2.5.2 DDR2 Memory Slots

This motherboard provides four 240-pin DIMM slots for Dual Channel DDR2 800 memory modules with memory expansion size up to 8GB.

Hardware Setup

To reach the performance of Dual Channel DDR2, the following rules must be obeyed:

For a 2-DIMM dual-channel installation:

Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], or slots [DIMM3]+[DIMM4].

For a 4-DIMM dual-channel installation:

Populate 2 DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], and another 2 DIMM modules of the same type and size on slots [DIMM3]+[DIMM4].

[DIMM1] and [DIMM2] slots are made of the same color.

[DIMM3] and [DIMM4] are made of another same color.

Usually there is no hardware or BIOS setup requires after adding or removing memory modules, but you will have to clear the CMOS memory first if any memory module related problem occurs.
