Yes, this is a world record, i have the third best binned V1 ever

2.6x stock (1020->2601MHz)

Done on the more inefficient Erista model which is built on 20nm instead of Mariko that is built on 16nm

No, i can't increase voltage more due to Switch OS blocking me

No, I can't go further

NOTE: this is done on a CUSTOM build of Horizon OC. NONE OF THESE clocks are making it into actual release builds. If you want to try this yourself you must compile it yourself
