Q: My motherboard is P4i45D+ and I used FSB 800 CPU with ASUS V9520MAGIC/T/64 (or PIXELVIEW GF4-TI4200-8X-NVG28A/64M) VGA card. When I play 3D games, the appearance is lag. Why?(5/15/2004) A: It is running at over-clocking mode when using a P4 with front side bus 800 MHz CPU on P4i45D+. Thus, when playing 3D games or running 3D applications, it may not be so smooth. This is normal, and it will not affect other functions.
