How hot is 84 degrees for a 6700k oscillator at 4.5 ghz?
Hey guys, just checking in about overclocking. I'm aiming for 4.5 ghz on my 6700k, but I need at least 1.43 volts to avoid crashes during stress tests with OCCT. My CPU is hitting a max temperature of 84°C under the test, wondering if that's too high?
Maybe you lost the silicon lottery, generally most i7-6700k would do 4.5Ghz under 1.4V. nothing you can do really, the voltage is too high for such meagre gain.
Voltage levels are excessively high; I would not exceed 1.425V for extended periods, which is beyond safe limits for 4.5Ghz.
Too high voltage, I wouldn't exceed 1.425V for extended periods and that's beyond what's suitable for 4.5Ghz. That's exactly my concern. If I lower it to 4.4Ghz, I can maintain stability at 1.375v, which is significantly lower than 1.43 and still operates at a manageable 79 degrees. I just don't get why the jump from 4.4 to 4.5 demands so much power for stability.

My suggestion would be to remove the coating and apply some liquid metal, as I have mine at 4.7 and 1.35v where temperatures reach 80°C under load. Delidding reduced the temperature by around 15-20°C for me. Curse that toothpaste TIM! It seems you missed out on the silicon opportunity sadly.
What method are you using to keep your chip cool? Regarding the silicon lottery, can you return the chip and receive an improved one? I had a similar issue where my chip wasn't performing well. Since I purchased it from NewEgg, they processed the return and sent me a replacement that worked much better...

what kind of delidder would you suggest? I own a 6700k that would really benefit from a delidding process. They do have some options on eBay, but I went the traditional route—used a razor blade, added electrical tape for better grip, and nutted it up. Youtube also has tutorials for delidding a 6700k.
