[Guide] Getting XFX HD6850 connectors to work

Lordadmiral Drake · February 5, 2012

My card is now correctly identified as HD6850 and DVD player is working. Can't test outputs though as my only monitor used VGA via an DVI-VGA adapter

cristian arenas · February 6, 2012

Thanks, what wonderfull post man!

really great job! I gonna try this after.

I want to share your job in mi facebk.

BALDY_MAN · February 6, 2012

THANK YOU VERY MUTCH

I just tried your 6000 Ati controller kext. with my sapphire.HD6870. and i now have two monitors working from dvi1 and dvi2 Dvd player works

I apologize for not responding earlier. I got an intership on early January and things have been crazy for me right now.

After reading everything and seeing the posts you all have made I see that most of you have got it working, I'm really glad for you.

If you can (and want to) please post your fixed kexts (and/or final connector profiles) for others to download.

Nothing beats having a good database of previously edited kexts for different models/configurations/etc.

@lox72 Does the screen always flicker or just in some random moments? How many and which outputs do you have connected when it happens? Could be a link/encoder problem.

@billdlv Thanks to your post I am now aware of the new redsock_bios_decode tool. I have added the link to the tutorial. It should prove to be useful to many.

Yeah I can post it to my thread. The redsock decode tool helped a lot but the one thing it was wrong was for the transmit for the DVI-I port. That combined with the hotplug ID numbers can make for a lot of combinations. It's too bad there is not a way to determine those.

Update: resolved to my satisfaction, details in post #33

Wonderful walkthrough and I've made some real progress on getting my Sapphire 6870 into a proper state.

tl;dr:

I'm getting full acceleration now (thanks Alex and others!) but I often (while moving a window or just the pointer even) get "freezes" in the UI accompanied by a sudden spike in CPU utilization from the windowserver process. I can drag a window around and it will freeze for a moment or two and I see windowserver spike, probably to "catch up" -- it isn't being treated as a hang or a spin by the kernel.

I could really use another pair of eyes from someone more capable than myself.

My card is the 100314-3L model: there are four ports on it, [ DVI-Dual ] [ HDMI ] [ DP ] and then a lower [ DVI ] single-link port.

I was previously running with GraphicsConverter=No just to let me use both displays and get work done, but some software will crash or fail to launch correctly and now it's really starting to get to me that I haven't conquered this card yet.

I'm running 10.7.3 and I have started with Duckweed and have been hard at work crafting my own version of this personality. My system is a Sandy Bridge 1155 with an i7 and a Gigabyte Z68 UD3H-B3 using TonyMac's DSDT in the database.

My ideal criteria for success is to have two displays driven, one 24" LED @1080p and one 20" LCD @1440x900 using HDMI and the upper DVI port.

Since I'd like HDMI and the upper DVI port to work (I don't actually need dual-link DVI since that port is only driving a 20" LCD) I'm focusing my efforts on the first two, with the first line being my upper DVI port and the second line being the HDMI port.

I have managed to get the following as my Duckweed-derived personality so far:

Personality: Duckweed
ConnectorInfo count in decimal: 4
Disk offset in decimal 176800

I believe my Sense IDs are correct (easy enough to get those from the bios decode tools, I dumped my bios using GPU-Z in Windows 7) and I think I have the right encoder and transmit values, I'm fuzzy on the HotPlug values I'm using or if it matters for my problem.

I've really learned a lot from this thread (and the pointers Alex links to in the OP) but I'm really hitting a wall with this freezy video thing.

Any assistance would be very appreciated by me, and my long-suffering spouse who has seen me digging around behind my desk more times than I'd like to admit to already

dzzh · February 12, 2012

Hello guys,

I also have a problem with a system freezing up for a couple of seconds which occurs about five times per minute. I have Sapphire HD 6870 videocard that has same outputs as Alex's XFX and the same offsets. I tried to use both the kext from Alex and the one I created based on the top post, but didn't manage to resolve the issue. Also, I tried to play with various values for encoder byte, it didn't help as well.

My intention is to make two DVI monitors working simultaneously, I did that but it's impossible to use the system with the freezes of this kind so any help will be highly appreciated to avoid them.

...

After some surfing here and there did manage to solve the problem by installing the kext from here http://www.insanelym...howtopic=275546 and adding AtiConfig=Gibba, AtiPorts=5 to the boot.plist. So far so good, everything works like a charm.

My Sapphire 4-port Duckweed 6870 100314-3L model with [ DVI-Dual ] [ HDMI ] [ DP ] and then a lower [ DVI ] single-link port is now working trouble-free with DVI-D and HDMI using the following values:

0000000	00  02  00  00  04  00  00  00  00  01  00  00  11  02  01  06	  // dvi-d  
0000010	00  08  00  00  00  02  00  00  00  01  00  00  22  05  06  04	  // hdmi  
0000020	00  04  00  00  04  03  00  00  00  01  00  00  12  04  04  01	  // dp	  
0000030	04  00  00  00  14  02  00  00  00  01  00  00  10  00  03  05	  // dvi-i	
0000040

I can't test the Display Port and I don't care about the other DVI port, but I'm happy now and these values I'm using for Trans/Encode have eliminated my stuttering and graphical hesitations. This has been a great learning experience for me.

ghostdex · February 14, 2012

My MSI R6850 Cyclone Power has identical values so I used the kext from Alex and HDMI is now enabled with Duckweed framebuffer. Unfortunately the mouse/system freezes every 5-20 seconds so it isn't useable. Any Ideas to fix this freezing issue?

fffeee · February 14, 2012

As mentioned in this thread a few times, your Encoder values need to be adjusted.

alex_tzardea · February 15, 2012

Hi alex.i would love getting my card fully working,you made a pro tutorial here,good job! i have a problem though,the ati_personality 0.8 script will only give me 3 connectors info for each one (?!) or am i missing something?i have to say,i'm new to all this,so i may have done something wrong,yet,i tried to follow your steps carefully.My card is a XFX HD 6870 DisplayPort XXX Edition 687A-ZDFC, it has 2xDVI,2xMiniDisplayPorts,1xHDMI(so 5 connectors).My display is connected via top dvi (DVI-I),it's a 24" FullHD Display,it works,i have like 49-50 FPS in Cinebench, dvd player,steam,fullhd .mkv videos working,ecc.On bottom DVI (DVI-D),my screen will stay black,so it's not working.I want to add 2 other displays to my system,so i would try,before buying them, to patch a personality that would "do the job",as you did.Anyway,i'm on 10.7.3 x86_64,latest Chimera,that loads Duckweed as default FB.So before trying other FB to see how they behave,i wanted to check if i can understand the procedure to edit the personality.I followed your steps,i dumped my bios,i decoded it,i ran the ati_perl script,but the last one gives me a different output,so i'm already stuck -.- .

I hope you will take 2 minutes to reply to me,unfortunately i can't go any further at this point :wallbash:

This is wierd. I see you have 10.7.3. If I remember correctly it updated the drivers... Maybe the script is having trouble with the new drivers?

Anyway... I took a dump of the 10.7.2 kext and they seem to have the same offsets, so it theory it should work.

If it doesn't work then my recommendation is to get the 10.7.2 drivers and work with those.

To be honest, I haven't updated my system yet so I wouldn't be able to help you any further.

Good luck.

Thanx! :weight_lift:

// LE:

Opening ATI6000Controller i noticed that values were different than those you got on 10.7.2,so i re-run the ati_perl_script and MAGIC:this time outputs the correct info(maybe cause i rebooted the system these days).This is what i get:

Good luck with the editing!

I had to change my HDMI HotPlug ID to 06, not the Encoder to solve the freezing problem.

HDMI and DVI are both working, second DVI not. I can't check DisplayPort.

Who knows something about MVAD parameters and saved-config for Ati cards?

Thanks for the good guide (rewritten). After I read this topic, I thought to get all working connectors of my PowerColor HD6870 (AX6870 1GBD5-2DH) last night. Finally, I got all connectors today.

I looked personalities and got Gibba that is similar to Duckweed. Gibba has 5 connectors while Duckweed has 4 connectors. I booted with AtiConfig=Gibba and got DVI 1 and HDMI working. So, I tried to change as following

Then, I could use combination of either DVI 1 + DVI 2 + DP 1 + DP 2 or DVI 1 + HDMI + DP 1 + DP 2 as maximum four connectors. Also, I could use DVI 1 + DVI 2 or DP 1 + DVI 2 or DP 2 + DVI 2, for example. All connectors can be plugged and unplugged (detectable).

Note: DVI 2 will be disable when HDMI is active. I was using HexEdit to edit the personality. Using PowerColor active mini DisplayPort / DisplayPort to DVI adaptors.

Monib · March 23, 2012

Thanks man! This worked with my GA-Z68P-UD3H-B3 F10, and Gigabyte HD 6850. I don't see any problems yet. Haven't checked HDMI/DP, but Dual DVI works now.

Narayana · March 30, 2012

Has anyone used this method to get a Sapphire 6850 1GB properly? If so, would you mind uploading your ATI6000Controller? It would be of incredible help. Thanks!

fffeee · April 7, 2012

I'm not rocking a 6850 but we may have the same port layout (hdmi/dvi x 2/dp) so my edits may be helpful while you make your own.

My Sapphire 6870

kext and documentation @ https://s3.amazonaws.com/20120406-hac-6870/sapphire-6870-hdmi-2x-dvi-dp-10.7.3.zip

detached signature @ https://s3.amazonaws.com/20120406-hac-6870/sapphire-6870-hdmi-2x-dvi-dp-10.7.3.zip.sig

My (included) README.md follows.

# Sapphire 6870 100314-3L

This is an edited ATI6000Controller kext with a new Duckweed personality.

It activates HDMI and the dual-link DVI port on the top of the card, and probably (maybe) activates the lower DVI port as well.

This card has the following layout:

[ DVI-D ] [ HDMI ] [ DP ]
[ DVI-S ]

This was created using the resources and information contained in an InsanelyMac post by [Alexander Martinez](http://www.insanelym...pic=273937&st=0)

I don't use Display Port so I don't know if that works correctly or not.

Thank you fffeee my sapphire 6870 is now waking after sleep with HDMI. You saved me a load of time.

Hi everbody,

I am reading along time here but the first time post

I have a new system with;

Gigabyte Z68AP-D3 F3 Bios

Intel Corei5-2500k

XFX HD 6850 1GB ZCFC

Corsair Force Series GT 60gb SSD

Corsair 8 GB Vengeance Ram

Corsair Carbide Series 400R

Corsair Enthusiast Series™ TX650M

Pionner DVD Rom

I installed the Lion 10.7.3 on my system.Everything works great except my Video Card.I have xfx 6850 zcfc but it did not work properly.

Lion did not recognize xfx.I get only 1024* resolution on my Samsung 32" hdtv.I use dvi port to connect.

I have already read the Alex's article about xfx 6850s.But i am a new user on mac systems so i am not as pro. as you.

When i am using mobo's onboard graphics everythings work perfect.

And i go to system report>display> i see two graphics option; one is my xfx (Atı amd 6850)

other is intel hd 3000

So lion see my xfx 6850 but dont allow to use it.

What can i do ? Any solutions about my problem.

I only reach to desktop -x GraphicsEnabler=No thats all.

when trying -v i get Slot-1 error

I used ##### Method for Installation

(Sorry about my english)

Go to bios / advanced bios features / onboard vga and select enable if no ext peg. You might have to select your "init display first" to pci or pcie x16 if that doesn't work.

The Edge3000 · April 14, 2012

Thanks, fffeee! Your modified Duckweed is just what I needed to get both DVI ports working on my Gigabyte 6870! Looks like you can't do HDMI + DVI like with vanilla Duckweed in addition to this; you gotta pick one. Glad to finally be able to let my computer sleep without needing to turn off my HDMI monitor to prevent seeing the NO SIGNAL INPUT screen!

PoisonDrop · April 15, 2012

Just thought this may help someone...

I have this card: http://www.gigabyte.us/products/product-page.aspx?pid=3630#ov

It is a Gigabyte 6850 OC. The connectors are the same as the XFX in this guide. After booting Windows and doing the dump, I realized that EVERYTHING else is the same too. Output from the bios decoder was identicle. I am using Mountain Lion...just edited the new version of the driver with the final result at the end of the first post. Works flawlessly, even triple monitors with an active adapter.

If anyone is wondering, Mountain Lion brought a revision to the ATI kexts, which is the only reason I had to edit anything. If you have regular Lion, the kext provided by the OP will probably work just fine.

EDIT: On another note, Chameleon loads Bulrushes for this card by default, even though it only has 4 connectors. I had to use AtiConfig to load the correct fb. And if the DP screen looks funny on boot, adding a Graphics Mode to the boot plist will fix it.
