Safe 3570K OC's?

[ASow123]

Got a factory 3570k with a big ass Hyper 212+ sitting on top of it.
What are some safe overclocks for the 3570k? I'm looking to hit at least 4ghz, my case has about four fans in it and average temp is in the 31c's and I haven't tested it under load yet.

ASUS Extreme4 Z77
i5-3570k
8gb DDR3 Ripjaws
700w PSU
Sapphire Radeon 7850 (not in yet)

Also is that a good temp for my computer to be idling at?

You'll be able to get to 4Ghz just fine, and yes, 31C is just fine for idle, as well. I'd say you should be able to get to 4.2-4.3 without much issue and possibly 4.5, if you're willing to run it warm.

Should I be messing with the voltage or?

For 4Ghz you might even be able to undervolt it a tad actually, but just see how far you can go on stock voltage and still stay in a safe temp range.

What's the price of undervolting/overvolting?

 

[ASow123]

As in what can happen?
I have a 700w PSU that's probably not even using half of that to run my rig, does that affect your opinion on undervolting it?

 

[DJDeCiBeL]

Undervolting is a GOOD thing if you can do it because it'll run cooler (always a good thing for Ivy CPU's). No harm in it at all, other than instability, but that's not actually damaging.

Overvolting causes MORE heat and slightly shortens the life of the CPU, increasing more the more voltage you use, but from what I've seen, that won't really be a problem anyway, since Ivy CPU's don't really like adding more voltage because they get too warm.

So, as I said, just try undervolting or see what you can do at stock voltage.

Thank for your help DJ!

No problem!

How would you go about testing for stability?

I'm glad I found this thread because I'm about to purchase an -5-3570K with an ASRock z77 Extreme4 cooled under a 212 Evo. I have no plans overclocking it over 4.5 GHz.

How would you go about testing for stability?

The two main programs used for stability testing are Prime 95 and Intel Burn Test.
