PC133

PC133 is a computer memory standard defined by the JEDEC. PC133 refers to SDR SDRAM operating at a clock frequency of 133 MHz, on a 64-bit-wide bus, at a voltage of 3.3 V. PC133 is available in 168 pin DIMM and 144 pin SO-DIMM form factors. PC133 was the fastest and final SDRAM standard ever approved by the JEDEC, and delivers a bandwidth of 1066 MB per second ([133.33 MHz * 64/8]=1066 MB/s). PC133 is backward compatible with PC100 and PC66.
