Is a DDR Module. DDR Modules run from 266 to 400 MT/s (million transfers per second) This module has a total capacity of 1GB. Uses ECC (Error Correcting Code), ideal when system failure must be avoided at all costs. Is also registered which makes it stable enough for server conditions. You can expect the data to transfer at a rate of 400 Mhz. PC3200 memory has a chip type of DDR4100, designed of use in systems with 200MHz. its bus speed is 8 bytes and transfer rate is 3,200MBps. It has a dual-channel transfer rate of 6,400MBps.
