    In addition to installing your CPU, Tyan highly recommends that you install a CPU fan/heatsink combina- tion, and if needed, additional chassis fans. To this end Tyan has provided several connectors to power the fan(s), as well as the fan pinout (shown above). Here is some information you may find useful: - We recommend you use FAN3 and FAN4 for the CPU cooling fans - All other fan connectors are left to the user’s discretion...

    Please keep in mind that although some memory modules may appear to be high-quality, they may con- tain inferior or substandard parts. The type of memory you choose to install should be checked against the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com Memory Installation Procedure Here are some details of memory installation for this board: At least one unbuffered DIMM must be installed for the system to POST.

  • Page 24: Connecting The Power Supply

    2.13 Connecting the power supply This motherboard requires an ATX power supply. Tyan recommends using one that conforms to industry standard Revision 2.01. The images below show the ATX power connector before (Figure 2.8a) and after (Figure 2.8b) it has been plugged in. The clip on the power connector should lock over the tab on the onboard connector.
