You should expect to need about +0.06 V going up 0.1 GHz. So if you know 1.20 V was the lowest possible at 4.3 GHz, you might want to try somewhere around 1.26 V for 4.4 GHz.

Just keep upping the voltage and watch temps

Awesome thanks for the post link, good thread write up you made. So the stock volts for the i7 3770k are 1.070v like you had posted up, Thati s good to know. I'm gonna try a few things and see if I can slowly bump up the speeds from stock speeds. Instead of jumping into says 4.4ghz without testing other numbers first.

Very Helpful man, thanks a ton!. I will definitely keep that into consideration when amping it up every 0.1ghz and testing it out to see if its stable at the same voltage or needs more juice.

Yup, that's what I plan on doing now. Instead of jumping directly up to say 4.4ghz or more I'm going back to stock speeds and volts and going up slowy from there. So far now I put it back to stock voltage @ 1.070v and bumped it up to 4.0ghz, 0.1ghz higher then stock and so far its running stable at stock voltage @ 4.0ghz. So I plan on going 4.1ghz next and upping the voltage when needed.

Another question on this subject though. In order to do any form of overclocking with the asrock extreme6 and i7 3770k, do I need to mess with the Voltage Offset and Turbo Voltage at all or can I just up the All Cores speed and ramp up the voltage as needed? Just want to make sure theres nothing else simple I am missing.

That turbo voltage setting is something that people often won't know. I didn't see it on Gigabyte, only saw it with ASRock. That means you have to be careful when talking to people. There could be miscommunication about offset and turbo voltage.

Generally, people are interested in that offset stuff because it's needed if you want the voltage to go down when the CPU is idle. Voltage normally drops to something like 0.8 or 0.9 V at idle. If you use fixed voltage, it won't go down.

The offset voltage is something that gets added to the stock voltage. Your CPU has its own unique "VID" voltage it demands. It's set by Intel in the factory after testing each CPU by itself or something. If you don't use fixed voltage, "Vcore" is the result of "VID + Offset". Offset will increase (or decrease) everything, including the idle voltage. Idle voltage will still go down, but it will be higher than at stock.

Offset is a flat value. That means if you used fixed voltage until now, you can deduce your offset voltage if you know your CPU's VID. I know my CPU has VID 1.18, and I know it is stable with my overclock at 1.255 V. This means instead of fixed 1.255, I can use offset +0.075.

ASRock has that turbo voltage stuff. The dude that wrote the ASRock overclocking guide for Ivy Bridge suggests you keep the normal multiplier at stock (35 ?), then set the four turbo multipliers to 45 or whatever you want to overclock to. You then go and increase the turbo voltage, don't touch the offset voltage. You leave offset voltage at the lowest positive value that is available.

I have no idea how the turbo voltage setting actually works, if it's the same formula as for offset voltage but only for when turbo is on, or if it's something more complicated. I can't say anything about how to translate it to fixed voltage. It definitely sounds like a better setting to use than offset, as it won't increase the voltage if the CPU gets downclocked at idle.

Awesome reply man, thanks. I'll do my best to try and search around for something about it all just getting a lot of different ways to do it all at once so I'm trying to just find the safest and simplest solution to it. Thanks
