I love overclocking. I've been doing it for years (since my AMD XP 2400+ Tbred).
I am running my Core2Quad Q6600 @ 3.4Ghz (stock is 2.4) with air cooling. I could go higher with water cooling, much higher, but that's not really worth it for me. What was worth it was my
huge heatsink . I recommend getting a non-stock heatsink, as most are pretty lame. You can probably get that up to 2.8Ghz without much problem, and even 3GHz if you try really hard.
Anyways, if you want to know the gritty details, I can help. Just not now. Look around on The Google for a bit. Most overclocking is done in Bios. Increasing the Core Voltage, the Bus Speed and the Multiplier. There is a lot more to it, obviously, and there is a ton of stuff on the web about it. Hell, someone probably has your exact computer and has overclocked.
Downsides: 1) Overclocking shortens the lifespan of your cpu.
2) Runs the risk of frying your cpu!
3) Uses more electricity (for those of us who pay that stuff)
Upsides: 1) 1337
2) More performance per dollar!
3) Gives you the extra juice you need, if you need it (and you do)
4) is fun as hell.
Main thing is you need patience. It took me forever to get to where I am. I went about 5MHz at a time (which is a little over-careful, but hey, I just got this cpu!).
Research research research. You can never do enough research. And by that I mean look at what other people have done right and what they have done wrong.
be back later!
