GoKawiilHobbyist unlocks all 40 compute units on discounted ASRock BC-250 mining cards
A hobbyist bought two ASRock BC-250 mining cards from AliExpress for £126 and £103 respectively, and successfully unlocked all 40 compute units on both despite AMD's binning meant to disable some cores. One card also unlocked all 8 CPU cores, while the other had one faulty core, but both performed well running the gpt-oss-20b language model via llama.cpp, hitting up to 100 tokens per second at 8K context.
