<title>SPEC CPU2017 Platform Settings for NEC Express5800 Intel-based systems</title>

<firmware>
<![CDATA[

<p><b>Firmware Settings</b></p>
<p>One or more of the following settings may have been set. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.</p>


<p><b>Thermal configuration (Default = Optimal Cooling):</b></p>
<p>Use this option to select the fan cooling solution for the system. Optimal Cooling provides the most efficient solution by configuring fan speeds to the minimum required speed to provide adequate cooling. Increased Cooling runs fans at higher speeds to provide additional cooling. Select Increased Cooling when third-party storage controllers are cabled to the embedded hard drive cage, or if the system is experiencing thermal issues that cannot be resolved. Maximum cooling provides the maximum cooling available on this platform. Enhanced CPU Cooling runs the fans at a higher speed to provide additional cooling to the processors. Selecting Enhanced CPU Cooling may improve system performance with certain processor intensive workloads.</p>


<p><b>Enhanced Processor Performance Profile (Default = Disabled):</b></p>
<p>Use this option to enable the Enhanced Processor Performance setting. When enabled, this option will adjust the processor settings to a more aggressive setting that can result in improved performance, but may result in a higher power consumption.  Note that higher per server power consumption could decrease server density in power constrained enclosure and rack configurations.</p>


<p><b>Power Regulator (Default = Dynamic Power Saving Mode):</b></p>
<p>You can only configure this option if the Workload Profile is set to Custom. Use this option to configure the following Power Regulator support:
- Dynamic Power Saving Mode: Automatically varies processor utilization. Enables the reduction of overall power consumption with little or no impact on performance. Dose not require OS support.
- Static Low Power Mode: Reduces processor speed and power usage. Guarantees a lower maximum power/performance state at all times, regardless of the OS power management policy.
- OS Control Mode: Processors run in their maximum power/performance state at all times unless the OS enables a power management policy.</p>


<p><b>Minimum Processor Idle Power Package C-State set to Package C6 (non-retention) State (Default = Package C6 (retention) State):</b></p>
<p>You can configure this option only if the Workload Profile is set to Custom. Use this option to select the lowest idle package power state (C-state) of the processor. The processor automatically transitions into package C-states based on the Core C-states in which cores on the processor have transitioned. The higher the package C-state, the lower the power usage of that idle package state. (Package C6 (retention)is the lowest power idle package state supported by the processor).</p>



<p><b>Workload Profile (Default = General Power Efficient Compute):</b></p>
<p>Select this option to change the Workload Profile to accommodate your desired workload. Settings that are changed by the Workload Profile are grayed out and unchangeable unless in the 'Custom' profile. Please refer to the 'UEFI Workload-based Performance Tuning Guide' for details on which profiles affect which option.</p>
