Installingmemory
The next step is to install the memory modules. Once again, ground yourself
to the power supply or chassis each time before you touch the motherboard
or a memory module.
The Intel DX58SO motherboard has four memory sockets that accept 240-pin
DDR3 memory modules (DIMMs). The black memory socket (nearest the pro-
cessor) is Channel A, DIMM 1. Moving toward the front edge of the mother-
board, the three blue sockets are Channel A, DIMM 0, Channel B, and Channel
C, respectively.
If you have a set of three memory modules that are identical in speed and
capacity, install them in the three blue memory slots. If you have two matched
modules, install them in memory slots B and C. If you have only one memory
module, install it in slot C.
To install a memory module, first ground yourself by touching the power
supply or case chassis. Swing the pivoting latches open on both ends of the
memory socket(s) you intend to use. Remove the module from its packaging,
and position it as shown in Figure 5-35 with both edges of the module aligned
with the slots in the memory socket.
Memory modules and sockets are keyed with a notch in the contact (bottom)
edge of the memory module and a matching nub in the socket that prevent a
memory module from being installed backward. Verify that the key is aligned
properly on the module and socket, and then use both thumbs to press down
firmly on the module, as shown in Figure 5-36, until the module seats com-
pletely in the socket.

Align the memory module with the socket

Press down firmly to seat the memory module in the
socket
As the memory module seats in the socket, the pivoting latches at both ends
of the socket should swing back up into the latched position, engaging the
slots in the center of the edges of the module, as shown in Figure 5-37. If the
pivoting latches don't move into latched position on their own, move them
into place manually. (Note that the latch on the rear module in Figure 5-36 did
not engage. We subsequently latched that one manually.)
