Request Help With OCing 4970K w/MSI Z97 Gaming 5 Mobo Please.

Hi, I've had this build....well the CPU, Mobo, and RAM for a little over a year, my GTX 1070 for about 7 months. Everything is still new to me and I love it; however, I've wanted to tinker with O/Cing my CPU. I've been O/Cing since the Pentium III 800 MHz. I stopped with the Q6600 and had 3 or 4 more CPUs since them. This is my current config.

OK, a little irrelevant history and if you don't care, then just skip to the next paragraph. So I just got the CM Hyper 212 EVO along with the Samsung 850 EVO. My 4970k was running up to 102C at full load using the stock HSF. I'm familiar with O/Cing, I just need a refresher. The main stuff I need help with is the voltage settings. That's one thing I never messed with. The CPU's seem more resilient now, but back in the early 2000's, ppl were breaking cores mounting their HSF's. I was fortunate and I'm overly careful, maybe too careful.

So right now I'm using Intel's Extreme Tuning Utility to get things going and set and then when I've got a stable OC, then I can just input the settings into the UEFI. First, I believe I'm stable running at 4.6 GHz. Ran some stress tests, seem fine and then I' played SWTOR for a few hours. Not the most demanding game, but still. I crash at 4.6GHz. Bear in mind, this is with using the default voltage. I've changed nothing on it. I'd love to get 5 GHz, but is that possible on air? My CPU was too hot running with the stock with Turbo Boost enabled and was reaching 102C and that's when I bought the CM Hyper 212 EVO. That lowered the number down from 102C full load to about 76C full load. Now I'm idling at 30C and the coolest I've seen it was 27C on a much cooler day and I think that's about as cool as it will get with air-cooling. Normal gaming conditions running at 4.6 GHz, I see up to maybe, 73C max. Do you guys think I can hit at least 4.8 or 5 GHz on this thing??

I have XMP enabled on the mobo and Speedstep and Turbo Boost mode enabled. All the tweaking thus far has been done in Windows Intel Extreme Tuning Utility. I know it should be done in the BIOS/UEFI, but I did it this way for two reasons. One, I'm doing it to test it more easily, to see the temps and two, if I crash, it will boot up with it's defaults back on. If, for some reason that doesn't happen, I can always boot into safe mode and disable it. After everything is running stable, I will duplicate my settings in the UEFI, where they should be. So, when I bump up to 4.8 GHz, it crashes. I haven't tried 4.7, but I'm assuming it will be stable for a while but then crash.

It looks like I'm going to have to adjust the voltage, but I'm really not sure what I need to adjust the voltage setting. Using the Intel Extreme Tuning Utility. I see Processor Input Voltage. It's set to Default, which is 1.800 v. Let me just take a screenshot and then post it and have you guys tell me what I should change. Also, with my Cores set to 4.6 GHz each, there's also a Processor Cache Frequency. Right now is set to 4 GHz. Again, my ultimate goal is getting 5 GHz, but not at the expense of instability, reliability and lowering processor lifespan. I'm pretty sure 4.6 GHz isn't going to hurt anything, but 5 GHz and up. Could someone help me with this, please? I made a quick video to show all its features for people to see.

Thanks in advance!

    What software did u use to stress test cpu?
    You aim for 5GHZ with cheapest budget cooler you could find?
    You may hit 4.8 under 212 evo, but temperatures will be very high. I believe around 90C+ during intel burn test with all fans on maximum.
