Radeon HD 6450 gives me black screen and reboot, cant see installation screen

[PHVME]

I used UniBeast to make a Sierra Stick. But everytime the apple logo shows up, my screen flickers after the loading bar is halfway through and reboots. My radeon hd 6450 should work oob so I dont know whats the issue here. I‘ve tried everything. Lilu and whatevergreen doesnt do anything.

My pc is a hp compaq 8200 elite with an i7 2600 and 8gb of ram.

Please help.

Hit the space bar once at clover boot screen and select verbose, don’t reboot on panic, keep symbols and take a pic.

It seems theres no kernel panic.

I checked those boxes you said but it restarts. The last line I could read is the same last line I can read with my other GT710. But the GT shows the login screen, the 6450 restarts.

My clover graphics menu looks like this, theres always bulrush automatic. Normal? I leaved it blank but same result:

No you need to use the Pithecia Framebuffer with Inject ATI=True. Well that's what I use for my two HD6450 cards.
