Hi,
I want to get more ram in my system. I don't think 4 gb is enough. I would like 16GB.

I found this, and it seems to match the specs that my mac needs. I messaged the seller and he claims that it is fully buffered and ECC. The only thing is that it isn't specified for mac. I have read conflicting things on this topic. Does anyone know if it will work?
Mac Pro, OS X 10.11
The answer of mine you quoted is correct.
You asked if you could use RAM meant for a PC. That can only be interpreted as RAM for a PC (99.999% of people would assume PC means a Windows computer) is somehow different from RAM made for a Mac. It isn't. All RAM performs the same basic function.
What is different is getting RAM that is designed for your computer's hardware. It doesn't matter what OS it's running, the RAM has to be the correct specification for the system board it's going to be in.
You can often get different RAM and as long as the specs are close enough, it will still work. Such as if you purchase RAM that is faster than the system board's specs. It will work, but will only run as fast as the board is designed for.
You can't do this with a 3,1 Mac. It needs those heat sinks. RAM that has specs that would otherwise work, but doesn't have the sinks will overheat.

Those don't even count as heat SINKs -- those are heat SPREADERS. they have no Fins at all.
Look closely at your existing DIMMs and the spacing between the slots. Apple expects you to FILL the space between slots with heat sinks with big fins.
Yes, that's the correct design. I have no experience with that brand of RAM, but it does say it's designed for a 3,1 Mac Pro and has all positive reviews on that item. The seller themselves have a 100% positive rating on just under 14,000 transactions where the seller (or they as they buyer) left a review.
Macs need VERY large heat sinks and a Mac-qualified temperature sensor on each DIMM, or the chassis fans will run on Maximum, which is really loud.
You've already asked this question, and it has been answered.

Please stop asking about RAM that is not designed for your Mac. I get that you're trying to find a cheaper alternative, but you need to purchase the correct RAM.
yeah ok. I'm just getting different messages. You said, and I quote, "RAM is RAM. There isn't such a thing as PC RAM vs. Mac RAM. What matters is having the correct type." But now you're saying that I need to purchase "the correct RAM," even though it is "the correct type." I'll stop asking, just give me a consistent answer please.
Ok thanks. I just want to point out that those heat sinks on the ram look pretty big.
