Hi everyone!

I'm aware that this thread is currently mainly related to the SSD expansion and upgrade but can anyone point me to pinout description of the meg-array GPU connector of the Mac Pro 6,1?

@CodeJingle did a lot of work on this in the past and there is information on this thread related to the connections of the CPU to the backplane connector (logic board) but after reading tons of old messages I can't find the result of his investigation when it comes to the meg-array GPU connector of the AMD FireProd GPU board in the Mac Pro.

Any information will be appreciated.

Thanks and happy new year!

Planning on upgrading my Mac Pro 6,1 to NVMe 1TB with the following:

Samsung 970 EVO PRO SSD 1TB
(all the reviews for this on Amazon state not compatible for Mac, however lots of people in here have used it with the latest firmware)

Sintech NGFF M.2 NVMe SSD Adapter

One of the reasons for upgrading is so I can partition and create a bootcamp for Windows. I have read elsewhere that a NTFS and APFS isn't compatible and will cause a lot of kernel panics. Has anyone had any experience with this? I'll most likely do a HFS and NTFS with Mojave. Are there any known issues with that setup? Thanks!

Yes, it is true and will happen. Has not been resolved. I ultimately bought a 1TB Apple part so I could do the same thing.

Another issue that I have with the current firmware is that when booting from Windows 10 back into MacOS using the "option" key, my fans stay at the speed the are during boot. So if they are at 790rpm when booting from Windows 10 to MacOS they will stay that way and cannot even be overridden. System must be shutdown completely and rebooted for fan controller to function properly. I'm on Catalina, latest build of windows 10 and latest bootcamp but this has been an issue for a long time. No, resetting SMC or PRAM does not fix it. I think its just a flakey bug that will never get fixed. This is a 6,1 with Apple 1tb and 64gb apple ram, and 8 core.

Anyone know a reputable store to buy one? OWC is selling a used one that's $238 (a whole $10 cheaper than a new one). I don't like the idea of buying a used hard drive and that its $10 less. But, OWC has cornered the market.

ipowerresale is a good source for mac pro 2013 systems and upgrades. They are who i bought all of my stuff from, so might give them a call.

Just upgraded my 6,1 with both MacOS and Windows partitions to 970 EVO Plus 1TB (with new firmware). I got a Sintech NGFF adapter (latest version, see photo below).

Problems encountered:

- The heatsink product recommended in this thread was a disappointment. The thermal tape protective layer didn’t peel off correctly, and left a very thin plastic layer I had to remove it using a cutter (and a lot of patience). If you have thermal issues, it might be due to that almost invisible layer left on the tape. You can notice it because it is slightly reflective.

- I had to cover the base of the adapter pins because the heatsink backplate was almost touching them.

- I cloned the drive and then moved the Windows partition to the end of the new one. So I could finally grow my MacOS partition. At the first login in Windows I got immediately a bluescreen caused by the driver of an unrelated external USB device. Now Windows tells me I cannot login into my original profile, and I got assigned a new profile. Never seen anything like that. Corrupt profile due to bluescreen ? But apart from that, everything seems to work fine in Windows.

- The 970 EVO Plus has a chip that is less thick than the others. Had to use two layers of thermal tape to put it in contact with the heatsink.

- Randomly, I cannot get to the boot selector using the ALT key, and the system is stuck with a black screen. All that is needed is a power-cycle, and then it works again.

Apart from the above issues, the system runs fine. I haven’t used it much though, so can’t be sure everything is 100% ok yet.
Speeds in MacOS are around 1400 MB/s both read and write.
I kept the original drive for firmware updates.
Oh, and I have a good external backup disk ;-)

It’s most probably a timing issue.
I have a third-party USB keyboard going through a hub. I can’t stand Apple keyboards.
But I also have to use an additional ultra-small USB keyboard directly connected to the Mac to use just for startup keypresses. Works for me.

I thought that the product would bring larger handles (metal tabs to hug) bigger, it has been a nuisance and a problem, it was impossible to hug.

As I did not understand, browsing in Amazon a user was already talking about the 970 pro, I could only hug the handle if you put the thermal foam of a millimeter on the chip part and left the 1.5 for the furthest part of them, you idiot of me don't remember that the ssd is plugged into a Sintech NGFF M.2 nVME -

I finally gave up

anyone finds the right handles 😳

I also have doubts if the screw will be short

I will have to reread the forum to see how users have gotten their sandwich, however if someone has been through this I appreciate your help

Yes, that product is disappointing.
Use only the thinner thermal pad. You barely have enough of it, so give precedence to the chips on the top side. Even better, buy a decent thermal pad, because the one provided is crap.
The metal clips will be easier to fit if you first stretch them out with your hands to make them looser.
About the screw, don’t worry, it will not be too short. Do not over-tighten the screw.

Thank you Dan Streaman

I will take into account the search for a good thermal material, the solution of leaving the finest thermal layer only is also appreciated, the problem of the handle is frustrating, but I already went through the sensation when placing the handles to break the ssd, maybe The solution is to flatten the S-curved handle completely and make a U-shaped mini fold.

Where the hell can you find slightly larger handles?

Thank you
