2 Hardware Setup This chapter explains how to configure the mainboardÕs hardware. After you install the mainboard, you can set jumpers, install memory on the mainboard, and make case connections. Refer to this chapter whenever you upgrade or reconfigure your system. CAUTION: Turn off power to the mainboard, system chassis, and peripheral devices before performing any work on the mainboard or system.
6 Hareware Setup JP2: Smart Detect CPU Voltage Function Auto/Manual Jumper This jumper is reserved for few old non-Intel CPUs which can not be detected correctly. If you run into problems while detecting the voltage of old non-Intel CPUs, remove this jumper to correct it. JP37: DIMM Voltage Select Jumper Most of DIMMs in the consumer market is still 3.3V and this jumper is reserved only for upgrading purpose in the near feature. If you have 5V SIMM or DIMM which matches the existing 3.
7 Hareware Setup CPU Type Configuration This section shows you how to configure your CPU step by step. Note that you need to check the CPU voltage before installation.
