Chip Hell Flashes Vega 56 BIOS with Vega 64 BIOS
 

Long story short is that kdtree over at ChipHell as successfully BIOS flashed a Vega 56 card with the Vega 64 BIOS, however it did NOT allow him to get access to the stream processors in order to "unlock" those. However it did give him enough room to run the Vega 56 at Vega 64 clocks. As you can see above, this put the Vega 56 very close to a stock clocked Vega 64.
