PC66

PC66 refers to internal removable computer memory standard defined by the JEDEC. PC66 is Synchronous DRAM operating at a clock frequency of 66 MHz, on a 64-bit bus, at a voltage of 3.3 V. PC66 is available in 168 pin DIMM and 144 pin SO-DIMM form factors. This memory runs at a theoretical throughput of 533 MB/s.

This standard was used by Intel Pentium and AMD K6-based PCs. It also features in the Beige Power Mac G3, early iBooks and PowerBook G3s. It is also used in many early Intel Celeron systems with a 66 MHz FSB.

It was superseded by the PC100 and PC133 standards.
