For the system CPU bus to operate MHz/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.
CUV4X-D 60 Pins 20 Pins ® CUV4X-D 168-Pin DIMM Sockets Lock The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type, check the notches on the DIMMs (see the figure below). The notches on the DIMM shifts between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the motherboard.
