the gigabyte z390 gaming x is capable of overclocking an i7 8700k at 5ghz with a 1.35vcore? what are those pins in the top right near the xmp led that aren't listed in the manual? i haven't done any overclocking yet, and i'm planning to test lowering the vcore. do you have any recommendations for a starting vcore value? also, what are your thoughts on the mobo?

Instead of focusing on the ideal 5 GHz operation, let's explore what clock speeds can be reached while maintaining stability at the default core voltage. Start with all cores operating at 4.7 GHz, then gradually increase by 100 MHz each time, checking for stability. Eventually, a slight adjustment in core voltage might be necessary to push further, but temperatures rise rapidly at that stage. Would you prefer 4.8 or 4.9 GHz with 75°C temperatures, or raise the core voltage and aim for 93°C to reach the desired 5 GHz, achieving only a 1-2 frame speed boost in tasks limited by 90% GPU performance?

It's a 10+2 Power phase design, which should work well for overclocking, though it isn't the sole limiting factor. It also depends on the CPU, cooler, power supply, and other components. My personal experience with Gigabyte motherboards isn't extensive.

on the upper right there are some pins, i wasn't referring to cpu 12v pins, i have a Coolermaster ML240L as my cooling solution

I prefer the cooler choice, thank you for the suggestion.
