CAUTION!
1. ASRock UCC (Unlock CPU Core) feature simplifi es AMD CPU activa-
tion. 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 CPU only, and in addition, not every AM3
CPU can support this function because some CPU's hidden core may be
malfunctioned.
2. This motherboard supports Untied Overclocking Technology. Please read
"Untied Overclocking Technology" on page 49 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 19 for proper installation.
4. Whether 2100MHz memory speed is supported depends on the AM3/
AM3+ CPU you adopt. If you want to adopt DDR3 2100 memory module
on this motherboard, please refer to the memory support list on our web-
site for the compatible memory modules.

7. F-Stream is an all-in-one tool to fi ne-tune different system functions in a
user-friendly interface, which currently includes Hardware Monitor, Fan
Control, Overclocking, OC DNA, Mouse Polling and IES. In the Hardware
Monitor mode, F-Stream shows the major readings of your system. In
Fan Control mode, F-Stream shows the fan speed and temperature for
you to adjust. In Overclocking Control mode, F-Stream allows you to
overclock the CPU frequency for optimal system performance. In OC
DNA mode, you can save your OC settings as a profi le and share them
with your friends. Your friends can then load the OC profi le in to their own
system to get the same OC settings. In Mouse Polling mode, F-Stream
allows you to adjust the mouse polling rate of the Fatal1ty Mouse port to
add a professional level mouse confi guration. In IES (Intelligent Energy
Saver) mode, the voltage regulator can reduce the number of output
phases to improve effi ciency when the CPU cores are idle without sacri-
fi cing computing performance.
