[M] Crucial Ballistix Elite 16GB 2666 DDR4 Memory Kit Review
 

The Ballistix Elite RAM kit is featuring very sturdy, rugged heatsinks and seem to drive up the module weight quite a bit. Unlike some other manufacturers, Crucial likes to equip some of their RAM series with extra sensors, in this case for tracking temperature per each module, which can be checked out in real time via their Memory Overview Display (or M.O.D.) utility.
