So overclocking is something I haven’t explored much, since it wasn’t really necessary for me but I’m now interested.
I own an i5 7640X and it’s basically a temporary solution until I can upgrade to an i7 or i9 later.
I’m trying to figure out what adjustments are needed for an overclock, because I know it’s more than just changing the core ratio—it’s not that simple.
Every article I read gives conflicting advice, with some suggesting voltages like 1.5V and others giving unclear guidance.
The thread I found recommended a 5.1GHz core ratio at 1.35V, but I’m unsure if that’s safe or risky for the chip.
My current specs should be enough to support overclocking.

5GHz at 1.3-1.35V appears normal. Begin by boosting the multiplier while keeping voltage set to auto. Later, adjust voltage differences as needed.

Luckily you received a solid chip, which means you should be capable of reaching 5.1-5.2GHz. Reviewers suggest the X299 version of the Core i5 might clock a bit higher than the standard LGA 1151 model. The absolute maximum for Kaby Lake and Kaby Lake X parts is around 1.4v, though 1.35 is typically average.
