i5 3570k to 4.0Ghz?

post #1 of 8
Thread Starter 
Hi OCN,

A friend of mine is looking to build a rig with an i5 3570k, an AsRock Z77 Extreme6, G.Skill Ripjaws 1600Mhz (9-9-9-24) in a CoolerMaster HAX 912. He's looking to overclock to 4.0Ghz stable which I think is possible on stock (I don't have much experience overclocking any of the newer i5s so of course I could be completely off). He on the other hand isn't sure about it. Do you think an aftermarket cooler is needed or even just another fan, say a Noctua?

Thanks,
Jaidyn

You should get 4GHz even with undervolting. For example i have 4GHz at 1.112v. Aftermarket cooler is only for noise reduction purpose. If he wants to go higher then the cooler will be necesarry as ivy gets freaking hot very fast.

Here is my table with multiplier and required voltage:
(but ofc. each cpu is different, and i consider mine an average)

always take info on volts with a grain of salt as not all chips are the same.

my 3770K is @ 4.5Ghz on 1.20V

So it seems like 4Ghz is easy on stock. Thanks all. smile.gif

4ghz doesn't even need a voltage increase. so yes your stock cooler should be able to handle it, if not then you can easily buy a cooler anytime.

Yes, but there really isn't such a thing as stock voltage, since every motherboard gives different voltage when you leave it on auto. For example, when I overclocked my 3770k to 4ghz and left the voltage on auto, it was pumping up to 1.288v, which is a lot of voltage for 4ghz. In fact 1.288v can give me 4.5ghz stable. I can get away with 1.050v for 4ghz stable. Some chips can get away with lower voltage.

thats the problem with leaving vcore on auto, it tends to push more volts than needed as you pointed out in your experiences. i think the OP was refering to the stock cooler tho.
