Problems with Memory modules

I have been running 16gb DDR3 1600 in my system for a few years but about a month ago my system started to crash apple replaced my mother board do due a recall or something to that nature. but not with the new mother board installed i can no longer run my 16gb chips I sent them into kingston assuming the ram had failed, they sent me a new model under their warranty and was excited to see them work. my system does not except this new ram either. just beeps I'm sure its a possibility that these chips are faulty as well but then again what are the odds???

I was running

Kingston HyperX 1600MHz DDR3 PC3-12800 Non-ECC CL9 SODIMM 1.35V Notebook Memory (KHX16LS9P1K2/16) (2X8GB)

the replacement model is

Kingston HyperX Impact Black 1600MHz DDR3L CL9 SODIMM 1.35V Laptop Memory (HX316LS9IBK2/16) (2X8GB)

anyone else having a similar issue?

Can you give us the last four digits of your serial number so we can correctly identify your system.

You said YOU had replaced the motherboard (what with)? What did you do and why would Apple replace it unless they thought it was the original board?

Something doesn't add up here. Can you take a snapshot of the About this Mac > More Info ... Overview tab which gives us the basics of your system.

I suspect they put in the wrong logic board so between the case serial number & the screen capture serial number and the specs we should be able to see if its correct.

The other possibility here which I find hard to believe that Apple wouldn't check is the systems firmware is old. Here is an Apple T/N to check and up date: About EFI and SMC firmware updates for Intel-based Mac computers. Double check to make sure its at the latest.
