1)Downclock to a lower speed on your processor, memory, and/or FSB
2)Increase the voltage to parts of you motherboard, memory or CPU to see if you can get it to work at those speeds.
If you choose option 2, then you are on the track to more speed, but also more heat. Heat is one of the BIGGEST reasons why people cannot overclock to uber high speeds. But, there is also another problem, too much voltage. Although you can increase the voltage on a 45nm chip (Codename: Yorksfield (Core 2 Quad 45nm) and Wolfdale (Core 2 Duo 45nm) CPU) to 1.6v (Yes, you can do this, Intel just says you cannot go above 1.3625v since the chips were not designed for it and/or they do not want you to overclock anymore than that), but the heat produced is crazy at anything above 1.45v on a 45nm chip.
I only have experience with 45nm chips so I will try to add my 2 cent for 65nm chips. Feel free to correct me and I will fix it.
Now, lets get back onto task. If your system does not post or you get BSOD of death or freezing, your system is unstable and needs some more tweaking, which usually is just a little bit more voltage. You need to do so in steps as to find out what needs to be done.
1.Start by increasing the voltage to your CPU by one notch, then save and reboot your machine and if that solves anything. If not, go and increase the voltage by one notch and try again. Do this until you reach 1.3625v on your (or maybe 1.4v on a 65nm chip?). If that still doesn't solve anything then you need to go to step 2.
2.If step one doesn't work, then go and increase your North Bridge voltage (check with your motherboard's manual for what it would be called) by one notch, save then reboot and check again. If not, repeat like in step one till you hit about 1.3v (again I only have experience with the P45 chipset so feel free to correct me or give me info on the other chipsets like the P35 and whatnot). If there is still a problem, then go to step 3.
3.Next try and increase the voltage to your RAM if your RAM is above its rated speed. Do this till you get to about 0.1v above your RAM's rated voltage. If not, go to step 4.
4.Try to increase the FSB Termination (again, check your motherboard's manual if you do not know what it is called on your motherboard) by a notch till you get to about 1.3v. DO NOT GO ABOVE 1.34v (at least on a P45 chipset and the 45nm chips, not sure what the others are like).
5.If the others have not worked yet or you still having some stability issues, increase your PLL by one notch and ONLY one notch. Just raising it on notch took my e7300 from 65C at 3.8 to 71C! Use at your own risk.
6.Now, if you are still having issues (and lets hop not), increase your CPU's voltage by a singe notch till you get to 1.45v. DO NOT GO ABOVE THIS ON AIR COOLING EVER! Heat will just be insane, so be careful.
7.Finally, if you are still having issues, then I have bad news for you. You are going to have to reduce your overclock because it is too dangerous to proceed unless you have balls of steel or have the experience to do so.
If you managed to get your CPU stable after all of that, then start trying to decrease on of the voltages by one notch until you become unstable or you hit your stock (default) voltages. Do this all the way down the line till you are right on the edge of your voltages. This will increase the life span of you parts and also decrease the heat prod
