Overclocking my Sempron 2400+ on an Abit KV7
Tip for overclockers. Sorry, it has nothing to do with Linux, but since it’s the first time in my life I manage to get an overclock working, and couldn’t find any complete information googling around, I had figure out the correct way of doing it, so I just want to register it for future reference.
I have an Abit KV7 (thanks Helio Castro for the suggestion) with a Sempron 2400+, 512MB DDR PC3200 (400MHz) and a very huge Volcano 12 cooler. The table bellow shows the general idea about what I did and the results I get:
As you can see, I managed to change my Sempron 2400+ into a 2800+. To make it happen, all I had to do was change the FSB, which makes the processor talks faster with the board and use all my RAM power (200*2=400MHz). But since that would also overclock the PCI bus, in a way my AGP/PCI devices wouldn’t work, I had to change the divisor to 6, so I could get 200/6=33MHz. Also, the VCore needs to go up because the more speed you want, the more power you need.
In the end I had a general increase of 20%. More MHz, more bogomips, and less time compiling (one test program reduced from 26min to 20min), with no changes at all in mobo or cpu temperatures, which proves that a good motherboard and great cooling are the secrets of a nice overclocking.
