Processor Core Disable (AMD Core Select) NOTE: This feature is available on G7 and Gen8 servers with AMD processors. The Processor Core Disable option allows you to specify the number of cores to enable per processor socket, in multiples of four. Unused cores are disabled. Depending on the applications used, controlling the number of cores to enable has the following benefits: • Reduces processor power usage and improves overall performance • Improves overall performance for applications that benefit from higher performance cores rather than from additional processing cores • Addresses issues with software licensed on a per-core basis. Software licensing issues with enabling or disabling processor core count may exist. For more information, see your software licensing agreement and user documentation. After reading the window with additional information about this option, press any key to display the box in which to enter the number of cores to leave enabled. Options include: • All (default) • User-defined entry, in multiples of 4 Intel Turbo Boost Technology Intel Turbo Boost Technology enables a processor that has available power headroom and is under temperature specification to transition to a higher frequency than the rated speed. Disabling this feature reduces power usage but also reduces the maximum achievable system performance under some workloads. System Options menu 33
