"2010-2012 Mac Pro Installs
Additionally, certain PCIe install configurations are not recommended or supported. Specifically, when certain double-width GPUs are installed in the bottom x16 slot (default / recommended), and the Accelsior 4M2 is installed in the neighboring x16 slot, either the GPU's shroud or its fans can contact one or more screws (or PCBA components) on the bottom of the Accelsior 4M2, causing potential problems. For this reason the XFX RX 580 cards sold by OWC - such as OWCMP1012R580V - cannot be used in conjunction with the Accelsior 4M2 in the above-noted configuration; the Accelsior 4M2 would have to be installed in one of the x4 slots higher up the logic board, which would result in reduced SSD performance.

The following commonly used double-wide GPUs have also been sold by OWC in the past, have been tested with the Accelsior 4M2 in the above dual x16 configuration, and did not make contact with the fans or other critical card components. If each card is installed properly according to Apple's PCIe card recommendations for these Mac Pro models, these configurations should work.

- Gigabyte Radeon RX 580 Gaming 8G."
