So I got the kryoM.2 evo PCIe 3.0 x 4, adapter, since it’ll limit speeds to 1,500 anyway, should I NOT get the Samsung 970 Evo Pro?
It's up to you. Depends on price, and what you want to do with it in the future (move it to a newer computer or a PCIe 3.0 capable PCIe slot or M.2 carrier card).

I'm buying one Samsung 970 EVO Pro 1TB for now to use with the KryoM.2 Evo PCIe 3.0 adapter but in the future I am planning to get the High Point SSD7101A-1 NVMe RAID Controller with three more NVMes because I just found out that just because you can fit four inside, doesn't mean it can only read four as one. I found out you can break them up i.e One NVMe for boot and apps while three are for scratch disk purposes at RAID 0 etc...

I was under the impression that four NVMes would be read as one and you had no choice but to RAID them all up.

I upgraded the NVMe in my MBP and transferred the old blade (Adata SX8200 480GB) to a KryoM 2 evo in my MP 5,1 (2010) on the latest bootrROM. There were two volumes on it, Catalina and High Sierra. I selected the Catalina volume in the boot screen and got a No Entry sign. Both volumes vanished from the boot screen on reboot.

Booting from an existing Mojave volume on the MP, I couldn't see either volume either, only a popup warning that a device was unreadable and did I want to initialise it? Disk Utility only showed the blade as a 2262 media and unformatted and with a capacity of 1TB, which is twice the 480GB it should have been. DriveX sees it as an object and isn't reporting any hardware issues.

Is there something I have missed? I don't want to reformat the disk if DU isn't reporting back its correct capacity in case I end up mangling something I shouldn't.

You can't install Catalina with a supported Mac and then run it with an unsupported one without -no_compat_check.

Code:
sudo nvram boot-args="-no_compat_check"

Forgot to say that that particular NVRAM string was already on board as I had an installation of Catalina on a spinner already just to test in case I wanted to upgrade to it at some stage. I would understand that otherwise it wouldn't be seen as a bootable volume but for the whole volume to suddenly disappear, taking High Sierra with it, is taking unsupported to a whole new level.

Hello and thanks for the great recommendations here. I am installing the KryoM.2 Evo with a Samsung 970 Evo 1TB and I followed the steps outlined by bxs in the MP 7,1 thread. I dropped in the underside heat sink and one thermal pad (I had to cut it because it was too long, and I did remove the thin plastic films on both sides of it) but when I went to plug in the blade I noticed that it doesn't rest flat (see attached pic). It appears that the thermal pad is too thick? I can gently press down the blade but it seems like it's going to bend, and that doesn't seem right.

Should I just remove the bottom thermal pad? If I do so the blade rests nice and flat, but I don't think it makes full contact with the bottom metal sink.

I have exactly the same components and also noticed this when installing the 970 EVO - although mine did not appear to stick up as much possibly.

I assumed it would be OK (I pushed the 970 so it was flat with my fingers and it seemed not to "bend" the card too much or pop it out of the connector) so I went with it - put the heatsink over it and screwed it down and installed.

Has now been in machine and running for 1 1/2 months and no issues. Temps OK (40-41 Celcius).

The pad beneath and above should compress a bit so I imagine the card won't be pushed competely horizontal (maybe).

Is it OK? Some may say no - but this is my experience and appears to be OK.

Thanks for this background, it is helpful.

I just worry that if I do the same the center of the blade will bend too much. I don’t have a good grasp on how much is too much.

Or are you saying that basically once you apply the top pad and heat sink that pressure will partially even out the bending caused by the bottom pad/sink?

Not really. I meant that the pads should have a little bit of compression (probably not much) and that when you apply the top pad/heatsink the pad should compress a bit to accomodate the stick - not explaining this well - sorry.

Basically - push the stick down with finger with bottom heatsink/pad installed - should not bend further than that when top is installed.

Got it, thanks for clarifying -- another option i thought is, would it make sense to install it with the heat sinks without the thermal pads (or at least without the bottom pad)? Not sure if the heat sinks would effectively... sink any heat without the pads.

Thanks all....just wanted to report that installation went well even with some minor bending. I did end up with a compromise. The original bending seemed a bit too much to me, but I didn’t want to go with no thermal pad at all. So I trimmed the lower thermal pad along all sides, and applied the rest in the center of the bottom heat sink, squeezing it down with my fingers and pulling it apart gently to make it flatter (see pic). This way I got the angle between blade and card down to around 2-3 degrees only, so it seemed fine. The bending was barely visible.

I didn’t haven any such issues with the upper thermal pad.

After installing the card the system recognized it right away and temps per DriveDx are 30-32 C when idle. (Haven’t had the chance to actually use the drive.)

It's the LogicBoardSerialNumber, you will need to take a picture of the label at the left of the male CPU tray connector on the logic board, you will need to take out the CPU tray cage.

Your BootROM is working as is with iMessage, but it's better to have the correct LBSN on your BootROM. Apple change the requirements of iMessage validation frequently, trying to stop the hackintosh crowd. Last time they changed it, I lost the ability of login with Fusion VMs even with all the ids correctly defined into the VMX file, iCloud even thinks the VM is a Mac Pro (I use the data of a defective logic board that I have).
This is msg for @tsialex - I would like to ask you for some specific unrecovered MacPro4.1upged to 5.1 PROBLEM, but I cannot contact you here. PROBLEM: I have 2 CPUs board and Iam not able to use any of 5–8 RAM slots - MAC not boot or unattended shutdowns ... I realy do everything from 12 different checked sets of RAM modulse, any type of congigurations, all disasembeled tried 4 different CPU boards to eliminate rest MAC HW problem stuff till ASD AHT testing and another SW tools but "all stills looks working" but its not true. If I use only slots 1–4 everything is OKAY. I have used and using this MAC everyday a now Iam in this situation. Please can you help me? How we can contact due the rules here... Thank you and looking forward for your answer.

So I bought this adapter and the Samsung 970 Evo Plus 2TB, put it together and am ready to install it in my Mac Pro 4,1>5,1 (with firmware 144.0.0.0.0).

Can I just install it in any slot or doesn’t it matter, speed-wise or maybe even fan-wise?

Also, I already have another sata-SSD in the top slot. Do I need to move it to another slot, or remove it altogether? I can put it in a HDD bay with an OWC adapter I have or put a case around it and use it as an external, but I’d prefer it to stay where it is now.

You mean your existing SATA SSD is in a PCIe card in slot 4 (the top slot)? That is fine, you can leave it there if you have another slot free for the KyroM.2. I assume you have a GPU in slot 1, so if both slot 2 and slot 3 are open then you can put the kyroM.2 in either one. The card will only use 4 PCIe lanes, so it makes the most sense to put it in Slot 3, which is x4 electrically (even though it's an x16 slot physically). You could also put it in slot 2 with no problems--just understand that slot 2 actually has 16 PCIe lanes available, so putting a x4 card in there isn't using the slot to its full advantage. But if you have nothing else to put in that slot then it doesn't really matter.

For cooling, maybe it would do better in slot 2, since that would allow a bunch of air space between it and your SATA card. But assuming you have a double-height GPU, putting the kyroM.2. in slot 2 would have it sitting right above the GPU. You could try it in both slots and measure temps if you want (Macs Fan Control.app is free and will usually show you the temps of your NVMe SSDs. Other apps will also).

Thank you very much, bookemdano! I have successfully installed the Aqua in PCIe slot #3 and all seems well.

I first tried the ”Restore from another drive” option in Disk Utility but that didn’t work. Near the very end it would fail, something about failing to invert the volume, or words to that affect. However, DriveDx showed the drive was perfectly healthy, so I assumed the problem was with Disk Utility and then used Super Duper to clone my boot drive and that worked.

My old Mac Pro is now about three times faster than with the Sata SSD. Very happy with this.
