Evo N1020, 2.4 cpu running at 1.8. Why? [ Edited ]

Hi everyone.  I'm new to this forum malarkey, so bear with me if I slip up somewhere.

I've just replaced the cpu on my Evo N1020v, changing from Celeron 1.5 ghz to Pentium 4 2.4GHz, which I understand from HP support is supported by my m/c.  On start up and entering the bios I see it's recognised, but running at 1.8 ghz.  There appears to be no means of altering bus speed in the bios.  How can I get it to run at 2.4 ghz ( or can't I) ?

All help and advice greatly appreciated,

You put a 133 fsb cpu on a 100 fsb board so the speed you are getting is 2.4/133 x 100 =  1.804...

There is no way to change the bus speed on that unit as you have seen, which is true of virtually every laptop ever made.

The Celeron motherboards are a different unit than the ones used with original P4s.

You are still way better off than with the 1.5 Celeron and the processor ought to run nice and cool since it is essentially underclocked. I suspect you will not have Intel Speedstep however, and your battery life is going to be dreck.

Thanks for that Huffer.  I thought when HP/compaq support said the 2.4 was supported by the board it would run at 2.4, and the book says it can be used too.  Just shows you, you can't trust anyone today.  Would you happen to know what cpu i can fit here that will run faster than 1.8Ghz ?  If not, I suppose I can live with it.  Thanks anyway for your reply.

I think the only thing you could do is find a faster Celeron, but a 2.2 Celeron would be about equal to a 1.8 P4 so I would not bother.
