Crucial Ballistix Elite DDR4-2666 MHz 4x 4 GB @ techPowerUp
 

Crucial's latest has spent some time being punished in my memory testing rig, stretched to the limits and back again. Before giving it a chance to rest, I put Crucial's Ballistix Elite DDR4 through the paces. With a big black heatsink, this kit not only looks mean; Crucial's Ballistix Elite DDR4 packs a good punch, too!
