So I just built my new rig. I am new to overclocking but my mobo has a very neat auto overclock feature and has detected that 4.5ghz would be safe and Oc'd to a very stable 4.5ghz.
Idle temps are a lovely 25c under a water block.

Load temps on core 1 after a 10 minute burn in topped at 76c on my coolers quiet setting.

I am wondering if this will be OK long term? I use my pc mostly for gaming so i cant see it
hitting this a lot but I am very conservative and fussy when it comes to degradation.

Guess what I am asking is what kind of load temps should I be aiming for if I want to be absolutely
sure I am not shortening the life of my CPU. I have no problem kicking it down to 4.4 to ensure my CPU will never hit above 65c for example. I guess any kind of heat has the potential to degrade the CPU but I'm looking for a level where this is negligible.

Well my first recommendation is to not use the Auto OC feature. Reason being is it has your voltage bouncing around all over the place. I have seen some users on a auto oc of 4.4 with a voltage of 1.4v which is just absurd. You should be locking your manual voltage in and finding the best stable overclock with the least amount of bump in voltage. While the auto OC feature is nice, I have it with my motherboard also, its quick and simple but not realistic. There is no reason to be running an adaptive voltage or auto voltage when overclocking, as this will also increase temps randomly as the volts jump around, especially at load. My 6700k under 100% load at 4.6ghz never goes above 58C and im also using a liquid cooler. Were almost 20C apart which tells me you may have a slight temp problem. Do you know what your temps were running stock? What is your voltage on your overclock? I would check into these things before you jump into overclocking.

Well I just checked CPUZ and my voltage is indeed jumping around between 0.9 and 1.456. Pre overclock I was maxing at 52C. I think maybe I need to look into this a little more then and not use the lazy way. So it is high voltage that causes heat and degradation? What voltage are you using at 4.6GHz?

Yikes, 1.456V is a ridiculous amount of voltage to be running, especially for long periods. I think 1.45 was the maximum intel said you should run it, after that cpu degradation will take effect. I would remove that oc and do a manual overclock, its just as easy and your temps will not take such a hard hit either. Return to stock, check what your stock voltage is running at, this will give you a baseline of where you need to be working off of. Change your multiplier to the frequency you want to run (for example 45=4.5ghz) and apply to all cores, change core voltage to manual and give it 1.3V to start. Save and reboot. Stresstest for an hour minimum while keep an eye on your temps. Once you can say its stable then you can even go back to your voltage and start bumping it down in increments so that you run the lowest possible stable voltage.

Mine at 4.6ghz is running 1.29V and for 4.5ghz i had 1.26V. Not ever processor is the same and some need more juice then others but I would be really concerned running my PC at such high volts for long periods of time. This is why I would never recommend using the auto oc feature.

Thanks for the advice I will do exactly this. Is 1.3v a nice safe amount for long term then? What do you think would be a good voltage start point for 4.4Ghz? I have no interest in pushing the cpu to its absolute limits but I also know it would be a waste to not overclock such a good chip.

Most people find a stable overclock around the 1.3 areas. For 4.4ghz that SHOULDNT need so much of a bump from stock voltage considering the turbo boost runs at 4.2ghz. First clear any and all changes you have made to your system, then check to see what your stock voltage is showing in your UEFI Bios, this will give you a round about that you should be increasing from. So for example if your stock voltage is 1.2V+ then try the upper hand of 1.2 and lock it in at 1.29V manually. Save it and run a stress test for an hour. Maybe try running a game. If everything is fine then it is considered stable.
