This 1GB PC2700 Double Data Rate (DDR) memory option enables synchronous DRAM to embrace much higher performance ratings and I/O bandwidths compared to previous memory architectures. This evolutionary technology allows for the smooth transition and investment protection between the older architecture's speed ranges and the ever enlarging memory capacities of the new DDR realm. This technology transition more than doubles the memory transfer rate for the older PC133MHz bus rate and yields an effective data-transfer rate of up to 2, 666MBps. This increased transfer speed enables a new generation of higher performance, lower cost IBM eServer 325 platforms that will offer expanded communications, database, online and networking solutions.
