This item allows the user to set the
frequency the memory runs at. If this item
is set to 100MHz, make sure to use PC-
100 compliant DIMM modules. If this
item is set to 133Mhz, PC-133 compliant
modules have to be used. Setting this item
to a higher frequency than is supported by
your SDRAM DIMM modules may lead
to system crashes.
Note: Only the 810E chipset supports
this Feature.
