Help overclocking i7-4770K on a VII Hero?

toon_mad · 8 Jun 2014 at 19:10

Hi, just done a new build (which is in my sig).

I have limited experience on overclocking Intel as it has been years, I can usually get some decent overclocks on AMD builds but typically following guides etc.

Anyway I have had a quick look in my BIOS and the options are unbelievable, an overclockers dream I would imagine

Does anyone have a similar setup or guide to help me along the way? I am looking to reach a stable overclock hopefully of anything between 4ghz-4.5ghz.

Here are some screenshots from CPU-Z if they help:

Thanks

Hi Toon, as no-one else has replied, I'll chip in...

I assume you have a half-decent cooler. I wouldn't recommend doing much with the Intel stock cooler... EDIT derp. Read your sig...!

Try this lot for a start:

vcore 1.22v
ring/cache voltage 1.175v
System Agent (SA) voltage +0.200v offset
turbo multiplier to 45
LLC to extreme
PWM phase control to extreme.
XMP enabled.

Leave everything else on auto for now. If it boots, try an hour or two's general usage to test stability. If it BSs or locks, tickle the vcore up to 1.23v and try again.
Hopefully, 1.22 will be plenty- 1.20v may even do the trick.

If you have any problems, try a 42 multi with 1.20v vcore- this should be in range for even a slightly ropey chip. Have my fingers crossed you got a decent one!

Or the other way of doing it- just chuck the multi straight to 45, leave vcore on auto and see what the mobo thinks it needs. You can then chip it down a bit. Max for air cooling is about 1.25-1.26v, but as you have water, 1.3v ish is doable if necessary. I'd imagine you wouldn't need this much...
The other settings I mention should still be changed- my personal experience is that they help with stability (I had very limited success until I upped cache volts and SA volts).

took 1.32v to be ibt stable. temperatures seem to be good though, 68-74. i just set the multi to 45 then manually increased offset volts.

Will be interesting to see your results.

Hi mate, I actually had set the multiplier to 42 and vcore to 1.2v to get 4.2Ghz and it seemed stable using RealBech, idle temps are between 28c-33c as the thermal paste still has not settled.

I might try as you said and set the 45 multiplier and leave voltages on auto and see what it needs.

So leave the vcore on auto and just change the offsets? Not sure what to change it to if i am honest, but im gonna try what dougal1331 said and leave voltages on auto and set multiplier to 45.

Setting the multiplier to 45 and leaving on auto is unstable, tried setting the vcore to 1.3v and also unstable.

Will now try the first method you posted dougal

Update your bios to the latest and you will find some preset overclocks you could try

I just over clocked mine to 4ghz and left it there as it would seem I lost the i7 lotto. (VII Gene)

Bios is updated but I cannot even find the preset overclocks

I think I will just leave it as is on 4.2ghz with 1.2v.

I couldn't even keep mine stable on stock settings lol. Not used to the crazy bios either, first time away from amd for me.

toon_mad · 11 Jun 2014 at 12:28

The bios is for the absolute tech heads because I certainly dont understand half of whats in there and I have not even properly scratched beneath the surface!

One day I might feel like living dangerous and dig deeper but right now I feel safe not going in there

Also have you not tried manually setting the vcore yourself and see if you can hit a little higher?

McstylisT · 11 Jun 2014 at 12:43

From the sort of volts needed maybe 4.4ghz would be more achievable. ?

You would need at least 1.85v VCCIN volts
probably 1.28v-1.3v main CPU
Ring volts would be 1.11-1.19v

Leave the rest on auto see how you get on there. But TBH 4.2ghz is very snappy and is very minimal difference from daily use.

I could, but I'm using 350d case with a 280x in there, Gets a little warm lol. I went into it wanting 4ghz. Was actually going to go with an i5 but a i7 came up sealed for not a lot more ££.

Ok I will try these thanks, I just like to get a higher overclock even if the difference is minimal, 4.4Ghz sounds better then 4.2Ghz, just as 4.5Ghz would sound way better then 3.5Ghz

Yeah I know what you mean, my motherboard temps are quite high also so thinking of putting either more or better fans in there.

Also as I posted above, and like McstylisT said I think the difference in overclock is going to be not so much noticeable. But at the same time I want to squeeze as much as I can

Apologies for hijacking this thread, but I've tried DoneADougalOnSofa's settings on a VI Hero and even with CPU voltage up to 1.35v I can't get it stable @4.5ghz. Just a bad chip? I've delidded and currently running [email protected], Prime stable with temps ~68C on the hottest core (K2 cooler). Any ideas?
