Main memory Features
Independent channel mode
Figure 3: Independent channel mode
In figure 3 you can see the slots that must be populated for a minimum config-
uration and for the first two upgrades.
Independent channel mode allows for channels to be populated in any order
and no matching between channels is required.
● All channels in a system will run at the fastest common frequency.
● Can run with differently rated DIMMs and use the settings of the slowest
DIMM within a channel.
● Timings other than frequency can vary between channels.
