Most computer technologies only last a short time before they are replaced by something new, but DDR RAM is one of the few that tends to last a while before being replaced. The original DDR SDRAM was launched in 2000 and lasted three years before being replaced in 2003 by DDR2 SDRAM.<\/p>\n

DDR2 lasted another four years before being replaced in 2007 with DDR3 SDRAM. Since then, it has been seven years without a new revision of DDR RAM, but DDR4 has finally been launched to replace DDR3 SDRAM.<\/p>\n

\"\"<\/p>\n

What’s new in DDR4?<\/h3>\n

From a physical standpoint, DDR4 is the same width as DDR3, but is slightly taller by about .9mm. The main physical difference between DDR3 and DDR4 is that DDR4 uses 288 pins compared to the 240 pins on DDR3 and the key is in a different location.<\/p>\n

In addition, the pins on DDR4 are not in a straight line but slightly curved with the middle sticking out further than the pins on the end.<\/p>\n

Though there are ton of changes, the four major improvements of DDR4 SDRAM can be summed up in lower operating voltage, increased power saving enhancements, increased frequency, and improved chip density.<\/p>\n

DDR3 RAM natively runs at 1.5V with low power modules running at 1.35V. Some manufacturers go outside of this, of course, but the majority of DDR3 RAM runs at this voltage. DDR4, however, natively runs at 1.2V with low power modules expected to run at just 1.05V. In addition, DDR4 supports a number of power saving enhancements including a new deep power-down mode to reduce power consumption when the system is in standby.<\/p>\n

The lower operating voltage and power enhancements allows DDR4 RAM to draw less power (and consequently run cooler) than DDR3 RAM.<\/p>\n

In terms of performance, DDR4 RAM will start at 2133MHz (which is roughly the upper limit for DDR3) and is expected to eventually reach speeds as high as 3200MHz. DDR4 chips are also able to be manufactured in densities of up to 16Gb (or 2GB) per chip, which is double the density of DDR3. This means that we should start seeing consumer-grade DDR4 RAM in capacities of 16GB per stick and possibly as large as 64GB per stick for server-grade memory.<\/p>\n
