Core Boosting
Core Boosting technology uses a relaxed and optimized turbo profile that adapts the processor to specific
use cases, configurations, and environments. Core Boosting processors take advantage of extra server
power and thermal headroom provided by an innovative HPE voltage regulator design and by cooling
technologies. Consequently, systems that have Core Boosting processors can alleviate common setbacks
and maximize processor computing power.
For example, a processor can have a number of cores and a base frequency at which the cores operate.
Processors may also have a turbo mode that operates processor cores at a faster frequency than the
base frequency. The turbo mode may use thermal and power capacity headroom opportunistically to
operate processor cores at an increased frequency. Turbo mode can increase processor performance
while maintaining the same TDP (Thermal Design Power) level.
Some processors are preconfigured with a TDP and a maximum power level. To maintain these
parameters safely, the predefined settings are typically fused and locked into the processor. These
settings ensure that the processor operates within its standard electrical, thermal, and power design
specifications. A turbo profile for a processor is bounded by these constraints using fixed frequency
registers and core-to-frequency ratio registers. The power limits can be fused to the TDP level. To
maintain the specified TDP level, the CPU turbo frequencies are dictated by the number of active cores
that were fused in core-to-frequency ratio register. The turbo frequency profile scales from all cores active
to a single core active. Accordingly, the turbo frequency increases as the number of active cores being
utilized by lower workload demands or by core parking or disabling technologies.
These fused frequency registers and core-to-frequency ratio registers cap the processor computing
capacity at certain levels. On a general-purpose computing processor, however, you can set the turbo
profile more conservatively to cover various workloads or a worst-case thermal condition. In other words,
the turbo mode might have a one-size-fits-all profile that does not consider the specific configuration or
environment in which the processor operates. Accordingly, the processor might not be tuned to use its full
operating potential.
Setting the redundant power supply mode
Use the Redundant Power Supply Mode option to set how the system handles redundant power supply
configurations. All High Efficiency Mode settings provide the most power efficient operation when you are
using redundant power supplies by keeping half of the power standby mode at lower power usage levels.
Balanced Mode shares the power delivery equally between all installed power supplies.
Prerequisite
Workload Profile is set to Custom.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power and Performance Options > Advanced Power Options > Redundant Power
Supply Mode.
2. Select a setting.
• Balanced Mode—The system shares the power delivery equally between all installed power
supplies.
• High Efficiency Mode (Auto)—The system selects between the odd or even power supply based
on a semirandom distribution within a group of systems.
