DDR3 DIMM
Before installing a memory module, make sure to turn off the computer and unplug the power
cord from the power outlet to prevent damage to the memory module.
DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install
DDR3 DIMMs on this motherboard.
Due to CPU limitations, read the following guidelines before installing the memory in 4 Channel mode.
1. For optimum performance, when enabling Dual Channel mode with two memory modules, we recom-
mend that you install them in the DDR3_1 and DDR3_2 sockets.
