Different types of RAMs
Different types of RAMs
RAM : - The type of RAM doesn't matter nearly as much as how much of it you've got, but using plain old SDRAM memory today will slow you down.
There are main types of RAM: SDRAM, DDR and Rambus DRAM.
SDRAM (Synchronous DRAM): -
Almost all systems used to ship with 3.3 volt, 168-pin SDRAM DIMMs. SDRAM is not an extension of older EDO DRAM but a new type of DRAM altogether. SDRAM started out running at 66 MHz, while older fast page mode DRAM and EDO max out at 50 MHz. SDRAM is able to scale to 133 MHz (PC133) officially, and unofficially up to 180MHz or higher. As processors get faster, new generations of memory such as DDR and RDRAM are required to get proper performance.
