What happened?
I've never had a problem with Crucial RAM myself although their SSD's have not been as reliable.
I've actually used more G.Skill then any other brand and have only had one failure.
Nothing dramatic, just a bunch of shit ram, and an rma would get you more shit ram in return. Aside from rare cases, companies get one chance to sell me stuff. If that doesn't work out, they won't be considered again. Crucial, LG, and GM are blacklisted. Husqvarna's on shaky ground. I'm especially peeved at Crucial cause I used some in a machine I built for someone else, it died soon after mine did, and I had to make a warranty repair. I built that machine to be best in class and relied on Crucial's reputation. *The ram dying affected my reputation, and ate into my bottom line.
*Not like I'm anybody, and I'm sure the person didn't care cause I fixed it, but still... If I say I'm giving you the best, it should be the best, and dying isn't the best.
