X299E-ITX/ac
is is a Mini-ITX 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.
• Make sure to unplug the power cord before installing or removing the motherboard
components. Failure to do so may cause physical injuries and damages to motherboard
components.
• In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
CAUTION:
Please note that X299 platform is only compatible with the LGA 2066 socket, which is
incompatible with the LGA 2011-3 socket (for X99 platform).
1. Before you insert the 2066-Pin CPU into the socket, please check if the PnP cap
is on the socket, if the CPU surface is unclean, or if there are any bent pins in the
socket. Do not force to insert the CPU into the socket if above situation is found.
Otherwise, the CPU will be seriously damaged.
2. Unplug all power cables before installing the CPU.

2.3 Installation of Memory Modules (SO-DIMM)
is motherboard provides four 260-pin DDR4 (Double Data Rate 4) SO-DIMM slots, and
supports Quad Channel Memory Technology.
Quad Channel Memory Conguration
DDR4_A1 Populated
DDR4_B1 Populated
DDR4_D1 Populated
DDR4_C1 Populated
• If only two memory modules are installed in the DDR4 SO-DIMM slots, then Dual
Channel Memory Technology is activated. If three memory modules are installed, then
Triple Channel Memory Technology is activated.
1. For quad channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR4 SO-DIMM pairs.
2. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and SO-DIMM may be damaged.
3. e SO-DIMM only ts in one correct orientation. It will cause permanent damage
to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
