70 Usually system firmware turns off system memory clock
71 signals to unused SO-DIMM slots to reduce EMI and power
72 consumption.
73 However, some boards do not like unused clock signals to
74 be disabled.

80 If non-zero, this designates the maximum DDR frequency
81 the board supports, despite what the chipset should be
82 capable of.

86 help
87 On some boards it may be neccessary to hard reset early
88 during resume from S3 if the SLFRCS register indicates that
89 a memory channel is not guaranteed to be in self-refresh.
90 On other boards the check always creates a false positive,
91 effectively making it impossible to resume.
