1.7.2 DDR2 Memory Slots
To reach the performance of Dual Channel DDR2, the following rules must be obeyed:
•
For a 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [
DIMM1
]+[
DIMM2
], or slots
[
DIMM3
]+[
DIMM4
].
•
For a 4-DIMM dual-channel installation:
Populate 2 DIMM modules of the same type and size on slots [
DIMM1
]+[
DIMM2
], and
another 2 DIMM modules of the same type and size on slots [
DIMM3
]+[
DIMM4
].
※
[
DIMM1
] and [
DIMM2
] slots are made of the same color.
[
DIMM3
] and [
DIMM4
] are made of another same color.
Usually there is no hardware or BIOS setup requires after adding or removing memory modules,
but you will have to clear the CMOS memory first if any memory module related problem
occurs.
To install system memory:
1.
Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2.
Locate the DIMM slot on the board.
3.
Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4.
Align the notch key on the module with the rib on the slot.
5.
Firmly press the module into the slots until the ejector tabs at both sides of the slot
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.
6.
To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
※
Static electricity can damage the electronic components of the computer or
optional boards. Before starting these procedures, ensure that you are
discharged of static electricity by touching a grounded metal object briefly.
