Overclocking Celeron 500mhz

[flywheel]

I've read somewhere that the Celeron overclocks well. How far should you be able to overclock a 500mhz Celly and keep it stable? Do these chips have a very serious heat issue when overclocked? As you can tell, I'm not very knowledgeable w/ Intel, but I see a lot of modded cases out there with Celerons and wanted to do some experimenting.

Is there any particular mobo that overclocks these CPU's better?

You can probably get it up to 563MHz at 75MHz FSB if you have that option on your motherboard. The Mendicino Celeron could go between 500 and 600MHz MAX. If you had a Celeron 366 (same core), you could probably get that to 100MHz FSB (550MHz). Much beyond 550 is very difficult.
The newer Coppermine core Celeron will normally overclock to between 850 and 1000MHz. That means changing a 566 to an 850 is as easy as raising the core voltage to ~1.8v (+/-0.1v) and bus speed to 100MHz. But that's no longer a feasable option for new equipement because the 850 only cost $3 more than the 566.

What's the frequency, Kenneth?

thanks Crash. I see that now. I didn't know they changed the core of the chip after I got mine. Are all of the ones at 566MHz called <b>Celeron II</b>?

Yes, but that same CPU can be called other things, such as FC-PGA, Coppermine, etc. The main confusion is at 533MHz, at which speed both were available.

What's the frequency, Kenneth?

that 533 was available in 533 and 533A MHz, just as 300 and 300A, more recent P3 1.13 and 1.13A and P4 2.2G and 2.2A GHz! that makes it all confusing for most of the people.

Then, Celeron3 (Tualatin is here) and Celeron4 will soon arrive (Williamette P4!)

The 533A was the PPGA methinks, while the 533 FC-PGA would have been called an E if it were a PIII instead of a Celeron (since it uses the Coppermine core).

What's the frequency, Kenneth?

but there wasnt any P-III with 66 MHz bus to make a 533 MHz processor, it would have certainly named as E, but E actually meant that it had a ATC (Advance Transfer Cache), that running at full core speed (but only half the size), Celerons still had the same amount of cache but it actually was an ATC! A suffix 'B' indicated that it also had a bus of 133 MHz (and obviously lower multiplier!)

There was a Celeron II 533 (FC-PGA) and a Celeron 533A (PPGA), these are the processors that caused the confusion at 533.

There was also a PIII 533EB, but that ran at 133x4.
