How far could I O/C the 3570K

Just so you know I haven't actually built this yet but I am just wondering how far I could overclcok with this build and what voltages and stuff to go to. (This is my first build and am not familiar with overclocking)

i5 3570k
Hyper 212 Evo
MSI Z77A-G45
I'm not sure about the thermal paste should I use the one that comes with the EVO or buy something else?

Thankyou.

Different for everyone. But with that motherboard, I wouldn't go past 4.2. My MSI G43 motherboard just reset my OC settings to stock and now won't change them.

cough- I have that board and I keep mine at 4.5 and never had any mobo Issues and i safely taken it to 5.0 with a 12 hour prime test with no issues but I don't need it that high for anything I do.

Running my i5-3570k @ 4.5Ghz 24/7 on a ASROCK PRO3 board.

Forgive me if I'm wrong but don't you have to change the voltage to overclock? Again I may be wrong since I am new to building. What voltage to you have yours set to?

Depends heavily on the chip. Each chip is different and just because one guy can hold 4.5Ghz doesn't mean the next guy will with the same equipment. However, here's how it works in a very basic point of view.

You boost the clock (with multiplier settings on a K-Series) and get a higher frequency. At a certain point the voltage (only if not set to auto) will need to be increased to preserve stability as the higher the clock the higher the possibility of instability.

Now the worst part, higher voltages can cause more degradation of the CPU itself along with heat it can severely lower the overall lifespan of the CPU. However most low overvolts won't effect it's usable lifespan as by the time it fails you would have upgraded a couple of times. However, this can actually be completely the opposite as some chips react different to voltage. I've heard of guys frying their Ivy Bridge chips at as little as 1.375v for only a couple weeks. While I've also heard of guys running 24/7 for quite a while at even higher. So the risk is in your court with the voltage settings. Personally I don't let my Sandy Bridge go over 1.3v often and if I had an Ivy I'd probably have that limit set to 1.25v or lower.

However out of the average, if you applied the thermal paste correctly, learn about voltage setup, and know how to test for true instability... I'd estimate you could get 4.5Ghz out of that chip with decent temperatures while staying within a decent voltage.

Thankyou for your reply, lots of information. I will try to learn more about overclocking but can I trouble you for a few more questions? How long should I run Prime95 for to see if it is stable? And if it isn't stable what will happen, how will I know? Thankyou again.

I usually run Prime for at least 4 hours and I like to make it through 24. I use IntelBurnTest to make sure I'm not running too hot as well.

Instabilities can be as simple as a worker failing in prime which it will let you know to complete system lockups and blue screens.
