Safe core voltage OC i5 8600k
Hello. Your i5 8600k runs at 4.8Ghz with 1.232V and temperatures near 65°C during Cinebench. The motherboard is an MSI Z370 Sli Plus, and you're using XMP with voltage auto. At 5Ghz you see 1,36V.
Consider adjusting BIOS or Windows settings if needed. For safe voltage, stick to the manufacturer's recommended range—typically around 1.0 to 1.2V for this model.
Attempt to maintain around 1.35v to 1.36v, 1.4v is the upper limit and you shouldn’t aim for it. Voltage isn’t a fixed rule; if your motherboard’s load line calibration is enabled at a reasonable setting, it can easily exceed 1.4v during operation. You must check actual readings using tools like CPU-Z or HWMonitor, as setting the board to 1.36v doesn’t reflect real-world performance when the CPU is active. Either the voltage drops sharply to around 1.33v under load and you risk crashing, or it jumps too high to 1.4v+, which is harmful for the processor. You should stress-test the CPU extensively—follow the recommended steps at https://overclocking.guide/stability-tes...-prime-95/ and use the Linx guide (setting 6 threads) at https://obsproject.com/forum/threads/how...linx.5361/. The process is more complex than just booting at 1.36v and running Cinebench; prolonged instability can cause severe errors, data loss, or crashes even after disabling overclocking, often due to corrupted files. Spend several hours testing thoroughly. Begin with Prime95 for initial stress, then use the second guide to confirm stability. If you encounter a BSOD or crash, it means you’re unstable—reduce overclocking immediately. Also, ensure your cooling system is top-tier; these tests push the CPU to its limits. Monitor temperatures closely—stop testing if they exceed 95°C and lower both voltage and overclock settings. Stability matters more than pushing clocks, since frequent errors often go unnoticed until it’s too late.
