Bought a 12900K instead of the 12700K, and it was a complete disappointment with an SP68. Found the 12900KS for almost the same price, so I returned the K and got the KS with an SP96. It’s way faster, but with stock BIOS settings on the Z690i, it throttles. Any good guides for overclocking or undervolting it, especially if it's already close to maxing out?
