Overclocking question on the E7400?

Okay...this can't be completely and thoroughly answered through one small post, but I'll do my best to give you a crash course. First of all, do only one thing at a time. My advice is to leave the GPU bus speed alone until you get the hang of overclocking the CPU first. First, unlink the memory. You also need to manually set the timing and voltage for the OCZ ram. I use that ram a lot and it can handle a lot, but you have to set it correctly. Set the ram up to stock specs, something like 5-5-5-18 and give it 2.1 volts. That should make it stable. On the CPU, you also need to manually set the voltage. Start with 1.25. Push the fsb 10mhz up at a time and restart the computer all the way into windows. Run CPU-Z to check your overclock. If it's stable, restart the computer and push it up another 10mhz. Keep doing this until it will not restart. At that point, go back and bump the voltage up another .05 and repeat the process. You need to be very careful with this. If you have a stock heatsink/fan, I wouldn't give it more than 1.35 volts. The extra voltage helps stabilize the overclock, but will generate lots of heat. You need to invest in a good heatsink/fan combo to get the most from your processor. Once you max out your CPU and feel comfortable, you can start playing with your ram. On the ram, go up 25mhz at a time and you can relax the timings a bit if you want to go higher. You can also push the Reaper Ram to about 2.4 volts, although I would try to keep it at 2.2 volts or less. You can get 950mhz at 2.1 volts safely with timings of 5-6-5-18 or thereabouts. The ram gets really hot and performance will start decreasing as you push it harder. You can also check it's status using the CPU-Z software. PM me if you need more help.
