Well it's the top end Z77 chipset so has all the overclocking features of both Sandy Bridge and Ivy Bridge, and a mid to low end board with a 4+2 phase power design so I reckon a safe 4.5GHz OC with a decent cooler (Freezer i30 (decent) or if you want to spend a little more, Noctua NH-D14 (the top end of air cooling)).
I have used the previous generation P8Z68-V LX (with the same specs, bar the Z68 chipset) in a 2500K build, so I can't really see the worth of spending the extra on the new board if you're buying a last generation chip.
I've already bought the board (got it at a nice price), aha, thank you!
How would a Hyper 212 Evo perform, I've read quite a few reviews that say it outcools the NH-D14 even though it's cheaper
It performs extremely well for the price, but I wouldn't say it beats the Noctua. Enough for a 4.5GHz OC though. For the OC, just do it with a multiplier increase and a voltage boost, I wouldn't suggest the built in overclocking utility.
Thanks! One last question, what would you say the most stable OC (if any is) as I want to be using this processor for around 3years hopefully (unless computing gets VERY cheap and a LOT more powerful) aha
So yeah, longevity C'dGHz, what're the lifespans like?
As long as you keep voltages within reason and temps down (below ~60C max at load) then it shouldn't make much of a difference at all. The chip will, ruling out other problems, run for much longer than 3 years, even at that kind of OC. I wouldn't push it much higher though.
Do you plan on leaving this on 24/7 or standard computer use?
I don't know how the BIOS is on the Z77 P8Z77-V LX's/LE's, but on the P8Z68-V LX/LE, you can only adjust Vcore with offsets. I would hope that they changed that on the Z77 LX/LE versions, but if not, I can say from my own experience with the P8Z68-V LE that it makes it a little more difficult to OC with, since you don't know the exact voltage you're giving it until you get into Windows.
Anyway, I have to use a +.025 offset (1.328-1.336V because it fluctuates) to be stable at 4.5 (my current every day OC). You're right though, that 4.5 with a 2500K is pretty much the standard every day OC. Also, I OC with the main multi, not Turbo multi's, myself.
The only problems I envision with that board is the 4+2 Power Phase design. Less stable voltages mean less stable OC's as you go higher.
The build atm is still waiting delivery for the ram/hdd and optical drive (it's annoying)... But I will be using intel's integrated graphics for the time being, until June 1st (money day!) then I will be using a 6870 most probably
