Types of sdram
PC66 SDRAM is the original module speed of SDRAM. PC66 SDRAM was the earliest version of SDRAM and therefore came in a number of smaller megabyte sizes than later versions. Most early motherboards were rated for PC66 SDRAM. The available sizes are 32MB (megabytes), 64MB and 128MB.
PC100 SDRAM was released after PC66 SDRAM and runs at a higher speed. It has the same number of pins as the earlier memory module and is capable of utilizing the same RAM slot. The only difference when installing this SDRAM in compatible computers with older systems (PC66 slots) is that the SDRAM will run at a slower speed. PC100 RAM comes in sizes such as 32MB, 64MB, 128MB, 256MB and 512MB.
The last generation of SDRAM is PC133. The PC133 memory provided a speed upgrade and comes in larger sizes than previous generations of SDRAM. PC133 modules are backward compatible with older SDRAM slots. The PC133 memory, however, will be forced to run at the slot's slower bus speed (PC66 or PC100). The memory comes in sizes like 128MB, 256MB, 512MB and 1024MB.
