MP 1,1-5,1 OCLP mac 5,1 Monterey NVMe PCIe card blocking boot

[Silvix]

Hello,
I am having an issue with the booting process of Monterey through OCLP while plugging in the sonnet 4x4 pcie card.
I have a mac 5,1 , RX580 8gb, booting Monterey with OCLP 0.6.1 is just fine.
Today I wanted to install the Sonnet 4x4 silent with 4 NVMe and format the SSDs but it seems that the PCIe card (or the SSDs, I don't know) are blocking the booting process. I tried to reset the NVRAM but nothing seems to work. I tried to see if some post patches were missing on OCLP but everything is up-to-date. If I remove the card the booting is totally fine. The PCIe card is on the first 16x pcie slot and the GPU on the 2nd, had to do this way because otherwise the card is touching and blocking the GPU fans. Is there a reason why the card is blocking the booting? Is there anyone who can help? Thanks in advance

If your GPU have pre-boot configuration support, install your Mojave rescue disk and try to boot from it via the BootPicker, then you can start to investigate things like all the blades are being recognized or if the config.plist is correct and etc.

Unfortunately I am not an expert so I literally have no idea what you are talking about:/

I installed Mojave now and it still doesn't work so it is not an OpenCore problem. Could it be there is an issue with the card?

I think you need the latest firmware installed with Mojave for NVMe boot. There is also an optional Setting in the OCLP Boot Configuration for NVMe that might help.

I have the last firmare already, even because it won't boot Mojave otherwise. It has nothing to do with OpenCore that I am sure. I plugged in also the card without any drives on it and it boot the OS, as soon as put a drive on the card it doesn't. I tried to change the drives (which are all brand new and not formatted yet, maybe was one which was creating a problem), putting one at the time in different slot of the card but nothing, it won't boot. What else can I do?

Hello I have a problem with the Sonnet Pcie 4x4 silent. I have a MacPro 5.1 with updated firmware to 144.0.0.0.0, macOS Mojave, GPU Rx580. I have 4 SSDs which are compatible with thePCIe card (I called the Sonnet Support for confirmation). When I try to boot the computer with the card with SSDs on it won't boot. Originally I thought It was a PCIe slot problem, I checked it isn't since I swapped with the Gpu card and it still does not work. The GPU is working on both 16x slots. The customer support said it could be a faulty card so I returned it and today a new one arrived, but I still have the problem: the bloody computer won't boot if the card is plugged in with the SSDs. I know that the SSDs are not faulty because I tried all of them one at the time with the card and all the time it doesn't work, It cannot be that all the SSDs are faulty. I believe therefore that there is a problem with my Mac, what do you think it could be? Thank you!

Hello , I was wondering if you. found a fix for your problem ? Does monterey allow booting from Nvme from PCI ?

 

[Silvix]

Hello, I have found the issue. It was the Nvme SSDs. Those SSDs were not compatible at the end, even though both the the manufacturers (PCie card and Nvme ssd) and said they were. I changed to samsung SSDs it went fine. Monterey does allow.

thanks, So you are able to boot Monterary from NVME on PCI ! I'm going thru a similar process of upgrading my 5,1 to Monterey. Currently, I am booting my Mojave from OWC 1TB (4x250tb blades) Excellsior NVME on PCI bus . I have formated using disutility to create a raid with blade one as JBOD for MACOS, as blade 2,3,4 as raid for data
If you don't mind, I have a few questions.

1) How did you format your NVME in Disk utilityto create your boot volume? Did you use Mac External Journal with GUID.
2) Did you partition your Nvme ?
3) When using OCLP and creating your USB boot drive did you then install Monterey directly to your SSD Nvme PcIe boot volume? Or did you copy it over from another ssd boot volume?
4) Did you enable NVMe within OCLP settings tab ?
5) Was your RX580 flashed?

thanks for your help !!

1) I did not made RAID, I have 4 NVme, one for MacOS the other 3 in RAID 0.
2) NO
3) I have another MacBook. I used it to make the boot usb of Monterey with OCLP for the MacPro. Booted the flash drive , opened the Disk utility, formatted the NVMe then installed Monterey on one.
4) everything is done automatically, there is not need
5) nope

One question Sylvix - What NVMe SSDs did NOT work? I'm about to build my ultimate (well, for me, anyway) Mac Pro and will be installing a Sonnet 4x4 Silent. I'm considering the Crucial P5 Plus and the Samsung 980 Plus SSDs, among others; if you ran into compatibility problems with an SSD in this card, it would be nice to know which.

Thanks In Advance!
