For me it looks like it is PCIe bus failure. The question is: Whats causing it.

For a $4000++ machine it should not matter. Apple should sort it out. This involves the computer crashing and not a beauty issue. It very embarrassing for apple engineering team. More than a year and no fix for their top end computer

I think it's time to get some apple care on this puppy, 10% failures is huge.
I already have!

incidentally as its been a while since I posted. I will give you an update.

I went into the Apple store here in London and took my mac pro in. They wanted to take the machine and have a look at it. I asked how long it would take for it to be sorted. They said 10 days. I asked for a new machine. As I paid all this money and think that I should be entitled to a machine which worked. They ordered another machine for me as my old own was customed built from the apple store web site.

A couple of days later my new machine was delivered so went back to the store and did a straight swap. I also made sure that my AppleCare was transferred to the new machine. I have had a few 'GPU appears to be hung' error messages but I still think this is software related. (or bug related) I am running el Capitan now and think that 10.11.2 might fix these graphic issues. I am tempted to install the beta version and to test it.

So far, and I'm not holding my breath obviously, since 10.11.2 I haven't had a GPU hang.

But

Before updating, I reseated the RAM* and tried a different TB port combination for my 2 screens.

I'll report back when the next GPU hang happens.

* I had to reseat RAM after taking the machine to the GB (again) for diagnostics. Never take computer to Apple with 3rd Party RAM installed.

I now got a replacement nMP after Apple couldn't supply me with unbroken D700s for three times. This machine now works flawlessly since one week fingers crossed. However I will instant sell this thing if the new gen comes out. Right now I think Apple just doesn't care anymore for this generation of Mac Pro.

I bought a refurb new mac pro base model last year and started having gpu crashes out of the box after I upgraded to yosemite then. I returned it to my local apple retail store after about 7 days from the purchase date and decided to exchange if for a new non refurbished new mac pro and paid the difference. Haven't had a single gpu issue since then. I currently have the latest beta installed on it. So Im sure my first nmp had a faulty gpu.

I use a small command line program that I wrote to get the main temps/fan speed
for this particular machine (nMP/3.7 GHz Quad-Core/D300):

https://www.dropbox.com/s/j6qcg84si1ie19i/smc.zip?dl=0

I can't really guarantee that it will work on anyone else's system, because I've only
tested it on my own. This is the sort of output I get from it:

Screen%20Shot%202015-11-08%20at%2011.20.36.png

The utility is provided "as is" and if you do use it, it is at your own risk. There
are, I believe, some alternatives out there. I just wanted something simple &
free for myself and something that I could use when logging onto the machine
remotely (i.e., not reliant on the GUI).

I am not sure this post is really that relevant to the problem discussed. But I
guess we have to consider all possibilities and some sort of heat issue is one.

Cheers.

Hopefully they'll introduce some kind of "Quality Program" replacement thing for affected machines, similar to what they are doing with the staingate macbook pros. That situation also had thousands of people posting online about it, and they listened.

I'm going to get applecare as soon as my next paycheck.

I don't think they will.

Its more a software bug then hardware I would think. for example when I had my mac pro tested their hardware test which where done at the Genius bar all came back fine.

Even Apples own hardware test which I did at home where fine.

When I booted the machine yesterday the progress bar on the monitor appeared, as usual, then the screen went black and stayed black. The monitor LED was blinking and I later found out that this is an error code. However, on rebooting the machine everything was fine. I have no idea what that was. I never had the monitor do that before. Unfortunately, I didn't realise at the time that the type of blinking indicates the type of problem, otherwise I would have observered it more carefully. Next time I'm on the machine I'll have a look at the logs.

Apple´s Service Diagnostic Tool does not thoroughly test Thunderbolt or GPU. OS X is real environment for testing. There is one more thing....there must be at least one person in Apple that can read 0s and 1s on our GPU hang logs.

when the genius guy was testing my mac he was using some very power intensive graphics. To the point the Mac pro was belting a lot of heat and I mean a lot of heat. It coped very well and despite the pasting the mac received it just handled it without any crashes what so ever.

Like I said before I think this is mac os x level and it seems to focus around windowserver process

If it is only a software problem, why some persons have freezes and others not?
It could be rouge software. Buggy software. Corrupt driver for example.

If it was hardware you would get freezes. Kernel panics. Whenever doing normal activities which does not a lot of hardware resources.

I have noticed in my console log that it always involves the windowServer process. This to me indicates that there is a bug within the process. Unless installing photoshop replaces the process I don't know. It never happened when I was running the os on its own without any of my apps installed.

Same here. Have you done basic trouble shooting ways reset pram. Clean install reset smc?

I still think it is a bug within the operating system. 10.11.2 apparently solves 'graphic' issues. But I would guess that is to do with the metal software side.

The SAV changes the SSD and have the same problems. So i filed one more time my nMP on the SAV.
If 10.11.2 solved the problems, i would be happy.

Anyone about 10.11.2?

Just to reiterate, after my GPU B and I/O panel and some other crap change, I was getting very frequent screen flickering on Yosemite but no hangs.

Since upgrading to El Capitan (2 weeks ago), I have not run into any problems.

I had kernel panics always associated with GPU restart/reset though. That was until they replaced my GPU-B, and now the machine runs fine except for the occasional flicker/artifact when first waking up from sleep, but thats probably just an older OS X bug (apple doesn't care anymore, they just pile on new features while ignoring old issues) when waking up with an external 3rd party monitor via HDMI
