life.
Isn't it very common that a laptop do that?

Yep, it is. Speedstep and PowerNow! underclocks the processor when it isn't at 100% CPU usage.
