I purchased two pairs from my local MC Saturday. The gold version was OOS, so I bought the silver one. They are beautiful when they light up. Using G.Skill Royal version of the software, I was able to do different pattern of the light. However, happiness was short lived. One pair only lit for about a few minutes after powering on, before I even installed the controlling software. Funny thing was, why both sticks died for no apparent reason? And both sticks are from the same package also. Doesn't matter what I did, including trying them on a different board, so I returned both pairs back to the MC. Too many variables of how things could go wrong with these RGB memory. Just gonna stick with non-RGB for now.
