I'm planning on upgrading my computer but I wanted to now that if I purchase a p4 800 fsb but use dual channel 533 ram will it run at 800Mhz. I just want to know because in the future I will upgrade to a duo-core that runs at 1066FSB, and I know the dual-channel 533 will run at 1066 Mhz. Otherwise I'm just going to get ddr2-800.
