hello everybody!
I need to ask if someone over here might have any idea why my Mac Pro 5,1 mid 2012 won‘t take a Sonnet NVME M.2 4x4 PCIe Silent Card which was equiped with four Crucial 1 TB P5 Plus NVMEs. I had Mojave on a 500GB SSD running and when the Sonnet card had been installed the machine would hang for a few seconds in the beginning of boot then shutting down, restart and again hanging, shutting down, restart and so on… On Sonnet webpage the crucial nvme is said to be compatible with the card…would be great if there would be a solution so I could make use of the expensive NVMEs.

thanks in advance
 
Contact Sonnet Tech Support. I have found them be exceptionally responsive when users have problems.
hi thanks for replying! Unfortunatly I already asked there but was told to check out the function from all sides (empty card, other NVMEs, on slot after another) which I already did when contacting Sonnet support and since I bought the card in used condition so I didn‘t want to ask more of their time…the crucial NVMEs are brand new and only initialized via external conection. The crucial NVME are in working condition (tested with an external nvme cover from Arcasis), the card works ( empty and with Samsung 980s - tested with slot one and four, same as with the crucial stuff)
 
Can your cMP boot with an empty Sonnect card? (No NVMe installed)
As I said above - Sonnet card has been checked (empty after with crucial in all slots, with one crucial in first slot, with one crucial in last slot, with one samsung in first slot) anyway - with crucial the machine would restart steadily after some seconds. Also tested PCIe Slot 1 - system only hangs without tending to restart…

would it make any difference having the crucial installed on the Sonnet NVME card or in my Acasis enclosure where actually one is mounted as time machine volume…?

It can make some difference.

At least, it's impossible to boot from NVMe via a USB 3.2 connection on the cMP.
 
True, but that is caused by the usb connection where it is not possible to boot from…the pcie connection should not have such limitation. Still no real logical explanation for my problem….
 
When a M.2 blade is installed to a USB case, it's a USB device that interacts with the Mac Pro firmware via a USB controller, with no OPROM.

When the M.2 blade is installed to a card, switched or not, it's a miniaturized version of a PCIe card, interacting directly with the Mac Pro hardware and firmware. If the M.2 blade have a OPROM that interacts badly with the EFI, like Samsung 950PRO, won't work. If the blade have a controller that requires a specific or newer NVMe firmware than v1.3, like several Plextor and Samsung enterprise models, won't work. If the M.2 blade requires UEFI 2.3.1 and newer, instead of Mac Pro EFI v1.10, won't work.

Never buy a NVMe blade/drive without checking if it's one on the supported list. Crucial have an extremely poor track record with Mac compatibility.


P.S.: I bet that Crucial P5 Plus is requiring HII services or something that is not present with EFI v1.10, like recent GPUs.
 
OK, thanks for the overview! Now I have something to look after when searching for information. As it is I am a newbie in Apple affairs so me myself does not have any knowledge of EFI versions and roms…

kind regards

Hi, I only read your post now, because I purchased an "OWC Adapter" and a 1TB "crucial p5 plus".

I tried to install it on all three slots, but my Mac Pro Mid 2010, 5.1 after the start of start -up stops.

If only the adapter installs, the computer is normally settled.

My firmware is 144.


[Ciao, leggo solo ora il tuo post, perché ho acquistato una “OWC adapter” ed una “Crucial P5 Plus” da 1Tb.

Ho provato ad installarla su tutti e tre gli slot, ma il mio Mac Pro mid 2010, 5,1 dopo il suono di avvio si ferma.

Se installo solamente l’adattatore, il computer si avvia normalmente.

Il mio firmware è 144.]

In the end what brand and model did you buy?

[Alla fine che marca e modello hai acquistato?]
 
Hi. A little late to the party on this, but have just encountered a similar issue to the OP, whereby installing a 1TB Crucial P5 Plus NVMe blade mounted in an Aqua Computer kryoM.2 adapter in a Mac Pro 5,1 x4 PCIe slot halts bootloading at the outset. By process of elimination, it seems P5 Plus compatibility may be source of the problem. P3 appears to work tho.
