ASRock 970 Extreme3 Motherboard
English
CAUTION!
1. ASRock UCC (Unlock CPU Core) feature simplifies 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/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
“Untied Overclocking Technology” on page 27 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 2100/1866/1800/1600MHz memory speed is supported de-
pends on the AM3/AM3+ CPU you adopt. If you want to adopt DDR3
2100/1866/1800/1600 memory module on this motherboard, please refer
to the memory support list on our website for the compatible memory
modules. Non OC mode’s DDR3 1866 is supported by AM3+ CPU.

64-bit OS with 64-bit CPU, there is no such
limitation.
6. For microphone input, this motherboard supports both stereo and mono
modes. For audio output, this motherboard supports 2-channel, 4-chan-

for proper connection.
7. 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 Overclock-
ing, 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 com-
puting performance. Please visit our website for the operation procedures
of ASRock Extreme Tuning Utility (AXTU).
