On the PCIE-Q350, each channel is interfaced to two 240-pin DIMM sockets in the
following order (see Figure 5-7 above):
Channel A: DIMM1 and DIMM2
Channel B: DIMM3 and DIMM4
When populating the DDR2 DIMM sockets, populate them in the following order to
optimize the memory performance:
Step 1: DIMM1. Install the first DDR2 DIMM into the DIMM1 DDR2 DIMM socket.
Step 2: DIMM3. Install the second DDR2 DIMM into the DIMM3 DDR2 DIMM socket.
Step 3: DIMM2. Install the third DDR2 DIMM into the DIMM2 DDR2 DIMM socket.
Step 4: DIMM4. Install the fourth DDR2 DIMM into the DIMM4 DDR2 DIMM socket.

5.4.3.3 DIMM Installation Guidelines
To install a DIMM into a DIMM socket, please follow the steps below and refer to
Figure 5-8.
Step 1: Open the DIMM socket handles. The DIMM socket has two handles that
secure the DIMM into the socket. Before the DIMM can be inserted into the
socket, the handles must be opened. See Figure 5-8.
Step 2: Align the DIMM with the socket. The DIMM must be oriented in such a way
that the notch in the middle of the DIMM must be aligned with the plastic bridge
in the socket. See Figure 5-8.
