Long story short, I got a i7-4790k coming in and I wish to know how does overclocking it work since i hear it is very different from the time i overclock my 2500k from in 2011. From what I understand 4790k have a base clock of 4.0ghz and when it go turbo mode it go to 4.2-4.4. I find it a little confusing since for my 2500k I just set mt stepping to 44 and it go 4.4 ghz all the time.

You can do the same thing, have it set to 4.4 all the time. the i5 2500k had a turbo as well, you just bypassed it by setting the core @ 44x100 (4.4Ghz)

So for like example i set it to 4.5 and it will be at 4.5 and no turbo mode like 2500k? And second, think Corsair A70 is up to the task for it?

Most 4790Ks can get up much higher than that with a slight voltage tweak. Most chips can hit 4.8 GHz with 1.3V or less. I have one on another rig that's running 4.8 GHz @ 1.18V which I believe makes it a golden sample of some kind. 4.8 GHz seems to be the wall for most of these chips and requires significantly more voltage to go higher. I had to increase it to 1.3V to hit 5GHz.

The only difference between 2500k and 4790k is the unicore a.k.a cache speed.

I have core set to 4800mhz, vcore 1.325v @ adaptive, offset +0.001v, unicore = 4300mhz, vcore = 1.2v @ adaptive, offset + 0.001v.

My 4970k under water runs 4.7Ghz solid.

Yep, same principle, just different numbers. You won't be getting a 1+ Ghz overclock on these, but I am very satisfied with the stock speed performance.

yeah, even stock turbo of 4.4 is nearly enough for all games
