10Valid Memory ConfigurationsBank 168-Pin DIMM Total MemoryBank 0, 1 (DDR1) DDR200/DDR266 SDRAM Module X1 64MB∼1.0GBBank 2, 3 (DDR2) DDR200/DDR266 SDRAM Module X1 64MB∼1.0GBTotal System Memory (Max. 2.0GB) 2 64MB∼2.0GBNOTE! Make sure the installed memory are DDR266 SDRAM support 133MHz memoryclock, otherwise the system may hang during startup.Generally, installing DDR SDRAM modules to your motherboard is very easy, youcan refer to figure 2-4 to see what a 184-Pin DDR200/DDR266 SDRAM modulelooks like.DDR2 (BANK2+BANK3)DDR1 (BANK0+BANK1)NOTE! When you install DIMM module fully into the DIMM socket the eject tabshould be locked into the DIMM module very firmly and fit into itsindention on both sides.WARNING! For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266-compliant DDR Modules. When this motherboard operate at 133Mhz, mostsystem will not even boot if non-compliant modules are used because of thestrict timing issues, if your DDR Modules are not DDR266-compliant, setthe DDR SDRAM clock to 100MHz to ensure system stability.2-5 Expansion CardsWARNING! Turn off your power when adding or removing expansion cards or othersystem components. Failure to do so may cause severe damage to bothyour motherboard and expansion cards.Figure 2-4
