Sapphire 560 4GB, 6pin, Micron (1625 strap to upper) - 14.6/30 dual - EXP/LBRY.
Sapphire 560 2GB, 6pin, Hynix (1500 strap to upper) - 14/29 dual - EXP/LBRY.

The voltage on the Micron gpus is locked, but on Hynix is not. Micron cards are working on 0.935V and I cannot change it. Hynix cards are working on 0.885V and 0.835V.
