3570k overclocking - easy?

Curve · 11 Jun 2012 at 23:22

I left it on Auto

Jokester · 11 Jun 2012 at 23:24

That's probably your problem. Can you run CPUZ and see what it says for your Core Voltage when you run Aida?

That's 100% the problem as i once had it on auto and temps were all over the place ! Try setting volts around 1.28 and going lower until unstable . Or like others have mention use CPU z to tell you. But if it was me I'd just set it at 1.28 and work my self down. That's what I did and settled for 1.25.

Curve · 12 Jun 2012 at 00:09

This is CPU-z

And yeah I will go set it to 1.28 and then do tests, and work my way down until its not stable.

Volts look high at 1.38v maybe due to you having voltage on auto?

Yeah, auto mode normally overestimates the voltage necessary, as demonstrated here, because 1.38v is unnecessarily high for 4.5 GHz. If you are using offset voltage (which I would advise to keep idle temps and power consumption lower) then try a negative offset of 0.1 and see if it is stable.

What do I change here:

To do that?

Ty for every ones help, its really refreshing.

Iv managed to pull 4.5ghz just by disabling turbo boost and setting the volts to 1.25! Max load temps at the moment are:

Core1: 58
core 2: 64
core3: 62
Core4: 54

if thats prime stable, then you got lucky. I can't get mine stable at 4.5 without upwards of 1.35 volts

Fire_fly · 12 Jun 2012 at 18:55

I'm currently testing mine with prime at 4.5 with 1.26V. The max temp so far is 77 on core 2. Anything lower and it BSOD before I can get into windows.

Gav_881 · 12 Jun 2012 at 19:43

If you get the V Gene board it has preset OC's to 4.2 4.4 and 4.6 you just select one of them and job done.

You can use it as a base to play and lower your Vcore a bit to reduce temps if your feeling adventurous or just leave it as is, dont forget a nice CPU cooler.

Yup i guess i am lucky

i got it stable on prime 95 at 1.25v and max load temps are now reading :

Core1:59
core2:66
core3:64
core4:60

I'm not familiar with Gigabytes BIOS, but look at how to enable offset voltage, it is normally enabled at default anyway, but if you want to see if you are using it, see if your volts drop when under no load. Fixed voltage will keep volts constant, even if Speedstep reduces the frequency at idle. Offset will allow the motherboard to deliver lower voltage when at idle or low loads, which helps to save power and heat. I would recommend using speedstep (which should be enabled at default), even though many people like to keep their CPU running at max frequency all the time, I don't see the point in wasting power and causing unnecessary amounts of heat at idle.
Enable offset mode if you aren't already using it, and then find out how to set a negative/positive offset from the instructions. Try a negative offset of 0.1v, this will effectively mean that the motherboard will subtract 0.1v from whatever Vcore it would have send automatically- in your case 1.38v at load, which 1.28v should suffice. It will of course also subtract this from your idle Vcore, so you should get slightly better idle temps (though the difference won't be as pronounced as the load temp difference) After that, run a stress test, such as Prime95 for about 6 hours, and check your Vcore, you should see it peaking at 1.28v instead of 1.38v. Hopefully you will be stable, in which case you could increase the negative offset to get even lower Vcore (and thus lower temps). If you aren't stable, then decrease the negative offset in increments, (0.095v, 0.090v etc) which will raise the Vcore from 1.28v in increments. Keep doing this until you are stable.

You want to leave CPU PLL at 1.8V for a start.

Loque · 13 Jun 2012 at 09:09

lowering the CPU PLL helps a bit with temps and I find is a bit more stable.

My chips need 3.9v to get 4.5 crazy!! Anything lower crashes in prime! could it be my cooler? need reseating? whats LLC by the way? i can't see that anywhere on my gigabyte Z77X-UD5H
Think i send mine back if i cant sort it out! 3.9 rockes the temps 90's

Cheers

P.s why does the vots go down. if say i set it to 1.39. it would go down say to 1.34? when running prime hmmm not sure why?

Fire_fly · 15 Jun 2012 at 15:44

The load line setting for the Gigabyte boards is in the power options. 3.9V sounds very high for that chip, maybe try to clock it down a bit, try 4.3Ghz. The voltage drop can be corrected by setting the load line correction to turbo or extreme.

Can't see any power options. can you be abit more specific

I'm still trying to get to grips with this board.
I set the intel turbo tec to auto! and each turbo ratio to 44. is that correct?
But i would like the volts to go down when idle. the only way this seems to happen, is if i set the cpu Vcore to auto?

Any ideas ?

Cheers

Hi guys,

New to all this but wanted to post what I have managed to get so far. Any feedback would be great!

Board: Gigabyte Z77x UD3H.

Currently stable on 4.5 at vcore 1.225.

Max Temps:

Core#0: 57
Core#1: 57
Core#2: 62
Core#3: 59

Still working my way down on the v core to see how low I can go stable.

If I wanted to try and take the chip higher what sort of voltages should I start at?

I can't remember where they are out of hand and I don't have access to my desktop to check for the next few days unfortunately. It should say somewhere in the manual, that is how I found it, or just try all of the sub menus until you get lucky.

All power options are located in: M.I.T -> Advanced Voltage Settings -> 3D Power Control

If you want have the same Vcore in bios and Windows set "Vcore Loadline Calibration" to Extreme.
