Notes: 1. When using dual channel mode, install only same (same density, DRAM
technology and DRAM bus width) module for each deal channel.
2. Please note that those types not in the Table B will not boot up.
3. The KN1 Extreme doesn't support three memory modules. If three memory
modules are inserted, the system may boot but not function normally.
