I have a P4 1.6 GHz processor in my old computer.I just got a 2.4 processor to replace the 1.6.When i installed it,i checked in the My Computer/Properties and it says 1.8 GHz.Why is that? Thanks


Pentuim(R)4 CPU 2.40GHz
1.82 GHz,512 MB of RAM
 
It's possible the hardware technology from that far back can't recognize the full speed on the newer CPU, or it's just a case of EIST kicking in (though MC/P usually lists the full value in that case). I'd download CPU-Z; it's a program that will display your CPU clock speed in real-time and see what it says.
 
Hey thanks for the fast reply! I downloaded it and it says core speed:1816.2MHz.Is there anything i can do,or am i outta luck?
 
I had a look at the list of P4 CPUs on wikipedia, and all 1.6GHz P4s have a 100MHz quad-pumped FSB (400MTs) whereas all 2.4GHz models have 133MHz quad-pumped FSB (533MTs). It could be that your motherboard's FSB is only rated at 100MHz (400MTs), which brings the CPU speed down to 1.8GHz (100/133*2.4.=1.8).

Whether there's anything you can do, depends on your motherboard. What mobo do you have? IT might be as simple as going to BIOS and setting the FSB frequency manually, or there might be other obstacles like no OCing options, mobo simply not able of handling 133MHz FSB, your PCI/AGP buses being unlocked and so on... but if you could post the make/model of your motherboard, that could help a lot.
 
Probably not the case, but just throwing it out there anyway, what is the name of the CPU? Look in CPU-Z, first tab, first box. If you bought it second-hand from someone, it's possible they were misled as to the actual clock speed.
 
Not necessarily... according to the link StrangleHold provided, that mobo can handle 533MTs FSB... which means that as long as the CPU really is 2.4GHz, it should work.

Did you try manually setting the FSB in BIOS?

As a last resort, you could try updating BIOS, but I'm not entirely sure as to how to do that for the board you have.

It's possibly a bit more complicated than that, which was already stated in hack's Post. Really now, why regurgitate info that was posted nearly 30 minutes prior?

isnt it always best to start at the start or no?

yeah i restated what has been said already, but my post was a bit more direct, because i am unsure of the OP's computer knowledge. so i put myself in his place and decided that hackapalites post might confuse him.

and if the problem IS more complicated then that then great. BUT the most simple thing to do is raise the fsb. if it works then guess what? problem solved! yay! :rolleyes:

oh and lookie here, i read hackapalites newest post and somehow, magically, what is the advice? raise the fsb because as far as we see thats the only problem.

Please don't use wikipedia as your only source unless absolutely necessary (ie there are no others). There are many 2.4GHz Pentium 4s that use a 400MHz bus. http://processorfinder.intel.com/Li...2103,2841,483,1077,49,&ProcFam=483&SearchKey=

You aren't necessarily wrong though, in fact, I think you probably have the problem pinpointed.

I went through all the options in the bios,I cant find anywhere where i can change the FSB. Heres the P4 i have http://processorfinder.intel.com/details.aspx?sSpec=SL6RZ#

If thats really the processor they sold you it should work on the board. The only reason I can think of it having problems is that its a HP board and the voltage and FSB are not correcting itself. Since you cant find any bios options to change them. As far as not adjusting the voltage and FSB it could just need a bios flash, if you can find one, to recognize the processor since its a newer model. You would need the model number of the HP it came out of.
