Infinity Fabric Frequency and Dividers
Set Infinity Fabric frequency (FCLK) Auto: FCLK = MCLK. Manual: FCLK must be ≤
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] [667MHz] - [4000MHz]
ECO Mode
ECO Mode
Configuration options: [Disable] [Eco-Mode (65W)]
Precision Boost Overdrive
Precision Boost Overdrive
When this item is enabled, it allows the processor to run beyond the defined values for
PPT, VDD_CPU EDC, VDD_CPU TDC, VDD_SOC EDC, VDD_SOC TDC to the limits
of the board, and allows it to boost at higher voltages for longer durations than default
operation.
Configuration options: [Auto] [Disable] [Enable] [Advanced]
The following items appear only when Precision Boost Overdrive is set to [Advanced].
PBO Limits
[Auto] Loads AMD default socket power (PPT), electrically-limited VRM
current (EDC), and thermally-limited VRM current (TDC) limits.
[Disable] Disabled PBO limits.
[Motherboard] Allows the processor to run according to increased PPT, EDC,
and TDC limits defined by your motherboard.
[Manual] Allows the processor to ignore AMD default limits for PPT, EDC,
and TDC and instead use manual values (up to the maximum
capabilities of the motherboard).
The following items appear only when PBO Limits is set to [Manual].
PPT Limit [W]
This item allows you to adjust total CPU socket power delivery capability. Adjustable
up to the limit supported by your motherboard.
Configuration options: [0] - [65535]
TDC Limit [A]
This item allows you to adjust peak current from your motherboard’s CPU core VRM
phases in thermally-limited scenarios. Adjustable up to the limit supported by your
motherboard.
Configuration options: [0] - [65535]
EDC Limit [A]
This item allows you to adjust peak current from your motherboard’s CPU core VRM
phases in electrically-limited scenarios. Adjustable up to the limit supported by your
motherboard.
Configuration options: [0] - [65535]
