Strange P4 3.0 showing 1.6Ghz

[wicked88]

right strange one here i have a P4 3.0 533fsb chip but when i install it in a motherboard (tried 2 diffrent ones supporting 533-800 fsb) its shows up in General system as a P4 3.0 but only 1.60 Ghz, any ideas. It came out of a Sony vaio (not a laptop but the all in one system) which says its a mobile P4 any ideas

does your board support multi unlock?

i've got the same problem with a P4-M 2.0 that only runs at 12x multi so i have to increase the fsb but then it will only boot at max of 133 so it reads as a 1.6

i know its not much help to you but at least you're not the only 1

yea i have a 3.2 chip that does the same i had to find a board that let me change the multi,

one thing that is good it runs at lower voltage and clocks very well

Most desktop boards can't deal with the speedstep technology so default to the lower multiplier of the cpu, in this case 16 so thats how you end up with a 1.6GHz cpu.

It defaults to 12 x 133 I believe.
