Someone could explain me how to correct config Sapphire HD 6870 with clover bootloader ?

This card is detect by system as "AMD Radeon HD 6xxx 1024 MB".

I use only HDMI port.

When I active "inject ATI" system boot correctly but I have a black screen.

The detailed config is in my signature.

Find a similar card,and by similar I mean,one that uses the same framebuffer, and emulate it, "impersonnate" it with fakeid in clover's config.plist

I have a Sapphire 6870 in my Hack.

 

HDMI video is fine. Excerpt from my Clover config.plist file:

Sapphire HD6870 supported natively:

config.plist/Graphics/

Inject/ATI/YES

FBName/Duckweed

 

This may not work as you expect — the Sapphire 6870 I have is DVI-D, DVI, HDMI and DP and only one or two of the ports will work with that personality. I previously had to do kext edits to get DVI-D and HDMI working together, it's possible that @gekho21's connectors patch addresses that.

 

Ninja edit: I just tested it out and it will send a signal to both DVI ports on my Sapphire 6870, but the DVI-D port isn't presenting itself as dual-link and will only drive a 30" Cinema Display at 1280x800; the sense ports are also incorrect because they're both mapped to the DVI port so both ports detect active state by virtue of one being plugged in so if you disconnect one or both and plug them back in the displays and the windowserver get very confused — using just the Duckweed personality definition in Clover works the same way it used to; DVI-D works great but DVI is dead and HDMI is glitchy and causes stuttering of the UI when active occasionally. 

 

The Sapphire non-reference cards are not on my list of future purchases ever, I've been burned twice by them with a 5770 and now a 6870 (which is what prompted me to give up and get a GTX 760 in the first place).

Duckweed works native for my Sapphire 6870 Vapor X, same connectors, plus an additional DP, all working.  Your 6870 requires a Duckweed framebuffer edit as noted.  I had success with Sapphire 5570/Eulemur*, 5780/Uakari, 6670/Muskgrass, 6870/Duckweed and 7750/Dashimaki* (* framebuffer edits required).  Nvidia framebuffer configuration is far superior to AMD and Intel.

Hello, I'm reactivating this thread because I also have problems with my Radeon HD6870. Mine has 5 ports:

 

1x DVI-I

1x DVI-D

1x HDMI

2x Mini-DP

 

I have full resolution, Dual-Monitor, CE/CI/Rotation and everything, but the graphics accelerator won't start - the usual

 

**GPU Hardware VM diabled - (multispace: disabled, page tables updated with DMA: disabled

 

appears while booting. I tried various methods, after entering Duckweed as Framebuffer and a memory value, I got 7 MB VMEM and everything was slow as hell, no QE/CI anymore. Now I tested the patching tables from gekho21's info.plist in Clover, still no success. These kexts are loaded:

 

AMD6000Controller.kext

AMDFramebuffer.kext

AMDRadeonX3000Controller.kext

AMDRadeon.kext

 

All kexts have to be loaded, otherwise the card won't work. But none of these have a 'Duckweed' framebuffer entry, the AMDRadeonX3000Controller.kext has my card ID 0x6738 listed in the 'Barts' framebuffer entry.

 

In Snow Leopard my HD6870 is completely working with a modified kext and ATY_Init.kext. The main result appears in daily use - Xbench's GUI score are 62-66 in Yosemite and nearly 600 in Snow Leopard. And you'll notice the speed difference.

 

I would appreaciate some help, because this is my LAST problem to get a fully working Yosemite problem - and this is the last reason why I can't switch from my 2008 installed Leopard 10.5.8 on my AMD Opteron 185 to my Core i7.

 

Greets, naquaada.

Hi and thanks for this, I followed that exactly in my config.plist but I only get DVI output. No HDMI video out. This gives some color lines flickering at apple logo boot startup.

 

What else I can do or check for getting HDMI video output?

 

I am on El Capitan 10.11.2 and clover 

GIGABYTE GA-Z68MA-D2H-B3

AMD Radeon HD 6870

 

Thanks!

So mine HDMI doesn't work too. It detects second display (first mine is DisplayPort), like everything fine, but HDMI display says there is no signal =( 

Can someone help me?
