Dell Processor Acceleration TechnologyIntroductionDell Processor Acceleration Technology (DPAT), enabled through the BIOS, provides a better performing solution than turning turbo off to force the processor to operate at the lowest base frequency, while maintaining a more consistent turbo frequency state. DPAT minimizes transition duration when the processor functions in turbo mode, thereby decreasing jitter and allowing for lesser latency. The following Dell PowerEdge systems with Intel E5-2690 processors installed, support DPAT..PowerEdge System Minimum BIOS Version Minimum iDRAC Firmware VersionR720 R720xd R6201.4.8 1.4.8 1.4.81.30.30 1.30.30 1.30.30Enabling DPATTo enable DPAT on your system, make the following changes in the BIOS setup. 1 Set the required number of cores:a bPress F2 to enter the System Setup menu. In the Processor Settings screen, set the Number of Cores per Processor to the required value. NOTE: The maximum turbo frequency increases with fewer cores enabled.2 Make the required changes in the BIOS System Profile using one of the following methods. • or2013 - 03Set System Profile in the BIOS setup to Performance mode.•Make the changes using the System Profile Custom selection. • • • Set System Profile in BIOS to Custom mode. Set CPU Power Management to Maximum Performance mode. Set Turbo Boost mode to Enabled.You must enable DPAT with a controlledturbo command using one of the following modes: • • • Dell Remote Access Controller Admin (RACADM) Web Services for Management (WSMAN) Dell OpenManage Deployment Toolkit (DTK)Enabling DPAT Using RACADM (Firmware RACADM: SSH or Telnet Session)NOTE: Ensure that LC and CSIOR are enabled before performing the configuration. 1 Set ControlledTurbo to Enable by running the following command: $ racadm set bios.procsettings.controlledturbo Enabled 2 Create commit and host reboot jobs by using the jobqueue command: $ racadm jobqueue create BIOS.Setup.1-1 -r pwrcycle -s TIME_NOW -e TIME_NA 3 Reboot the server and run CSIOR for the setting to take effect. NOTE: The BIOS settings only take effect after you reboot the server and run CSIOR. Attribute value names are case sensitive.Disabling DPAT Using RACADM (Firmware RACADM: SSH or Telnet Session)1 Set ControlledTurbo to Disable by running the following command: $ racadm set bios.procsettings.controlledturbo Disabled 2 Create commit and host reboot jobs by using the jobqueue command: $ racadm jobqueue create BIOS.Setup.1-1
