Hey guys I've overclocked my i7-3770k to 4.2GHz with a voltage of around 1.224V. Is that too high for this kind of an overclock? I'm using an ASRock motherboard, with offset voltage of -0.100. Does this sound right? This is my first time overclocking, any help is greatly appreciated.

 

[junkerde]

no, that's normal. Im running mine now at 4.5ghz 1.28v.

 

[yesitsmario]

Mine needs 1.120v for 4.2ghz

actually thats still pretty high for a 4.2 OC. I'd try to see how much farther down you can bring the voltage. or set to manual voltage and see what it takes for 4.5 Ghz so I can get a better idea of your chip here.

I was going to but isn't -0.1 for offset voltage pretty low already?

I use manual voltage to tell for vcores then I use offset so it might be low of a vcore usage but you might be needing an actually higher voltage to achieve that overclock as the cpu needs more power to regulate when it needs power back from using offset.

so think of it this way. when your cpu idles it is at -.1 vcore offset but at full load its at 1.224 vcore. and when you go from idle to full load sometimes the cpu actually needs more power, unlike where manual you just set it and leave it. it's up to you man.

What do you have set for LLC? If you are using a negative offset it usually helps to use a lower setting of LLC, then you can use a smaller offset (i.e. less negative) which helps keep the idle voltage from dropping too low. So I'd set Medium (or whatever ASRock calls it - maybe Level 3) and then re-do the offset so you still get the same load voltage.

LLC was level 5, i changed it to level 3 and now I am getting a voltage from CPU-Z of 1.176V. It seems stable so far. What do you guys think is a good overclock for this CPU?

What are your full load temps? we need that more than anything really. 1.2 vcore shouldn't be a problem for even pansy coolers

 

[chrisnathan]

Well I now brought it up to 4.4 with -0.07 and the temps are around 65 degrees

whats the actual vcore lol not the offset

 

[enigma7820]

if that is load temps using IBT or Prime95 those are good temps at 4.4 I would say every chip is different keep going until you get to 1.35v and are still under 80c at full load and you will be fine as you won't really see those temps in regular tasks and gaming.

Oh sorry it's 1.216V

run prime 95 for the night and see if you crash. if it's stable that a pretty good chip for that vcore and multi.

My computers not crashing but prime95 did and silver light crashed a few times when I was on Netflix. Does this mean I've got to up the voltage a bit?

Yes this means you aren't stable for some programs so moar vcore is needed.

 

[$ilent]

Is that an asrock extreme4 mobo any chance? These mobos dont report correct cpu vcore so beware that your vcore can be higher than what your seeing in cpuz

I'm only changing the offset voltage, do I have to change additional voltage for the turbo as well?

yes add more total vcore as thats whats necessary as when you run program you aren't idling you are using the cpu. So moar volts. try .02 vcore upage

Surprisingly enough, I can get a stable 4.3 with 1.1V

Must have a good chip
