Intel's 3000 series (Ivy Bridge) processors did not have integrated voltage controllers built in to the processor yet at that time. That came later with the Haswell family of chips. So 3770K (And all 3000 series / Intel Ivy Bridge processors) all rely on the voltage controller / VRM section of the motherboard they are installed in. So if you install a 3770K in a motherboard like the MSI Z77A-G41 (6-phase power) which is just barely the minimum for installed processors to function at all, then you will be seriously limiting the CPU's potential overclocking ability.
In fact I would go so far as to advise not overclocking too much on that motherboard. Due to it's limited VRM design you could potentially damage the motherboard if it's overclocked too far.
It doesn't even have a heatsink on the VRM components at all either. I'm going to go out on a limb here to sawdust3d and guess your system's processor was running really hot at one point, and that's why you bought the water cooler for it, yes? That's probably due to the weak VRM design and lack of heatsink on the vrm components on this board which would be causing the power section to run hot, which then bleeds heat in to the cpu socket and artificially overheating the cpu as a result.
EDIT: For those wondering. A photo of OP's motherboard from the MSI website: https://asset.msi.com/resize/image/global/product/five_pictures2_2625_20140408101934.png62405b38c58fe0f07fcef2367d8a9ba1/1024.png
I spent last night benchmarking the stock spec amongst other things. Learened quite a bit.
Found this rather detailed MSI Bios tweaking/OC walkthrough. It's not exaclty my hawdware or Bois version, but the presenter gets into many of the BIOS settings available in the MSI BOIS interface that appear to be rather important/helpful in getting a good stable OC. Such as calibrating the load line.
If anyone wants to give it a gander, the OCing part is around 47 minutes in.

So here's a question: I'm seeing that CPU Cotre #3 is consistently say 5C higher temp, on average, under load (stress test). As that will be the limiting factor in the OC, is there any school of thought to setting the voltages by core and limmiting the weak core slighly to bring it inl ine with the overall curve?
You can't set the voltage per core on 3000 series chips, that's a feature of later chips. Personally, if you do want to overclock on this board I would just suggest setting it to 44x multiplier in bios (on all cores) and just try for something like 1.35v cpu voltage (Vcore) and set CPU VTT to 1.20v (do not raise that any higher, that is the maximum for ivy bridge) and disable any loadline calibration/LLC options in bios and just try for it and see if it works. Try a few benchmarks like firestrike, and personally I try wprime 1024m test and cinebench a few times. I would advise you -NOT- use Prime95 or any of those other tests. They're pointless and they serve to make the chips run hotter than they ever possibly would under normal gaming conditions.
For an overclock myself I just run 3dmark firestrike 1-3 times and wprime about 1-3 times back to back and use my phone's stopwatch and do cinebench R15 about 10~12 times back to back. And a final test I do is download a youtube video in 4K and use handbrake to down-sample it to 1080p as that should put the cpu @ 100% load for about 30 minutes and is a good example of something else I do: compressing gameplay recordings for youtube.
If 1.35v isn't stable you may try for 1.40v cpu v-core, and I would suggest staying below 1.40v on your setup, that should be your maximum. If it works at 1.35v then try running with it for a few days and if you don't see any crashes anywhere then try lowering it to like 1.30v and if a few days no crashes, lower it again.
However: I will warn you again that it's a very basic motherboard you have there, and a high potential to physically burn out the board's power section overclocking on it. Do so at your own risk and I won't be responsible if you do try it.
AAAAAHHHhhhhhh...It's All Your Fault!
Kidding....thanks for the warnings; if I wasn't comfortable with the risks I wouldn't even be messing around with it.
You hit the nail on the head with many points there. The depth of control in that bios(v2) is pretty bare. The power mutiplier has a limmited range of setings topping out at about 1.336v - 1.352v under load. That turns out to be the limmmiting factor.
At that voltage, I have what appears to be a stable OC at 4600MHz. Temps weren't an issue. A few hours into the AIDA64 Stability Test my worste single core temp was 76C. 3DMark Firestrike Extreme stability test temps never leave the 60s.
Thanks again, let you know if I melt anything.
^^ They're still a great CPU. There's not a whole lot of reason to upgrade.
I don't want to hijack your thread but.. if you want a comparison.. this is a photo of my Z77 motherboard 's power section. I took a few photos when I had it disassembled for converting it to full-board water cooling.

And this board allows voltage settings all the way up to 2.5v for cpu, which.. is liquid nitrogen territory, but it still allows it.
Currently I'm only at 1.60v on mine and it's enough to keep my i5-3570K stable @ 5.1 ghz. I do plan to be upgrading it to a 3770K in a few months, around summer 2019 and I'm expecting at least 5.0 ghz, more like 5.2~5.3, due to this motherboard.
Rock solid stable overclock to 4.4 Ghz.
I use the ASrock extreme tuner to overclock.
If your motherboard manufacturer has overckocking software then use it to try and find stable overclocks. Ideally the BIOS is the place to change it but it means a lot of reboots to eventually
find the stable values you are happy with.
The CPU is still working surprisingly well for gaming after nearly 7 years.
Just a suggestion. Even though the i7-3770k is still a good CPU, getiing a comparible overclock compared to your i5-3570k may be difficult. Maybe wait until the new AMD processors are available. It seems even the low end ones will beat an i7-3770k.
Nope, it's this motherboard. I've now had three different I5-2500K's in it, and all 3 of them did 5.0 ghz, 5.1 ghz, and 5150 Mhz in this board. I had a 2600K for a while and it did 5275 Mhz in this board, and now my 3570K does 5.1 Ghz in it. I actually had the 3570K running at 5.3 ghz for a while but it wants 1.80v for cpu vcore to be stable and even with 4 radiators and running the 3570K bare-die in a big custom water loop with 2 pumps it couldn't cool it, was hitting mid-90's C and had to dial it back to 5.1 ghz @ 1.60v for temperatures. Averages mid-70's under max now turned down to 5.1, which is more acceptable. Board is GA-Z77X-UP7, go search for it in google. Everything I install in it runs at at-least 5 Ghz, usually a little above. That's why like I was trying to say above to the OP that your maximum overclock with Ivy Bridge / 3000 series has -WAY- more to do with the motherboard and it's power section design than silicon lotto. Silicon lotto matters more with later chips.
I actually had an i7-5820K @ 4.4 ghz for a while on X99 and I went backwards to this Z77 platform recently. I'm expecting to go to 3770K and once I get that clocked to 5.0~5.3 ghz I don't think I'll be upgrading to anything newer. I was looking for something Intel that can reliably hit 5.0 ghz and my options were either this crazy motherboard for Z77 and older chips, or something in the coffee lake line (8700K or 9900K). I only spent so far $400 for everything for this board + 3570K + ram (I got a deal on a set of nice 2133 16GB kit with water block on the ram) vs I was looking at around $1200 for board + CPU + a 16GB set of 3600 Mhz DDR4 for the newer system. Even if I spend $200 on a 3770K in a few months I'll still be ahead.
3770K is fast enough for any modern game with any modern video card, once overclocked high enough.
The only difference where 8700K is any faster is in heavily multi-threaded workloads like video editing, video converting, etc, due to being 6 cores vs 3770K's 4 cores. But most games don't use more than 4 cores still in 2018. In actual gaming performance, in games, they're almost equal, at the same clocks.
the VID is rated for 1.52V max. so you litterally fry the CPU and highly degrade it. But well at least it is cheap to replace.
That is funny, cause video show otherwise.
