At first only 32 GB registered then I took them out and reinserted them and 48 GB registered. I will give it another try and see what happens. MAC Sales Rocks and their products are superior so I am sure it may be something at my end.

Thank you for the feedback on our RAM. We recommend cleaning off all of the RAM sticks with a pencil eraser and gently removing the residue. Try inserting them again and see if that helps get all of them working properly. If you are still having issues double-check that the product you received is compatible with your device. Please feel free to contact us if you have any further questions, comments, or concerns. https://eshop.macsales.com/Service/
