DRAM Clock
The chipset supports synchronous and asynchronous mode between host
clock and DRAM clock frequency.
Settings: [By SPD, 100 MHz, 133 MHz, 166 MHz, 200MHz, 266MHz, 333MHz]
DRAM Timing
The value in this field depends on the memory modules installed in your
system.
Changing the value from the factory setting is not recommended
unless you install new memory that has a different performance rating than
the original modules.
Settings: [Manual, Auto By SPD]
SDRAM CAS Latency [DDR/DDR2]
