A guide for overclocking

Don't know if you've already seen that page but it contains two very important pieces of information; the Thermal Specification and the VID Voltage Range.
Thermal Specification is basically the maximum temperature your CPU is designed to operate at. It will and can however heat up more (to somewhere around 95 degrees) before it shuts your computer off to prevent damage to itself. The first you want to make sure is that you are NOT transgressing the thermal spec limit when stress-testing after an overclock. As a general rule of thumb, your CPU should stay around or under 60 degrees during a stress-test (like OCCT or Prime95).
The VID Voltage Range is the max recommended operating voltage recommended by Intel. 45nm CPUs are a lot more sensitive to voltage than 65nm CPUs. Either way, it is a REALLY good idea to keep your voltage UNDER 1.3625v (if you have a 45nm CPU, which you do) if you want your CPU to last for a long time. If you obey the thermal spec and voltage range limits, your CPU will be safe and fine.

OC'ing using the NV Control Panel is not any safer than upping the FSB using your BIOS. NVCP is doing the exact same thing, except it is more likely to crash.

A good way to OC in your bios is to up the FSB and leave the voltage on AUTO. That's basically a guarantee that your system won't hang or not-POST. However, the mobo always overestimates the voltage needed when it's on auto so there is always room for decreasing voltage (and your temps).

I'd say head in to the BIOS and up the FSB so that your CPU speed is 2.8Ghz. Leave the voltage on AUTO and see what happens. If you don't POST and have to reset the CMOS then there is something seriously messed up with something in your system. Anyways if you get to 2.8 try 2.85, then 2.9. Check your voltage and temps along the way. Since you're on a stock cooler I'd recommend staying fairly close to stock volts. When you get your new cooler then you can go for higher volts and higher clocks.

One last thing to keep in mind: Heat increases linearly with FSB increase but it increases with the square of voltage.

EDIT: This has got to be the longest post I've written in a long time. I'm sure you'll thank me for it.
EDIT2: Bah, this post isn't even that long.

Thanks for that info! Actually first time I'm Overclocking Processor trough Bios. I would like to know what POST is and also how do I stress test the processor? I understood the rest though thanks.

POST stands for "Power-on self-test." This takes place before the BIOS shows up. My motherboard gives a short beep I everytime boot. That beep signifies that the computer has successfully completed the POST. After that the BIOS shows up. However, what happens when I do not POST (yes, I've done this several times) is that I do not hear a beep, my computer turns on and I'm faced with a black screen and noises of my fans spinning. In which case I have to turn the computer off. My motherboard has a special feature (good ol' ASUS) that returns all changed settings in the BIOS to default after 2 reboots if my computer doesn't POST. Your mobo might not do that, and you might have to take the CMOS out and put it back in.

For stress-testing I recommend OCCT. http://www.ocbase.com/perestroika_en/index.php

There are TONS of good OC'ing guides on the net. I don't recommend going to YouTube to look for one. Get something from good sites like overclock.net and such.

Thanks for the rep, BTW. Glad to help.

Thanks for that too, I'll try it tomorrow since it's a bit late where I live now for me to want to start doing this. XD

Andre Yang, a civil engineer doing his PhD. in the US obtained a high-performing Core 2 Duo E8600 processor, he succeeded in overclocking this chip to a stellar 6.70 GHz clock-speed (FSB 672.16 x 10.0). The processor uses liquid-nitrogen (LN2) cooling and surprisingly this processor was overclocked on a motherboard with the Intel X48 chipset, the ASUS Rampage Extreme when previous record-holders across several recent processors made use of either the Intel P35 or P45-based motherboards. The validation page for this overclock can be reached

That cpu would be god, but I wonder how long it will be till we get to that, maybe never, maybe we wont use cpus, who knows what will be next in computers...

i wish i have a stable 6.70 GHz cpu all my wii games y gc games will be full speed in dolphin loll

Unlikely. The push now is towards parallelism. Meaning that we are going to be seeing more cores rather than increased clock-speed.

AWESOME!
