the appropriate frequency automatically. Setting DRAM Frequency can adjust DRAM
Timing.
DRAM Voltage
Configure the voltage for the DRAM Voltage.
Infinity Fabric Frequency and Dividers
AMD Overclocking Setup Set Infinity Fabric frequency (FCLK). Auto: FCLK = MCLK.
Manual: FCLK must be less than or equal to MCLK for best performance in most cases.
Latency penalties are incurred if FCLK and MCLK are mismatched, but sufficiently high
MCLK can negate or overcome this penalty.
