CAUTION!
1. This motherboard supports CPU up to 95W. Please refer to our website for
CPU support list. ASRock website
2. 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 quadcore 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.
3. Whether 1866/1600MHz memory speed is supported depends on the
AM3/AM3+ CPU you adopt. If you want to adopt DDR3 1866/1600 memory
module on this motherboard, please refer to the memory support list on
our website for the compatible memory modules.
ASRock website
4. Due to the operating system limitation, the actual memory size may be
less than 4GB for the reservation for system usage under Windows® 10
/ 8.1 / 8 / 7 / Vista
such limitation.
5. This motherboard does not support RAID mode under Windows® 10
32-bit / 10 64-bit / 8.1 32-bit / 8.1 64-bit. This motherboard does not
support RAID mode with HDDs of 3TB and above.
