Hello. I want to overclock my old AMD Sempron 3000+ 64-bit processor a little bit and I need some help. Its factory speed is 1.81GHz and I tried doing some small overclocking by myself. I raised the FSB frequency from 200 MHz to 210 at first. Everything went fine, no instability, no temperature changes. Then, I raised the speed to 250 MHz and I noticed that my graphics card kept crashing so I finally set it to 235 MHz and it's working fine. Those 300 extra MHz I got are pretty good, but I'd like more.
My CPU is on an Asrock K8NF6G-VSTA motherboard. I have 1GB of DDR333 ram and an Nvidia GeForce 8400 video card. Raising the frequency to 235 MHz decreases the RAM frequency to 303 MHz. (I have set it to do so automatically if it needs to)
There are no problems with the cooling system, in fact, my CPU fan was jammed once and I didn't notice it. With the CPU running at 100% for around 10 minutes, the temperature didn't get above 90 degrees. (I opened SIV Beta then to see my GPU temperature and i noticed that the fan speed was 0). But with the CPU running at 2.12 GHz, the temperature doesn't go above 52 degrees; the maximum temperature i get with its standard frequency is 50 degrees, so i think the cooling system's working pretty fine.
Some extra details: the voltage is set to 1.400V (i can't give it more power) and i also noticed that i can change the CPU multiplier up to x25 (it is currently set to 9). I tried changing this instead of the FSB frequency, but it doesn't do anything, it just hops back to x9. What could be the problem?
So, can anyone tel me how far could i go or what extra modifications should i do? I'm also curious why the graphics card crashes after 250, is it because it's not getting enough power? (I've a 500W power source). Thanks!
