What is Core Clock Multiplier and Voltage Lowering After Startup?
What is Core Clock Multiplier and Voltage Lowering After Startup?
I have an i5-9600k that I pushed to 5 GHz with only 1.35 volts. At first, I tried 1.25v but it crashed, so I went up to 1.3v and another crash happened there too. Finally, I got it running at 1.35v without crashing. After testing games and looking around, everything worked fine and the heat never went over 80 degrees Celsius.
When I shut down and restarted tomorrow, something weird started happening. The processor stayed at 5 GHz and 1.35v for about ten seconds after it turned on, then suddenly dropped to 4.6 GHz and 1.135v. I don't know if this is related to the setting or not, but the maximum speed my CPU supports is actually only 4.6 GHz.
I'm confused because in the BIOS, it still shows 5 GHz and says 1.35v, even though in the games and software like HWMonitor, CPU-z, Core Temp, and Task Manager, it always reports as 4.6 GHz and around 1.135v. I have an MSI Z390 Tomohawk board with the latest BIOS (I used the same revision when it worked before). I also have both the 8-pin and 4-pin CPU connectors plugged in.
My settings are exactly what the MSI guide suggested, except my voltage is lower than theirs. I already tried their recommended voltage too. My setup looks like this: CPU ratio = 50, Ring Ratio = 47, Core Voltage = 1.350v, Intel C-State = Disabled, EIST = Disabled, Intel Turbo Boost = Disabled, CPU Loadline Calibration Control = Mode 3. Just forgot to mention that my voltage mode is set to override and my core clock mode is fixed.
