Okay, as my final goal is to get an Amfeltec card with 4 nvme blades in raid0 I will simply bite the bullet and see the ssd‘s as external ones in the finder, right?
So, should i keep TRIM enabled for HyperX or not? Does trim reduce write-read speeds?
Hey everyone! Just resurrecting this thread. Was there ever a solution to the this PCIE bootcamp issue?I have the exact same issue on a cMP 4,1 flashed to 5,1. Once the HyperX was installed I was no longer able to boot from a windows 10 partition installed on a separate ssd in one of the standard drive bays. I also receive the no bootable device error once windows tries to load. The only way I can boot from the windows partition is to pull the hyperx predator from the machine. I do not have the custom kext installed.
I have never been able to resolve this issue and have been contemplating pulling the hyperx permanently so I can restore access to my windows partition.
If you come up with a solution for this I would love to hear about it. You are the first person that I have seen mention this issue so I am wondering what is unique about our setups. My hyperx was purchased about 6-12 months ago.
Revising my post with good news. I managed to get Windows 8.1 installed on a the HyperX (240GB) on the Mac Pro 5,1, so I can confirm the HyperX cards are go if you want to run windows faster than SATA II on a 3,1 - 5,1I'm late to the party as usual, but I can also confirm that using the HyperX Predator, Windows is not bootable on a Mac Pro 5,1. It is however bootable on a 3,1. So there you have it. If you want fast drive access on a 3,1, the HyperX predator cards are fantastic. I have two of the 240GB versions with Capitan and Windows 8.1. Of course, the problem with this on a 3,1 is that you need bootscreen to select Windows (8,8.1) to boot. So you therefore need a GPU that can do that. The original 2600xt will do in a spare slot if you don't have a compatible GPU, but uh, the little fan sounds horrible, always has. Little fans on GPUs etc are the worst with their whine. But if you don't have a GTX680 or similar, that's what you've got to do.
Anyway, I'm putting forward what I think the ideal/functional solutions for these series of Mac Pros without going down the OpenCore route - sticking with stock standard hardware and software while being able to boot both MacOS and Windows.
For the 3,1 - the HyperX predator cards are great and can boot MacOS and Windows.
For the 5,1 - The HyperX predator cards can't boot Windows, not only that, if you have Windows installed on a standard drive and you have MacOS installed on a HyperX, Windows won't boot. You just can't have any HyperX card in the machine if you want to boot Windows (without OpenCore).
As far as the GPUs go, El Capitan puts substantial limits on what the 3,1 can drive without modification. It seems the GTX980 is the best choice.
That the 5,1 can run Mojave of course doesn't mean you should. Nvidia cards with the exception of a few older cards can't run on Mojave. So it seems that if you want to stick with Nvidia cards, you can stick with High Sierra.

This ties back to the original point regarding M.2 drives for the respective Mac Pro series, given that you can't use the HyperX if you want to use Windows on a 5,1. Luckily, if you want to stick with a GTX 980, people have reported nvme working on High Sierra on a 5,1. I can confirm nvme works on a Hackintosh running High Sierra. While I can't personally confirm, people seem to have Windows booting from M.2 on 5,1s, so I've ordered a KryoM.2 evo and a Samsung 960 evo which seem to be a safe bet.
One of the many advantages of using the 5,1 vs the 3,1 to boot Windows 8,8.1 is that you can use the Startup Disk panel to set the boot volume, so the boot screen isn't needed for normal operation.

A final note on the HyperX, I did have some trouble installing and running Windows as I think the HyperX won't hold MBR. As a mac user, I wasn't familiar with the whole MBR thing, so I didn't understand why I couldn't boot when I pulled out the HDD it was originally paired with or why Clover on a USB made it boot as a workaround. I finally figured this out when I moved the HyperX card from an old SuperMicro X7 board to the Mac Pro 3,1, to cut a long story short, start by installing Windows 7 on a HDD or SSD and then install 8.1 onto the HyperX with Windows 7 as the boot volume.
