For 2 x 3200 MHz, 51.2 GB/s is the theoretical limit. I guess your single core is good enough to use all bandwidth. How many RAM sticks do you have?

4 x 32GB for now. I need to investigate manual OC as EXPO doesn't work with all 4 slots populated. Another option is to try the 192GB 4x48GB Corsair kits at 5200.
