D2619 (RX/TX300 S5) Technical Manual 23
Features Main memory
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.
● 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.
