MP 1,1-5,1 Simple question on flashed 4,1 (5,1). NVMe boot.

Hi there,

can a 2009 4,1 that has been flashed to 5,1 and running Xeon x5590, 3.46Ghz 6-Core CPU automatically boot from a PCIe NVMe card?
Thx

Needs to be on the current Mac Pro firmware (BootROM). See the first post of the thread below:

PCIe SSDs - NVMe & AHCI

This is a general info thread for blade SSDs that can be used in the Mac Pro. This is a WikiPost so anyone with the proper credentials may edit it. NVMe SSDs can be used as a boot drive in the MP5,1 and MP6,1 with the latest firmware installed (beginning with version 140.0.0.0.0 for MP5,1 and...

I finally got round to installing an NVMe SSD in my 2009 and clean installed Mojave with no problems. I was already on the latest boot rom though. Only thing is it is much slower to boot than with a PCIe SATA drive for example but so far so good.

PCIe SATA??? What do you mean by that?

I just meant the none NVMe SSDs on PCIe cards I have that are able to get SATA 3 speeds via PCI slots. Usually it’s just a PCIe card or adapter with a SATA port or two or there’s more advanced versions with different types of port and connections. NVMe is faster though but it’s slower to boot than the AHCI / SATA 3 cards.

I've had that experience as well, NVME was slow to boot Mojave but very snappy when logged in. I didn't see the point in continuing with the NVME (for me, others will have different uses) so I swapped it out for a pair of SATA SSD sleighs to get more fast storage.

Yep it’s not too bad but it’s just long enough to make me worry something has gone wrong! That is probably what I’d do too if I had to get another PCIe option. I moved my 3,1 to PCIe SSD so wanted a new option for my 4,1 but I’m trying to keep Mac Pro purchases to a minimum and hopefully only to more ‘future proof’ items.

Same here. When I eventually move to a full windows desktop (leaving my iMac as my Apple device) I'll have a ton of PCIE storage options lol.
