Author Topic: gMP5,1 GTX970 cannot sleep  (Read 5550 times)

The Mac can't sleep, not me.  Wink

If I let it sleep (initiated or by inactivity), I won't be able to log back in (past the gray login screen). Screens all stay blank and eventually go to sleep.
Then if I let it sit for a few minutes, it goes into a reboot loop.
Have to force-shutdown.

1. Specs:
  • Genuine MP 4,1 flashed to 5,1
  • eVGA GTX970 4GB with MVC ROM
  • OS X 10.3.2  (17C205)
  • nVidia web driver 378.
  • 3 x monitors (DVI, DVI, HDMI) all running at native 1920x1200
  • FileValut enabled.
  • Clean install 2 weeks ago.

2. This config is the first time I used all the above hardware, so I don't have "it worked before ___" info. I did run Unigine Haven on that card for half a day when I sourced it, with no issues.

3. Tried SMC, NVRAM resets, didn't help.

4. Haven't found a single similar case, about MP sleep issues (though I'm sure ye hardy hackintosh folks have experienced anything and everything). I read most of the thread on "High Sierra and nVidia drivers"; never had issues to make the OS use the nVidia driver, and once I'm logged in, things have been stable so far. (Next week I have a project on Adobe Premiere, which pushes the GPU and OpenCL way harder, so we shall see...)  Only time I saw lagginess was after safe mode when I was using the OS driver.
Was pondering if I should delve into Lilu's nvidiaGraphicsFixup, but from my understanding a genuine MP and a flashed GPU shouldn't need any of that. And from the discussion, those 378 drivers were actually considered among the more stable ones.

5. KP panic report:
panic(cpu 0 caller 0xffffff7f821eebcf): NVRM[0/5:0:0]: Read Error 0x00000144: CFG 0xffffffff 0xffffffff 0xffffffff, BAR0 0x92000000 0xffffff9ace1ff000 0x124020a1, D0, P1/4

6. I also have another exotic problem, when dragging windows from one monitor to the other, UI elements get blue or gray boxes.

Any thoughts?

May be you should try 10.13.4 and the latest web driver. It's much better than 10.13.2.

Anyway, sleeping is not even reliable on the newer 100% factory Mac. With a highly customised Mac Pro. I don't think it worth to spend time to fix the sleeping issue (there may be no work around apart from Apple fix it fundamentally).

With the SSD, boot up a cMP only need a few seconds. And since 10.6.8, I didn't see any macOS that can run few months stably without reboot.

So, may be it's better to make a full shutdown after you finish that section. And start from cold boot when you need it. For short period of time, just leave it normal idle.

If this was a widespread issue I would have heard about it by now.

It is likely something else other than the 970 card.

Before asking a question, check your "Personal Settings" and be sure that you have "Brain Services" set to "On".

Well now I couldn't login at all, from a cold boot. And I'm confident I haven't changed anything in the machine to warrant this different behavior. So it's more than a sleep convenience..

It's obviously a graphics issue, so what do you think would be suspect..?

I've been using Avid this month and last I checked the last qualified version was 10.13.2. But will backup and give 10.13.4 and the respective nVidia driver a try.

Do you have Avid PCIe card? Or for that matter any other PCIe card except GPU?

No Avid card, just a Newertech USB3 card.

I upgraded to 10.13.4 and sleep - at least initiated sleep - does work. (But there's an unrelated bug which Apple declined to fix whereas sleep kills power to PCIe cards so drives get force-ejected upon sleep. So I rarely use that feature anymore.)

But my problems only got worse. Will create a separate post since they have nothing to do with sleep anymore..
