Although Corsair does not directly specify ECC or Non-ECC, they do provide us some insight:
Vengeance memory supports the Intel XMP (Extreme Memory Profile) standard, and each module is individually factory-programmed with an XMP profile indicating supported timing, frequency and voltages. Just enable XMP on your compatible motherboard and you'll automatically get optimized memory overclocking without having to deal with multiple BIOS settings. Of course, if you're an experienced overclocker — or an aspiring one — you can adjust the settings to push for even higher performance.
