WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the third-
party overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by

CAUTION!
1. ASRock UCC (Unlock CPU Core) feature simplifies AMD CPU activation. As
long as a simple switch of the BIOS 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 CPU only, and
in addition, not every AM3 CPU can support this function because some
CPU’s hidden core may be malfunctioned.
