CAUTION!
1. ASRock UCC (Unlock CPU Core) feature simplifies AMD CPU
activation. As long as a simple switch of the UEFI option “AS-
Rock 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. Whether 2100/1866/1800/1600MHz memory speed is sup-
ported depends 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.
