Kingston HyperX 4GB DDR3 1600MHz SDRAM Non-ECC 240-pin (KHX1600C9D3K2/4GX) DDR3-1600/PC3-12800

I popped out 6GB of 1333 ram (all on auto) and put in this 12GB of ram, all settings are untouched, all on auto. Seems like some numbers are conflicting.
Thoughts? What do I need to change?
Speed - 1600MHz
Latency - CAS 9
Timings - 9-9-9-27
Voltage - 1.7 – 1.9
