BIOS update on 1.5 P4 / 2.5 GHz Celeron swap?

hello all,

i have a dell dimension 4300 and swapped out it's 1.5 Ghz P4 for a 2.5
GHz Celeron. the BIOS still shows '1.5 GHz P4' as the processor
present in the machine.

do i need to update / reinstall the BIOS?

thanks,
amc

See if the bios has a FSB setting which appears currently
set to 100MHz and set it to 166MHz. If it is listed in DDR
terms it might read DDR200 and would be set to DDR333.

That is if your motherboard supports 166MHz FSB, you should
read the manual to determine this or get the system specs
and report the chipset it uses.

If there is a newer bios available claimed to support newer
CPUs, it may be a good idea to update that but it is not
likely to automatically change the FSB setting. I wonder if
your board does not support 166 FSB and this is why you have
the wrong speed presently.

Boot into Windows and use this program to check the clocks.
The identity issue might be limited to the BIOS. What is
important, is that you get full performance in Windows.

If you are still having problems, post back the SLxxx code
on the box the Celeron came in. You can look them up here.

It is actually a 2.7GHz Celeron. Updated BIOS to most current. It now
recognizes Celeron 2.7 Ghz, but the L2 Cache is still 'unknown'.

Here's a screen of the results from cpuZ:

sSpec#: SL77S

the bios does not allow me to change the bus speed. the only option is
100MHz.

First, I have to apologize for chopping up your post. For some
reason, my news server won't let me post right now, claiming
I used a "bad word" in the body of the post. I'm forced to
remove portions of the post, to try to pass their "swear" filter :-(

That looks correct for that processor.

If you look here, it does seem to have an L2 = 128KB. So the
processor is a Celeron (Northwood 0.13u) 2.7Ghz/FSB400/L2=128KB.
Celerons are known for having a smaller cache. All is well.

Run CPU-Z and report back what speed it lists.
