Z77X-D3H/3570K My personal findings.

So I went ahead and updated my bios to the latest, which fixed the issues I had with my Corsair K60 keyboard not working in the bios, but has had little to no effect on making my overclock any better.

I can get Windows to boot at 4.5 on 1.285v but its not stable, and I very much doubt I will get it stable below 1.315v, so I guess im stuck at 4.4, at least untill I get a better CPU cooler.

yeah, I dont think I got the greatest overclocker ever, but I've gotten it to 4.4, which im happy with. I may get a Corsair H100 in the future, and then try pushing it further.

Oh btw, im pretty sure its 100% stable now at 4.4. Played a couple of hours of Max Payne 3 earlier, and it never missed a beat. Rock solid so far.

Congrats on the OC the H100s seem to be good, although keeping Ivy cool is no easy feat. At these speeds they are more than enough for anything unless you bench or run powerful SLI
 
If you're reading that in the BIOS there's a good chance that with your overclock applied that it's a lot higher, as mine say 1.14V is stock voltage as well, not what the actual voltage is. Something like CPUZ will tell you what the actual voltage is under Auto.
 
hey mate got the same CPU and motherboard as you, personally I left everything to auto as i'm very new to all this overclocking business:P 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!

basically you need to find out what kind of voltages your cpu needs for each bump in multiplier. Mine needed about 0.5v per multiplier increase, but I would consider my cpu not very good for overclocking.
 
Still testing with mine (a couple days on) Had some weird findings, I don't think that I properly understand the offset values as practically whatever I set them to normally +0.050 to -0.050 it doesn't boot, but if I manually set the voltage 1.13 to 1.23 it works find, sure that's the same or am I missing something? I'm working the 1.13 to 1.23 from the stock 1.18 that it shows me in BIOS. But at the same time CPU-Z and coretemp tell me my VID is 1.26. :confused: I really should read into this some more.

Hey pulse what setting are you using in the d3h bios to offset voltage I cant find it for the life of me, is it under a different name?
 
Right pretty much staying with this, can't be bothered to do any more testing and happy with my results. Max temps 67oc in Intel Burn Test, max temps 55oc in Prime 95. so I know theres 12oc that it'll never rise again.

4.2GHz, 42x100, 1.19v Vcore, 1.75 PLL. Load line - Turbo.

So I had a mess around some more. Determined that 4.4 is the most I'll get out of it with the Corsair A50 CPU cooler, which I dont think is bad for a cooler I payed 20 quid for lol.

I've now turned on all the power saving stuff, so my cpu now clocks down to 1.6 when idle, and vcore drops to 1.068v. Heres the settings I made in bios:

CPU multiplier: 34
turbo mode on, all cores set to: 44
all power saving options on
Loadline Calibration: auto
CPU vcore: Normal
Dynamic vcore(DVID): +0.050

with these settings, my vcore bumps up to 1.320v under load (which is exactly what my CPU needs at 4.4ghz, through previous testing) and drops down to 1.068v when idle (1.6ghz)

Im pretty sure I've found the best performance/power saving I can get, from what I have at the moment.
 
Hey Loque. We should be pc buddies. I have the same chip/mobo and my experience with overclocking has been nearly identical to yours speed, temp and volt wise. It's almost spooky - bar having LLC set to turbo my settings are identical to those you posted above. I experimented with dropping the CPU PLL down to 1.5 which apparently may result in things running cooler, but didn't notice much difference. It was prime stable nevertheless. I'm going to stop here too as there doesn't seem much point in trying to push an average clocker and tbh 4.4 is eating up everything i've thrown at it so far :)
 
I just read this thread and tried it out. With all the standard/default settings my CPU was running 3.8GHz @ 60c fully loaded. I changed the settings to the ones in the first post, and now its running 4.0GHz @ 55c fully loaded. How come it's faster and cooler? Something to do with the Voltage?
 
Bit of a late reply, but it's to do with the default settings using auto voltage which way over compensates for the voltage so that it makes sure that it doesn't cause instability, where as the settings above are fine tuned for the lowest possible voltage for best stability at 4GHz which is going to use a lot less than the auto voltage.
 
I wouldn't advise auto loadline calibration tbh

best test with each one and take into account higher llc level adds more to overall load cpu voltage so use less offset,and low llc usually needs more offset(dvid)

and to unlock dvid for adjustment you first have to set cpu voltage to normal,then add with a + or undervolt the cpu with a -
