2.5 Installation of Memory Modules (DIMM)
This motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install two identical (the same brand, speed, size and chip-
type) memory modules in the DDR3 DIMM slots to activate Dual Channel Memory
Technology. Otherwise, it will operate at single channel mode.
1. It is not allowed to install a DDR or DDR2 memory module into a
DDR3 slot; otherwise, this motherboard and DIMM may be
damaged.
2. If you install only one memory module or two non-identical
memory modules, it is unable to activate Dual Channel
Memory Technology.
3. Some DDR3 1GB double-sided DIMMs with 16 chips may not
work on this motherboard. It is not recommended to install them
on this motherboard.
Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only ts in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.
