Hi,
i started playing around with OC's for this particular machine:

i5 3570k
MSI Z77a-G43
8gb Corsair Vengeance 1600
Gigabyte Gtx 660 OC
be Quiet! Powersupply

I managed to find the "invisible oc wall" @ 4.4ghz. I just sat the multiplier to 44 and that's basically it. The vcore is on "auto" and i enabled all power saving features (i ran gaming benchmarks and it seems to make no difference at all: in fact it's so close that sometimes the "powersaving" configuration has 1-2 overall fps more than the "all power to the cpu" setup). I went for 4.5ghz with manual set vcore. I ran it with 1.25 but i doesn't look like i can make the system run smooth. I am testing with intel burnintest running 1k tests and playing a 1080p video + running Tomb Raider 2013 benchmarks, surfing the web and let dropbox/skydrive upload stuff (i am not an OC pro but that in my mind this is a setup which needs to run flawless to call it an stable oc). I've read on google that depending on the chip you ran into the "invisible wall" sooner or later. I also saw that the mobo isn't considered good for OC. So my question is what would you do? Call it a day? I guess i got a pretty descent i5 it doesn't go 4.5ghz and above with no further tweeks but since i read about ppl who had to run theirs with 1.3 and more for stable 4.3ghz. Before i forget it. Temperatures. I been checking with 3 programs now and i have contant 57-59 °C @4.4ghz. Idle between 29-34 °C but that's with throttled 2.5-3.0ghz. Anyways i wanted to share my experience a) for advice, b) confirmation and c) there is very little sources out there showing that energy saving options do almost 0 harm, just many people claiming that this and that and this HAS to be disabled for OC. Which from my experience is complete voodoo.

Very good, and yes can prob go higher, the 3570K is pretty good at the OC, but then you hit a wall and it normally takes a healthy vCore increase to jusmp to the next step

Thanks for the reply man! Your sig says you running a 3570k @ 4.7gz on an Asrock. I see how the Z77a-G43 is inferior (originally wanted the G45 but i got the G43 from a local store and wanted to put the machine together and didn't care; the whole rig is basically a "bang for the buck"-machine because i don't do much with it and i gave my old machine to my bro because he couldn't play BF3 with his own and it was painful to watch). Anyways what are your settings to get it to run @4.7ghz?

To provide more details on the OC. I recognized that when i add more vcore and see how the vcore changes overtime (i use the MSI Control Center for that) it fluctuates. I see how one of the power-saving features must be the cause for that. What i wonder about though is that if i set it to 1.25 according to the graph it never ever reaches that high (jumps around 1.20 something or even way less). What i can see though is that even if the tool is not displaying the set vcore of 1.25; raising it seems to raise the maximum vcore to some degree. So my question is: let's assume the cpu would run stable with let's say 1.25 but the fluctuation causes it to run at 1.20 or so from time to time could that cause the OC to be unstable?

It's going to fluctuate, and generally it's besy to OC direct through the BIOS, those software packages are generic and not truly oriented to your particular mobo so the settings aren't as precise as the BIOS, if they actually made the software true to the Mobo, they'd have to update it everytime they update the BIOS
