did I do okay or am I slowly destroying my cpu? not to experienced with overclocking.
I have it running stable at 4.5 36+hours

i7 4790k
asus sabertooth z97 mark 2
kingston hyper beast 2400 2x8 ram
hyper 212 evo air cooler
corsair cx430 psu (upgrading when I upgrade my gfx card)
all in a corsair 200r budget case with stock fans

lowest idle temps I get is 38 highest i've seen it get up to was around 75. here's a screenie of cpuid hwmonitor so you can see my voltages etc this was underload playing bf4 for about an hour.

Everything looks good. Asus has really nice boards in regards to voltage capabilities. So, if you could lower the voltage and keep it stable you could reduce the overall temps of you build. Cooler temps is always a good thing lol. On the other hand, if you don't want to turn down the voltage then you just OC the CPU till is maxes out the current settings. This would increase temps a little bit, but it would keep the mobo safe from the higher voltage of 1.8V and you get cooler temps and higher clock speed. Seems like a win-win-win to me.

Um, I'm guessing you haven't stress tested at that clock speed and voltage.
Number 1: Lower that voltage immediately. You should never go above 4.5V, 5V you are killing your CPU.
Number 2: You shouldn't need that much voltage at all to reach 4.5Ghz being that stock turbo speed is 4.4Ghz

Your Loadline Calibration (LLC) should be set at the highest (Extreme/Stage 5 or the like). In order to properly OC your CPU you turn up the clock multiplier (or bclk) until it is not stable and then you ever so slightly increase the voltage (Vcore) until it become stable again. All while staying under 4.5V and keeping temps below 70'C preferred.

Update: After each increment up in multiplier and Vcore you have to stress test in order to check to see if it is stable. Use Prime95, OCCT, IntelBurnTest, and Aida64 to have the most stable OC. You can get away with just using Aida64 or Prime95 though. In Prime95 use the small FFTs test to create heat and make sure your temp stay below 70-75'C. Do this for about 10+ min. and then test with the Blend test for 2hrs. This will determine if the OC is completely stable. If at any point if fails before then, it is not stable and you need to readjust. Keep in mind that you cannot OC that CPU as well if much at all with the CM 212 EVO since the 4790K needs really good cooling to OC and not overheat. I have a custom water loop cooling off mine and my CPU is clocked to 4.7Ghz and my water loop stays pretty close to ambient temperatures at all times.

okay well this is another screenshot of hwmonitor with everything in the bios set to default besides dram frequency set to 2133mhz. were you talking about the 5.1v on my motherboard at the very top? I have no idea why its so high like I said everything is on default at this point.
ill get you some screen shots of my bios and see if that helps any.

at this point i'm just going to leave it stock until I upgrade my psu/gfx card then I will look into getting this puppy OC'd if I feel it needs it. still some insight would be nice

@emj: Hey, sorry I read that incorrectly yesterday while I was trying to do homework. Your Vcore is what I'm worried about and I think I confused that with the +5V reading for some reason. I do apologize, but your Vcore seems a bit high still since 1.5V is typically the absolute max that the mobo and the chip can handle in most motherboards. And you would want to stay below 1.4 if possible. Now if you set it to defaults and that is your Vcore then don't bother messing with it for now and see how far you can up the multiplier. If you can adjust your LLC then do make sure that is set to highest setting, this will prevent Vdroop from making the OC unstable.

I appreciate the replys, so the default settings for my mobo has everything set to auto and for whatever reason asus thinks its necessary to run my vcore at 1.800 i cranked it down to 1.500 and everything seems stable so far... anyways I decided not to wait and have a gtx 970 and a new psu on the way and i'm going to mostly likely take another crack at ocing this sucker(again unless i feel it doesn't need it) any ways heres another screenie of hwmonitor. is everything looking okay now at stock? or should I try cranking that vcore down some more and maybe some other voltage settings.
