CAUTION!
1.
ASRock UCC (Unlock CPU Core) feature simplifies AMD CPU activation. As
long as a simple switch of the UEFI option "ASRock UCC", you can unlock the
extra CPU core to enjoy an instant performance boost. When UCC feature is
enabled, the dual-core or triple-core CPU will boost to the quad-core CPU, and
some CPU, including quad-core CPU, can also increase L3 cache size up to
6MB, which means you can enjoy the upgrade CPU performance with a better
price. Please be noted that UCC feature is supported with AM3/AM3+ CPU
only, and in addition, not every AM3/AM3+ CPU can support this function
because some CPU's hidden core may be malfunctioned.
2.
This motherboard supports Untied Overclocking Technology. Please read "Un-
tied Overclocking Technology" on page 38 for details.
3.
This motherboard supports Dual Channel Memory Technology. Before you
implement Dual Channel Memory Technology, make sure to read the
installation guide of memory modules on page 14 for proper installation.
4.
Whether 1866/1800/1600MHz memory speed is supported depends on the
AM3/AM3+ CPU you adopt. If you want to adopt DDR3 1866/1800/1600
memory module on this motherboard, please refer to the memory support
list on our website for the compatible memory modules.

ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to ne-tune
different system functions in a user-friendly interface, which is including
Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hard-
ware Monitor, it shows the major readings of your system. In Fan Control,
it shows the fan speed and temperature for you to adjust. In Overclocking,
you are allowed to overclock CPU frequency for optimal system
performance. In OC DNA, you can save your OC settings as a profile and
share with your friends. Your friends then can load the OC profile to their
own system to get the same OC settings. In IES (Intelligent Energy
Saver), the voltage regulator can reduce the number of output phases to
improve efficiency when the CPU cores are idle without sacrificing
computing performance. Please visit our website for the operation proce-
dures of ASRock Extreme Tuning Utility (AXTU).
