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

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