The fastest signals likely to be found in most computers are 266 MHz (PC2100 DDR SDRAM, 4x AGP), or whatever the off-chip speed used with RDRAM is. That's still fast enough to be difficult to work with, however. And even faster signals are in the works; 8x AGP and DDR-II (533 MHz) are on the way by next year. -- http://www.piclist.com hint: The PICList is archived three different ways.
