SuperWorkstation 5039D-I User's Manual
Active Processor Cores
This feature determines how many CPU cores will be activated for each CPU. When all
is selected, all cores in the CPU will be activated. (Please refer to Intel's website for more
information.) The options are All and 1, 2, and 3.
Intel ® Virtualization Technology
Select Enable to use Intel Virtualization Technology so that I/O device assignments will be
reported directly to the VMM (Virtual Memory Management) through the DMAR ACPI Tables.
This feature offers fully-protected I/O resource-sharing across the Intel platforms, providing
the user with greater reliability, security and availability in networking and data-sharing. The
options are Enabled and Disabled.
Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware prefetcher will prefetch streams of data and instructions from
the main memory to the L2 cache to improve CPU performance. The options are Disabled
and Enabled.
Adjacent Cache Line Prefetch (Available when supported by the CPU)
The CPU prefetches the cache line for 64 bytes if this feature is set to Disabled. The CPU
prefetches both cache lines for 128 bytes as comprised if this feature is set to Enabled.
CPU AES
Select Enabled to enable Intel CPU Advanced Encryption Standard (AES) Instructions for
CPU to enhance data integrity. The options are Enabled and Disabled.
Boot Performance Mode
This feature allows the user to select the performance state that the BIOS will set before the
operating system handoff. The options are Power Saving, Max Non-Turbo Performance
and Turbo Performance.
HardWare P-States (HWP)
Use this feature to enable or disable hardware P-States support. The options are Disabled
and Enabled.
Intel ® SpeedStep™
Intel SpeedStep Technology allows the system to automatically adjust processor voltage and
core frequency to reduce power consumption and heat dissipation. The options are Disabled
and Enabled.
Turbo Mode
Select Enabled for processor cores to run faster than the frequency specified by the
manufacturer. The options are Disabled and Enabled.

Power Limit 1 Override
Select Enabled to support average power limit (PL1) override. The default setting is Disabled.
Power Limit 2 Override
Select Enabled to support rapid power limit (PL2) override. The default setting is Enabled.
Power Limit 2
Use this item to configure the value for Power Limit 2. The value is in milli watts and the step
size is 125mW. Use the number keys on your keyboard to enter the value. Enter 0 to use the
manufacture default setting If the value is 0, the BIOS will set PL2 as 1.25* TDP.
1- Core Ratio Limit Override
This increases (multiplies) 1 clock speed in the CPU core in relation to the bus speed when
one CPU core is active. Press "+" or "-" on your keyboard to change the value. Enter 0 to
use the manufacture default setting.
2- Core Ratio Limit Override
This increases (multiplies) 2 clock speeds in the CPU core in relation to the bus speed when
two CPU cores are active. Press "+" or "-" on your keyboard to change the value. Enter 0 to
use the manufacture default setting.
3- Core Ratio Limit Override
This increases (multiplies) 3 clock speeds in the CPU core in relation to the bus speed when
three CPU cores are active. Press "+" or "-" on your keyboard to change the value. Enter 0
to use the manufacture default setting.
4- Core Ratio Limit Override
This increases (multiplies) 4 clock speeds in the CPU core in relation to the bus speed when
three CPU cores are active. Press "+" or "-" on your keyboard to change the value. Enter 0
to use the manufacture default setting.
CPU C-States
Use this feature to enable the C-State of the CPU. The options are Disabled and Enabled.
Enhanced C-States
