1. Whether 2450/2100MHz memory speed is supported depends on the AM3/AM3+
CPU you adopt. If you want to adopt DDR3 2450/2100 memory module on this
motherboard, please refer to the memory support list on our website for the compatible
memory modules. ASRock website: http://www.asrock.com
2. Due to the operating system limitation, the actual memory size may be less than 4GB
for the reservation for system usage under Windows® 8.1 / 8 / 7. For Windows® 64-bit
OS with 64-bit CPU, there is no such limitation. You can use ASRock XFast RAM to
utilize the memory that Windows® cannot use.
3. Please plug the power cable to the PCIe power connector only when you install three or
more VGA cards.
