Cant be more thankful to the person who setup this thread. I just got my 3570k just a couple days ago along with the ASrock Z77 Extreme 4 motherboard from MicroCenter, bought them as a combo and got an awesome deal - Anyhow lets get back on topic.

This guide helped me clock my 3570k on the 2nd try to 4.3ghz, I am not willing to stop there. its just that i went from knowing little about the ivy environment to understanding all the crucial information about ivy and it just took me very little time to get my system stable and in good shape.

I know 4.3ghz isnt a big overclock and that I am willing to overclock further but I am being held down by college classes and will get back to it soon smile.gif

again.. thanks so much for setting up this thread, very very helpful. i will advise it to others who will be in need of help in overclocking their Sandy/Ivy bridge.

good job thumb.gif

You're welcome! upsidedwnsmiley.gif

Please don't forget that Ivy Bridge is on average 5% (more or less) faster than Sandy Bridge. So an Ivy Bridge clock of 4.3GHz is equal to about 4.5GHz on Sandy Bridge! thumb.gif


Soon to come feature of this guide: CPU LLC steps to choose the best setting!

Edit: Added the above comment as a note in the top of the guide. I think it's an important fact many people might over look.

Excellent guide.. Is there a guide like this for Asus motherboards? I did a quick search but didn't see anything.

4.5GHz seems to be the sweet spot for most 3570Ks.
For most people, 4.5GHz only requires a slight boost in voltage, while 4.6GHz requires a lot of people to jump from 1.20-1.24 to 1.29-1.30, and 4.7GHz is usually around 1.35v.

Anything lower and you are challenging Intel themselves.

My i5 3570k is getting extremely hot around 85-90° when overclocking to 4.3Ghz with a basic +0.005 offset and +0.004 turbo which gives me a 1.240v on load. Yesterday I tried experimenting with undervolting and I've gotten the same core clock stable with a -0.200 offset and +0.120 turbo at 1.176v on load with temperatures around 75-80°. When idle the core voltage is around 0.816v and it passed a 12h Prime95 blend test.

Now I was wondering if there are any downsides to undervolting since I couldn't find anything about it in the guide. Are there any specific reason/risks why you don't like it? I couldn't find any minimum recommended voltages on the intel website so I assume it's okay.

Although in the guide I don't support it, it doesn't meant you can't do it.

As a general rule, I don't recommend it to avoid many users getting idle BSOD from having the negative offset send the idle voltages too far below. But some people will find that they actually can and want to use a negative offset that gives them no idle BSOD. That is OK with me.

It's your setup. If it works, it works.

Ok, here we go,

Had to fiddle with the vcore a tad, it shoots up a little high with AVX higher laod and E3G3's implementation of LLC.

However, itll go back the way it was because I for one think AVX is a little unrealistic right now.

Little surprised we keep EIST and Turbo on now. Has it been that long since I had an intel CPU? headscratch.gif

Imagine how life will be like 50 years from now. A bit scary. More so intriguing. Can't wait! Hopefully I make it that long. smile.gif
