Can I Overclock my i5 6600K to 4.0ghz without touching my CPU Voltage?

[zeal923]

Hello! Title says it all.

Some background info: I haven't touched my CPU (ratio, voltage, etc.) yet. The stock CPU Voltage is 1.168v. The only overclocking-related thing I've done is enable XMP on my ram to enable it to run at its advertised 3200Mhz speed.

My PC: https://pcpartpicker.com/list/3PyGnn

Would I be able to do a low overclock on my CPU to 4.0 GHz without changing my CPU voltage from the stock voltage of 1.168v? (Keep in mind, my CPU's turbo boost clock is 3.9GHz, so I thought OC-ing to 4.0 GHz wouldn't require much change at all).

Thank you!

Maybe...maybe not. Try it out. As long as you do not crank up the voltage to insane levels the worst thing that could happen is freezes, BSODs and restarts. I guess however that you will not be able to get it stable on load at 4Ghz without at least upping the voltage a bit.

Every CPU is different. The chances of running at 4.0 GHz all 4 cores at stock voltage should be high, but not a given. Maybe it would need a bump to 1.2V Such is the Silicon Lottery

Would 1.2 volts be safe? Bottom line is that I want to keep my CPU for a really long time.

Yes, 1.2V is less than 5% increase over the 1.168, 1.28V would be 10% tolerance. I am not too comfortable myself pushing more than 10% for longevity sake. Resistors have a red band 2%, gold band 5%, silver band 10% tolerances. I just use 10% for most electronics functions.

Thank you! What software do you recommend to stress test, monitor temps, etc? My plan is to test out 4.0 ghz without changing anything, and then changing voltage if i encounter a problem. How do I know if there is an issue?

With a single core turbo boost of 3.9Ghz and all 4 core turbo to 3.7Ghz I am not sure you will see any material gain by overclocking to 4.0Ghz

But if i were to OC to this frequency, would I need to change my voltage?

Probably not but every chip is different

Thanks for your response, but I'm a bit confused. Probably not as in "you can't overclock without touching voltage" or as in "you can"?

You can try. There is a good chance 4.0Ghz won't need extra voltage but we cannot say for certain, there is an element of luck if you have a chip that is good or bad at overclocking. Every CPU overclocks differently.

Thank you! What software do you recommend I use to benchmark/stress test? Could you also recommend me to a good overclocking tutorial or youtube video please? Thank you

I OCed my i5-6600k without any change in the voltage to 4,2 ghz and it is running stable (until yesterday for 5 months, because i OCed more 😀). I was using CPU-Z, Core-Temp, and Prime95 with Small FTT's and a Custom Test on 1344K FFTs. Like the others said, its Silicon-Lottery. I would recommend like many posts that you really take your time while doing it. Right now i am at 1.250V with 4,5 ghz and a temperature of 61° Celsius while stresstesting.
