The SO-DIMM Socket
The A1SAi & A1SRi supports up to 32GB of Unbuff ered DDR3 ECC SO- DIMM
1600/1333 MHz (1.35V/1.5V) memory in 4 slots.
Memory Population Guidelines
Please follow the table below when populating the A1SAi & A1SRi Series mother-
board.

1. Install the desired number of SO-DIMMs into the memory slots, starting with
DIMMA1, then DIMMB1, then DIMMA2, then DIMMB2. Pay attention to the notch
along the bottom of the module to prevent incorrect DIMM module installation.
2. Insert each SO-DIMM module vertically and snap it into place. Repeat step 1 until
you complete the memory installation. See more information on the SO-DIMM
socket to the left of this QRG.
1. Align the key on the bottom of the SO-DIMM module against the receptive point
on the memory socket. Take note of the notches on the side of the SO-DIMM
module, and of the locking clips on the socket to avoid causing damage.
2. Install the SO-DIMM module straight down into the socket until it is securely
seated in the socket. The side clips will automatically lock the module into place.

Removing the SO-DIMM Memory Module
Use your thumbs to gently push the side clips near
both ends away from the module to release it from
the socket. Once the module is loosened from the
socket, pull the SO-DIMM module upwards.

(*Do not use the 4-pin DC power @J1 when the 24-pin ATX Power @JWP1 is connected
to the power supply. Do not plug in both J1 and JPW1 at the same time.)
