Hammerschmidt, Christoph (2007-08-29). "Non-volatile memory is the secret star at JEDEC meeting". EE Times . Retrieved 2011-04-28. The primary advantages of DDR4 over its predecessor, DDR3, include higher module density and lower voltage requirements, coupled with higher data rate transfer speeds. The DDR4 standard allows for DIMMs of up to 64 GB in capacity, compared to DDR3's maximum of 16GB per DIMM. [1] [8] [ failed verification]

In the longer term, experts speculate that non-volatile RAM types like PCM ( phase-change memory), RRAM ( resistive random-access memory), or MRAM ( magnetoresistive random-access memory) could replace DDR4 SDRAM and its successors. [69]There are two essential things to consider if you want to run memory faster than the official specification for your processor. For starters, the quality of your processor's IMC (integrated memory controller) determines if it can handle high-speed memory. Unfortunately, since no two processors are equal, and you can't judge a chip's IMC until you test it, you're at the mercy of the silicon lottery. Builders who put a premium on aesthetics face a tough choice between the best-looking and best-performance parts. Corsair brings a bit of both in its Vengeance RGB DDR4-3200 kit, providing four 8GB DIMMs (32GB total) at CAS 16 timings for a price that’s reasonably moderate given the recent market trends. And this kit isn’t all about looks; it has the goods where benchmarks are concerned, too.

Intel's 2014 Haswell roadmap, revealed the company's first use of DDR4 SDRAM in Haswell-EP processors. [44] Standards body JEDEC began working on a successor to DDR3 around 2005, [16] about 2 years before the launch of DDR3 in 2007. [17] [18] The high-level architecture of DDR4 was planned for completion in 2008.
