8GB 1Rx8 DDR4 PC4-21300 2666MHz (288 Pin) Memory – CT8G4DFS8266

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%.
