Editing Synchronous dynamic random-access memory (section)

==== PC66 ====
'''PC66''' refers to internal removable computer [[random-access memory|memory]] standard defined by the [[Joint Electron Device Engineering Council|JEDEC]]. PC66 is Synchronous DRAM operating at a clock frequency of 66.66&nbsp;MHz, on a 64-bit bus, at a voltage of 3.3&nbsp;V. PC66 is available in 168-pin [[DIMM]] and 144-pin [[SO-DIMM]] form factors. The theoretical bandwidth is 533&nbsp;MB/s. (1&nbsp;MB/s = one million bytes per second)

This standard was used by [[Original Intel Pentium (P5 microarchitecture)|Intel Pentium]] and [[AMD K6]]-based PCs. It also features in the Beige [[Power Mac G3]], early [[iBook]]s and [[PowerBook G3]]s. It is also used in many early [[Intel Celeron]] systems with a 66&nbsp;MHz [[front-side bus|FSB]]. It was superseded by the PC100 and PC133 standards.
