elpida or Hynix my sapphire dual x R9 270 uses hynix and i currently oced it to 1100/1500 at 1285mv and 20% power limit can i oc mem further 1500 ( 5.6 gbps ) on that card
Can try, that's the only way to tell, the memory is same as the GPU itself, different chips of the same model will be different, some OC well others won't
