Features Main memory
Mirrored channel mode
Figure 4: Mirrored channel mode
In figure 4 you can see the slots that must be populated for a minimum config-
uration and for the first two upgrades.
In this mode channel A and channel B are exact copies of each other.
● Channel A and channel B must be populated identically (channel C is not
usable in this mode).
● Memory slot populations within a channel do not have to be identical but the
same memory slot location across channel A and B must be populated the
same way.
