Can't push the i5 6600k beyond its limits without issues
I own an MSI Z170M motherboard with an Intel i5 6600K processor. It appears you should easily achieve around 4.3GHz without any voltage changes, but crashes still occur even at 4.1GHz under stress tests, regardless of the voltage applied. I attempted to use Turbo Boost and performed stress tests; it hasn’t crashed yet (4.1GHz boost). Temperatures remain normal, staying below 65°C with a 212x cooler. When setting up the system, I reviewed a few pins but ensured they were properly secured—maybe that’s the cause? My PSU is an 850W RMA850X, so power supply seems adequate.
mazTart:
If it's crashing, your overclock might not be stable. It could be related to the board or power supply. Is the 1.30 stock voltage suitable for that chip? I suggest resetting the BIOS settings in the boot windows to check what CPU is being hit at stock settings. In the manual settings, set the voltage to stock volts—don’t leave it on automatic. I’ve reset the BIOS multiple times without success, but now it’s running at 1.344V with turbo boost 4.1GHz and no issues. Just manually adjust the voltage to stock levels instead of letting it auto.
Yes, you should be able to achieve over 4.3 mainly through the CPU multiplier without any modifications. Just enter the values from the BIOS—such as CPU mult, base clock, voltages, RAM, etc.—to check if there’s an issue.
.. another possibility is that you’ve lost the silicon lotery, and altering the CPU won’t help.

Here are the settings I used before they caused a crash:

These were the configurations I tried, but they still led to issues.
I've also encountered problems installing Intel graphics.
Does it seem unstable? If it's crashing, your overclock might not be stable. It could be related to the board or power supply. Is the 1.30 stock voltage correct for that chip? You should reset the settings in the bios boot windows to check what CPU is being hit at stock settings. In the stock settings manual, set the voltage to the stock volts and stay under 1.30.

I think resetting the BIOS settings in the boot windows might help—check what CPU is being hit at stock settings. In the manual, set the voltage to stock volts; that should keep it under 1.30. I've reset my BIOS multiple times without success, but I'm currently running at 4.1ghz turbo boost with a stable 1.344V.
MazTart asked about stability concerns, suggesting a possible issue with the board or power supply if the system crashes. They inquired about the 1.30 stock voltage for the chip and advised resetting BIOS settings to see what CPU is being hit. MazTart shared that they reset their BIOS multiple times without success, but currently run at 4.1ghz turbo with stable 1.344V. They recommended manually setting the voltage to stock levels instead of automatic and suggested consulting the CPU Z manual for core voltage adjustments.
