I have an 2009 MB871LL/A. Do anyone know if Samsung M393B2G70AH0-YH9Q5 16GB DDR3 ECC Registered DIMMS will work? I am running Hauptwerk virtual pipe organ software and some of the sample sets require 48-64GB of real memory to load.

Is this the model build year series of Mac Pro you have? (early, mid, or late 2009)
The specifications change over various build year models, so to 'identify your computer by serial number' is also very helpful... http://www.powerbookmedic.com/identify-mac-serial.php
Then one could attempt to match RAM specification and compare products. Also, there is a page at OWC where you can cross-reference RAM, that also depends on the build model year series information.
I will ask the host to move your post to the Mac Pro (desktop computer area) because it is not a MacBook.
Good luck & happy computing! 🙂
You certainly do not want to own perfectly good DIMMs that do not happen to work in your Mac Pro. That is why I recommend you deal with a Vendor who will say:
"It works in your Mac,
or your money Back."
Crucial and OWC are often mentioned. In the US, I like this Vendor as well, but they are not selling the 16GB Registered DIMMs:
In the 2009, 2010, and 2012 models, Registered DIMMs do not play nice with unregistered DIMMs. Also, only slots 1, 2, and 3 can be filled, because slot 4 shares its channel with slot 3, and registered DIMMs do not share nicely.
Does anyone know if Samsung Registered DIMMS will work?
