System BIOS
47 Setting up BIOS on 15th Generation (15G) Dell EMC PowerEdge Servers | 508
Note: This option is only available on systems
with Intel processors.
Determinism Slider
• Power Determinism
• Performance Determinism
It controls whether BIOS will enable
determinism to control performance.
Performance - BIOS will enable 100%
deterministic performance control. Power -
BIOS will not enable deterministic
performance control.
Note: This option is only available on systems
with AMD processors.
Efficiency Optimized
Mode
• Enabled
• Disabled
Efficiency Optimized Mode maximizes
Performance-per-Watt by opportunistically
reducing frequency/power.
This field enables/disables Efficiency
Optimized Mode.
Note: This option is only available on systems
with AMD processors.
Algorithm Performance
Boost Disable (ApbDis)
• Enabled
• Disabled
When enabled a specific hard-fused Data
Fabric (SoC) P-state is forced for optimizing
workloads sensitive to latency or throughput.
(For higher performance) When disabled P-
states will be automatically managed by the
Application Power Management, allowing the
processor to provide maximum performance
while remaining within a specified power-
delivery and thermal envelope. (For power
savings)
Note: This option is only available on systems
with AMD processors.
ApbDis Fixed Socket P-
State
• P0
• P1
• P2
• P3
This value defines the forced P-state when
ApbDis (Algorithm Performance Boost
Disable) is enabled.
Note: This option is only available on systems
with AMD processors.
Dynamic Link Width
Management (DLWM)
• Forced
• Unforced
DLWM reduces the XGMI link width between
sockets from x16 to x8 (default), when no
traffic is detected on the link. As with Data
Fabric and Memory Pstates, this feature is
optimized to trade power between core and
high IO/memory bandwidth workloads.
Forced = Force link width to x16, x8, or x2.
Unforced = Link width will be managed by
DLWM engine
