NOTICE!
1. Dual channel function only supports when 2 DIMM Modules plug in either both DDR III 1 &
DDR III 2 or DIMM1 &DIMM2.
2. Memory modules in DDR III 1 & DDR III 2 or DIMM1 &DIMM2 must be of the same type,
same size, and same frequency for dual channel function.
3. DIMM1and DIMM2 is for installing DDR II memory modules only while DDRIII1 and
DDRIII2 is for installing DDRIII memory modules only.
4. User can only install DDRII memory module(s) in DDR II memory module slot(s) when an
AM2 or AM2+ CPU is installed;
5. User can choose either installing DDRII memory module(s) in DDR II memory module slot(s)
or DDRIII memory module(s) in DDR III memory module slot(s), but NEVER both DDRII
and DDRIII memory module(s) at the same time under any circumstances.
Install DDR SDRAM modules to your motherboard is not difficult, you can refer to figure
below to see how to install a 240-Pin DDR II 667/DDR II 800/DDR II 1066 or a DDR III
1066 SDRAM module.
DIMM1 & DIMM2: Dual Channel2
DDRIII1 & DDRIII2: Dual Channel 1
