The original K7 Athlon processor arrived inmid-1999and put AMD on equal footing with rival Intel for the first time.

The first models were cartridge-based, designated Slot A, and proved to be quite overclockable.

Core voltage for that OC was 1.80, and I had the cache divisor set at 12.

AMD hid a fun Easter egg on its Athlon K7 CPU that went undiscovered until now

Load temps only increased about six degrees Fahrenheit with the OC and voltage boost.

Years ago, Microsoft included a specialEaster eggprinted on the PCB of the Xbox One.
