NB Frequency Multiplier This option appears only when you adopt Phenom CPU. However, for safety and system stability, it is not recommended to adjust the value of this item. HT Bus Speed This feature allows you selecting Hyper-Transport bus speed. Configuration options: [Auto], [x1 200 MHz], [x2 400 MHz], [x3 600 MHz], [x4 800 MHz] and [x5 1000 MHz]. HT Bus Width This feature allows you selecting Hyper-Transport bus width. Configuration options: [Auto], [8 Bit] and [16 Bit]. Unlock CPU Core UCC (Unlock CPU Core) feature simplifies AMD CPU activation. As long as a simple switch of the BIOS option "Unlock CPU Core", 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 AM2+ / AM3 CPU only, and in addition, not every AM2+ / AM3 CPU can support this function because some CPU's hidden core may be malfunctioned. Memory Configuration Memory Clock This item can be set by the code using [Auto]. You can set one of the standard values as listed for DDR2 memory modules: [200MHz DDR2_400], [266MHz DDR2_533], [333MHz DDR2_667] and [400MHz DDR2_800]. If you adopt Phenom CPU, there is one more option: [533MHz DDR2_1066]. You can set one of the standard values as listed for DDR3 memory modules: [400MHz DDR3_800], [533MHz DDR3_1066], [667MHz DDR3_1333] and [800MHz DDR3_1600]. DRAM Voltage Use this to select DRAM voltage. Configuration options: [Auto], [1.794V] to [2.201V]. The default value is [Auto]. 37

Unlock CPU Core
UCC (Unlock CPU Core) feature simplifies AMD CPU activation. As long as a
simple switch of the BIOS option “Unlock CPU Core”, 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
AM2+ / AM3 CPU only, and in addition, not every AM2+ / AM3 CPU can
support this function because some CPU’s hidden core may be
malfunctioned.
