After seeing all the literature on how it's possible to upgrade from 4GB to 16 for a mid-2010 MacBook Pro, and going a bit of research, I went ahead and purchased this:

Crucial 16GB Kit (8GBx2) DDR3 1600 MHz (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Notebook Memory for Mac CT2C8G3S160BM

...but it's not working. I either get a black screen with no response, or a black screen with the three beeps.

I don't think I have the wrong RAM. I've looked through countless MacRumors and Apple forum posts for an answer, so I'm not just being lazy and posting here.

I've installed and re-installed multiple times, switching the slots time and again. Also, just using one stick of 8GB isn't working either.

How is it wrong? The OP is using 1067MHz RAM.

1066 / 1067MHz RAM is really 1066.66(repeating)MHz (i.e. 1066 2/3MHz)
RAM. Some people just drop the decimals when describing it. Others round it up.
No, read his first post. He bought 1600MHz RAM. No matter what speed RAM you put in the 2010 MBP, it runs at 1066/1067 so this won't be reflected in "About this Mac."
