2.3 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
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 the Dual Channel
Memory Technology.

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.

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.
