1.4.2 Installing a DIMM
Make sure to unplug the power supply before adding or removing
DIMMs or other system components. Failure to do so may cause
severe damage to both the motherboard and the components.
1. Locate the DIMM socket on the board.
2. Hold two edges of the DIMM module carefully, and keep away of touching its connectors.
3. Align the notch key on the module with the rib on the slot.
4. Firmly press the modules into the socket which will automatically snap into the mounting
notch. Do not force the DIMM module in with extra force as the DIMM module only fits in
one direction.
1.4.3 Removing a DDR5 DIMM
1. Press the two ejector tabs on the slot outward simultaneously, and then pull out the
DIMM module.
Support the DIMM lightly with your fingers when pressing the ejector
tabs. The DIMM might get damaged when it flips out with extra force.
1.5 Expansion Card
In the future, you may need to install expansion cards. The following sub-sections describe
the slots and the expansion cards that they support.
Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.
⚫ A DDR5 DIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a DIMM into a socket to avoid damaging
the DIMM.
⚫ The DDR5 DIMM sockets do not support
DDR/DDR2/DDR3/DDR4 DIMMs.
⚫ DO NOT install DDR/DDR2/DDR3/DDR4 DIMMs to the DDR5
DIMM socket.
