Adjusting voltage for the i5 6600k (Tips)
Adjusting voltage for the i5 6600k (Tips)
Hello, your new build includes the ASRock Z170M Extreme 4 with an Intel Core i5 6600K processor. It will be cooled by a Cooler Master Nepton 240M. I’m here to assist with overclocking advice.
I understand adjusting the multiplier in the BIOS, but should I keep the base clock unchanged and just boost the multiplier? Also, I’m unsure about the voltage settings—can they harm the CPU? When should I raise the voltage and by how much? I aim for a stable high overclock that can run reliably for months without adjustments. Could you clarify how much to increase the voltage and when it should be done?
I also have 16GB Corsair Vengeance DDR4 2400MHz RAM installed. Is it correct that you’re enabling X.M.P Profile 1 in the BIOS for the 2400MHz overclock? Do you not adjust the memory voltages during this process?
Thanks, Dean...

Okay, so is anything above too dangerous?
Not really, as long as it's close. But your CPU
WILL
break if you do it too high.
Edit:
And by close I mean CLOSE close. Voltage is a pretty risky thing to play with, but if you do it right, it will become your overclocking best friend. I would say nothing over 1.36V.
You achieve a highly stable performance using a Prime95 v28.9 build at 2 GHz with excellent efficiency. As you progress to higher frequencies, the voltage requirement increases significantly—from around 1.29 V at 4.4 GHz to nearly 1.35 V at 4.5 GHz and up to 6 mV at 4.6 GHz. This steep rise in demand is pushing your CPU to its limits, causing noticeable overheating and eventual failure. I aim for a system that lasts at least three years. It’s important to note that a 25% jump to 4.4 GHz is quite safe, but temperatures will rise considerably as you move into the higher GHz range.
Hello, my recent upgrade includes the ASRock Z170M Extreme 4 paired with an Intel Core i5 6600K processor. The cooling solution will be a Cooler Master Nepton 240M. I require assistance with overclocking.

Additionally, I’m uncertain about the voltage settings—can they harm the CPU? When should I adjust the voltage and by how much? I aim for a stable high overclock that can run uninterrupted for months. Please advise on the appropriate voltage increase and the timing for adjustments.

The only BIOS settings I applied to achieve 4.6 GHz are: CPU VCore at 1.355V, CPU Core Ratio at 46, Uncore Ratio at 45, FCLK at 1GHz, XMP Profile 1, PCH voltage set to 1.00V (default 0.97V), LLC in High, and Internal Graphics disabled. All other parameters remain at their default values.
For the memory, the settings are: System Memory Multiplier at 32, CAS Latency at 15, tRCD at 17, tRP at 17, tRAS at 28, all below 1.28V—standard stock specifications.
My temperatures stay low, around 67°C max during the Intel Burn Test, 52°C in-game, and a consistent 56°C at maximum on Prime95.
