1, Shouchang 350W power supply , I do not know if it is not labeled false power? Overclocking is a requirement that the power supply must be power stable.
2, ASUS K8N4-E front-end bus frequency 1000 (MHz) very high front-end bus can ensure the stability of the overclocking. nVIDIA nForce4 chip has also been very mature, your CPU is not the narrative is wrong. 754-pin should be Supermicro Sempron 2500 + 754-pin 64bit is Sempron rather than Speedlane, right? If it's Splendid Dragon, that CPU should be able to be successfully overclocked to 3000+ or 3200+, and please forgive me for not having heard of 64bit that low for Splendid Dragon.
3, overclocking steps, under the BIOS is generally the first row on the right is the overclocking settings, ASUS motherboard I have not used, personally I think that the seven rainbow and ShuoTaiKe's better super. Asus should also be able to. AGP / PCI frequency must be locked, other almost no need to adjust, press PageDown a little jump frequency can be,
One time 20M super, get a time into the system, run a point program, until the most stable until adjusted to the most stable, I think it should be able to jump to 280 or so! Please do not adjust the voltage, personally I think AMD's jump voltage is not very stable, besides, it will lead to high temperature.
4, in the process of overclocking, pay attention to the CPU temperature! Generally in the BIOS left bottom row display, if the CPU standby temperature >= 60 degrees, it is recommended to replace the fan or reduce the frequency.
5, overclocking stability lies in a good motherboard, good cooling fan, power stable power supply, stable performance of the memory, you can not do without.
6, overclocking failure as long as the CMOS battery discharge can be, you can replace the battery next to the jumper 1-2 pins 2-3 pins shorted after the jump back on it, or directly pull the battery. Remember to take your time with overclocking, it's not worth it if you burn the CPU.
Said tired, the detailed process can not say, if you want to explore, add my QQ12045698
