Once you follow this forum and others you'll notice many users having wierd or iffy problems. Much of that is due to "power issues" and generally that means the psu/power supply. So, you're 300W psu worrys me. I suggest you get a better and higher wattage unit when you can, sooner the better.
As for OC'ing now on newer systems generally has little to gain until "cooling" is well addressed and even then don't expect much. Newer cpus tend to curtail any massive OC gains and just gernerally the cpu is already at its limits dealing with its own rating. To OC basically deals with cpu setup from the bios setting, tweak away but alittle at a time. Overall, be happy if you get 10% increase. Understand, the whole system has to has quality componets to address the higher cpu OC rate, thus besides cooling, the ram and video need to be of a hi-qulaity as well. You can get good results then after days or months start to degrade and can only achive what your system was build for, so beware.
Hey everyone. I'm new to computers, and would like to try to overclock my computer. It currently has a K8M-800M motherboard, an AMD SEMPRON 3300+ CPU, 512 MB RAM, 300 W power supply, a SOUND BLASTER AUDIGY SE sound card, and an ATI RADEON 9600 PRO video card. Do I need to do anything before I try to overclock, or is this set up fine. Also , how do I overclock the CPU, motherboard, and video cards? Your info is greatly appreciated.
