SUPERSERVER 1028UX-LL1-B8/LL2-B8/LL3-B8 User's Manual
Direct Cache Access (DCA Support)
Select Enabled to use Intel's DCA (Direct Cache Access) Technology to improve
data transfer efficiency. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA prefetcher is used with a TOE (TCP/IP Offload Engine) adapter to prefetch
data to shorten execution cycles and to maximize data processing efficiency.
Prefetching data too frequently can saturate the cache directory and delay neces-
sary cache access. This feature reduces or increases the frequency of system data
prefetching activities. The options are Disable, 16, 24, 32, 40, 48, 56, 64, 72, 80,
88, 96, 104, and 112.
X2APIC
Select Enable to activate APIC (Advanced Programmable Interrupt Controller) sup-
port. The options are Enabled and Disabled.
AES-NI
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instruc-
tions (NI) to ensure data security. The options are Enabled and Disabled.
Intel® Virtualization Technology (Available when supported by the CPU)
Select Enabled to support Intel Virtualization Technology, which will allow one
platform to run multiple operating systems and applications in independent parti-
tions, creating multiple "virtual" systems in one physical computer. The options
are Enabled and Disabled.
Note: If a change is made to this setting, you will need to reboot the
system for the change to take effect. Refer to Intel's website for detailed
information.

The options are Disable, Energy Efficiency, and Custom.
If the above is set to 'Custom' the following options are displayed:
CPU P State Control
EIST
EIST (Enhanced 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 (Available when Intel® EIST Technology is enabled)
Select Enabled to use the Turbo Mode to boost system performance. The options
are Enabled and Disabled.
P-State Coordination
This feature allows the user to change the P-State (Power-Performance State)
coordination type. P-State is also known as "SpeedStep" for Intel processors. Se-
lect HW_ALL to change the P-State coordination type for hardware components
only. Select SW_ALL to change the P-State coordination type for all software
installed in the system. Select SW_ANY to change the P-State coordination
type for a software program in the system. The options are HW_All, SW_ALL,
and SW_ANY.
CPU C State Control
Package C-State limit
This feature allows the user to set the limit on the C-State package register.
The options are C0/C1 State, C2 State, C6 (Non Retention) State, and C6
(Rententioin) State.
