2.5 Installation of Memory Modules (DIMM)

ConRoeXFire-eSATA2motherboard provides four 240-pin DDRII (Double Data Rate II) 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) DDRII DIMM pair in the slots of the same color. In other words, you have to install identical DDRII DIMM pair in Dual Channel A (DDRII_1 and DDRII_3; Yellow slots; see p.11 No.7) or identical DDRII DIMM pair in Dual Channel B (DDRII_2 and DDRII_4; Orange slots; see p.11 No.8), so that Dual Channel Memory Technology can be activated. This motherboard also allows you to install four DDRII DIMMs for dual channel configuration, and please install identical DDRII DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration Table below.

Dual Channel Memory Configurations

	DDRII_1	DDRII_2	DDRII_3	DDRII_4
	(Yellow Slot)	(Orange Slot)	(Yellow Slot)	(Orange Slot)
(1)	Populated	-	Populated	-
(2)	-	Populated	-	Populated
(3)*	Populated	Populated	Populated	Populated

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

1.If you want to install two memory modules, for optimal compatibility 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_3), or in the set of orange slots (DDRII_2 and DDRII_4).

2.If only one memory module or three memory modules are installed in the DDRII 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_2, it is unable to activate the Dual Channel Memory Technology .

4.It is not allowed to install a DDR memory module into DDRII slot; otherwise, this motherboard and DIMM may be damaged.

5.If you plan to use ATITM PCI Express VGA card on this motherboard, the total system memory size should be above 512MB.
