The new module is faulty - contact the seller.  Neither module is ECC.  
[IMAGE]Hello, I am trying to install what I believe is the same type/speed of RAM into the 2nd slot of my Dell Inspiron 15 / 3567 to upgrade it to 16gb total. I have attached a picture of both RAM sticks.  The top is the original, and the bottom is a SODIMM I bought off ebay used.  It appears to be the exact same stick by SK hynix. Original stick - HMA81GS6AFRN8N (China) 2nd stick trying to add in - HMA81GS6MFR8N (Korea) The 9th character, according to my research, is simply a "diecast" manufacture set/date.  Is it possible I have a bad stick or is there something else I need to do to get my machine to boot up?  Thanks for your help in advance!
Inspiron 3567 2nd 8gb ram install (same stick?) - says it's incompatible?
