Installation Of Memory Modules (Dimm) - ASROCK E3C226D2I User Manual

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.

Installing a DIMM
Please make sure to disconnect the power supply before add-
ing or removing DIMMs or 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.
It is not allowed to install a DDR or DDR2 memory
module into a DDR3 slot; otherwise, this motherboard
and DIMM may be damaged.
If you install only one memory module or two non
identical memory modules, it is unable to activate Dual
Channel Memory Technology.
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.
