3. H/W SETUP System Memory 3. HARDWARE SETUP 3.5 System Memory This motherboard uses only Dual Inline Memory Modules (DIMMs). Four DIMM sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 16, 32, 64, 128, 256, 512MB, or 1GB densities for a system memory configuration of 32MB up to 1.5GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NEC's Virtual Channel SDRAMs and Enhanced Memory System's Highspeed DRAMs. IMPORTANT (see General DIMM Notes below for more) • SDRAMs used must be compatible with the current Intel PC133 SDRAM specifications. • DO NOT attempt to mix registered SDRAMs with VCM SDRAMs. Install memory in any combination as follows: DIMM Location Socket 1 (Rows 0&1) Socket 2 (Rows 2&3) Socket 3 (Rows 4&5) Socket 4 (Rows 6&7) 168-pin DIMM Total Memory SDRAM 16, 32, 64, 128, 256, 512MB x1 SDRAM 16, 32, 64, 128, 256, 512MB x1 SDRAM 16, 32, 64, 128, 256, 512MB x1 SDRAM 16, 32, 64, 128, 256, (512MB) x1 Total System Memory (Max. 1.5GB) = 3.5.1 General DIMM Notes • DIMMs that have more than 18 chips are not supported on this motherboard. • For the system CPU bus to operate 100MHz/133MHz, use only PC100-/PC133- compliant DIMMs. • ASUS motherboards support Serial Presence Detect (SPD) DIMMs. This is the memory of choice for best performance vs. stability. • SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips. • BIOS shows SDRAM memory on bootup screen. • Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64, 128, 256, 512MB. WARNING! Make sure that the DIMM you use can handle the specified SDRAM speeds, otherwise the computer does not boot. ASUS CUV4X-E User's Manual 23
