    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, that’s 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.

    40% More Energy Efficient
    Get better performance – using less power. Operating at just 1.2V compared to 1.5V for standard DDR3 memory, Crucial DDR4 consumes 20% less voltage than standard DDR3 technology. Crucial DDR4 modules also contain other efficiency features, for an overall power reduction of up to 40%.

    Not compatible with Samsung DDR4

    Comments about Crucial 16GB DDR4-2400 UDIMM:

    Purchased one 16GB stick to install with in my Dell 8576 with one 8GB DDR4 stick. Used the Crucial Analyzer tool to recommend choices and chose this one. Installation went smooth, BIOS recognized both sticks for a total of 24GB (max is 32GB) and everything booted fine. After the first restart, desktop would not boot. Removed new memory and desktop would boot and restart without issue at 8GB. Now, I tested the 16GB Crucial stick and IT booted great and held during any restart. Updated to most recent BIOS and installed both together again, boots fine first time and second time will not boot together. Separately they both boot fine. No instead of a 24GB machine I can only use the larger Crucial 16GB. Expensive to only gain 8GB by not being compatible with Samsung.

    Comments about Crucial 16GB DDR4-2400 UDIMM:

    I already had 2-4gb modules and had two open slots in my desktop. Ran the Crucial Compatibility Program and selected the 16gb module. Good price, and easy to install. I now have 24gb of memory and Windows is running great. Total upgrade time less than 5 minutes. Very satisfied! I love the program that identifies compatible products!
