I purchased the Celeron 400 about a year ago and It has led a good life. It has tried to play me games and let me draw graphics. The Celeron only cost me £50 this at the time was a bargain as the fastest out was a 500. I have now overclocked it to 450 and it quite happily performs. I did try 500 but it sort of went a bit wonky so I will leave it there. I recommend this processor to anyone who is after cheap performance as now you could probably pick one up rather cheap. Although the higher processing speeds are now becoming cheaper.
Intel released a new crop of Celeron processors based on the 0.18 micron technology. They share the same core the new Pentium III. 0.18 micron technology means most of the CPU is capable of 800Mhz or above. With this in mind, I would like to push the Celeron 566 to above 800Mhz. The 566 has a multiplier of 8.5 with FSB of 66Mhz. By simply changing the FSB to 100Mhz, we are asking the CPU to run at 850Mhz, if it is capable of doing this. I used Abit BH6 with 128 Mb of generic PC100 RAM. Besides the CPU I need a socket 370 to slot 1 convertor as well. I used Abit's Sloket III. The system ran stable at 1.85V core voltage. A bit high but still within spec. After some bechmarking using Quake III, I noticed even at 850Mhz, the Celeron is still beaten by Pentium III 700Mhz. So there you go, for less than £120, I upgraded my system from Celeron 450Mhz to Celeron 850Mhz. Great savings!! Good luck.
Wow, I just bought one of the new Celeron 566 processors and it runs perfectly stable at 850Mhz!! This has to be one of the cheapest ways to upgrade your current pc to something with much higher performance at the moment. Since the chip fits an FC-PGA socket and I have an old Abit BE6-2 Slot one board I also had to buy an Abit sloket converter but this was really easy to install and the performance over my old celeron 366 is amazing.
O.k i have seen the light, and it can only be with a celeron processer, coming ing far far more cheaper then an AMD athlon or a PIII but still a little higher then the AMD k-6 range. But the quility of this chip is amazing. This can be seen by the power of the chip when trying to overclock. A celeron 500Mhz chip will actually run at 666MHz !!! At a plausable temperature too. This is most easily achieved by obtaining a ABIT B** series board due to the fact of they are jumperless and alls you have to do to overclock is change some easily manipulated settings on the BIOS, restart and your away... Excellent and easy for anyone to do. All the cooling you will need is just a normal celeron heat sync. and fan :-)
