Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Processor Options > Intel (R) Hyperthreading Options.
2. Select a setting.
• Enabled
• Disabled
3. Save your setting.
Setting the number of enabled processor cores
Use the Enabled Cores per Processor option to specify the number of cores to enable per processor
socket using Intel's Core Multi-Processing (CMP) Technology. Unused cores are disabled. Setting this
option can:
• Reduce processor power usage.
• Improve overall performance for applications that benefit from higher performance cores rather than
more processing cores.
• Solve issues with software that is licensed on a per-core basis.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Processor Options > Enabled Cores per Processor.
2. Enter the number of cores to enable.
If you enter 0, or a value that is not supported by the processor, all cores are enabled.
3. Save your setting.
Enabling or disabling Processor x2APIC Support
When enabled, Processor x2APIC Support helps operating systems run more efficiently on high core
count configurations and optimizes interrupt distribution in virtualized environments. Enabled mode does
not enable x2APIC hardware, but provides the support necessary to the operating system. Unless you
are using an older hypervisor or operating system that is not compatible with x2APIC support, leave this
option enabled. Some hypervisors and operating systems cannot use X2APIC unless Processor x2APIC
Support is set to Force Enabled prior to booting.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Processor Options > Processor x2APIC Support.
2. Select a setting.
