You may have seen my other post yesterday about fitting the new Sempron processor because I couldn't get an XP2500 Barton any where. Well this morning I decided to try and overclock it even though it isn't my computer. The standard specs for the Sempron 2400 are 333Fsb with a multiplier of 10X. This gives it a clock speed of 1.66Ghz. I went into the bios and raised the Fsb to 400, saved and exited. To my surprise it booted to windows staight away, no fuss,no bother. I defragmented the hard drive to give it something to do and then played Quake 3 Arena for twenty minutes. Quake actually loaded slightly quicker than it does on my Barton. It's now running at 2.0Ghz with no other alterations other than the Fsb increase. After playing Quake I checked the cpu temp with Asus probe and it was reading 38C. [bold]There are no case fans in this system[/bold]. The 2.0Ghz that this 2400 is running at is the same as the Sempron 2800 which was £36.00 more expensive, which was why I didn't buy it. All in all this a cracking chip and another overclockable gem from AMD. I'm so impressed with this processor that I'm going to try overclocking it a little more later. I'll get back to you with the results. This chip is sooo fast for what's meant to be a budget brand. I'm sure others will have a different opinion but it's well worth the money.
