CAUTION!
1. Whether 2600/2400/2133/1866/1600MHz memory speed is
supported depends on the CPU you adopt. If you want to adopt
DDR3 2600/2400/2133/1866/1600 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 un-
der Windows®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. xvYCC and Deep Color are only supported under Windows®8
64-bit / 8 / 7 64-bit / 7. Deep Color mode will be enabled only
if the display supports 12bpc in EDID. HBR is supported under
Windows®8 64-bit / 8 / 7 64-bit / 7.

2. Installation
This is a Micro ATX form factor motherboard. Before you install the motherboard,
studythecongurationofyourchassistoensurethatthemotherboardtsintoit.
Pre-installation Precautions
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
Before you install or remove any component, ensure that the
power is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
1. Unplug the power cord from the wall socket before touching any
component.
2. To avoid damaging the motherboard components due to static elec-
tricity,NEVERplaceyourmotherboarddirectlyonthecarpetorthe
like. Also remember to use a grounded wrist strap or touch a safety
grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded anti-
