Jul 6, 2015 1:06 PM in response to goonieiamby lllaass,What size modules and where did you get them/who manufactured them?
You can mix registered and non-registered sticks
Did you retain any of the original ones?
OWC modules are 1866 for the 4, 8 and 16 GB stick and 1333 for the 32 GB sticks

Jul 6, 2015 1:29 PM in response to lllaassby goonieiam,Size : 2x8gb
These are the specs: http://www.amazon.com/gp/product/B00N9PVXJK?psc=1&redirect=true&ref_=oh_aui_deta ilpage_o02_s00
Here is my current set up:
- Slots 1&2 : Original 4gb memory
- Slots 3&4: 8gb each of the new modules.
Should I mix them? have one of the new ones mixed with one of the original ones?
Thank you!

Jul 6, 2015 1:37 PM in response to goonieiamby lllaass,Your link says "
Kingston HyperX Savage 16GB Kit (2x8GB) 1866MHz DDR3 Non-ECC CL9 DIMM XMP (HX318C9SRK2/16)
"The Mac Pros use ECC (error correction) memory. You may be able to use only non-ECC memory but mixing ECC and non-ECC causes problems.
Also remember you can't mix registered and non- registered ECC memory. 4GB and 8 GB are ECC memory are typically not registered, the Apple and OWC ones are not registered

Jul 6, 2015 1:37 PM in response to goonieiamby The hatter,This: Non-ECC
Use just the new and get more - and pull the 2x4GB
Do not mix ECC and non.

Jul 6, 2015 1:40 PM in response to The hatterby goonieiam,are ECC better than Non-ECC? would I have any problem if I get more of the Non-ECC?

Jul 6, 2015 1:43 PM in response to goonieiamby lllaass,ECC memory will correct most memory errors and thus apps will not have problems.
I defer to hatter if non-only non-ECC will work.
Apple on says ECC. See:

Jul 7, 2015 1:36 PM in response to goonieiamby Grant Bennet-Alder,DO NOT use non-ECC RAM in your Server-Class Mac Pro. Installing ANY defeats one of the best features of these Macs -- the ability to keep working across minor memory errors AND knowing that quirky problems are NOT caused by random memory errors.
If installing these modules changed the speed, these are clearly not the correct modules for your Mac Pro. Buy from a knowledgeable Vendor who can tell YOU what to Install, and warrants:
"It works in your MAC,
Or your Money BACK."
