Apple AMD Radeon MPX Modules

Apple currently has four different Mac Pro Expansion (MPX) Modules that contain AMD Radeon Pro graphics processing units (GPUs). Radeon Pro MPX Modules can use slots 1-2 and slots 3-4, and you can install one or two of each module:

Radeon Pro 580X MPX Module: one module only
Radeon Pro W5700X MPX Module: one or two modules
Radeon Pro W5500X MPX Module: one or two modules
Radeon Pro Vega II MPX Module: one or two modules
Radeon Pro Vega II Duo MPX Module: one or two modules

You can use Radeon MPX Modules along with other third-party PCIe graphics cards. If you use Boot Camp, using a Radeon MPX Module and a third-party AMD graphics card isn't supported when your Mac is using Windows. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).

Apple I/O card

Mac Pro comes with the Apple I/O card, which has two Thunderbolt 3 ports, two USB-A ports, and a 3.5mm headphone jack. The Apple I/O card comes preinstalled in slot 8 and can't be installed in another slot.

Historically, the Mac OS used a form of memory management that has fallen out of favour in modern systems. Criticism of this approach was one of the key areas addressed by the change to Mac OS X. The original problem for the designers of the Macintosh was how to make optimum use of the 128 kB of RAM that the machine was equipped with. Memory Monitor is a little Mac OS X application that displays the memory usage in its Dock icon (and optionally in a floating window), like CPU Monitor displays the CPU usage. Let't keep this thread to be focused on OS X memory management from versions 10.0 through 10.8 Mountain Lion. The 10.9 release 'Mavericks' has substantially changed memory management by adding compressed memory and additional classes of memory pages and probably deserves it's own question. – bmike ♦ Oct 24 '13 at 18:39.

This app monitors and displays current memory consumption right at your system status bar. FreeMemory for Mac is a utility to free up unneeded memory in your Mac OS X device. It is available for free from the App Store and download sites.

Third-party PCIe cards

You can install many different PCIe cards in your Mac Pro, such as fibre channel cards, fibre networking cards, and pro video and audio interface cards. The PCIe bus on your Mac Pro provides up to 300W auxillary power. If your PCIe card requires additional power, such as a GPU, use the Belkin Aux Power Cable.

Mac Pro supports the same GPUs that are supported by external graphics processors (eGPUs). If you use Boot Camp and want to install a NVIDIA card to use in Windows on your Mac, don't install the card in slot 2. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).

Some older PCI cards might use 32-bit Option ROMs that aren't compatible with your Mac Pro. If you install a PCI card that uses 32-bit option ROMs, your Mac Pro might not start up correctly.

Remove Apple Raid Card For Mac Pro

Not sure what to do next, please help. I have recently bought a mac pro which did not come with a Mac Pro RAID card. I was able to obtain a RAID card from Apple but it did not come with install instructions.
I have spent hours with AppleCare support but none of them was able to help me because since the card is so new. I brought it to an Apple store and they told me that the card was missing some cables and they told me that there wasn't anything they could do for me.
This is the only RAID out there which can boot into the OS X which is why I went out of my way to get it from Apple. Apparently, the installation of this RAID card is more involved than just simply plugging it into one the available PCI slots. I am trying to take advantage of the hardware RAID speed (namely RAID 5) so I don't have to worry about backing up my data manually.
If anyone has any ideas or instructions on how to install this card I would be so grateful. Thank you so much in advance.
