Hmm thats a bit scary info, seems the micron is the "cheaper/less doable" version, and afraid of the long vitality for the cards with these vs samsungs.
Gotta be a reason to why they change, scary with the samsung parts seems more stable / less hot. Its alot of money if its dies early / after warranty, cause we are early adopters.
Could also be the reason why its so hard to get cards, the orders get mowed time after time, my order went from, 13/11 - 18/12 - 15/1 2019....perhaps they are aware and stopped production with micron chips.
I fear they will jyst change the never cards to samsung ram, and rma those micron chips that dies early, even though they know the failrate is high. Sucks to pay a premium with less quality components, and perhaps components that "burns out" faster.
A thought i had regarding the dying cards, seems to come true. Will be interesting the next couple of weeks, how it will unfold.
