wujek_bogdan Posted October 11, 2015 Share Posted October 11, 2015 At the moment i'm running 4K@60Hz @ R9 280X, but because of bad news about AMD cards on El Capitan I'm about to buy Nvidia card, probably GTX 960. Can anybody confirm that 4K works fine at 60Hz under GTX 960 (Nvidia web drivers ofc). Specs: iMac14,2, Asrock Z87 Pro4, i7-4790k, 16GB DDR3@1600. Clover + SSDT generate with ssdtPRGen.sh. Thanks in advance. Link to comment Share on other sites More sharing options...

wujek_bogdan Posted October 11, 2015 Author Share Posted October 11, 2015 Thanks. I have heard that GTX 9xx works in 4K@60Hz mode only if SMBIOS is set to macmini6,2 or MacPro3,1 (and the linked topic confirms that). I have a Haswell processor so I've set SMBIOS to iMac14,2 which is a proper setting for Haswell. Are there any side effects after changing SMBIOS to macmini6,2 or MacPro3,1? I'm worried about power management. I do not use Clover to generate SSDT. I have generated SSDT with ssdtPRGen.sh script. Link to comment Share on other sites More sharing options...
wujek_bogdan Posted October 26, 2015 Author Share Posted October 26, 2015 OK I've found an answer. It depends on monitor. SST monitors works fine OOTB (so i can keep iMac14,2 SMBIOS). MST monitors works only if SMBIOS is set to macmini6,2 or MacPro3,1. Of course nvidia drivers have to be installed. Link to comment Share on other sites More sharing options...
