Is the overclocking of my i7-6700k suitable for the first time?
Is the overclocking of my i7-6700k suitable for the first time?
This is my initial overclock attempt. I increased the i7-6700k to 4.5 ghz and set the core voltage to 1.325. Using the CM Hyper 612 V2 air cooler, a stress test showed the temperature reached up to 81°C with fluctuations near 75°C according to MSI Afterburner. During idle browsing it was about 55°C and peaked at 61°C. Are these readings acceptable?
As a beginner in overclocking, I just completed my first build two weeks ago and am worried about damaging my PC.
Edit: Switching to SpeedFan instead of MSI Afterburner, it reported 30-40°C during idle and browsing, reaching a maximum of 64°C under load—noisy difference noticed.
those temperatures are a bit high for my preference, along with the voltage. Try to reduce the voltage slightly. Check if it remains stable at 4.5GHz; if not, lower the clocks a bit. Temperatures should drop, and you won’t even notice any performance loss if the chip runs 200 or 300 MHz slower.

the temperatures are a bit too high and the voltage is also not ideal. Consider reducing the voltage slightly. Check if stability at 4.5GHz is maintained; if not, lower the clocks further. Temperatures should drop, and performance loss will be minimal if the chip runs 200 or 300 MHz slower. Please review the edits in my previous post. Is this acceptable now? Or would you prefer to adjust it even more?
60C or even a little more when under load is completely acceptable.
if the system remains stable, you may keep it exactly as it is.
It appears haswell supports vcore up to 1.4v. The maximum achievable speed depends on the chip's quality.
Silicon lottery bins chips and offers better models at a higher price.
As of 2/16/16, the percentage range for overclocking at around 1.40v is:
I7-6700K – 4.8% to 18%
I7-6700K – 4.7% to 56%
I7-6700K – 4.6% to 87%
I7-6700K – 4.5% to 100%

As of 2/16/16, the percentage of users who can successfully overclock at around 1.40v is as follows:
I7-6700K – 4.8%
4.7% – 56%
4.6% – 87%
4.5% – 100%
I’d consider it, but I need to run it stock or it would overheat. It reaches 77°C while playing CS on 1.2V and 4.2GHz.
