Am I okay to OC at these current temps?

I was just wondering how safe it would be to overclock my system with the current temperatures I'm getting while idle and gaming.

What am I looking at in terms of increased temperature with these current values? That max value was about 1 - 2 hours of gaming. Is CAM even completely accurate with it's readings? Thanks for any answers!

I'm running 1.39 volts to reach 5.0Ghz on a 7700k, 1.4 is usually the safe daily driver max. 1.35 volts is much more reasonable for air cooling.

VID is not the core voltage, by the way. Fire up CPU-Z and see what it is actually getting. (My VID regularly demands 1.5+ volts)

That voltage is high for 4.2Ghz. If you can get higher on the same voltage I guess but you should try to lower that if possible. Voltage of 1.35 is a reasonable voltage for 24/7 operation. At 1.35v it should get you in the ball park of 4.4~4.5Ghz.

Awesome, thanks for the prompt reply. I'm not entirely 100% sure about doing it yet, is that voltage bad to have if I don't OC? I won't also be leaving it up 24/7 as well, shuts down for about 8 - 12 hours a day for the most part.

Agreed that voltage is too high for a 4.2GHZ overclock. Your temps are great BTW. I normally aim for <70C ideally but <85C is in theory good too. It is possible you lost the silicon lottery and need that voltage but my guess is with some tweaking you should be able to get it down to 1.2-1.25V at that clock speed. Though as mentioned as long as you keep to 1.35V or less your good for a 24/7 OC. For the record I got my nephews i7 6700K to 4.4GHZ with 1.225V, 4.5GHZ with 1.285V and 4.6GHZ with 1.35V. I stuck with 4.4GHZ because it was a small case with less then perfect ventilation with an Arctic 240 AIO liquid cooler. With 4.4GHZ OC and his GTX 1070 @ 1893mhz base running both intel burn test on max AND firestrike ultra stress test at the same time his temps would flutter at 75C when I went to 4.5GHZ with the same testing it hit 85C which was too hot for me, even if it was a worst case scenerio test. When just running intel burn test his CPU hit 68C @4.4GHZ and 75C @4.5GHZ

Thanks everyone for all the answers, I'm not exactly sure why I had those max values. My GPU shouldn't have gone up to 1974mhz as it isn't overclocked. I restarted my PC, played Wildlands for about 30 minutes and the numbers were a little different this time. My GPU has it's normal base core clock and now the voltage seems to reach a max of what you guys say is good. I went to the BIOS and all the auto settings for the voltage showed nothing over 1.3, so I assume that is fine? Any reason why I could have had that spike and it showed up higher the first time? Here are some new values that look a little more normal, thanks again everyone!

Edit: As I was typing this, the voltage max seems to be going up slowly (was at 1.35V), even though the current value is sitting at .74-.75. I sometimes see the current voltage spike up to 1.32 - 1.35 every so often from the low of around .72 - .75. I'm confused now, is this normal?

VID is a software generated value of how much voltage the CPU thinks it needs. These are generated by a profile of values stored in each CPU at the factory. That is not what it is actually getting. You need to look at core voltage as I mentioned before.

Tools like CPU-Z, Hardware Info, Hardware Monitor look at core voltage. Core-Temp is another tool that does a good job of showing temperatures, but also displays VID.

Your GPU will exceed its rated specifications as long as temperature and power limits are not exceeded. Look up GPU Boost 3.0.

Thanks Eximo, I figured out a little later on yesterday after looking at CPUID that the VCORE in there is the one you were talking about. I set it manual in the BIOS to 1.300 and it never exceeded that voltage. Since I will probably not be exceeding the 4213MHz that my CPU clocks at now, what voltage do you suggest I set manually in the BIOS?

Also yes, I found out about GPU Boost 3.0 after a quick google search, will probably not be overclocking my GPU either since judging by hardware monitor software, it seems the automatic OC is doing a good enough job on it's own.

Every CPU is a little different. Basically you can try lowering it until the computer crashes.

If you are fixing the voltage, then it may no longer be being reduced while idle. You might want to look into a negative offset value.
