- Important: Non-ECC or ECC Registered memory cannot be mixed within the ASRock X99 Extreme4

- Higher frequency memory (measured in MT/s) will clock down to run at optimal speed within your ASRock X99 Extreme4 Motherboard
 depending on processor model and number of modules installed.

- Please note Mhz is always half of MT/s.
MT/s is the abbreviation for megatransfers / million transfers per second and is the more effective way to measure DDR4 memory frequency.- Install identical modules for best performance. For example if your model has 2 slots, purchase 2 modules for best performance and Dual-Channel mode.

- Can i mix the memory capacity per slot in my ASRock X99 Extreme4 Motherboard? Yes. This is a commonly asked question and you can mix capacities but best performance comes from installing indentical DDR4 modules.
