Ethminer found my Sapphire R7 370 Nitro 4GB but only shows 3221225472 bytes of memory.
My r7 had 4GB of memory.
I would like to konw why my Sapphire R7 370 4GB only use 3GB of gpu memory.
I am using the last version of ethmine (Ethminer 0.9.41-genoil-1.0.4b3) on operating system is Windows 10 Home.
