The 240-pin memory is a replacement for the 184-pin DDR format. It increases memory capacity from a maximum of 1Gbyte on DDR1 to 4Gbytes per memory module. The new memory chip will dramatically reduce power consumption, according to Intel.
Alan Priestly, strategic marketing manager at Intel, said applications can run faster depending on how much memory is installed, but that too much memory can cause PCs to overheat. PC manufacturers must find a way to cool down memory, which is where DDR2 has a role to play.
Marco Biermann, technical research engineer at Kingston Technology, estimated that DDR2 would use 60% less power than DDR, resulting in cooler PCs.
Dell, Hewlett-Packard and IBM said they will offer PCs based on the new Intel design and will be supporting DDR2 memory.
Dell introduced two Dimension PCs and one XPS PC based on the Intel chipset. The Dimension 8400 costs £754 with Intel's new Pentium 4 550 processor at 3.4GHz, 512Mbytes of DDR2 memory at 400MHz, and an 80Gbyte hard drive.
