y Modules (DIMM)

This motherboard provides four 240-pin DDR2 (Double Data Rate 2) DIMM slots,

and supports Dual Channel Memory Technology. For dual channel configuration,

you always need to install identical (the same brand, speed, size and chip-type)

DDR2 DIMM pair in the slots of the same color. In other words, you have to install

identical DDR2 DIMM pair in Dual Channel A (DDRII_1 and DDRII_2; Yellow slots;

see p.2 No.8) or identical DDR2 DIMM pair in Dual Channel B (DDRII_3 and

DDRII_4; Orange slots; see p.2 No.9), so that Dual Channel Memory Technology

can be activated. This motherboard also allows you to install four DDR2 DIMMs for

dual channel configuration, and please install identical DDR2 DIMMs in all four

slots. You may refer to the Dual Channel Memory Configuration Table below.

Dual Channel Memory Configurations

(1) Populated Populated - -

(2) - - Populated Populated

(3)* Populated Populated Populated Populated

* For the configuration (3), please install identical DDR2 DIMMs in all four slots.

1. If you want to install two memory modules, for optimal compatibil-

ity and reliability, it is recommended to install them in the slots of

the same color. In other words, install them either in the set of

yellow slots (DDRII_1 and DDRII_2), or in the set of orange slots

(DDRII_3 and DDRII_4).

2. If only one memory module or three memory modules are in-

stalled in the DDR2 DIMM slots on this motherboard, it is unable to

activate the Dual Channel Memory Technology.

3. If a pair of memory modules is NOT installed in the same Dual

Channel, for example, installing a pair of memory modules in

DDRII_1 and DDRII_3, it is unable to activate the Dual Channel

Memory Technology .

4. It is not allowed to install a DDR memory module into DDR2 slot;

otherwise, this motherboard and DIMM may be damaged.

Dual Monitor Feature

This motherboard supports dual monitor feature. With the internal dual VGA output

support (DVI-D and D-Sub), you can easily enjoy the benefits of dual monitor feature

without installing any add-on VGA card to this motherboard. This motherboard also

provides independent display controllers for DVI-D and D-Sub to support dual VGA

output so that DVI-D and D-sub can drive same or different display contents.

Besides, this motherboard also supports HDMI output option. In the motherboard

giftbox package, you can find one bundled DVI-to-HDMI converter, which is used to

transfer HDMI signals to HDMI devices through VGA/DVI-D port. As long as you

connect the DVI-to-HDMI converter to the VGA/DVI-D port on the I/O panel, your

motherboard will be able to support HDMI signal. Therefore, you can also enjoy the

dual VGA output function through VGA/D-Sub and VGA/HDMI ports.
