The table below shows the ideal system timing characteristics for the various technologies discussed in this section, when run at 66 MHz. They are ideal ratings because they are the best the technology can normally support. In order to achieve these timings the chipset must be optimized to deliver them. Older chipsets will require slower timing. For example, 5-1-1-1 SDRAM timing is possible using Intel's 430TX chipset, but the older 430VX only delivers 7-1-1-1 timing with SDRAM.
