So, 4790K is still a fine CPU but juuuust starting to get long in the tooth. Want to eke more out of it. I'm on an Asus Z97A UEFI BIOS - and I've had misfiring results with overclocking. I can get 4.5GHz but only by ramping the voltage up to around 1.450 and even then it's not overly stable. I can't help but feel I'm missing the subtlety to do this properly. I'm discovering the cache voltage, ring (or something, dunno what it's called in my bios) cpu input voltage, LLC, and a bunch of other stuff which I'm struggling to use to good effect. So, short and sweet - how do I get up to 4.7 (which this chip is supposed to do comfortably) and keep it stable? I've looked up guides but they all say different things and few seem to cater for this motherboard. Incidentally my cooler is a Corsair H60. Idle temps in summer (when really warm as it is right now in UK) are around 30-45. Load is roughly 70C without OC. Uses shin etsu btw. Advice please! And appreciated.
