Introduction EP-3VCA2 EP-3VCA2 Form-Factor The EP-3VCA2 is designed with ATX form factor - the new industry standard of chassis. ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards. ATX defines a double height aperture to the rear of the chassis which can be used to ho

EP-3VCA2 Installation Section 3-3 System Memory Configuration Memory Layout The EP-3VCA2 supports (3) PC133 168-pin DIMMs (Dual In-line Memory Module). The DIMMs is for SDRAM (Synchronized DRAM). DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or 125MHz (8ns) bus speed. If you use both 50ns and 60ns memory you must configure your BIOS to read 60ns. When using Synchronous DRAM we recommend using the 4 clock variety over the 2 clock. Figure 6 and Table 1 show several possible memory configura
