s about I7-6700K overclock voltage
Hello everyone,
I've noticed many discussions on this forum regarding overclocking the i7-6700K. I've observed my CPU performing well at 4.7GHZ @ 1.375V. I'm wondering if running at this frequency for continuous use would be suitable for daily gaming. The CPU is currently under 60°C with the Corsair H110i GTX cooler, and I mostly play games on this machine. I might end up keeping it stock indefinitely unless I notice a significant performance drop in games.
Question: Is 1.375V safe to run at 24/7 for 4.7GHZ?
I remember another thread asking the same question, but it was about the i5-6400. Since both use 14nm technology, I assume the voltage requirements are similar. In that case, I wouldn't consider my current settings a long-term solution.
Thanks in advance for your help – it's always appreciated!

The real answer is that no one really understands the safe voltage limit for each CPU on a daily basis. The engineers provide a figure, but it’s always on the cautious side. Voltage can cause damage if it becomes too high or if you fail to manage heat effectively in your VRM. But temperature is actually the main threat to chips.
The real answer is that no one really understands the safe voltage limit for each CPU on a daily basis. The numbers provided by engineers are just conservative estimates. Voltage can cause damage if it becomes too extreme, and failing to manage heat properly can be even more dangerous. Heat, not voltage, is the main threat to chip performance.

nobody really knows the exact safe voltage limit for each CPU every day. The numbers given by engineers are just conservative estimates. Voltage can cause damage if it becomes too high or if you fail to properly manage heat from your VRM. But heat is actually the main cause of chip failure. Regarding cooling for overclocked VRMs on the motherboard, I have a setup with two 140mm fans at the front, one in the back and two at the top of the case. The board I’m using is the ASUS ROG Maximus Hero VIII, so would that provide enough cooling? Also, concerning the CPU, I’m not sure about the problems people are facing with Prime 95. At 4.7ghz running at 1.375V, the system restarted after about 30 minutes. When I checked again after 25 minutes it was fine, but after another 35 minutes it restarted again. I’ve played for around three hours straight without issues, and overclocking tests with Cinebench and games also ran smoothly.
It depends. Choosing liquid cooling removes the heat removal that air cooling provides. If your case flow is sufficient and you're using a maximum hero, you should be fine. Personally, I always keep my VRM's actively cooled during overclocking. If you touch a choke or MOSFET while overclocked and under full load, it can burn your finger—definitely needs airflow. Prime95 becomes more demanding with each run. Heat buildup on VRMs, insufficient voltage, and RAM crashes are likely the main issues. ASUS's RealBench is a solid benchmark for gaming stability, but Prime95 remains the true challenge.

I usually keep my VRM's cool when overclocking now. If you touch a choke or MOSFET while overclocked and under full load, it can burn your finger... they really need airflow.
Prime95 gets tougher with each run. Heat buildup on VRMs, insufficient voltage, RAM crashes—those are likely the main issues. ASUS's RealBench is a solid benchmark for gaming stability. Still, Prime95 is the real challenge.
Could you tell me what settings you'd use with an i7-6700K and 16GB of 2400MHz RAM? For my own testing I run ffts in place, 1344 for minimum and 1344 for maximum.
Regarding the motherboard, I currently have the gigabyte ga-z170-hd3p, but the ASUS model is coming soon. If you're actively cooling VRMs, do you mean adding a waterblock?
Thanks for all the details—it's really appreciated!
I don't have prior knowledge of that particular CPU; only the i5 6600k is familiar. It would be best to search for the exact configurations online. You should also consider using a popular motherboard, which will make finding suitable settings easier. By actively cooling—either by adding a small CPU fan or directing airflow toward the case—you can improve performance.
