Should I get a 16GB (2x8) 2400mhz CAS11 ram memory or a 16GB (2x8) 1866mhz CAS9 ram memory?
My motherboard is an asrock z97 extreme 6 and its ram specs are the following:
- Dual Channel DDR3/DDR3L Memory Technology
- 4 x DDR3/DDR3L DIMM Slots
- Supports DDR3/DDR3L 3200+(OC)/2933(OC)/2800(OC)/2400(OC)/2133(OC)/1866(OC)/1600/1333/1066 non-ECC, un-buffered memory
- Max. capacity of system memory: 32GB*
- Supports Intel® Extreme Memory Profile (XMP) 1.3 / 1.2
- 15? Gold Contact in DIMM Slots

Thanks!

You would have to check the through put on your specific motherboard. Ram operates different on different motherboards. Each manufacturer has specific speeds that they do better at.
