i5 6600K Overclocking Help
Hi Guys,
I’m looking for some advice on overclocking my i5 6600K. I previously had a stable overclock at 4.4ghz with a voltage of 1.36v, where temperatures stayed around 70% under full load. Recently, I reset the default settings by mistake and can’t locate that optimal setting anymore.
I’ve managed to get a stable 4.4ghz at 1.365v, but my temps are now reaching 82% during full load. I play a game called P3D, which is quite CPU-intensive—about an hour or two into a flight, my speakers start buzzing and the game freezes. I’m unsure if the overclock is failing or if there’s another issue.
I plan to replace the CPU within the next year since it’s not that old. I’ve read on forums that some users use 1.25v stable at 4.4ghz, so I’m wondering if adjusting the voltage could help lower the temperatures or find a better balance.
I’ll share my stats here:

Any suggestions would be really appreciated.
I think your PC's temperature could be affecting its performance, try running the game alongside a CPU temperature monitor. These applications include a logging feature that can be turned on or off, and during play you can switch via alt+tab to review the readings. Are you using a water or air cooling system?
I'm using a Cooler Master Hyper 212 Plus air cooler without any problems, it's a recent build just after overclocking.
Running the game with CPUID HW shows temperatures near 75 degrees.
Is the current voltage setting still within safe limits?
Your performance depends largely on the luck of obtaining a solid chip.
As of 12/04/2016
How much you can overclock a reasonably stable 1.40v Vcore is unclear.
I5-6600K
4.9 14%
4.8 38%
4.7 67%
4.6 87%
82c appears to be average.
Tell me about your cooler and your case/fan setup.
Any cooler requires fresh airflow to function properly.
If you keep all voltages on auto, that’s the starting point for me.
Adjust your multiplier for all cores to 44 and check the resulting Vcore.
1.4v should reach its maximum.
Keep your RAM at standard voltages; higher RAM voltages seem to reduce the multiplier.
I still don't understand what's leading to the PC freezing and the speakers producing a buzzing noise.
I've taken out and cleaned the CPU fan, RAM, and GPU.
Running Furmark for over 10 minutes without any problems has been successful. I've also completed the Intel Stress Test at all levels without encountering issues. For now, I'm going back to the original settings, but I'll have two new RAM sticks tomorrow just in case. If it doesn't work then I'll have 8GB free.
If my P3D keeps crashing on the default settings, I can be sure it's not the issue caused by me.
It's not really an overclock at 4.4ghz, so issues should be minimal. Keep core speeds and voltages stable by adjusting settings as follows:
LLC set to High
advance voltage settings
vcore between 1.25v and 1.3v
Core 44
Uncore 43
Voltage shouldn't reach 1.3v since you're drawing 100watts... package got Litt =)
Thank you, i'll give it ago, I have created another thread for a different issue so i'll copy it in here in case you know what might be causing it.
Hi guys, my PC has started freezing on me and making a loud buzzing sound through my speakers when playing P3D.
=============================================
Tests Completed so far - OC 4.4ghz @ 1.38v
Prime 95 - Run for 1 hour with no issues.
Furmark - Run for 30 mins with temps being 65 at the most.
Run both at the same time and PC froze.
Changed OC to 4.3ghz @ 1.30v
Attempted to play P3D and crashed again.
I have run a windows RAM test with no issues.
Replaced 2 sticks of 4GB DDR 4 RAM this morning.
Run prime and Furmark together but no crash yet.
CPU temps have hit 82 at the highest.
I have reseated everything.
Cleaned the dust from the PC.
Made sure all the cables are connected properly.
I am also getting a kernel power error 41 in event viewer.

Start by avoiding unnecessary purchases without understanding the issue. Keep things straightforward. Ignore stress tests and similar concerns. Load stock settings and proceed with your regular activities.
