CAUTION! 1. P4i45D motherboard may be fine tuned to support higher CPU bus frequencies at over-clocking mode. If the installed CPU runs at FSB 533MHz, it will only support DDR 266 and DDR 350. If the installed CPU runs at FSB 800MHz, it will only support DDR 400. Please refer to ASRock website (http://www.asrock.com) for details. 2.
