We're eagerly awaiting the arrival of DDR4 memory into the mainstream market, though it's going to take some time. After all, Intel's next generation Z97 chipset still uses the DDR3 standard, though on the bright side, a transition is slowly taking place. One of the driving forces is Crucial, a subsidiary of Micron, which has begun sampling next-generation DDR4 server memory through its new Technology Enablement Program.
Crucial's DDR4 memory is designed to enable next generation enterprise environments with data rates that start at 2133 MT/s -- that's up to twice as fast as DDR3 when it was first introduced, and it's expected to get even faster as the technology matures, Crucial says. When paired with Intel Xeon processor E5-2600 v3 product family-based systems, Crucial DDR4 memory doubles memory bandwidth from 8.5GB/s to 17GB/s while using up to 20 percent less voltage than DDR3 (it operates at 1.2V compared to 1.5V). It's up to 40 percent more energy efficient than DDR3.
"Memory is one of the biggest limitations when it comes to enterprise server environments. Many memory-dependent server applications are crucial to the day-to-day operations of a business, but they require higher densities of memory and increased performance," said Michael Moreland, worldwide product marketing manager, Crucial. "Crucial DDR4 memory enables servers to perform faster and run more efficiently than ever before, reducing power and cooling expenses along the way – essential for meeting the ever-increasing workload demands of data centers."
Crucial didn't say how much its DDR4 modules cost, though it did point out that it backs its DDR4 RAM with a lifetime warranty.
