Hi all,

I'm not a specialist about Mac Pro 5,1 upgrade and customisation, but I recently dived into this.
I'm a sound editor and two studios where I work and don't use these anymore gave me two Mac Pro 5,1, so I could blend them and build a system for music production, at home.
I spent days and nights on this forum and on the Defintive Guide, so thanks everyone for all the work you put into this. I almost succeed and like to think I'm almost done.

I have a system with 2x 6 Cores, 32Go of RAM and a RX 580.
I bought a Sonnet M2 4x4 PCIe card, and 4 Samsung EVO+ 500Go NVME disks. They have the 2B2QEXM7 firmware.
My system firmware is 144.0.0.0.0, and I'm typing from this computer right now, running Monterey thanks to OCLP.
I also have some SSDs and HDD on the SATA bays, and a 3.0 USB PCIe card.

I'm booting MacOS from one of the Samsung NVMEs, and made a RAID 0 with the others 3 ones to work on the fastest disk possible.

After installing some software and setting everything up, I tried to start a new song with a friend on Ableton last week. Here are the two last problems I still can't solve myself and stopped me from working :

- I encountered odd freezes several times, especially while doing some music on Ableton Live. Sometimes, opening a plug in or rendering a track, or maybe at other occasions, I don't remember everything, the computer started to have a hard time making Ableton run correctly, and then completely freezed. I tried at some point to let some time pass to see if it would come back to life, but every time this happens I'm obliged to shut down the Mac manually.
When this happen, the Mac will almost always not be able to boot again, and usually NVRAM reset will unblock the situation and help me turn on the computer again.

- The other problem I encountered is that when I started the session and wanted to save it for the first time, I tried to choose my RAID 0 NVME disk but Ableton would crash anytime I would try to save there. It can open sessions from there still.
I was obliged to save on the desktop (meaning the booting disk) to be able to save my work.


I kind of don't understand where I could look into to solve this problem. I know NVME boot is not native supported on these machines but if I understood everything correctly, my firmware is not the problem? Should I forgot this idea and just boot from a SATA SSD?

I hope somebody can help me just a bit ! Sorry for the long message !

Cheers everybody,
Alex

Remember that the mac pro 5,1 does not have AVX support. So depending on the version of Ableton Live that might cause the issues.

Thanks for you reply.
I don't really know what's AVX but it seems that it's an issue with Ableton 12, and I'm running the 11. But I'm going to read more about this.

I really don’t see how that’s supposed to help but okay. It seems I’m not at the right place to seek help.

It may be a hardware fault with your MP. Mine has lockups with Big Sur onwards and I think it may be a USB issue as the front USB ports now no longer work. The MP should be fine with any OS up to Monterey. Ventura introduced changes, which made for a less stable user experience and this got worse with Sonoma, depending upon what programs you used. As long as you have the latest firmware, native NVME boot is supported. That was one concession Apple afforded the cMP.

You may have to dig further into Ableton. It's not something I run so I can't help further but it could be making demands on your system, which is pushing it to the limits of its capabilities given its age.

It’s not clear what help you are seeking. Later versions of Ableton require AVX vector instruction set to be supported by x86 CPU or Apple Silicon. AVX instruction set not supported by Mac Pro CPU. Updating to latest macOS using OC and OCLP in order to run newer versions of software applications does not necessarily guarantee Mac Pro compatible. This information all available with the Google.

Well as I said I run Ableton 11 which doesn’t requires AVX.
And the Mac has freezed outside Ableton.

It's unclear what macOS version you are running, but open Console application and look for crash reports. These reports might help identify what is causing the freezes.

I will check this out tonight, thanks. Will this Console be able to remember past crashes or do I need to do it right after one ?

Crashes should be logged and therefore readable even days after. Sadly, on mine the freezes happen before a log is able to be captured. You will only find out when you look at the various logs in the Console app in Utilities.

So i run a 5,1 dual 3.46, 128 ram, saffire pulse rx 580 with macos Sonoma on a sata ssd with protools, uad2 pcie and 3 nvme 2tb each. its no problem. One thing that keeps bugging me from reading is, that i heard some usb pcie cards have been an issue. other than that i cant see where your going wrong, or like you say try running off sata instead of nvme
