This is currently the guide I'm using to overclock my new PC to 4.5 ghz, the thing I don't understand about offset mode is this, I understand that we're giving it a +0.005v max offset, but offset from what?? I mean I definetely am stable at +0.005v, but my cpu voltage is at 1.360-1.365, so where are those numbers coming from?

I'm just scratching my head about this particular overclocking method that I'm actually successfully using, and hope someone is kind enough to better explain it to me.

Offset is from 1.3 volts. Set llc to lvl 4 or 5 and you will be right around 1.3 volts under stress.

What's strange to me is that everything appears to give the same voltage in certain ranges, for instance 4.5-4.8 are all reading at 1.365v, then 4.2-4.4 are 1.335v with the offset method, (all my llc's are at 2 I believe, I'll change them now however.) I'd really like an explanation for how it is choosing the voltage.

The harder you load it the more voltage it gives. Meaning if you were at 1ghz it would barely give it any, but if you were at 7ghz it would be giving it tons.

 

At least from what I've seen I believe that's how it works.

Yeah, but according to this guide nvidia, and hopefully you can tell me if I'm reading it right, I set my LLC to 2, then just keep raising my core? That seems dangerous because wouldn't the voltage get too high? I mean right now it is hovering in the 1.365-1.370 range at 4.8 ghz and appears to be stable, I'm scared to go any higher than this.
post #1326 of 9599
Okay, I think I get what is going on now thanks to you nvidia, basically every line level is 30 voltage, so line level 2 is 1.36, line level 3 is 1.33, line level 4 is 1.300 etc. If I can run stable at 1.330v at 4.6 ghz with temps under 65 I think I should be fine for the long term, the processor handles 4.8 with line level 2 like a champ though, I just don't like running at 1.365-1.370

No problem. Glad I could help. :) But as a general rule try to keep the llc as low as possible so the idle voltage will be lower. For example if you wanted 1.3 volts +.010 volt offset would be better than -.02 volts and llc lvl 2 or whatever.

Been awhile since I last posted to this thread. I know the topic has moved on to Ivy, but i have a basic question. I been happily running my 2700K under water at 46x using offset (+70mV - the old fashioned way - no addn turbo volts. cpuz vcore under prime stress =< 1.304V) It can readily go to 48x and even 50x, the later at a cpuZ vore of 1.432 or higher (ouch). Anyway, it's odd that the PC seems snappier and actually quicker/smoother at 46X vs 48 or 50X. Yes - benches are better (eg, AID64, IBT etc) at the higher multiple, but regular usage (net, MP gaming etc) just feels better... Is there really such a thing as a "sweetspot"? or am i just imagining this.smil3dbd4e4c2e742.gif

managed to hit 4.4Ghz. verified thru the tried and true 32hr Prime95 test.

Your VID is 1.3561v which means that is what voltage your chip needs at 3.3GHz so I wouldn't see why you would go less than that unless you can and just want to undervolt your chip.
What cooler do you have?
1.4v should NEVER produce 97C on a sandybridge chip unless your running the stock cooler or a failed install of a custom cooler.

This is my first install and my computer runs 32-35c at idle, do you think that is too high and might be a sign of a failed fan install? Fan is a Cooler Master X6 that does NOT fit inside the case. I bought the thermal paste 6 months ago and it was hard to get out of the tube - is this normal? Also if you think I should change the fan, I have an extra CM 212+ that I can fit in the case, will that affect my OEM Win7 install if I change the fan? Sorry for all the Noob questions, I just want to be in specs before I OC my rig. Thanks
