Moderators Jake Lo Posted October 13, 2015 Moderators Share Posted October 13, 2015 Did you follow this? See here regarding DVMT. Without that mod, you will not get full graphics acceleration (QE/CI). Yes, you still need to check and change if necessary because different versions of Windows reports differently. So to really be sure, follow the guide. You could skip numbers 1 -> 4 unless you want to see for yourself the process. Start from 5 to 8. At #8, you could just run setup_var 0x15b first just to verify before running setup_var 0x15b 0x3 setup_var 0x15c 0x3 If you really don't want to mess with the BIOS, you could just add this to the Config.plist under KextToPatch. Use PlistEditor or Textedit <dict> <key>Comment</key> <string>10.11 (based on Austere.J patch)</string> <key>Find</key> <data> QTnEdj4= </data> <key>Name</key> <string>disabled:AppleIntelBDWGraphicsFramebuffer</string> <key>Replace</key> <data> QTnE6z4= </data> </dict> Link to comment Share on other sites More sharing options...
dstrukt Posted October 13, 2015 Share Posted October 13, 2015 Thanks. I did go through the steps now and I'm about to change the values. Did you see my previous post about the error I got when booting? I provided a screenshot. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 13, 2015 Moderators Share Posted October 13, 2015 Yes, the KP is due to AppleIntelBDWGraphicsFrameBuffer requiring DVMT pre-allocated memory in BIOS set to 64mb or higher 1 Link to comment Share on other sites More sharing options...
dstrukt Posted October 13, 2015 Share Posted October 13, 2015 Yes, the KP is due to AppleIntelBDWGraphicsFrameBuffer requiring DVMT pre-allocated memory in BIOS set to 64mb or higher Excellent! Is there a benefit to going beyond 96MB? I have 16GB of RAM and I don't mind sacrificing some more for added performance. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 13, 2015 Moderators Share Posted October 13, 2015 No benefits that I could see, but could cause KP for some Brands/Models. Link to comment Share on other sites More sharing options...
dstrukt Posted October 13, 2015 Share Posted October 13, 2015 Changed DVMT and verified the changes. Booting from USB now just hangs at the Apple logo and the progress bar does not move Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 13, 2015 Moderators Share Posted October 13, 2015 Make sure you had change 2 variables to 0x3 0x15b and 0x15C When you get to the Clover both menu, hit the space bar and select boot without cache. See where it's hanging and post it here. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted October 13, 2015 Moderators Share Posted October 13, 2015 That's a Clover issue with OsxAptioFixDrv-64.efi. What version of Clover are you running? Link to comment Share on other sites More sharing options...
dstrukt Posted October 13, 2015 Share Posted October 13, 2015 2.3k r3270 I've tried installing r3280 (from http://sourceforge.net/projects/cloverefiboot (chameleon, stolen and rebranded)/ ) but Clover says it's not compatible and fails to install on my rMBP.
