Help me get to 4.5GHz

post #1 of 6
Thread Starter 
Just got a new 3570K and Gigabyte Z77-UD3H mobo. Currently running it at 4.2 with stock voltage. I was Messing around with it and I could only get 4.5 stable at 1.37 voltage. I used http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end/830#post_18557022 as a guide when doing it, But I see most people being able to run alot lower voltage. At this voltage one of my cores was hitting 82* on prime 95 and I am not very confortable with that. Any help would be greatly appreciated.

Hi, although most people will be able to hit 4.5GHz at a low voltage not everyone will. For there to be good overclockers there has to be bad overclockers. You might just got one that was not a good overclocker.

You can try playing with some of the other voltages instead or the the FSB.

One thing to keep in mind is this. Although most people will get to 4.5GHz it is less than a 10% increase in speed over 4.2GHz therefore it is not worth more than 5 degrees or so to go from 4.2GHz to 4.5GHz. Anyways clock for clock the 3rd gen is faster than the 2nd gen so you are doing pretty good. I only got my CPU to 4.4GHz on stock voltage (2500K) I had to get it to 1.34 to go to 4.7GHz so it just wasn't worth it to me even though the temps where still fine (water cooled). A small gain in performance is just not worth a large gain in temp to me.

This might be common knowledge, but i just shaved 12c off my CPU.

The CPU PLL voltage was set to 1.85v in the BIOS (Auto/Stock). I dropped it back to 1.60v and saved quite a lot of heat thumb.gif
