Spare channel mode
In this mode, the channel C is a spare of the two active channels A and B. The
channel C is not available as system memory. The equipping is identical with
the performance channel mode.
●
All three channels must be populated identically with regards to size and
organization.
●
Memory slot populations within a channel do not have to be identical but the
same memory slot location across three channels must be populated the
same way.
●
Can run with differently rated memory modules and use the settings of the
slowest memory module within a channel.
●
Timings in the active channels (A and B) and the spare channel (C) can be
set to different values.
●
Only 2/3 of the maximum memory bandwidth is achievable.
●
The total physical memory available to the system is 2/3 of what is
populated.
