DRAM DIMMs installation order

This section contains information of how to install DRAM DIMMs properly.
Independent memory mode installation order
In independent memory mode, memory channels can be populated with DIMMs in any order and you can
populate all channels for the processor in any order with no matching requirements. Independent memory
mode provides the highest level of memory performance, but lacks failover protection.
Independent Mode
Independent mode provides high performance memory capability. You can populate all channels with no
matching requirements.
Independent memory mode guidelines:

interface frequency.
