Really? No one on the Intel site knows this information about an Intel chipset???
I also contacted the Intel support mail and no answer there yet either?
Please note that based on an agreement between Intel® and Apple, all the information, support and warranty will be provided by apple directly.
At this point, I am afraid that you will need to contact Apple for further information. You can contact them with the below information:
Thank you for your reply.
OK, well, just skip the whole MacPro implementation thing. Does the 5000X MCH support quad rank DIMMs in any system?
Please note that the support that is provided through the Forum page is for desktop computer only.
It is important to mention that the chipset limitations are set by the system manufacturer. In this case, I suggest you contacting the system manufacturer to get the specifications for the chipset.
