Are the temperatures on your i7 6700k with 1.40v OC and 4.7GHz stable?
Are the temperatures on your i7 6700k with 1.40v OC and 4.7GHz stable?
Hello, I'm attempting to increase my CPU's clock speed for the first time and have seen positive and stable outcomes when raising it from 4.0 to 4.6 GHz at 1.35V. However, I'm encountering difficulties when trying to push it to 4.7 GHz. I experienced a BSOD during that attempt, so I adjusted the voltage to 1.40V but became concerned about overheating. My cores usually stay between the 60s and low 80s at this setting, though they occasionally spike to high temperatures. Last night during a stress test lasting about 30 minutes, one core briefly reached 90°C. I read that for Skylake models, the voltage should not exceed 85°C, but I'm unsure whether this refers to current or maximum temperature. I lowered the voltage to 1.375 and above, but each time I start a stress test, my PC triggers a BSoD. Today's stress test included capturing screens with Aida64 and x264. I'm using a Noctua nh-D15S CPU cooler with an additional fan.

Do you think it's safe to keep running at 1.40V and 4.7 GHz, or should I revert to 1.35V at 4.6 GHz? Thanks for your help.
I would, but you're increasing the voltage, and heat along with voltage tend to be problems. Since the CPU only runs efficiently at low voltages, even a small increase matters a lot. A 100 Mhz clock isn't much, it just sounds impressive. I'd prefer the 4.6Ghz you've managed.
I'm not sure about the exact benefits, ^^; since I'm just starting out with overclocking, I'm worried about damaging my CPU. It might be safer to keep it at 4.6Ghz.
I would, but you're increasing the voltage, and heat along with voltage tend to be problems. Since CPUs operate best at lower voltages, even a small change matters. 100 Mhz might seem fine, but 4.6Ghz is what I'd prefer.
I performed a stress test using X264 all night at 1.375v (1.35v failed) with 4.6Ghz. It ran without crashing, and temperatures stayed in the 50s and 70s most of the time, though one core briefly reached 80°C—still within stable limits for daily use.
I also switched the core voltage override to adaptive mode for regular operation, but I observed the core voltage rising above 1.4v and 1.5v. Is this typical behavior? Didn’t adaptive mode aim to reduce voltage instead of increase it?
I reviewed the thread and found that my power settings were incorrectly set to 'High Performance' during stress testing instead of 'Balanced.' My voltage has improved significantly. Thank you for your assistance.
