Maximum The Performance of the Dual Channel

To obtain the highest performance of Dual Channel, the configuration of DIMM
must meet the following conditions.
Matched DIMM configuration in each channel
● Same density (128MB~1GB)
As long as you insert memory modules of same density into Channel 1 (DIMM
A1 & DIMM A2) and Channel 2 (DIMM B1 & DIMM B2), dual channel mode will
be enabled.
DIMM A1 + DIMM A2 = DIMM B1 + DIMM B2
Ex: if you insert 1GB memory module into DIMM A1 and DIMM A2, dual channel
mode will be enabled when DIMM B1 + DIMM B2 = 1GB
● Same DRAM bus width (x8 or x16)
● Either single-sided or double-sided
Note: Using memory modules of different chip will
cause system unstable.
When dual channel mode is successfully enabled, the screen will show "Dual
Channel Mode Enabled" while entering POST screens.
