    Does anyone have Nvidia RTX 2080 or 2080 ti to use in bootcamped windows? does it run at pcie link speed 5.0 gt/s (PCIE 16X) ?

    Thanks!

    Hi there, I am currently running a RTX 2080ti. It does run at full speeds.
    However, you need to know that it only works if you install Win 10 in UEFI mode.
    I couldn't boot the system with Win 10 in BIOS mode.

    Edit: If you read through the bootrom thread, using Win 10 in UEFI mode can cause serious boot rom corruption which could actually brick your mac pro. This is why I wanted to go back to BIOS mode... and that's when I figured out that the 2080ti does not work in that case

    sounds good to me. I am currently using W10 in UEFI mode so that will not be a problem for me.
    is it possible for you take a screenshot of z-gpu in bootcamped windows? thanks for the reply!

    It's possible that only 138.0.0.0.0 or 140.0.0.0.0 firmware will allow full PCIe 2.0 x16 in Windows.

    I don't know. What I do know is that only after upgrading to 138, MVC GPU's would remain in PCI-E 2.0 mode AFTER waking from sleep in Win 10. Before 138, MVC GPU's where locked to 1.1 until reboot

    EDIT: At least that was true for Maxwell and Pascal GPU's from MVC

    You're welcome
    For the RTX, the only reason I could think of would be the ability to use it in BIOS mode.
    However, no one knows if there will ever be drivers for Turing in Mac OS...

    I am thinking to use my mac pro 5,1 as full blown windows machine now. which manufacturer do you currently use for your 2080ti card?

    Thanks again for the speedy reply man

    You're welcome, glad to help
    I actually bought the founders edition... Mainly because of the looks:p
    And because I never had issues with the FE cards.
    There are a lot of good brands... I'd probably go for EVGA or ASUS

    Be aware if you plan to game a lot, the mac pro's old CPU's will bottleneck the GPU in some games.

    I'll be getting a new 9900k machine and the 2080ti will go in there.
