Intel Celeron Overclocking Guide

Which Motherboards Support The New Celeron?

I already mentioned it in the first part (Celeron Performance Guide): It's very important to have a BIOS which supports the Coppermine-128 Celeron and you will need a motherboard which is capable of supplying 1.5-1.65V core voltage. Actual models (one year or younger) should be able to do this, but the older your board is, the smaller is the probability that it will do it. If you are not sure, please check the website of your motherboard maker.

It doesn't matter if you have a Slot-1 or a Socket 370 motherboard. As already mentioned, you will require an adapter board for Slot-1 motherboards. Usually, those adapters feature some jumpers, which let you change the CPU's voltage requirement.

If your board supports 75 or 83 MHz system clock speeds, you get some overclocking options this way. Please note that most adapter boards just have the voltage definition jumpers, but no voltage regulation unit! That means that you will not get more voltage options than your motherboard's voltage regulator supports.

Some older motherboards support down to 1.8 Volts core voltage and a few freaks are already running their Coppermine processors at this voltage. Generally this high voltage is not a problem, but the core will heat up much more. If you really want to use your processor like this in the long term, make sure you get the best CPU cooling solution you can get. Otherwise, you will certainly reduce the processor's life span.
