    Okay, so I recently purchased a 2010 Mac Pro after researching them for about 9 months, and was excited to have a speedy machine after my 2011 iMac's video card took another crap.
    I bought a fairly maxed out tower off of ebay, it arrived working great, but after about 2 weeks it took a crap in the middle of doing a photoshop action.
    The machine still booted off of the 2.5 with windows on it, so I figured it was the ssd with mac os on it. After reading quite a bit, I acquired an SM951 AHCI and pcie adapter. The seller said he'd installed High Sierra like I asked, but when I installed it I got nothing. I found it using target disk mode with my old MBP, and noticed it had a time machine back up file, with 2 folders... so I copied them over to my MBP, and then installed and booted successfully from Sierra (had it on USB already), but when trying to then install High Sierra, it wouldn't let me choose the drive as it said it didn't have the right firmware. I cantc really find much on making this work, so any help is greatly appreciated.
    Also, what OS and drivers do I need to run my flashed Titan X (maxwell)? I have a stock gt120 in it to reformat and install OSX.
    Thanks in advance!!

    If the TitanX is flashed, there is no need to install the GT120. In fact, may make things more complicated.

    I am quite confused what you really want to achieve. Install 10.13.6 on the PCIe SSD?

    If you already has a working 10.13.6, all you need to do is just download Carbon Copy Cloner, and clone your existing boot drive to the PCIe SSD. You can utilise the free trial period.

    If you want to make a clean installation, then you may need to update the firmware, the instruction should be on the screen, just do exactly per the instruction says.

    Anyway, please read this.

    After step 7, you may continue to install High Sierra. Do NOT go Mojave, there is no driver for your TitanX.

    Thank you for the link, I'll check it out and let you know if it helps!

    High Sierra was on the existing boot drive that failed, and I want to keep using that OS as it seemed pretty stable... should I be using a newer?

    NO, you should stay at High Sierra. No newer macOS work for your TitanX.
