overclocking i5 6600K to 4.6Ghz is recommended.
Hi all
i just upgraded my pc and need some info.
i've been reading many threads, But never found the answer i was looking for
i have :
Intel i5 6600k Skylake
Gigabyte z170x GAMING 3
16gb DDR4 @ 2666mhz
cooler : H100i (with sp120 Quiet edition fans)
GTX 980 Strix (overclocked it)
250Gb SSD + 2x1TB HDD (no raid)
coolermast 850w power supply
the stock cpu is 3.5Ghz , boost 3.9Ghz
So this is what i did to overclock it :
i adjusted the multiplier to 44 and and it is stable without adjusting the voltages
i used prime95 for couple hours, and had no issues
now i wanted to try to go to 4.6 /4.7 if possible
when i tried 4.6 , i got a blue screen
so i adjusted the vcore to 1.350 . got in windows and tested it with Prime95
i stopped prime95 after half-hour because one core stopped working.. (rest was still testing)
i"ve read that u need to increase the vcore to go further
so i raised the vcore to 1.4v
when running prime95 , one core still stopped working
Im kinda afraid to push it over 1.4V since i want to use my CPU daily
So what do i need to do get it stable?
When i put the multiplier to 45 with 1.4V , i have a stable overclock
The max temperture i had on my CPU is 63 C (145F)

Hello everyone
I just upgraded my PC and need some guidance.
I've been browsing many discussions but haven't found the solution I was seeking.
My setup includes:
- Intel i5 6600K Skylake
- Gigabyte z170x GAMING 3
- 16GB DDR4 RAM at 2666MHz
- Cooler H100i (with sp120 Quiet edition fans)
- GTX 980 Strix (overclocked)
- 250GB SSD plus two 1TB HDDs (no RAID)
- Coolermast 850W power supply
The original CPU runs at 3.5GHz with a boost of 3.9GHz.
For overclocking, I changed the multiplier to 44 and it stabilized without adjusting voltages.
I used Prime95 for a few hours without any issues.
Now I'm aiming for 4.6/4.7 if possible.
When I tried 4.6, I encountered a blue screen.
I then adjusted the Vcore to 1.350 and re-tested with Prime95.
After half an hour I stopped Prime95 because one core failed, but the rest continued testing.
I read that increasing the Vcore further is necessary.
So I raised it to 1.4V.
When running Prime95 again, one core still stopped working.
I'm worried about exceeding 1.4V since I plan to use the CPU daily.
What steps should I take to achieve stability?
When I set the multiplier to 45 at 1.4V, it became stable.
The maximum temperature I observed was 63°C (145°F).

I've heard the most consistent overclock for this model is around 4.4GHz.
In reality, it's better to preserve your CPU and settle for 4.0GHz unless you're willing to risk damage.
It's your investment and your computer, so hope for the best.
Join the Over Clockers Club or similar communities that enjoy overclocking but also aim for peak performance. Have fun!
I'm planning to get the Gigabyte Ga-z170x-Gaming 3 MBo. Have you faced any issues?
I've heard that using multiple memory modules can cause problems.
I'm considering Adata XPG Z1 DDR4 16GB (2x8GB) at 2800MHz, paired with an Intel i7 6700K CPU and a Nvidia GTX 970.
My build is being assembled by CyberPowerPC.
I wouldn't apply a voltage of 1.4V on skylake, aiming to stay below it for any overclocking you might attempt. Doing so would likely cause increased heat and CPU wear for just a few hundred MHz. That doesn't seem worthwhile to me. Stick closer to 1.35 for regular use.
after reading a lot, i chose to stick with 4.4ghz. the only thing i needed to adjust was setting the multiplier to 44. the max cpu vcore tested was 1.249, which is quite solid. i also ran my cpu with prime95 overnight and didn’t see any crashes, giving me a fairly stable overclock. thanks for the advice all.
I adjusted the voltage to auto and after several tests, it stabilized at 4.4. I'm satisfied and confident it won't harm my CPU. Thanks for the advice!
I wouldn't enable auto-voltage settings. Monitor your maximum voltage carefully because auto allows the CPU to overvolt freely when needed. I've noticed users experiencing unsafe voltage levels under load, which is why manual low-voltage settings are safer. Additionally, voltage spikes can raise your temperature. Your OC remains stable now as it can handle whatever voltage is required. Consider reverting to manual or at least adaptive mode so it only applies the maximum needed and reduces when not under load.
4.4Ghz sounds like an ideal frequency for your CPU, I would adjust it to that setting with a manual voltage near 1.3v or as low as it can safely be. After stabilizing, you could increase it slightly by 0.02v just to confirm.
I've previously overclocked several Skylake chips, and they typically reach around 4.4 to 4.7Ghz. Going beyond that often leads to instability or necessitates even higher voltages, usually above 1.4v. Personally, I prefer keeping it under 1.36 to 1.38v.
