Innity Fabric Frequency and Dividers
AMD Overclocking Setup Set Innity 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 suciently high
MCLK can negate or overcome this penalty.
