Have people never heard of google?

Maybe he should Google that.

seriously mate, this is a forum for Windows 7. How does anything in your post relate specifically?

Ok, i'm sorry. I exagerated.
But still , i can't find an i7 OC Tutorial.

To make up for my mistake i myself answered some questions:

Crysis only Recognizes 1GB: Myth
4870x2 overclocking: Yes, but not much since the card runs hot.
4870x2 crossfire: Yes you can, until how many PCI Slots-free you have i think.
4870 and 4870x2 crossfire: No, you can't.
RAM OC: Yes, you can, but watch out for Temps.
Failsafe OC: Don't Know.
Differences between Core i7 to Quad: Difference between Quad/i7
GTX295 vs 4870x2: GTX 295 Wins not by much.
Is it cost Efficient: Depends on your budget.
You can't SLI with different Models like GTX GT GS.

I heard that it is possible to overclock it to 4.5 GHz. How do i do it? Like a Step-By-Step tutorial

Number 1 rule: every chip is different. Some overclock great, others not at all. Also, your options depend completely on your motherboard. In general, you raise Front Side Bus speeds, you raise multipliers and you increase voltage. Then you add cooling and test for stability. There is no step-by-step guide I'm afraid...you have a lot of reading to do.

I recently built a new machine with a Q9550 cpu and a gigabyte mobo. I'd estimate I spent a solid 15-20 hours reading online on how to overclock with my equipment and get the best results. My goal was to stay on stock cooling. I took it from 2.83ghz to 3.2ghz and it's completely stable and quite cool. But the key point is that it took a lot of reading and learning.

What are the differences between Core i7 and Core Quad?
Because when i saw on my friends computer, there were actually 8 cores being recognized on Device Manager and everywhere. Many people say that it is still a Quad - Core.

The core i7 is newer and faster. I'd check Intel site for exact details.

With regards to number of cores...the core i7 is still a quad core. It just has hyperthreading again...so Windows see's it as 8 cores....but it's really 4.

What is the Melting Point of a CPU and a Video Card?

Everyone is different.

And he also bought a Core i7 920 Model. How do i overclock it to 4.5 GHz or 4 GHZ?

That's a huge overclock there...almost 2x. Again, no tried and true guide...every CPU and motherboard is different. You will be tinkering with a ton and most likely having to resort to watercooling to pull off that large of an overclock.

Thanks for answering those questions, and yes i will have a water-cooled PC so i think i will be able to overclok it to like 4.5 GHz.
So basically, for the Core i7, Windows recognizes wrong numbers of cores right?

Thanks again,
Alex.
