More speed. More bandwidth. More efficient.

The future of memory is here.

In the ever-changing world of technology, any component more than half a decade old is usually in need of an update. At seven years old and counting, thats exactly the state DDR3 memory is in: computers can only do so much with it.

Since the introduction of DDR3 memory technology in 2007, processors have doubled in capability, SSDs have revolutionized throughput, and graphics cards have drastically increased frame rates, leaving memory as a limiting factor. With Crucial DDR4 Desktop Memory, crush the DDR3 memory bottleneck and unlock a new standard of performance.

2x the Speed

Load applications faster and run demanding programs without lag. Crucial DDR4 memory debuts at 2133 MT/s more than 30% faster than DDR3 memory technology.1 Even better, as DDR4 technology matures, speeds are projected to hit 3200 MT/s twice what was possible on standard DDR3 memory.

2x the Bandwidth

Effortlessly multitask between apps, and empower your system to fire on all cylinders. Crucial DDR4 increases memory bandwidth by over 30%, allowing your system to handle more data at once. As DDR4 technology matures, bandwidths are expected to achieve up to 25.6 GB/s twice that of standard DDR3. To maximize bandwidth, Crucial DDR4 memory is optimized for next-gen platforms that support four channel memory.
