Flashing Radeon Vega 64 BIOS into Vega 56 Does Increase performance

It’s been topic of discussion with pretty much any AMD Radeon releases, can a cheaper product in the same range use a BIOS from its bigger brother?

For Vega is was clear from the get-go that flashing the Vega 64 BIOS into the Vega 56 model would not unlock the extra shader processors. In fact flashing that BIOS wasn’t even possible. However with some bypasses it now has been achieved.

As you can see, the results are interesting, if you flash the 64 BIOS into the 56, the shader processor count indeed does not ryze (pardon the pun). However the performance does. It seems that that the 64 has been tweaked a bit allowing different limiters on power and heat, and that combined with the higher 64 clock frequencies in the end will bring a bit more performance.

ALSO people have been flashing the LCS (water-cooled) BIOS into the 64, and that increase performance a bit as well.

In the end, the 56 reference cards should be able to take the 64 settings, as really it is the same stuff. But with anything BIOS related, please do be careful.

Is it just me or does something not add up with Vegas performance.

I've been thinking about this since the release.

The thermals are quite OK, even for the reference model, so I have no idea where those 300W+ go.

Btw.: New here, hi all :-)

Raising the voltage limitations and power threshold probably helps nicely, guessing that's good for third party GPU models whenever those actually come out.

(Availability on the stock models are already pretty poor though, these are probably going to be even worse so yay? )

I think that AMD could be "afraid" that unlocking this extra performance could kill the card early, so they unlock it only on the best batches.

Edit: welcome Vananovion :-)

Yeah read this two days ago and shared it in the Vega thread. Still, free performance with a vBIOS flash usually has it's fans and applications
