We knew it was coming, and here it is. Corsair has announced two families of high-performance DDR4 memory for desktops: the Vengeance LPX and Dominator Platinum. Both are aimed at Intel's upcoming Haswell-E processors and matching X99 motherboards, and Corsair is showing them off in a dizzying video backed by what sounds suspiciously like dubstep:
These DIMMs have speed ratings of 2666MHz, 2800MHz, and 3000MHz, and they all sip only 1.2V. (That's DDR4 for ya.) Initially, Corsair will offer 4GB and 8GB modules in addition to 8GB, 16GB, 32GB, and 64GB kits. "By 2015," though, the company says we can expect 16GB modules, which will pave the way for 128GB kits.
What else? The modules have XMP 2.0 profiles, are validated to work with motherboards from a variety of vendors (Asus, ASRock, EVGA, Gigabyte, and MSI), and feature "user-swappable colored 'light pipes' for customizable downwash lighting." Also, thanks to Corsair Link, you can monitor DIMM temperatures in real time.
Look for these bad boys in stores at "the end of August"—but don't try to stick them in a non-Haswell-E system. They'll only fit in 288-pin DDR4 DIMM slots.
