S UPER P3TDDR User’s Manual 2-2 Processor Installation ! When handling the processor package, avoid placing direct pressure on the label area of the fan. The following pages cover the installation procedures. You should install the processor in the motherboard first, then install the motherboard in the chassis, then the memory and add-on cards, and finally the cables and drivers. Following the installation procedures in the order they appear in this chapter should eliminate the most common problems encountered when building a system. IMPORTANT: Always connect the power cord last, and always re- move it before adding, removing or changing any hardware compo- nents.
Processor You are now ready to install the processors. Your P3TDDR motherboard has two 370-pin, FCPGA type sockets that support single or dual 370-pin Pentium III FCPGA (not SEPP) 500 MHz - 1.26+ GHz processors (including low power Pentium III processors) at Front Side Bus speeds of 100 and 133 MHz. Lift the lever on the FCPGA socket and install with the notched corner of the processor oriented with pin 1. Fully seat the processor into the socket and then close the lever. See Figure 2-1 for views of the FCPGA 370-pin socket before and after processor installation. Heatsink Follow the instructions that came with your processors and heatsinks to attach heatsinks to the processors.
Each of your heatsinks should have a 3-pin fan connector, which should be connected to the CPU FAN header. Make sure that good contact is made between the processors and the heatsinks. Insufficient contact, incorrect types of heatsinks, fans, or ther- mal compound used or improper amount of thermal compound applied on the CPU die can cause a processor to overheat, which may crash the system. 2-2
