Anand "So if I'm reading the Hynix datasheets correctly, that's an 800MHz datarate, which is where the 6.4GBs comes from."
The datasheet is that...
If the memory is 800 datarate (400Mhz) the bandwidth is 6.4GB/s... but I guees he is geting the wrong info... seems like 1600 datarate (800Mhz)... so 12.8GB/s.
Edit - Beyoind3D said it's DDR3-1600 (800Mhz) too http://forum.beyond3d.com/showpost.php?p=1680342&postcount=3263
