DDR2 Controller Ref Voltage
Possible values of an option:
[Auto], [DDR2_Vol/2], [DDR2_Vol/2-30mv], [DDR2_Vol/2-20mv], [DDR2_Vol/2-10mv], [DDR2_Vol/2+10mv], [DDR2_Vol/2+20mv], [DDR2_Vol/2+30mv]
The option description:
Allows to correct a ratio of level of logical zero to logical unit for the storage controler. If you are not engaged in acceleration, value [Auto] will be an optimal choice. If needed to lift accelerating potential of a subsystem of storage it is possible to try to "play" a difference between levels of logical signals, raising thus a memory bus noise immunity.
