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

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

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