Celeron Overclocking:

The Celeron is my favorite chip to overclock. It is amazing how stable these chips are at high speeds. Ok well lets get started!

Celerons ate stripped PIIs. They have a forth of the cache of their big brother PIIs. They have 128K vs. 512K. But here's the thing, they run their cache at full clock, where as the PIIs run theirs at half clock. This means that if you have a Celeron 300A the cache runs at 300Mhz. Where if you had a PII 300 the cache would run at 150Mhz. Please note that their is a difference between the Celeron 300 and the Celeron 300A. The As are better! They stopped making the plain 300 because they lacked power. So now all Celerons are As, just be careful when you buy a Celeron, make sure it's a A.

Ok to overclock the Celerons you need to adjust the BUS speed. You can't change the multiplier, Intel locked the multiplier (those ASSHOLES) no matter, all you need to do is adjust the BUS, so if you have a 300A (66x4.5) pump that BUS on up to 100(100x4.5) is a 450! WOW!!! Now wasn't that easy? Yet another note, not all Celerons will be able to make this jump, the 300s are the best and almost all of them reach 450, they even normally hit 464(103x4.5) and a few even hit 504(112x4.5) But the 366 Celerons don't all make 550(5.5x100) Some do some don't. With millions of transistors not everychip is alike, and therefore you can't expect your chip to make the exact speed you read about some guy online was able to hit. But you can help improve it's chances, by buying a BIG FAN. My favorite, and in my opinion the best fan, would be the Glacier 4500c w/Arctic Cap. goto www.net-n-dude.com to see it. It is a beast, 4 fans and two heatsinks. Also when you eventually buy a heatsink and fan it is an EXTREMELY good idea to get some thermal paste. I say this because the chip has tiny microscopic fractures over 99% of its surface. when you apply this paste it fills thosetiny gaps and and sorta of makes the heatsink and chip one. When applying this thermal paste, apply as little as possibe, to much can be worse then too little, or even none!

There is also software that can help keep your CPU cool! My favorite is CPU idle, which you can get at http://cpuidle.home.pages.de/ This is an extremely good program and can keep your CPU up to 10 degrees C. cooler. It disables the CPU when it's not needed. This can increase stability and increase the CPUs life span. The only bad thing is, is that it doesn't do anything when you run a CPU intense application, because the whole CPU is needed.

Some info on RAM, if you plan to hit that 100Mhz BUS you will need to buy some PC100 RAM, I recommend CAS 2, because it is more stable,and better at hitting those 100+Mhz BUS speeds, like 103Mhz and 112Mhz.

A Little Help at Trouble Shooting and Testing Stability:

Ok to know weather or not your chip is stable run a game like Quake II, or anything else that has a looping demo and requires 100% of the CPU. Run it for like 5 hours, and if your computer doesn't reboot or lockup, ur OK! If it does try the following things:

-If you haven't already, apply thermal paste

-Take off your case

-Add a Chasis fan(only like $10)

-Tie up your IDE and power cables, this can improve air circulation
