Memory for late 2009 Mac pro

Don't need ECC if your Mac Pro supports non-ECC. But I'm fairly certain that the 2009 Mac Pro requires ECC memory (Just like the 2008 Mac Pro).

Nice! Then you should be fine 
Apple tech docs only mention ECC.
I think it would be worth running a memory test overnight to see if any errors pop up.
Also it's astounding to see ECC Memory mix with non ECC memory.

Using NON-ECC + ECC memory with an ECC system will disable the error-checking and correcting ability on rest of your memory modules. While your system may still operate fine, the features of the ECC modules will no longer be active in your computer.
I ask then, what is the point of using a workstation with Xeon chip like Mac Pro ?

Yeah, you should remove the non-ECC module. Sell it if you don't have another use for it. Then use the money to buy a matching DIMM (same maker and same spec is best if you can).
Also you will run into troubles like that. You must install memory in pairs for your machine.
If it were me I would ditch all of that RAM and buy four 4GB ECC DIMMs. That should be about $150 ~ $175 (±)

Amazon are selling Crucial 4GB ECC (CT51272BA1067) sticks for £24.94 - I just bought the last one and have 3 more on order. Estimated delivery time is 2 weeks though.
Don't get me wrong, am not accusing you, calling names or anything
You must know what are differences, pros and cons of machine that you are buying.
For Mac Pro they are: OS X, stability (one of reasons is using ECC), speed, built quality, beauty, excellent cooling and it has every type of connectivity that i require.

ECC is important for data integrity and 24/7 stability, but not so much in a creative workstation. As 16GB of ECC is going to be £115 I'd stick with what you have bought if you are using it for image, video or audio work.
i have installed 1 of the 4GB stick and it says ok
So just out of curiosity is the single unpaired 4GB module still installed? If so how much and what have you been using your mac for mostly? Any crashes or problems?
Just curious.

i now have 2 4GB sticks installed and i've had 0 problems. I use the Mac for Final Cut, Garageband and iPhoto
Ah, you added a second stick to match it? Ya, there should be no problems with that then. Your screenshot above shows a single 4GB stick which is what i was asking about.
