In this way you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the screw contact any printed circuitwrite or parts on the PCB thatare near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

Due to chipset (Intel 865P) architecture limitation, a FSB 53 3 Pentium 4 p rocessor will support DDR333 and DDR266 m em ory m odule. A FSB 400 Pentiu m 4 processor will only supp ort DDR 266 m em ory m odule. (Note 1) An FSB80 0 CPU can be su pported through overclocking in BIOS. (Note 2) When FSB800 is selected as CPU frequency, m em ory will autom atically adjust to DDR400. (Note 3) Due to standard PC architecture, a certain am ount of m em ory is reserved for system usage and the refore the actual m em ory size is less than the s tated am ount. For exam ple, 4 GB of m em ory size will instead be shown as 3.xxGB m em ory during system startup.
