Memory Clock
This item can be set by the code using [Auto]. You can set one of the
standard values as listed: [400 MHz (DDR3 800)], [533 MHz (DDR3 1066)],
[667 MHz (DDR3 1333)] and [800MHz (DDR3 1600)].
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for
memory compatibility when it is set to [Enabled].
Memory Controller Mode
It allows you to adjust the memory controller mode. Configuration options:
[Unganged] and [Ganged]. The default value is [Ganged].
Bank Interleaving
Interleaving allows memory accesses to be spread out over banks on the
same node, or accross nodes, decreasing access contention.
Power Down Enable
It allows you to enable or disable DDR power down mode.
Channel Interleaving
It allows you to enable Channel Memory Interleaving. Configuration options:
[Disabled], [XOR of Address bit [20:16, 6]], [XOR of Address bit [20:16, 9]],
[Address bits 6] and [Address bits 12]. The default value is
[XOR of Address bit [20:16, 6]].
CAS Latency (CL)
Use this item to adjust the means of memory accessing. Configuration
options: [Auto], [3CLK], [4CLK], [5CLK] and [6CLK]. The default value is
[Auto].
TRCD
Use this to adjust TRCD values. Configuration options: [Auto], [5CLK] to
[12CLK]. The default value is [Auto].
