first attempt at oc'ing 3570 at 4.2ghz. can go higher i think!

Hey guys currently overclocking my 3570 and z77x-d3h I have left everything to auto as i'm very new to all this overclocking business

the only settings i changed in the bios were disabling onboard graphics, turbo power limit to 250, core current limit to 250, CPU PPL voltage to 1.65 and then changed the turbo mode multiplier to 42 on each of the cores. I left all power saving options on. how does it look?

Is there anything I could improve on i would really like to get to 4.4-4.5ghz but when I tried 4.4 i was hitting temps of 85-88c on the autovoltage that the motherboard set!

voltage looks high, try reducing it manually a bit or keep it the same and up your ratio and see if its stable.

once you hit stable you should try to drop the Vcore if you can to keep your temps down.

a better cooler will drop temps and give you more headroom of course

how can i up the voltage though but still allow it to be flexible so when im not gaming or doing cpu intensive tasks it drops down to the 1.6ghz low usage mode and when i game gives it the extra volts and multiplier to take it into the 4ghz zone.

Just leave Speedstep on, and use a negative offset (to allow volts to drop when at low speeds)

dannykebab · 14 Jun 2012 at 23:40

ah ok ill try it out, so leave speedstep on and disable what else, by the where can i find negative offset on the z77x-d3h cant see it anywhere!

I'm not familiar with that motherboard, but you should be running on auto offset at the moment (check to see that your Vcore drops at idle). Look in your instructions on where to find voltage settings to configure the offset setting, and then use a negative offset, which will basically minus the chosen voltage from whatever the motherboard would have automatically delivered. At the moment, the motherboard is overestimating the voltage needed (most do this), so you could try a negative offset of around 0.05v, to bring your load voltage down to 1.16v. Check to make sure it is stable, and then you could try a larger negative offset to bring it down a bit more. Conversely, if it is not stable, then use a smaller negative offset to bring the voltage back up. If you aren't already, use some LLC to help reduce voltage dips under max load, I use 50%- some cheaper motherboards don't handle LLC very well, and end up with large voltage spikes when you go from max load to idle, so I only use 50% just to be on the safe side, but it still helps to keep it stable with a lower Vcore.

I've got the same setup, when you go into the voltage menu, the top one is the Vcore, it's the one underneath that. You need to change Vcore to 'manual' I think it is, then you can change the one underneath it, might take some time as you need to go from -0.625 or whatever it is down to -0.050 or similar.

dannykebab · 15 Jun 2012 at 10:34

Right but if I change it to manual wont it always be locked at that voltage, negating the power saving option where the cpu gets given more voltage as it needs it and less if it does not?

Pulse · 15 Jun 2012 at 11:09

Change until you set the Vcore to 'normal' not 'manual' then you should be able to change the offset underneath. I can't get it stable using offset (but I don't really understand how offset works atm) so I leave mine at fixed and I don't have any problems with it.

dannykebab · 15 Jun 2012 at 12:33

ok will have another try after I've reseatted my cpu cooler as my temps are a bit hot at the moment i think. also I am using a friends ram at the moment so dont want to push things to hard incase I damage any of his stuff, will have a really good go at 4.5ghz when my samsung ram arrives from oc :cool:

Gav_881 · 15 Jun 2012 at 12:42

I think the offset is a range value rather than a set value it should work similar to cpu fan control Ie when its hot the fan goes faster and in turn when the CPU is being lazy it feeds less volts.

I could be wrong here though so i'd wait for someone to shout me down or +1 before you take it as red

dannykebab · 15 Jun 2012 at 21:24

how does this look guys

4.4 left all power saving options on and changed voltage to 1.250 in bios with load line calibration set to turbo and a cpu pll of 1.65,

cores 1,3,4 average 66 degress under 100% load in prime and core 2 averages 70 degrees

That's not bad actually, I'd be happy if my chip could do 4.4Ghz, an extra GHz would be nice. I managed to get it to boot with 4.3 but that was at 1.27 to begin with and then I started to drop the voltage down, think it got to 1.24 before I gave up and went back to 4.2 at 1.19v

dannykebab · 15 Jun 2012 at 22:07

thanks man thats good to hear because the last two overclock builds i have done... ive had terrible luck with bad chips first it was my amd 64 3200+ and after that my core 2 duo e6300 which only hit 2.8 :/ I think i could get it to 4.5-4.6 easy with the right cooling. but for now i'm happy with 4.4. what temps do you get at 4.3?

Pulse · 15 Jun 2012 at 23:53

4.3GHz at 1.24v temps were 75oc thats with Intel burn test. Only about 65oc in prime. If you're hitting 73oc I'd run Intel burn test because that'll add another 10oc, run it on high for best stability tests. Now at 4.2GHz 1.19v ITB only maxes at 67oc, prime only 54oc.
