Overclocking i5 4690k
Overclocking i5 4690k
Hey, it's not unusual for the system to show a slight variance when checking overclock settings. The BIOS and ASRock tools confirm the base frequency is set to 4.6GHz, so the current reading of 4.55GHz might be normal due to minor fluctuations or background processes. Voltage levels should support 4.6GHz without issues.
You won't always achieve the exact theoretical frequency in the BIOS, but it should be close enough.
The 1.4 volts setting is higher than ideal; however, your CPU may degrade faster, so you can usually just lower the clock speed and reduce the voltage.
I suggest aiming for around 1.3V and any stable frequency at that level.
Additionally, using SPEEDSTEP (or similar) will cause the Task Manager to display a fluctuating frequency since it adjusts voltage and speed accordingly.
Intel doesn't appear to have significant latency problems with core parking that would require turning off power-saving options. Those features also help extend CPU lifespan.
The silicon selection, CPU cooler, power supply, and motherboard VRM components will influence overclocking performance, though the charts indicate that a 4.8GHz setting at 4.25 volts leads to crashes. The most stable speed recorded was 4.7GHz at 1.3V. This is what I mean when I say your voltage settings are on the higher end.
