2.2 Installation of Memory Modules (DIMM) ALiveNF4G-DVI motherboard 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_2; Yellow slots; see p.2 No.6) or identical DDRII DIMM pair in Dual Channel B (DDRII_3 and DDRII_4; Orange slots; see p.2 No.7), 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) (Yellow Slot) (Orange 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_2), or in the set of orange slots (DDRII_3 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_3, 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. English 10 ASRock ALiveNF4G-DVI Motherboard
