System BIOS—System Profile Settings
The System Profile Settings menu provides various System Profiles to target for performance, performance-
per-Watt, or RAS for dense configurations to facilitate different customer workloads.
Note: The default option setting is depicted in boldface. Dell EMC reserves the rights to change the default
properties.

Description
System Profile
• Performance per Watt
(DAPC)
• Performance per Watt (OS)
• Performance
• Workstation Performance
• Custom
Enables you to set the system profile. When
set to a mode other than Custom, BIOS will
pre-set each option accordingly. When set to
Custom, you can change the setting of each
option.
Performance Per Watt Optimized (DAPC)
Enables BIOS to manage the processor power
states in order to achieve Performance/Watt
maximized at all utilization levels and
workload types while still meeting
performance requirements. The BIOS also
manages system Power Capping in this mode.
Detailed settings for AMD and Intel platforms
are descripted in section 1.10.1 and 1.10.2.
Performance Per Watt Optimized (OS)
In this mode, the CPU Power Management
field is set to OS DBPM. Implies that the OS
controls the processor’s power management.
The main controls are the processor
frequency or performance states (aka P-
states, P0, P1…Pn), and the processor clock
throttling (aka T-states, T0, T1…Tn). The OS
modifies the power states to achieve the best
operating performance, based on the Node
Manager inputs and the processor utilization.
Detailed settings for AMD and Intel platforms
are descripted in section 1.10.1 and 1.10.2.
Performance
In this mode, the CPU Power Management
field is set to Performance and allows the
BIOS to program the processor for the
maximum performance state.
Custom
In this mode, you can change the settings of
individual options. The following sections will
describe each option in detail.
