Hey there,

So you added the new ram, alongside the old 8gb stick? If this is the case then the new ram may be faulty. Is th old ram removeable, so you could take it out, and only put in the new one?

The problem is that ram from different manufacturers even if they have the same timings and voltage may not work together at all. It could also be that the new DIMM is faulty.

You need to have a 2 x 8 kit. If you own ram is soldered then you cna only add one more DIMM. Go here: Crucial System Scanner | Memory Upgrade Scanner | Crucial | Crucial.com and see what ram they recommend, and buy that one. It should then work.

Test the new ram one stick at a time in each ram slot.
