Infinity Fabric Frequency and Dividers
Infinity Fabric Frequency and Dividers
Allows you to set Infinity Fabric Frequency (FCLK). Auto = FCLK = MCLK. Manual =
FCLK must be less than 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.
Configuration options: [Auto] [100 MHz] - [3000 MHz]
UCLK DIV1 MODE
Allows you to set UCLK DIV mode.
Configuration options: [Auto] [UCLK=MEMCLK] [UCLK=MEMCLK/2]
