i7 3770k

post #1 of 10
Thread Starter 
whats correct voltage for my i7 3770k @ 4GHz ? It varies from 1.230 to 1.280 (according to Intel Desktop Utilities) average 50 celcius in-game

i used the intel bios to overclock, it has an easy slide bar and did it for me. new to overclock let me know whats up if you get a chance thanks

The correct voltage is whatever is required to keep the chip stable at the desired speed. If you are asking if 1.28V is too much for 4.0, then yes, I would expect much lower voltages at that speed.

I would avoid using any kind of BIOS "easy-overclock" setting or tool, but instead set your own overclock by changing the Turbo Multiplier (and CPU Voltage, if required) by yourself. You should be able to get 4.2~4.4 at 1.25V, dpeending on the chip.

there is no correct voltage. Your voltages are actually fairly low. I wouldnt worry too much. Incorrect voltage is like 1.5v. This is still fairly safe.

Not for what is basically a stock 3770K they aren't.

I thought that said 4.4 sorry I misread. Yeah I would totally lower your voltages.

ya its an intel brand mobo. dz77re-75k
I could use this to tweak the CPU as well. Not sure what to set, though ... ?

If you use that screen, you'd probably want to increase the power limits at the top (so you don't power throttle) and then change the multipliers to whatever you want your overclocked speed to be (I'd say 44 would be a good start). Then you can check for stability using Prime95 or IBT and increase the voltage using the Additional Turbo Voltage setting until you get it stable. For 4.4 you'll probably need something in the 1.25~1.28 range (about what you have now).

You might want to consider resetting the BIOS defaults first, though, if you intend to overclock manually. That way any settings the auto overclock made would get reset. I'd probably also make the changes in the BIOS itself, instead of the tuner software, but it shouldn't make a difference (although it often does).

What CPU cooler do you have? If you are on stock cooling I wouldn't go past 4.2, and watch the temps closely.

I disabled c states in my bios just two of them is that okay? i asrock z77 extreme 4 and set it to turbo 4.4 and its going good!

Which ones? You can disable C3 and C6 (and it sometimes helps to disable them when using offset voltages) but there is really no reason to disable EIST or C1E.
