So, I sold my eGPU setup, which was a GTX 970 in a Thunder2 enclosure using a Corsair VS550 psu. Worked fine when I owned it, my MacBook died, so I've sold it to a friend.
Set it up fine on his mid 2012 MBP no worries, everything seemed to work fine at first. Now, a day later, every time he loads heroes of the storm (or any game for that matter) the computer black screens and resets, throws up a GPU panic error code. Sometimes it will last a little longer than others, but the predominate issue is that the fans often aren't spinning when the radiator gets hot. The fans work, because they spin up on start up.
Ideas for what could be causing this issue?
So I'm having a little issue with my egpu setup and if anyone could give me some hinters that would be great.
Basically I've done this before with this same laptop on a 980ti which worked perfectly and now I have a 1060.
Only problem is, I've installed everything correctly, theres no error messages in device manager, says this device is working correctly BUT when I go to play games, it decides to run the dgpu instead. Now I've run some benchmarks and the 1060 is being used, getting 150fps. I do have to disable the AMD though.
So, my question to the pros is, what happens next?
I've tried using the latest drivers from nvidia, tried uninstalling everything with Display Drive Uninstaller and trying again, tried using a safe driver version (372.70) because I read the latest one was buggy..
Tried uninstalling and disabling microsoft basica display adapter only to get the same results..
I also get an error when trying to access nvidia control panel "nvidia display settings are not available, you are not currently using a display attached to an nvidia gpu" but it shows in device manager as "working properly"
It also doesn't show in dxdiag as well. only shows the AMD.
I'm not using an external display if that helps..
any help would be appreciated!!
EDIT: I have been getting code 12 errors with my current driver 372.70
Does this mean I need to do a DSDT override?
I'd like to not have to deal with coding etc but if necessary then I can try.
I have tried to update to the latest driver version but that hasn't really been helping either.
I have a problem with my rig (Win7, at the moment nvidia 372.90 ). Everything works for some time and then then its gets nvlddmkm.sys error (stoped responding and recovered). In best times its recovers but sometimes I get BSOD.
I have tried different drivers, TdrDelay, TdrDdiDelay, HDMI audio off, power to max peformance in nvidia controls, Gen2 to Gen1 in BIOS.
My brain is fried allready :S
Can anyone give me some clues or solutions?
For the first, here is my system:
- MacBook Pro, late 2015 (no dedicated graphics card)
- Mac OS Sierra 10.12.4
- Akitio Thunder 2 (with additional 650 W power supply)
- Nvidia GTX 980 ti
And now my problem:
After about half a year my eGPU setup suddenly stops to work.
When I start my Mac with connected gpu up, the boot process crashes.
Some days ago I made an update from 10.12.3 to 10.12.4 and update the NVIDIA web driver. After this my setup works just like befor.
It was not the first time I install an update.
But today everything goes down.
Here are my vain try's to repair the system:
1. reinstall automate-GPU; Automate recognition the graphic card but the mac still not boot
2. Try to use automate-GPU "-a" mode
3. Disable csrutil in recovery mode
3. Play back old timemachine backup (SAME PROBLE, THE MAC DOES NOT BOOT!)
4. Install clean Mac OS from recovery (does not work to..)
All this measures have brought nothing...
Do someone have the same problem like me?
If someone has a ideas what to do, please let me know.
[SOLVED : Cpu idle bug fix without hibernating!] MBPr Late 2013 (dgpu) + GTX 970: Optimus working, "cpu idle bug"By dnkei
EDIT: SOLUTION on my 4th post.
I just wanted to know if anyone found a fix for the cpu idle bug without hibernating.
First of all, I made my setup in 2015 and I just used an external monitor since at the time making it work with optimus having a dgpu was unknown. Recently I read that disabling the dgpu was an option so I quickly got "up to date" reading the new stuff, but I might have missed something. Keeping that in mind:
I have a MBPr Late 2013 (GT750M dgpu) with an Akitio Thunder Box, with a dell power supply (which I always thought it might not be enough because I had to limit the power with Afterburner to 80% so it wouldn't shut down when playing a few hours) and an Nvidia GTX970 (KFA 4GB).
Since I was using a Win 7 on Bootcamp/BIOS I decided to start from scratch: got a Win 10 EFI installed, got reFind so I could activate the visibility of the Iris igpu, and although it seems to be much more buggy, got to run the system with the egpu. Then disabled the dgpu on the device manager, used the switch-gpu bat file as admin to get the igpu as main, so far so good. Shut down, Boot.
I get to the point where I basically have the egpu working and I tried running Tomb Raider's benchmark (what I had at hand) and it was going smoothly (which wouldn't be like that with the iris or dgpu). Also, looking at msi afterburner my egpu was at 100%.
The ONLY thing that I can't by any means get to work is to not have the CPU idle crazy load. I get around 25-30% of CPU load and if I try to hibernate the system it... well it goes to hell, haha.
The MBP seems to hibernate (sleep/shutdown black, fans out) but the egpu is still on with the fans (doesn't really hibernate), and from there its impossible to make it run. Pressing any button, alt, power, whatever, it tries to wake up/power on for a moment, but it simply can't finish, just black screen with the fans turning on. The only way to shut it down is to hold the power button. And after that it basically locks there and becomes even difficult to boot again, I actually have to press alt, go back to osx, reinstall refind - since it no longer appears with it trying to wake up from hibernation- run windows efi and quickly press shift+f8 to run in safe mode and then boot correctly (and again with the cpu load).
I have to say that even when working, my macbook pro doesn't consistently boot with the egpu via thunderbolt2, with any combination (wait to plug the cable, have it powered on, off, preboot, when starting windows, etc.) it just seems to randomly work. It used to work a bit better before refind, though, but never consistently (don't know if that has changed in the past years).
So... any ideas of how to get that cpu load off? Or to make hibernation work?
Oh, as a note, I read that when you disable the dgpu and use the switchgpu script you can control the screen brightness again, but I just have it locked to the max. The control osd appears and moves but it doesn't actually change. I don't care about it but I thought it might give a hint of something not done properly?
Many thanks to whoever can give me any ideas!!!
EDIT: Reduced part of the cpu idle from known w10 small stuff but the main bug is still there, about 15%)
