3. HARDWARE SETUP 3.6 Central Processing Unit (CPU) The motherboard provides a ZIF Socket 478, for CPU installation. A fan and heatsink should be attached to the CPU to prevent overheating. Purchase and install a fan and heatsink before turning on the system. Gold Arrow 3. H/W SETUP CPU P4T-E P4T-E Socket 478 1. Locate the Socket 478 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees). 2. Insert the CPU with the correct orientation. The gold arrow of the CPU must be oriented toward the inner corner of the socket base nearest to the hinge of the lever handle. Gold Arrow 90 - 100 CAUTION! The CPU fits in one orientation and should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins. 3. Once completely inserted, press the CPU firmly and close the socket lever until it snaps into its locked position. 4. Install an Intel fan heatsink. CAUTION! Take care not to scrape the motherboard surface when mounting a clamp-style processor fan, or else damage may occur. When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or else damage may occur! Refer to heatsink/CPU documentation. NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your Socket 478 processor or else boot-up may not be possible. Socket 478 processors provide internal thermal sensing: a socket mounted thermal resistor is not needed. ASUS P4T-E User's Manual 25
