6600K fluctuating baseclock?
I'm experiencing issues with the 6600k OC to 4.5Ghz 100x45 at 1.275v, fluctuating between 4496 and 4503 MHz during idle. The problem persists even though I have EIST, C states, and turbo disabled. I've set it to a fixed solid clock, adjusted performance power settings in Windows, and maxed out the amperage limit. Could it be that the hardware monitoring tool is reporting inaccurately?
It's completely typical and doesn't require concern. This is just a minor frequency variation that won't affect performance. If you notice a significant drop, particularly when under heavy load—which shouldn't happen—that could signal an issue. However, what you're experiencing is within normal limits.
To be frank, I'm still uncertain about the exact cause. Maybe someone with deeper expertise can clarify it for you. Still, the CPU remains actively handling tasks even after most throttling and power-saving settings are turned off. Windows also keeps running background processes, meaning a CPU core is never completely idle for long when using Windows. It's likely that these small operations briefly allocate a core to adjust the clock speed slightly.
I'm not fully confident, but I'm certain these figures are standard and not something to worry about.
