In the case that it doesn't fit because if it did fit it still wouldn't work then I'm not going to try and make it fit. Yeah so must be an error on Crucial's part. I guess I can contact them to correct it.Do they even fit in physically?
I believe it must be a mistake in their configurator.
Thanks that makes sense.Must be some kind of mistake as DDR4 is not pin-compatible with DDR3. That RAM will work in an iMac Pro, but it will not work in a 2013 Mac Pro.
