issues with i5 6600k overclocking require assistance
Here is your setup described in a different way:
The system configuration includes an Intel Core i5 6600k running at 3.5ghz, an ASUS 1050ti with 4GB RAM, an ASUS Z170 gaming motherboard, two 8GB Corsair Vengeance RAM modules, a Corsair H100 power supply, and a CX750M power adapter. I aim to achieve a more stable overclock to improve performance beyond the current results. Today’s attempt to reach 4.0ghz using XMP was unsuccessful, as the application crashed during stress testing with ASUS ROG Benchmark. The settings applied were: XMP enabled, all cores synced to 40, and voltage set at 1.350. The default voltage was changed to manual, and I maintained it as high as possible, believing it sufficient.
1.35V is considered mid/high, and 4.0Ghz isn't really a significant overclock since the i5-6600k already reaches 3.9Ghz. If you're okay with 1.35V, try aiming for at least 4.5Ghz. Generally, it's advised not to exceed 1.4V.
You should be able to go higher than 4 ghz... I prefer Asus boards for overclocking, they perform well so I don't think that's the issue. Your cooling and power are good... I:f if it were me, I would increase it to 1.4 and check if you can reach even higher speeds. After reaching a stable OC like 4.4/4.5, try adjusting the power again. Also, you might want to try one of the pre-made Asus OC settings—if that works, it could mean something else needs tuning...

I created a YouTube video comparing my stock settings with what I changed. It would be really helpful if you could watch it and provide your feedback. I’m new to tweaking settings, so following what I found online was my only option.

When I applied the changes shown in the video, my realbench crashed—not the PC itself. Temperatures stayed in the high 60s to low 70s, with a few spikes up to 80. It failed the stress test.
If you need any clarification, I changed these settings:
- Enabled XMP
- Synced all cores and set it to 40
- Kept voltage on auto (still caused a crash)
- Adjusted voltage manually to 1.350 (still crashed)
I didn’t expect a 4.0GHz to work; I just wanted to experience pushing the system. When I play PUGBO on default settings, I get around 3.6GHz with full CPU load.

Could you share a screenshot of the OSC settings page on the BIOS?
Change the Ai Overclock Tuner to manual mode instead of xmp, maintain your RAM speeds at auto or 2133MHz, turn off ASUS multicore enhancement, set the voltage to 1.35v and attempt 40 on all cores once more. Download cpu-z and verify the voltage after booting Windows with 4GHz, then run the test.
