Install The Memory - Foxconn H55A Series User Manual

2-2 Install the Memory

!
Read the following guidelines before you begin to install the memory :
■ Make sure that the motherboard supports the memory. It is recommended that memory
of the same capacity, brand, speed, and chips be used.
■ Always turn off the computer and unplug the power cord from the power outlet before
installing the memory to prevent hardware damage.
■ Memory modules have a foolproof design. A memory module can be installed in only
one direction. If you are unable to insert the memory, switch the direction.

For this motherboard, DIMM(1,2), DIMM(3,4) are two pairs of channels. For Lynnfield
CPU, in each pair of DIMM channel, you need to install yellow DIMM first, then install
black DIMM the second. Black DIMM can not function if no yellow DIMM is installed.
(Please refer to the silkscreen next to the DIMM slots to identify the sequence of
DIMM(1,2, 3, 4) on the motherboard.)
