Thanks, but either I miss the forest for the trees or it’s not there. I’m talking about a pcie Adapter card to put the original Apple Mac Pro drive inside a cMP.

Hi everyone.
This is and impressive thread. Kudos to you @CodeJingle and everyone else helping on this. Impressive indeed.
I've been playing with external GPUs connected to Macbooks for a while (via Thunderbolt) and the possibility to connect a third party GPU to a Mac Pro 6,1 came to my mind while reading this post "Late 2013 Mac Pro System Block Diagram" https://egpu.io/forums/desktop-computing/late-2013-mac-pro-system-block-diagram/ at https://egpu.io
According to this diagram your findings are correct:
- The CPU has 40 PCIe G3 lanes.
- 16 lanes go to each GPU .
- and 8 lanes to the PCIe switch located at the IO board.
- There are 4 additional lanes (DMI Gen2 ?) that go to the PCH located on the Logic board.
- This PCH provides PCIe G2 to the rest devices.
- among them, 4 lanes to the PCIe SSD storage located at GPU B board.
This architecture has a bottleneck when it comes to internal storage: 4 lanes will give us a maximum of 2 GBytes/sec (4 lanes from the SSD to the PCH and 4 lanes from the PCH to the CPU). I could connect a GPU to the SSD port (like this) but it won't be able to go over that limit.
External via thunderbolt won't help. Thunderbolt 2 has a theoretical limit of 2 GBytes/sec (that never reaches).
The Logic board brings the PCIe lanes coming from the CPU directly to the GPUs without any other steps in between (like your investigations confirmed) hence it should be possible to disconnect a GPU and bring these x16 to an external card. A very exciting perspective!
What I'm trying to do: I'm looking for a "Card breakout adapter" for the FCI Meg-Array connector (basically a connector already soldered on a board).
I don't have tools nor experience dealing with that kind of compact electronics and a card breakout adapter would help me to explore these connections and try to bring cables to a card.
This is the closest I've got: http://www.zebax.com/doc/ZX1/ZX181-Meg-Array.pdf
Unfortunately this one is for a 400 pins connector and not for the 300 we need
Congrats again and just mentioning this here in case one of your readers can help.
Thanks!
Juan
Oh my gosh. I'm so sorry - I totally misread your post. Whoops! That'll teach me for replying when I've just walked in from work. LOL.
I think Sintech make adapters. Haven't tried them, but I'm thinking about getting one too but found it hard to know which one to buy... http://eshop.sintech.cn/storage-adapter-20132016-mac-ssd-c-130_132.html
Thanks for the link. I will check it out and give it a try. Will let you know how that goes.
Since the serious stability issue has been narrowed down I updated the first post of the thread. On Mac Pro (late 2013) don't mix APFS and NTFS on the same NVMe drive. I will update if other stability issues are found.
Disappointing. The only reason I upgraded my internal ssd was to have a reasonable sized bootcamp partition. I hope they figure it out.
Outside of NVMe you are essentially describing the purpose of this thread. You are welcome to try it. Add your research journal entries to the thread.This is the closest I've got: http://www.zebax.com/doc/ZX1/ZX181-Meg-Array.pdf
Drivers from BootCampDrivers.com is required for boot camp on trash can. Absolute garbage without it. Latest Windows 10 runs 4k at 60 hz and can play games reasonably well on dual D700s. But you need BootCampDrivers.com otherwise yes agreed run in a VM.bootcampdrivers.com but was uneasy about non-authentic drivers.
You might as well DM me the entire image for the latest version of 6,1 firmware. Should only be 8 megabytes right?I'm trying to mod the cheesegrater BootROM to make it boot from FL1100 and I'm investigating ROMDumps of 5,1 and 6,1 Mac Pros.

You want to re-use nMP 6,1 SSD inside of cMP 5,1? There is no adapter for that currently. Maybe there is a market for this reverse adapter that does not exist yet.Isn't that just an m.2 adatper for m-key SSDs?
I would like to reuse my old original apple SSD inside a cMP 5,1
Instead of using the OWC enclosure, like you did.
I have two of those adapters, with SSUBX, seems a common one.You want to re-use nMP 6,1 SSD inside of cMP 5,1? There is no adapter for that currently. Maybe there is a market for this reverse adapter that does not exist yet.
Thank you for correction. In this case I love to be wrong! Yes that looks like Apple stock SSD slot in the PCIe adapter card.I have two of those adapters, with SSUBX, seems a common one.

Thank you! I saw that card and was wondering if it would work. I was just wondering why the nMP was not mentioned in any advertisement or description.I have two of those adapters, with SSUBX, seems a common one.

It's only a adapter, and not a good one, but works nicely. I bought a heatsink install kit too, SSUAX/SSUBX works a lot better with heatsinks.Thank you! I saw that card and was wondering if it would work. I was just wondering why the nMP was not mentioned in any advertisement or description.
Gonna order one of those!
In principle, the transplant should not be an issue yes? Thanks in advance!
I've received the Sintech C adapter which I bought to upgrade my nMP from 256GB to 1TB.
I used to switch the original SSDs from my MBPs (Late 2013, Mid 2014, Early 2015) to my nMP and vice versa: no issues at all.

Are there no sleep issues with such an adapter?
It should be the following, https://www.ebay.it/itm/Sintech-M-2...459516?hash=item1a59209dfc:g:kq0AAOSwSrxbMVvt Is it correct?
I can confirm that ntfs is having conflicts with apfs.
So is there any way I can use windows and mac together?
Yes ! Install Windows on it's own, dedicated spinner HDD - boot into EFI and select the Win HDD.
Works for me .. long bootup though = black screen with a blinking cursor for up to 1 minute. . then Bingo !
I haven't used Bootcamp for years as I only use Win for flashing GPU's .
Similar to feedback from MIKX, you can have a second NVMe drive and partition it as NTFS-only with no APFS partitions on the same drive. That should work and not crash. This is unfortunate for Mac Pro 6,1 since it requires a second hard drive located outside of the cylinder housing. This type of setup may also increase the difficulty of switching boot volumes.I can confirm that ntfs is having conflicts with apfs.

Except for Mac Pro 6,1 there is currently no evidence to suggest this bug exists on any other Apple computer. But no one has tried to reproduce this issue on a 5,1 or iMac Pro, at least no one that has gotten back to me. So there is a possibility.Hmm I guess that's for mac 5,1 not 6,1?
