HiI have a MSI motherboard. Originally the board was for 400FSB PIV but I intend to run a 533FSB processor. The BIOS as the option 200MHz and 266MHz RAM.As far I understand if I overclock the FSB from 100 to 133 the 200MHz memory option will be transformed in 266MHz and the 266MHz in 353MHz. Is this right?ThanksJos

Jose, shouldn't think so. The 533Mhz P4 runs at 133Mhz on the FSB, so the ram would run DDR 266 with a 1:1 CPU/Ram ratio.
