i7 8700k overclocking
I am just starting with cpu overclocking and have an i7 8700k to try. I followed a guide using an asus e370 extreme board and a asus prime z370-a, mostly doing it. He set 1.3 volts for 4.8V and I was thinking 4.7V on all cores with 1.25V voltage—would that be okay? My bench tests showed temps around 80°C in games, and realbench showed 60-70°C. I also pushed the current and power limits in the bios, as he did it. I’m a bit nervous because I don’t want this overclocking to cause a fire.
Temps are perfect. You don't have to max out power and current limits as you are not doing any extreme overclock. Yet, no harm there since the current and power flow per cpu demand. You ll have to stress test the system for several hours using Prime95 or Aida or both, to claim stability. If the chip does fine 4.7 ghz with 1.25 V then there is some potential there to hit the silicon lottery. OCing is trial and error, every chip is different.
my i8700k operates at 4.8Ghz across all cores using 1.25V and a 200Mhz offset for AVX. I can handle most stress tests, though I rarely run anything longer than two hours. This setup uses an air cooler, but it gets warm during stress tests. Gaming performance is solid.
5.0 GHz with an AVX offset of 0 at 1.23 Vcore under full load, and 5.3 GHz with an AVX offset of 2 at 1.42 Vcore, though it is delidded using 360 AIO
Hi Clyde,
The aim of overclocking is to discover the minimum voltage needed for a specific frequency. Follow these steps:
Let all settings auto-run, then perform a stress test. Record your voltage and frequency, and manually enter them in the BIOS. You’ll have two options:
1°/ Improved performance: Increase the multiplier until it becomes unstable, then adjust voltage (increments of 0.025-0.05V). Once you hit the desired frequency, lower the voltage as much as possible while keeping stability.
2°/ Enhanced thermal efficiency: Maintain the original frequency and reduce voltage to the lowest stable level.
TIPS: Keep voltage below 1.38V and temperature under 85°C during testing for regular use.
