Recommend DIMM Module Combination
1. One DIMM Module ----Plug in DIMM1
2. Two DIMM Modules---Plug in DIMM1 and DIMM2 or DIMM3 and DIMM4 for Dual
channel function of 4-DIMM Design motherboard and Plug in DIMM1 and DIMM2 for
Dual channel function of 2-DIMM Design motherboard.
3. Four DIMM Modules---Plug in DIMM1/DIMM2/DIMM3/DIMM4.
For Dual channel Limited!
1. Dual channel function only supports when 2 DIMM Modules plug in either both DIMM1 &
DIMM2 or DIMM3 &DIMM4, or four DIMM Modules plug in DIMM1~DIMM4 of 4-DIMM
motherboard and 2 DIMM Modules plug in DIMM1 & DIMM2 of 2-DIMM Motherboard.
2. DIMM1 & DIMM2, or DIMM3 & DIMM4 of 4-DIMM motherboard, and DIMM1 &
DIMM2 of 2-DIMM motherboard must be the same type, the same size, and the same
frequency for dual channel function.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 240-Pin DDR2 400

/ 533 / 667

/ 800 SDRAM module looks like.
NOTE!
When you install DIMM module fully into the DIMM socket the eject
tab should be locked into the DIMM module very firmly and fit into its
indention on both sides
DIMM1 & DIMM2: Dual Channel 1
DIMM3 & DIMM4: Dual Channel 2
