szzs Posted February 14, 2020 Share Posted February 14, 2020 I just updated from RX 580 8GB to MSI Vega 56/64 reference card (dual bios!) . My system is rather old: smbios iMac 13.2 with ga-z77x ud5h / i7 3770K / 16GB RAM. I have in in my CLOVER/kexts the latest Lilu.kext and WhateverGreen.kext. These were enough for RX 580... BUT with VEGA there was not QE/CI - no acceleration !!! I found a preveious version of my EFI which enabled the acceleration, The difference is in Clover/Boot/Boot Arguments now: "shikigva=4", and "-rad4200" Also there is Clover/Graphics "RadeonDelnit" is checked ! That's all ! Now it seems that the card is working well, but I do not understand these setttings. PLEASE explain what does mean the values of "shikigva" (why 4) ? What is " -rad4200" ? Also help me when do I need the "RadeonDelnit" ? However, the card is now working but may be the setting are not perfect... Please help me in this setting, because this card is not very cheap, and I wish to have an optimal setting for my new VEGA card. Link to comment Share on other sites More sharing options...
