  • Page 21 Installation EP-BX5C The EP-BX5C supports (4) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized DRAM). • We recommend not mixing SDRAM DIMM and EDO DIMM together. • EDO DIMM can only be used with the 66MHz FSB.
  • Page 22 Installation EP-BX5C Figure 3 displays the notch marks and what they should look like on your DIMM memory module. DIMMs have 168-pins and two notches that will match with the onboard DIMM socket. DIMM modules are installed by placing the chip firmly into the socket at a 90 degree angle and pressing straight down (figure 4) until it fits tightly into the DIMM socket (figure 5).

Using the Soft- Off by Pwr-BTTN feature, you can choose either Instant Off (turns system off immediatly), or 4 sec delay (you need to hold the button down for 4 seconds before the system turns off). When the system is in 4 sec delay mode, there is a special feature to make the system to go into suspend mode when the button is pressed momentarily.)
  • Page 27 Installation EP-BX5C On the basis of bounded functions in I/O chipset, the two serial ports are able to support the External Modem Ring-in Power ON function. Once users connect the external modem to COM1 or COM2, the mainboard allows users to turn on their system through the remote and host's dial-up control.
  • Page 28 Installation EP-BX5C Notes: 1. Intel ATX version 2.0 specification has recommended you use the power supply with 0.72A(720mA) in 5.0VSB. With our mainboard, the 5.0VSB standby power only has to be > = 0.1A (100mA) then you can enjoy this unique benefit.
