Turbo Boost Technology
Intel
®
Turbo Boost Technology is featured on certain processors in the Intel
®
Xeon
®
Processor 3400 Series. Intel
®
Turbo Boost Technology opportunistically and automatically
allows the processor to run faster than the marked frequency if the processor is operating
below power, temperature, and current limits. This results in increased performance for both
multi-threaded and single-threaded workloads.

Turbo Boost Technology operation:
Turbo Boost operates under Operating System control – It is only entered when the
operating system requests the highest (P0) performance state.
operating system requests the highest (P0) performance state.
Turbo Boost operation can be enabled or disabled by BIOS.
Turbo Boost converts any available power and thermal headroom into higher
frequency on active cores. At nominal marked processor frequency, many
applications consume less than the rated processor power draw.
frequency on active cores. At nominal marked processor frequency, many
applications consume less than the rated processor power draw.
Turbo Boost availability is independent of the number of active cores.
Maximum Turbo Boost frequency depends on the number of active cores and varies
by processor configuration.
by processor configuration.
The amount of time the system spends in Turbo Boost operation depends on
workload, operating environment, and platform design.

Turbo Boost Technology feature, the BIOS Setup
provides an option to enable or disable this feature. The default state is enabled.
2.4.2.4
Simultaneous Multithreading (SMT)
Most Intel
®
Xeon
®
processors support Simultaneous Multithreading (SMT). The BIOS
detects processors that support this feature and enables the feature during POST.
If the processor supports this feature, the BIOS Setup provides an option to enable or
disable this feature. The default is enabled.

Enhanced Intel SpeedStep
®
Technology
Intel
®
Xeon
®
processors support the Geyserville3 feature of the Enhanced Intel SpeedStep
®
technology. This feature changes the processor operating ratio and voltage similar to the
Thermal Monitor 1 (TM1) feature. The BIOS implements the Geyserville3 feature in
conjunction with the TM1 feature.
