Are you sure it just wasn't a figment of your imagination? Are you sure you didn't put it in backwards? Maybe you tried to install the memory from your eMachine by mistake? Why did you try to force the DIMM into your SD card slot? Just kidding, of course.
Yes, as you are aware, there have been numerous reports of fitment problems in the 2013 iMac with Crucial RAM. And, yes, I can also confirm that the OWC modules fit and functioned perfectly.
You've said that multiple times, I think the whole picture is now appearing more clear for everyone. You apparently work for OWC and came here to make people doubt the Crucial ram since it's literally $100 cheaper for $32Gig's. Why else would you make a thread about damaging ram slots from Crucial only ram and avoid posting any pictures, unless you didn't actually install them, or damage anything. Until those pictures show up their is no reason for anyone to believe you.
Tons of videos on youtube about this ram working fine and the install being fine without any "Soft Issues" or breaking ram slots or breaking even the ram itself breaking. You either work for OWC or your destroyed you mac by installing the wrong ram, or by force. The Imac ram slots dont break on their own. Their is no way to know actually know since you didn't even post pics of the ram you supposably tried. Without damage proof the best assumption would be your association to OWC.
For anyone worried about this ram, dont be. This ram works perfectly, buy it from crucial or amazon (amazon its self not a seller on amazon). Newegg and Tigerdirect also sell this ram. If you want to pay $100 more for the OWC ram feel free to, but don't do it because your afraid of the crucial ram. Crucial ram works just fine. If their is going to be an damage it will be from user error and that can happen with what ever ram you choose.
Here are some good videos on how to replace your ram, one even shows the crucial ram and has links for you.
