The issue annoys many and may have to go away in future designs. Nothing's broken here and it has to do with it scaling back the clock speed when it can.
I have an HP DV5000z, with a turion ml-37, which runs at 2.0 gHz. Something peculiar happens when I right click on My Computer and select properties. Sometimes the processor speed comes up the correct 1.99 gHz, but at other times it shows 1.59 gHz. This happens totally randomly as far as I can tell. Anyone know why this happens? And I know it's not a bug in my machine, because this is the second dv5000z I have, the first one I had to send back because of a bad screen, and that one did the same thing. Anyways, anyone know why it does this? thank you.
