Cpu i7 7700k 5ghz Overclocking safe Voltage

[7r3evor]

Whats going on guys ok so im looking for a safe long time use for Voltage for my i7 7700k i have my OC Setting set like this here I have a Msi Board it's a Msi z270 m7

mode-expert

Cpu Ratio-5000mhz=5ghzCpu

Core/gtx voltage mode-Adaptive Mode

Enhanced Turbo-Disabled

Intel c States-Disabled

Cpu Core Voltage 1.36
Cpu sa Voltage 1.2
Cpu io voltage 1.1

OK when on Idele Runs At 35c/36c
When on full load playing bf4 runs at 65c-66 spike to 70c Rarely

I don't see a problem for the moment., but you should run tests to make sure it's stable. You can use either prime 95(ver 26.6) or intel xtreme tuning utility. Keeping it below 80C under full load is acceptable.

Wow ran prime 95 and was disappointed because my pc froze lol which means the overclock is not successful do you have any suggestions to help me make this overclock more Stable and whats the most Cpu Core Voltage you would Take a I7 7700k for long time use without killing it the max I've gone with my 7700k was like 1.45 volts and I do understand every chip is different some chips need more voltage some need less

Long time use keep it at 1.4v or below. I had to delid + liquid metal to run anywhere near 1.4v without overheating.

I did not see you mention your cooler?

Ok, that's too high. 1.3-1.35 should be about all the 7700k needs to hit 5ghz. Did you tweak any other voltage settings besides core voltage?
Also, did you make sure it was version 26.6? And run for small FFTs?

I have a nzxt kraken x52 I bought the x62 but couldn't fit 3-120mm fans I liked the look better with the 3 fans on the kraken x52 but I won't be using any of that I just got back my taxes so I've purchased a ekwb supremacy evo waterblock nickel plexi I Actually recived that in the mail today just waiting on the rest of my stuff to come in like my pump and fittings etc
