These MSI cards may be special. They do use Samsung ram, and not elpida or hynix. There's a good chance the MSI card bios may having tigher memory timings etc which allow higher hashrates.

The only other 280xs i know of that hit this high are those Sapphire Toxic 280xs. I would be highly interested in knowing what brand of ram they use.

can you show your memory @ vbe7 or tahiti gddr5 identifier
