MP 1,1-5,1 Can GTX 680 Phantom go in slot 2 of Mac Pro 3,1?

[moyanagy]

I have ordered a Gainward GTX 680 Phantom, but only after discovered it's 3 slots high. This means if it goes in slot 1, it will block slot 2. I would like to use this PCI-E SSD adaptor in my other 16x slot.

Can I put this GPU in slot 2, and use slot 1 for the adaptor, or is slot 1 needed for primary GPU?

You can use any PCIe card on slot-1.

Your GPU choice will bring you problems, it's so big that the card will block both slots 3 and 4 when installed on slot 2, you won't use a USB 3.0 card for example.

Thanks for the answer. I got a good price on the GPU, but didn't realise it was quite so big until after I ordered it. I still think it is the right choice, and SSD in slot 1 would fill all my needs.

a 2.5" SSD, a m.2 SATA SSD or single m.2 NVMe PCIe card can be used in all slots.
only a multiple m.2 NVMe PCIe card with PCI switch should be inserted in slot 2 or slot 1 for maximum performance.

note: slot 4 is the top and slot 1 at the bottom

So am I right to understand that I could put the GPU into slot 1 (at the bottom) and the PCI-E SSD adaptor into slot 4 (at the top) without performance penalty?

This Sedna card is PCIe 2.0 x1. Won't matter where you install it, all MP5,1 slots are at least PCIe 2.0 x4.

Perfect, thank you for this information. It's useful to know.
