Can I use ram memory with the following specifications PC3L-12800L 204-pin DDR3 11-11-B2, 8 GB ( 4GB modules) on a Mac mini late 2012 without harm or reduce the life of the mac since this type of memory works in a different voltage, if not mistaken 1.5

Yes if the manufacturer specifically states it will work with your model Mac and you can return it if it does not work. Macs are picky about memory

Who is the manufacturer? If it is PNY, avoid at all costs. PNY RAM

was nothing but problems with my late 2013 27" iMac even though it was

stated to be "Mac Compatible".n Replaced with RAM from OWC and has

run silky smooth ever since.

Strongly suggest getting RAM from OWC or Crucial's Mac Specific RAM. I personally

have had really good luck with Mac Specific RAM from Corsair.

Those are the same as what goes in a 2012 Mac Mini, so they should work fine.
