Mine is Micron as well.
My core is at 0+ currently, and memory to 900+. I only noticed crashes while doing certain CPU intensive tasks on my Rig, and MSI Afterburner is also freezing a lot. But that's when running 6 cards. Running 2 when I started mining had no problems with Max mem OC and 250+ to core. So yeah I suppose for my next rig I'll be careful to grab GPUs with samsung mem. Since RX 580 8G costs freakin 450$$ here, I'll just grab another 6x 1050ti or 1060 If they are somewhat normally priced it's still better to just get 1050ti and have 1/2 MH/s of the RX 580 which costs 3x more.

EDIT: 450$ for 1060???
what. I'm getting another 1050ti rig then, will post when It arrives

EDIT2: I can confirm that GTX 1050ti Gaming from MSI has Samsung memory, and it's only around 190$. They also have a 6 pin power connector, must be a better overclocker than my Asus card. So I'll grab em see how they OC. I also might start selling my Asus 1050ti as soon as one pays itself off to replace it with the 1060 or 1070 or something depending on how the prices will be in a month or so
