Intel AES-NI (When supported by the CPU)
Intel® AES instructions are a new set of instructions available beginning with
the the all new 2010 Intel® Core™ processor family based on the 32nm Intel®
microarchitecture. These instructions enable fast and secure data encryption and
decryption, using the Advanced Encryption Standard (AES). The options are Dis-
abled and Enabled.
Simultaneous Multi-Threading (Available when supported by the CPU)
Set to Enabled to use the Hyper-Threading Technology, which will result in increased
CPU performance. The options are Disabled and Enabled.
Active Processor Cores
Set to Enabled to use a processor's Second Core and beyond. (Please refer to
Intel's web site for more information.) The options are All, 1 and 2.
Intel® EIST Technology
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically
adjust processor voltage and core frequency in an effort to reduce power consump-
tion and heat dissipation. Please refer to Intel’s web site for detailed information.
The options are Disable (Disable GV3), and Enable (Enable GV3).

1 - Core Ratio Limit
This increases (multiplies) the processor's core 1 clock speed in relation to
the bus speed. The default setting is 27. Press "+" or "-" on your keyboard to
change this value.
2 ~ 4 - Core Ratio Limit
This increases the processor's core 2~4 clock speeds in relation to the bus
speed. The default setting is 27 for core 2 and 26 for cores 3 and 4. Press "+"
or "-" on your keyboard to change this value.
