d620osx Posted October 23, 2021 Share Posted October 23, 2021 (edited) Hi I wanted to see if I had any improvements if I move from a GT710 to a Quadro K2000, both are natively supported so thought if I swap the card it should all work, but it boots to a black screen with the mouse cursor. I have reset bios, tried with shikigva=40 but it goes past the OC picker and all the text but just ends up with a black screen with the mouse cursor. Are there any changes I need to make to the config or the system to boot using the Quadro K2000? Sorry should have said that the machine is a Optiplex 5050 i5 6th Gen. Thank you Edited October 23, 2021 by d620osx Link to comment Share on other sites More sharing options...
miliuco Posted October 23, 2021 Share Posted October 23, 2021 Do you have Lilu and WhateverGreen? Both are required. What SMBIOS do you have? 1 Link to comment Share on other sites More sharing options...

miliuco Posted October 23, 2021 Share Posted October 23, 2021 @d620osx iMac14,1 = iMac 2013. iMac15,1 = iMac 2014. Big Sur supported: iMac 2014 and newer. GT710 supports both SMBIOS. 1 Link to comment Share on other sites More sharing options...

d620osx Posted October 23, 2021 Author Share Posted October 23, 2021 Setting xhciportlimit to false has allowed me to boot using 15,1 with the gt710.Next step is to test the k2000.Thank you Link to comment Share on other sites More sharing options...

Slice Posted October 24, 2021 Share Posted October 24, 2021 May be you should think about NVCAP feature. Clover calculates it automatically but I have no advices for Opencore. 3 Link to comment Share on other sites More sharing options...

I said that if you choose Clover as a bootloader then you will have some options to adjust NVIDIA cards which Opencore has no. 2 Link to comment Share on other sites More sharing options...

This is so if you are using USBMap or USBPorts kexts. Inside them, Info.plist, there are 2 occurrences of the SMBIOS name, find them and replace with iMac15,1. Xhciportlimit always false except if you are using USBInjectAll.kext. I remember there was a problem with this quirk in previous BS versions, it’s possible that it must be false even if using USBInjectAll.kext.
