Yes if you added RAM, it needed to be match up with the currently installed RAM at a minimum Same Voltage and Timings. if all 4 sticks are matched up. you'll need to try resetting them hoping that will solve the problem. With that failing remove all but 1 stick and insure It works in all for slots. do the same with the other 3 until you find the defected Ram stick or slot. If you only put the 2 stick in that you can get to, then try them one at a time to see if you can determine the defective stick.

So your good news first.
Both sticks of ram run at 1.5v (the voltage the ram runs at)
Both sticks of ram are CL11 (The time it takes between a command having been sent to the memory and when it begins to reply to it.)
Now the bad news,
The ram looks like it has different timings.
For the stock Elpida ram
EBJ40UG8BBU0-GN-F 1600 DDR3-1600K (11-11-11) This doesn't list the tRAS (could be 24 or 27)
And your replacement ram has timings of (9-9-9-24)
Usually the lower the numbers the better (because it's measured by the time it takes to process or the delay). If these timings I found are correct then you should be able to run just the new ram in your machine with no issues. When you add your other stick of ram the computer becomes unstable due to a timing mismatch.
The computer could be downclocking the stock ram to 1333 to run at 9-9-9, and this could be causing your issue as well.
Either way, run the two PNY sticks and test.
You can test with Hirens boot cd
Link here
Either burn to cd, or make a bootable usb drive with rufus.
Memtest86+ will be on the main menu.
Run Memtest86+ for an hour, if there are any errors test one stick of ram at a time.
Let me know if you have any other questions.
