i7 6700k overclocking trouble
Hi, I'm having trouble clocking past 4.5 ghz with my setup. I have an H100i v2 liquid cooler, an ASUS Z170-A motherboard, and 16GB RAM. My current settings are 1.28 volts at 4.5 ghz, but I'm wondering if it could drop further without testing. Then I tried 4.6 ghz at 1.34 volts and the system crashed after about five minutes. Why is the voltage difference so large when increasing by 100 MHz? Are there any options to push past this gap without going even higher in voltage? My temperatures during stress tests are normal, around 70-80°C, and 25-30°C when idle. Any advice would be helpful.
Obtain a free version of CPUID HWMonitor, launch it and perform benchmarks. At the top, identify the CPU VCORE section; there should be three sets of values. Examine the second one, which shows minimum volts (indicating Vdroop), and compare it with the third value, which represents the maximum voltage. It might be that Vdroop is falling too low. Access the BIOS and modify the settings to raise those figures. Each manufacturer has its own method and terminology for similar adjustments. Consult the motherboard manual for specific instructions. Alternatively, visit a manufacturer’s forum and mention your motherboard model, asking about necessary changes to boost Vdroop, such as enabling all CPU phases.
If booting isn't possible at 4.6Ghz, you likely need a higher voltage. Each processor behaves differently, and I wouldn't exceed 4.5Ghz for regular tasks. To push performance further, try running it at 1.4V with 4.6Ghz. Keep in mind, voltage doesn't increase proportionally at higher frequencies, and it will significantly raise the CPU's heat output—though the H100i should handle it.

Additionally, increase the voltage on your RAM; if it's weak or barely operational at its current setting, this could be the issue. After testing, return the RAM voltage to its original level. Also, ensure you use a reliable power supply unit. A substandard PSU can cause voltage fluctuations that may damage components, leading to crashes, freezes, or hardware failure.
