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

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

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