Recommend DIMM Module Combination
1.
One DIMM Module ----Plug in DIMM1
2.
Two DIMM Modules---Plug in DIMM1 and DIMM3 for Dual channel function
3.
Four DIMM Modules---Plug in DIMM1/DIMM2/DIMM3/DIMM4.
For Dual channel Limited!
4.
Dual channel function only supports when 2 DIMM Modules
plug in either both DIMM1 &
DIMM3 or DIMM2 &DIMM4,
or four DIMM Modules plug in DIMM1~DIMM4.
5.
DIMM1 & DIMM3, or DIMM2 & DIMM4 must be the same type, same size, 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 184-Pin DDR266/DDR333/DDR400 DDR SDRAM module looks
like.
DIMM3 (BANK2+BANK3)
DIMM4 (BANK0+BANK1)
DIMM1 (BANK6+BANK7)
DIMM2 (BANK4+BANK5)
DIMM1 & DIMM3: Dual Channel 1
DIMM2 & DIMM4: Dual Channel 2
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.
