My NVMe's are a lot faster than my Sata SSD (Mojave), that is why I run Big Sur and Windows on them.

Are your NVMes Samsung 970 EVOPlus M.2? I have two of these but I can't get more than 1500 MB/s reading!
I know I should do a firmware update but I can't find a safe guide to do the update!
Do you have a suggestion?

Look for an adapter with the ASM2824 chip (like Lycom DT-130). I get 3200 read and 3000 write speed with the 970 Evo Plus.

This is totally offtopic here, but a PCIe v3.0 x4 installed on a PCIe v2.0 slot is limited to ~1450MB/s.
Only a x8 or a x16 PCIe switched card can overcome the PCIe v2.0 throughput limitation.
 
I have done it both ways (6-core & 12-core), but you are right about the second method being the easiest to fix, to be the same as your Catalina volume. Also, neither CCC or SuperDuper! will clone the EFI without further steps.

To do it automatically, you need EFIClone and CCC, as it doesn't work with SD. However, you can do it easily, post cloning; just copy and paste it onto the EFI partition of the clone.


One note on Big Sur cloning, it isn't possible yet with either CCC or SD. I have been reinstalling it and using Migration Assistant to update it, but there's still a lot of stuff to redo.

Good luck.
Took a bit but ended up using Carbon Copy Cloner to duplicate my Catalina drive, added in the EFI partition and then swapped disks and ran the update. Took a bit but it's done.

Only thing not working is Continuity. Just got that working in Catalina and I think there's a thread discussing it so I'll do a bit of searching.

My Syba has a ASM2824 chip and I can reach only the previous stats in Slot 2. I never hear anyone reaching 3200s on a 970 Evo Plus, I’m glad you get these numbers.
 
Yes, should be a BCM943602CDP card in it as well. I'll try signing in and out. That seemed to get it working under Catalina when it was first installed.
 
Hey guys, I updated to Big Sur today to see how it ran on my mac pro 5,1.

The only issue i've run into so far is that my highpoint NVME software raid doesn't show up. When I return to Catalina it is still there, however. Is there anyway I can save the configuration and import it into Big Sur?

Thanks!

Hi, could you please tell me the steps you made to upgrade from Catalina to Big Sur?
Thanks!

I also have the same controller as yours with 2 970 EVOPlus NVMe 1tb but can you explain to me how do you get such a high speed? I at most reach 1400-1500 MB /s!

I think your speeds represent the maximum available on the cMPs without a bifurcation card. I get your speeds or somewhat less with a 960EVO on my 6-core.

On my 12-core, I have the popular Syba /IO Crest PCI card which, in slot 2 (16x) allows for 2 blades (1 970EVO, and 1 970 EVO+ in my case) and PCI3 speeds, or almost. They both get 2.4GB/s writes and 2.8GB/s reads. The cards have a fan and are are heat sync, and cost around $200. My only complaint is copying between them is way too slow.

I have Catalina on one blade and both Mojave and Big Sur in separate APFS volumes on the other. I have not been successful using multiple boot volumes with the Opencore EFI Boot, and I've tried more than once, but not conclusively.

On the 6-core, I have Catalina (OC-EFI) on the blade, and both Mojave and Big Sur on volumes on a eSATA3 SSD. I am not sure, but believe I can just remove the OC-EFI from Catalina and put it on either of the other boot volumes. That way I can have Big Sur on the NVMe as the EFI drive. The only problem is that Big Sur doesn't clone with SD or CCC yet, but not without workarounds.
 
By the way, new CCC update hit last night to do Big Sur Bootable backups (not on M1s though). Click Check for update... I've not tried it yet on an OC cMP...

Sorry but there is a bit of confusion and in particular there must be a misunderstanding!
I have a cMP 5.1 12 core 2x3.46 GHz, 128 GB RAM with a Syba / IO Crest PCI card in slot 2 (16x) with 2 970 EVOPlus 1 Tb but which absolutely fail to reach your speeds (2.4 GB/s writes and 2.8 GB/s reads)!
They max out at 1.4 GB/s writes and 1.5 GB/s reads!
Could you tell me how did you manage to reach certain speeds on your MVMe discs?
Did you update the firmware at the 970 EVO! And how?
Thanks!
 
Brightness slider / Brightness setting with F1+F2 disappears, as soon as graphic boot picker is selected. Any idea why and how to fix it?

Is it necessary to remove the not supported WiFi-Card or can I leave it installed?

I don't know why you have a problem. I don't think it's the firmware, because I got one of the early PLUS blades before the new firmware, and it wouldn't work after a reboot with multiple kernel panics. I wasted two weeks until I found out the situation with the "Upgrade guide to the cMP" or something like that. Get it, it has everything about our cMPs.

I have heard that some of the newer bifurcation cards didn't work on the OC forum.

First of all, since you had it in the correct slot (my first thought before rereading your post), I can only think of two things. First I'd inspect it carefully for any anomalies as I took the card out. Then I would open up the card and take a look inside. Do you have the thermal material installed properly? I take it the fan was working. If all is well, I'd be contacting your supplier.

Check the upgrade guide, there may be something there I missed as to solutions. You might try to take out one drive at a time to test single speed numbers. That might indicate a hardware malfunction. Carefully reinstalling everything may even help. The fact that it works but not properly indicates a bad card or connection to me, but I only know enough to guess. Good Luck
 
Have you upgraded your card? Continuity working great for me with the card listed in my signature. I had problems in Big Sur but I fixed them by signing off/on on both iPhone and Mac.
I've given up for now. Logged out of iCloud on my phone and mac and no change except it complained that I couldn't enable the Apple Watch unlock feature because my watch wasn't connected to iCloud. Had to re-pair my watch and I'm able to enable the feature but nothing. There's a sight pause before the password prompt comes up which I assume is my computer looking for my watch. Can't even see it on Airdrop now. Maybe a few PRAM resets or maybe I need my NVRAM cleaned up?
 
I have a MacPro 5,1 dual CPU with Radeon RX 580 8Gb and it 's on Big Sur with HW Acceleration. I don't need use Lilu, WhateverGreen, and graphic card PciRoot(0x0)/Pci(0x0,0x0)/Pci(0x0,0x0). I just need AppleMCEReporterDisabler.kext.

My SMBIOS is MacPro7,1 (#5,090)

My config.plist is (attach files)
So I've tested with a RX580 (Sapphire Nitro+) and hwa disable (actually with the exact same config.plist). I had still the window laggy behaviour so I guessed it was not coming from there.

Found it, it was actually Rectangle that causes the lag. It works fine on my mbPro tho. I will investigate to check what's going on because it will probably happen with other app relative to window management.
