May 08, 2014, 3:18 PM — For gamers and desktop users looking to shift to the new DDR4 memory as quickly as possible, the wait will end in the third quarter this year.
Crucial expects to ship new DDR4 memory for both servers and desktops around the same time in the third quarter, said Michael Moreland, worldwide product marketing manager at Crucial.
New DDR memory is usually shipped first for servers and then for desktops, but that trend will change with DDR4, which has been under development for more than five years. PCs will be faster and more power efficient with DDR4, which provides 50 percent more memory bandwidth than DDR3 and 35 percent more power savings.
"We expect DDR4 adoption will take place -- the parts, the boards, the accessories will be there for customers," Moreland said, adding that motherboard makers have also been stepping up to add DDR4 support.
Graphically intense games and high-end server applications are bandwidth sensitive, and DDR4 memory will make computers more responsive, said Nathan Brookwood, principal analyst at Insight 64.
"As you go to more cores and higher clock frequencies, it's all about bandwidth. [DDR4] is going to be in high-end servers and high-end PCs," Brookwood said.
Crucial's DDR4 DIMM shipments will come when Intel ships chips that support the new memory. Intel has added DDR4 support to server and enthusiast desktop processors, and Crucial's DDR4 DIMMs will plug into those systems. Intel's upcoming eight- to 16-core, Haswell-based Core Extreme Edition processors and Xeon server chips code-named Grantley will be DDR4 compatible.
As with DDR2 and DDR3, it's safe to assume that initial DDR4 DIMMs could be priced at a premium, Moreland said. The memory industry is volume-sensitive and prices typically come down as adoption grows and more chips are produced. DDR4 is ultimately expected to completely replace DDR3.
Crucial is a subsidiary of Micron Technology, which will provide the basic DDR4 technology.
Crucial has shipped DDR4 modules for testing to motherboard makers and system builders. The modules include RDIMM (registered dual in-line memory module) with ECC error correction for servers, and UDIMM (unbuffered dual in-line memory module) -- which doesn't have error correction -- for desktops. Crucial is sampling 4GB, 8GB or 16GB RDIMM modules and 8GB UDIMM modules. The modules draw 1.2 volts of power.
It could take longer for DDR4 to reach laptops, Moreland said. Intel hasn't yet provided details on its next PC chip code-named Broadwell, which will succeed Haswell. Broadwell shipments have already been delayed by a few quarters.
