Question About Core Clock Multiplier and Voltage Reduction Upon Power On
Question About Core Clock Multiplier and Voltage Reduction Upon Power On
I have an i5-9600k that I overclocked to 5 GHz with 1.35v. Initially, I used 1.25v which caused a crash, then increased it to 1.3v and experienced another crash before reaching stability at 1.35v. Benchmarks and gaming showed stable performance without exceeding 80°C. After restarting the next day, the system remained at 5 GHz and 1.35v for roughly 10 seconds post-startup, then dropped to 4.6Ghz and 1.135v. I’m unsure if this relates to the processor’s maximum turbo limit of 4.6Ghz. The BIOS reports a constant 5 GHz and 1.35v, yet temperatures in games matched those from the overclock report. All tests using tools like HWMonitor, CPU-Z, Core Temp, and Task Manager showed it dropping to around 4.6 GHz and 1.135v. I have an MSI Z390 Tomohawk board with the latest BIOS, along with both 8-pin and 4-pin CPU connectors. I’m following the exact settings from MSI’s overclocking guide, except for a lower voltage. I’ve also tried the recommended voltage, but my current configuration is: CPU ratio 50, Ring Ratio 47, Core Voltage 1.350v, Intel C-State disabled, EIST disabled, Turbo Boost disabled, and CPU Loadline Calibration in Mode 3. I forgot to note that my voltage mode overrides and core clock mode is fixed.
