Overclocking i5 3570k

Hey, I'm kind of confused on overclocking since this is my first time doing it. Currently, I am at 3.9 ghz on the i5 3570k with temps at around 70 degrees Celsius and at about 1.15 V. Is this fine, or should I change settings. I have an asrock z77 extreme4 motherboard and i have a cooler master 212 evo. What is the highest temp range and voltage range I can safely go to? I'm also confused on the offset value for the cpu voltage. I read that applying offset will apply that value +/- the auto value while under load. So, wouldn't you theoretically want to put the offset value at the lowest number possible, that way you can overclock it higher without reaching high voltage? Is there anything else I need to know about overclocking?

Thank you

70C seems kind of high for 3.9 Ghz. I would try reseating the cooler. I've seen people post temps around 60C with that same CPU at speeds of 4.0-4.2 Ghz.

acide24 I am using a cooler that is rated below yours (CM Hyper TX3 92mm) along with the ARCTIC MX-4 thermal paste and my temps max out ~60c doing a P95 stress test. I'm at 4.2Ghz. My absolute stable settings are as follows:
CPU Ratio: All Cores
All Core: 42
CPU voltage: Offset Mode
Offset Voltage: -0.065
CPU LLC: Level 5

Try those and see where you go with it. Play with the offset voltage up or down a little, but it seems that most people with our board are finding that offset voltage as a sweet spot (for 4.2Ghz)

Trust this man ^^ i have the same setup as you and that is what my OC is set to. Works fine and is completely stable.

And yes, you want to use offset mode for this cpu, the lower the -voltage the better. However if you find that your system is crashing when stress testing, you will need to increase the offset voltage.(eg if you had it at -0.065 and it crashed, try -0.055).
If you do this, keep in mind that the lower the -offset voltage, the more volts you will be running threw your cpu and this could shorten its life.
I would personally suggest not to go over 1.200v.

Good luck!

EDIT: oh and btw load temps of 70-80 Celsius is fine. Dont go over 90.

Right now I'm rockin a 4.2ghz OC with 70 celsius load temps, do you think I can make it to 4.5ghz?

Specs:
Gigabyte GA-Z77X-D3H
i5-3570K
Hyper 212 Evo with push/pull SP120's.
Corsair 650D with stock 200mm''s

My room is pretty cool at 20c, right now idle is 29c.

You won't know until you try. Every chip is different.

Try 4.3, then 4.4 and see how that goes.
