Please help!

 

I have a Gigabyte GA-Z77X-UP7, 3770k with intel 4000 integrated graphics. I've installed Clover and everything works great. I can boot up with integrated graphics and it recognizes everything. I've installed my PowerColor AXR7 (http://www.newegg.co...N82E16814131575) into PCIe slot 1 and everything reads properly for the most part. I've rebooted with integrated graphics and the system report shows AMD Radeon HD 7xxx with Device ID as 0x683f. When in the Clover boot loader, the graphics submenu reads the card as a 7750, which my research shows that the card I have is just a rebadge of the 7750 based on this video here ).'>() .

 

My problem comes when I try to boot from the R7 250. Under some conditions, when connecting my monitor directly to the R7, my computer will load for a bit and then restart itself, stuck in a constant loop. Under other conditions, I can get it to actually boot all the way through but the screen will lose signal / go black. I know this boots all the way through because I left a video playing before restarting and when it boots, the audio of the video continues. I've tried reconnecting the monitor, changing the ports, using the fake ID 0x683f1002 and the FB Futomaki. I've checked the inject ATI. Nothing seems to work. I've tried deleting the ATI and AMD kext from /system/library/extensions and connecting directly through the R7 works, as in there is picture, but the resolution is bad as if I was connected through the integrated graphics without intel injection. Can someone help me?

Did you make any progress on this? I'd like to use the same card in my hack, but I don't have integrated graphics to test with.
