Bought for a NUC D54250WYKH2, this bar is perfect. Implementation and use one can simple (plug and play) by the automatic detection system without worries. I recommend it.
No problem with that memory installed in MB Pro mid 2012 to double the capacity (replacing the original memory). Bought 2 copies, it remains cheaper than 2x4 GB kit, and works well!
This RAM is declared as functional with Intel NUC (NUC5I3RYK), but does not work correctly with ... that it should not nempĂȘche probably work well with other PCs.
