What version of Clover? Nightly builds are not the best versions to use so stick with official releases if you aren't.
When I was setting up a testing Hackintosh a few weeks back I had strange problems using the absolute "latest" Clover but when I reverted to r2795 all worked well.
Use this parameters for Intel HD 4600:Thank you for the kind replay i am going to test it. The another problem i detect now is flickering in my HDMI monitor Dell S2240L
when os loading when it reached white screen there only display a Grainy screen about 10-15 seconds then the desktop appears. I am a fresh face in clover

Thanks will test it. I am using my old AMD HD 4670 with my build and 21.5 monitors 2 samsung and one dell. Dell is used with MB's HDMI then other 2 from AMD All these three are working correctly with Chimera. I prefer Clover its UEFI support and fast booting andn more vanilla install.
