Description
Allows the setting of extended configuration options.
Allows override of the detected memory frequency.
NOTE: If SDRAM Frequency is changed, you must
reboot for the change to take effect. After changing
this setting and rebooting, the System Memory
Speed parameter in the Main menu will reflect the
new value.
Controls the CPC/1n rule mode.
Enabled allows the DRAM controller to attempt chip
select assertions in two consecutive common clocks.
Auto = Timings will be programmed according to the
memory detected.
Manual – Aggressive = Selects most aggressive
user-defined timings.
Manual – User Defined = Allows manual override of
detected SDRAM settings.
Corresponds to tRAS.
Selects the number of clock cycles required to
address a column in memory.
Selects the number of clock cycles between
addressing a row and addressing a column.
Selects the length of time required before accessing
a new row.
