& System Memory Multiplier
Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD
data. (Default: Auto)
& Memory Ref Clock
Allows you to manually adjust the memory reference clock. (Default: Auto)
& Memory Odd Ratio (100/133 or 200/266)
Enabled allows Qclk to run in odd frequency. (Default: Auto)
