I suggest you to wait for macOS 12.4 to see if a new firmware comes out to fix sleep issue. There is a new sleep crash reboot, macOS 12.4 should come with firmware 430.x with this fix. I had no more D300 crash anyway.Base D300 MP6,1 on Mojave here.. no 4K screens, but am running 2x 1080p plus 1x 720p projector simultaneously. It's been ROCK solid, not frozen once (it was a regular occurrence on prior MacOS).
Is there a clear risk-free upgrade route?? I'm enthused by your post @ikir
But if doing same here doesn't result in a stable system, I presume firmware cannot be restored?
Crash happens with firmware 429.x we need 430.x which was pulled in beta probably for other bugs. Lets hope in macOS 12.4Regarding my earlier positive results with manually sleeping 6,1 D300 for a night, I tried a longer sleep of two hole days, and it crashed.
Are you still crash-free at this point on 12.3?Crash happens with firmware 429.x we need 430.x which was pulled in beta probably for other bugs. Lets hope in macOS 12.4
Other than sleep issue hopefully fixed in 12.4 I had no more GPU crashes. thermals are ok anyway since I've cleaned and changed thermal paste before the upgrade.Are you still crash-free at this point on 12.3?
Some of my software has hit a wall with Mojave and it's a shame this machine can't go beyond that...
It's sort of a combo of hardware/software issue. My posts on this are pretty far back in this thread, but I relentlessly hassled Apple until I somehow got to a senior tech. He fiddled with the issue a few days and found it could be fixed with software, so he sent it to the OS update crew to put a fix in Mojave...this is why it works perfect in Mojave. Catalina broke it again.So do we know if it is a hardware or software issue? Those D300 are curse! I’m still on old firmware because third party SSD, I’ve ordered an original one so I can update to Monterey (and update firmware).
Does it happens on Mojave too?
So you are still on 429.xxx? Mine is pretty stable now thanks to 430.xxxOk, well, it didn't take long, only a few hours for a massive series of GPU restarts still, and then a timeout spin, then a kernel panic. Information being sent to Apple.
Yes, I am on 429.xx. Where can I find 430.xx? I don't seem to have access to 12.3 b5.So you are still on 429.xxx? Mine is pretty stable now thanks to 430.xxx
Disclaimer: I wouldn‘t install a beta firmware that Apple withdrew and seems to bring along other unforseeable behaviour. I would wait (hope) for a GM firmware as downgrading back to 429.x is impossible.Yes, I am on 429.xx. Where can I find 430.xx? I don't seem to have access to 12.3 b5.

It's mostly stable while I am actively using the system now, but... I still see GPU restarts during the day and sleep mode is turned off. Certain games just crash because the graphics goes offline.Disclaimer: I wouldn‘t install a beta firmware that Apple withdrew and seems to bring along other unforseeable behaviour. I would disable sleep and wait (hope) for a GM firmware.

I shut my down at night now when I'm not using it. I've switched to Firefox also. It's... lessened my occurrences, and the machine is useable, but I will still get a crash here and there. It's like learning how to live with a new cat...Greetings fellow freeze/crash sufferers!!
Just wanted to add my voice to this thread. Purchased a used 6,1 D300 machine around Feb. 2022 and it was humming right along until five days *after* the return period! I was not aware of this GPU issue and none of these topics came up on my pre-purchase research, so stinks to be me (and us), eh?? The Mac Pro is now back at the vendor, where they are essentially saying "We've tested it and have found nothing wrong".
Data Points
Anyway, I too was having the .gpuRestart events. It really didn't seem to matter which apps were running and I *never* sleep my Mac -- I only sleep the screen using a hot corner. I use a low-ish resolution screen (1920x1200) connected to my 6,1 with a mini DisplayPort to DisplayPort cable (I don't use HDMI). Crashes/freezes started one day about thirty-six days after starting use of the machine. Running latest Monterey macOS 12.2.1 and firmware 429.60.3.0.
Crashes/freezes would happen with no apps running, while the monitor was sleeping, during a normal workday with Firefox, Thunderbird, Adium and Geany running, another time the issue happened while viewing a low-complexity 4K YouTube video in FF.
I don't get too crazy with installing a bunch of apps as I try to be as minimalist as possible. I do, however, need some stuff on here because I'm a developer and require certain tools for coding and testing in virtual machines. The major apps I've installed are Xcode, iLife stuff (Pages, etc), Lazarus IDE, MacPorts, Geany, Firefox, Thunderbird, Adium, LibreOffice, VirtualBox and Keka.
The 6,1 I'm using has an OWC Aura Pro SSD and no other hardware modifications.
Anyway, I haven't had the time to read this complete thread, but do hope this gets resolved someday -- otherwise I have a very expensive paperweight!
