Dell UP2715k with GTX 970

[Helmi74]

Hey there,

my quite freshly running Hack still needs some tweaks (iMessage for example) but today the new Display arrived \o/

I instantly put in on my crafting table in the basement and hooked it up to the already running Hack and it looked brilliant. I'm not exactly sure which resolution I got but it definitely was recognized as HiDPI display. The monitor settings showed the usual zoom-level settings that are shown on for example the Retina MBP.

Unfortunately the glory was gone when I rebooted the first time. I had crashes and couldn't boot anymore. I found out that the Display seems to have problems showing BIOS level output which makes the BIOS and the Clover menu unreachable for me. After setting nv_spanmodepolicy to 1 i finally managed to get the machine booting again. I only see output when the Desktop is already loaded a few seconds and the resolution seems to be Stuck at 2160x1440.

I found some posts from over a year ago where most tipps relate to new drivers that were needed back than but I couldn't find any more valuable information.

Does anyone have a similar setup running?

Currently i'm running the Hack as iMac 17,1 but i'm not sure if this is the right choice yet.

I'm on an Asus Maximus VIII Hero, i7 6700K, 32GB Ram and a EVGA GTX 970 SSC - i thought an iMac 17,1 is something that should fit quite well.

Any input is highly appreciated.

Thanks,
Frank

I have a GTX 960 with UP2715k

The setup is not perfect, but it's working -> display recognized as 5k, hidpi settings are supported.

I assume you have the recent Nvidia web drivers installed.

Clover boot arguments:
iMac15,1
dart=0 nvda_drv=1 kext-dev-mode=1
(yes, nv_spanmodepolicy is not activated)

Kext patch:

                <key>Comment</key>
                <string>AppleGraphicsDevicePolicy (board-id) Patch (c) Pike R. Alpha</string>

                Ym9hcmQtaXg=
                </data>
            </dict>

AND applying agdpfix

Kext patch details and agdpfix available here in first pot: http://www.tonymacx86.com/threads/b...-imac-15-or-imac-17-system-definition.183113/

I need both methods at the same time to make this monitor work. In theory both methods should do the same, however, if I only apply one method, the monitor doesn't work properly.

But here are the downsides, for which I've found no solution yet:
- You have to apply agdpfix with every system update
- The system only boots if the monitor is disconnected from power. Otherwise the system reboots endlessly just before the login screen.

So my procedure for now is:
- disconnect power from monitor
- boot hackintosh
- attach powercord to monitor again

This is the only way it works for now.

Thanks @XQC this sounds interesting. I'll try that out. I have the kext patch already i think but I need to look at agdpfix. And yes, I do have the latest web drv from Nvidia.

Do you have energy saving disabled on the display itself? Currently I don't even see the Clover menu - not seeing BIOS stuff seems to be quite normal with this Display.

 

[XQC]

BIOS and Clover are displayed without problems and I didn't set anything special for it. Monitor settings are default.
Only things that come to my mind:
- Intel GPU disabled in BIOS?
- CSM enabled in BIOS?
- CsmVideoDxe driver active in Clover?

If you even don't see the bios, then try the internal gpu output from your mainboard (if not deactivated) and only one displayport cable. This should work.

 

[Helmi74]

Thanks so far for helping. I got 5k working \o/ - i will now see how booting goes and care about the BIOS. Good to know you got it working.

I don't know if both options (CSM and CsmVideoDxe) should be active but I guess? I just activated the driver in Clover and see the BIOS settings now.

 

[Helmi74]

Ok, so here's what i got:

1. I see the same reboot loop that you see when I leave everything plugged in. I don't see any BIOS or Clover then
2. If I boot without the display beeing powered it works - same as it does with your setup.
3. If I boot with only one DP plugged in I see the BIOS, Clover and can boot without reboot. Plugging the second DP in after the system has booted (which shows up in 1440p at this time) I get the full 5k and everything looks great.

So I still have to find out how to see BIOS and clover with both DP plugged in and ideally we have to get this reboot loop fixed. Have you already seen anything from what happens there? Maybe some system log entries or anything like that?

- Intel GPU disabled in BIOS?
- CSM enabled in BIOS?
- CsmVideoDxe driver active in Clover?
​

I haven't found any Intel GPU settings in my ASUS BIOS. Any hints appreciated.

CSM is and was enabled in the BIOS and I have CsmVideoDxe drivers enabled in clover via CloverConfigurator.

Any other ideas relating BIOS and Clover?

 

[XQC]

I have a Gigabyte Motherboard.
Only other option that comes to my mind is that I can set which display output should get priority (internal gpu or pcie slot).

I disabled the internal gpu and set the priority for pcie slot.

It seems to me that both your BIOS and Clover are listening on the internal gpu output, but not the nvidia gpu.

 

[Helmi74]

Ok that is something I can set and just have set from Auto to PCIEX which didn't change anything unfortunately.

 

[XQC]

And regarding the reboot loop:
Yeah I think we're on the same boat now.

Scenario 1 - Only one DP cable: Booting works, 4k resolution works and 1080p hidpi is available.
Scenario 2 - Two DP cables, Monitor powered on: reboot loop
Scenario 3 - Two DP cables, Monitor powered off: Booting works, when monitor powered on again, 5k works and 1440p hidpi is available

Other scenarios:
kext patch 0, agdpfix 0: booting works, but black screen (system is responsive)
kext patch 0, agdpfix 1: booting works, only normal 1440p available (non-hidpi)
kext patch 1, agdpfix 0: same as above, but screen flickering and only normal 1440p available (non-hidpi)

So I came to an dead end here, hopefully other guys have a solution for this

 

[Helmi74]

Here's an error report I got when booting and this is from the boot attempt before where the "reboot loop" thing occured. Maybe this is something that helps for debugging.
