BIOS Setup
Adjusted CPU-NB Frequency
It shows the adjusted CPU-NB frequency. Read-only.
CPU Smart Protect±on
CPU Smart Protect±on ±s a mechan±sm of CPU overheat±ng protect±on. It w±ll automat±-
cally reduce the clock when the CPU temperature gets too h±gh.
Unlock CPU Core
Th±s ±tem ±s used to unlock the CPU core. Please refer to the procedures below for CPU
core unlocked ±n BIOS setup.
Success
Enter “OC” and set “Unlock CPU Core” to [Enabled].
Save changes and ex±t the BIOS setup.
System restart.
You w±ll see the “X4” (quad core) or “X2” (dual core for
Sempron ser±es only) dur±ng POST.
Fa±l
Set “Adjust CPU-NB Rat±o” and
“HT L±nk Speed” to [x8].
AMD Phenom(tm) II
X4
Processor
Clear CMOS data.
The CPU does not support CPU core
unlock±ng, please leave the default
sett±ngs for system.

Processor
Important
Th±s CPU core unlocked behav±or depends on the CPU ab±l±ty/ character±st±c, and ±t
±s not guaranteed.
Depend on CPU’s character±st±c, once you get ±nstable scenar±o, please restore the
default sett±ngs for system.
You can also check the core numbers ±n performance tab of W±ndows task
manager.
CPU Core Control
Th±s ±tem allows you to select the number of act±ve processor cores. When set to [Auto],
the CPU w±ll operate under the default number of cores.
AMD Turbo Core Technology
Th±s technology automat±cally ±ncreases the frequency of act±ve CPU cores to ±mprove
performance.
Adjust Max Turbo Core Rat±o
Th±s ±tem allows you to adjust the max turbo core rat±o.
