overclocking-bus speed, multiplier and cpu voltage??

[Guest_imported]

If I have a 1.3 G celeron, I should set up the bios like
FSB 133Mhz, multiplier 10x right?
If I want to overclock it I might set like :
FSB 133Mhz, multiplier 13x or whatever I would like to
try but what does the core voltage of the cpu has to
do with overclocking? Can someone give me some
idea?

Off the top of my head! most Celerons are only 66 front side bus but the new ones (like yours) have finally gone to 100fsb, so to your question: 100fsb not 133 and times 13 to get your standard unclocked 1300 processor speed.
If you do intend to overclock seek advice on overclockers sites but don't go mad, take it easy, you may get 10-12% increase in clock speed but I'm no expert overclocker, one thing I do know is take it up in small increments, bit by bit, and make sure you have very good cooling. Martin Just trying to help, sometimes falling short, I am only human after all.

The basics are that you raise the core voltage to cure instability problems when you hit high Mhz. This, naturally, makes your processor run warmer, so you need a decent cooling system before your CPU starts to glow.

Another thing with raising core voltage - if you are determined to do this to squeeze that extra stability out of your already overclocked processor - less is best. Raise it the tiniest amount your motherboard allows each time you restart to check. It depends on how enthusiastic you are with multiplier and/or FSB settings, but a whole volt is a huge amount to most CPUs.

If you have a machine you want to overclock, start with the FSB first. Many processors won't allow you to raise the multiplier anyway, so this is always a good start. Again, less is best.

Hope this is helpful. CitrixEngineer@yahoo.co.uk

To be honest, I have no intention of overclocking my celeron.
I have only a 433 Mhz and a Asus P2B (440BX chipset that is
4 years old). I am just curious about raising the core voltage
as I have read a lot of these from the papers. Tks for all the
input and if I am ever going to upgrade my system (enough
budget) I would probably do it the usual way: change my
mobo and cpu at the same time.

Now you've posted your CPU/motherboard details, that does put a different light on it - I believe those early Celerons were very overclockable - especially the 300A, which, according to many acounts could reach 504Mhz stably.

Combined with your classic BX chipset, once the new system is built, I think I would be very tempted to overclock the celery!

You can't change the multiplier on a celeron. They're locked. You can change the FSB depending on the Board. If you have a 1.3 its a 133 fsb model (tulatin)

If you want some more info come on over. Don't raise you Vcore unless absolutely necessary!

I am confused again. Are you saying that even if I can set the
mobo's frequency mulitplier, the cpu won't accept it.
