102-4 Install MemoryThis motherboard provides three 168-pin DUAL INLINE MEMORY MODULES(DIMM) sites for memory expansion available from minimum memory size of64MB to maximum memory size of 3.0GB SDR SDRAM.Valid Memory ConfigurationsBank 168-Pin DIMM Total MemoryBank 0, 1 (DIMM1) PC133 SDR SDRAM Module X1 64MB∼1.0GBBank 2, 3 (DIMM2) PC133 SDR SDRAM Module X1 64MB∼1.0GBBank 4, 5 (DIMM3) PC133 SDR SDRAM Module X1 64MB∼1.0GBTotal System Memory (Max. 3.0GB) 3 64MB∼3.0GBNOTE! Make sure the installed memory are PC133 SDRAM support 133MHz memoryclock, otherwise the system may hang during startup.Generally, installing SDR SDRAM modules to your motherboard is very easy, youcan refer to figure 2-4 to see what a 168-Pin PC133 SDR SDRAM module lookslike.DIMM2 (BANK2+BANK3)DIMM1 (BANK0+BANK1)DIMM3 (BANK4+BANK5)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 SDR SDRAM CLOCK is set at 133MHz, use only PC133-compliant SDR Modules. When this motherboard operate at 133Mhz,most system will not even boot if non-compliant modules are used becauseof the strict timing issues, if your SDR Modules are not PC133-compliant,set the SDR SDRAM clock to 100MHz to ensure system stability.Figure 2-4
