Graphic card Power Color PCS+ Radeon R9 270X

 

Ok, I am proud owner of mentioned video card and as such, I'm trying to figure how to fix few minor bugs. The card is working Oob, but the problem is in the fact that the system is not assigning proper framebuffer, which might case low performances in certain situations. Instead of this, card is using default one (ATY,AMD,RadeonFramebuffer) so that’s the reason why is not signed properly (AMD Radeon HD 7xxx 2048 MB). The latest Chameleon bootloader doesn't have proper solution for these video cards, because assigning framebuffer from chameleon plist will basically do noting. This means that commands such as: GraphicsEnabler=No, AtiConfig=Hamachi and AtiPorts=4, will not do the job. I don't know why but this is the fact for now. It looks that this little issue does not degrading performances noticeable, however I wouldn’t mine to fix this if I can.

 

So, logically this brings us to the DSDT injector fix…

 

Now here is the catch. When I insert code in my DSDT.aml file and I boot, all I have is the black screen when I enter OS X!

 

The first thing that is cross my mind is a thought that I was probably assigned wrong FB, so I was try to apply all others extracted from ATY personality dump, which is presented in ATI7000Controller.kext.

But nothing was changed.

 

After some time, I was notice that when I boot in OS X, the display actually is not going in to sleep mode, which it should when the wrong FB is applied, but on the contrary it stays on, beside the fact that the picture is completely black. So I was apply sleep fix by pressing power button and basically force computer to go in sleep mode, and voila, that was do the trick, because when I was wake from sleep my computer, the picture is also back and everything seems to be fine. This also means that assigned framebuffer (Hamachi) is used properly, and in "About this Mac", I have a valid info which I was inserted previously in my DSDT file (check pictures).

 

So the only thing basically which is needed here is fix for black screen on boot!

 

I presume that something is missing in DSDT code, but I’m not sure what precisely that might be, so I will leave here all my files and resources, and if anyone here have an idea how to fix this booting problem, well just let me know.

 

BTW, if anyone wants to know, Mavericks is booting w/o any problems, but ML needs kext patching (device id fix / 68101002) and white screen fix

Thanks. However this blackout issue is really annoying, so it would be nice if we find a proper fix for that.

 

And here is the full ATY personality dump from 10.9 Mavericks...

Here are the files you asked + rom file too...

 

BTW, Redsock BIOS decoder dump is showing 5 connectors, which is interesting… hmm... That question mark on 4th connector is looking a bit odd to me…

@Vlada.

Thank you for the rom file. This new card is in my wish list hence my interest. In the meanwhile have been fiddling the frame buffers for my HD7770 trying to get two displays going. Found Dashimaki most suitable. as the sense ids (from radeon_bios_decode) are closely related. However after many futile attempts now settled with one display on the hdmi connector cos using hdmi audio. Everything works fine with this setup.

Even with the DisplayPort nearly all is well, but cannot wake up from sleep - something about pin 20 and the DP-DP cable. And, in my case without DSDT injection, the DVI connector works well with Buri and GE on. 

With the default Radeon FB both displays work but again wake from sleep failure.

You may want to rearrange your preferred frame buffers similar to the personalities when the default frame buffers is loaded. If you only used the DVI connection arrange to load it @0, or @1 similar to the default RadeonFB. (i.e. rearrange the port hierarchy). This may overcome your black screen but need check wake from sleep.

Best of luck.

OK, I was made further tests. Till now, I was figured that the card is working with 3 framebuffers (Aji, Futomaki and Hamachi). Sadly, HDMI doesn't work with any injected Framebuffers, but it works with default one (ATY,AMD,RadeonFrambuffer@0)

 

If I understood well all numbers, this should be correct:

 

Connector-type number for (DVI) is 0x4

Connector-type number for (HDMI) is 0x800

 

With DSDT injector display is reported on third connector (ATY,Hamachi@2), and in situation where DSDT injector is not used it is on first (ATY,AMD,RadeonFrambuffer@0)

 

Those are basically obvious differences.

 

I could rearrange this but if I remember correct that will require AMD7000Controller.kext patching via some hexeditor, which I’m really trying to avoid.

 

In both cases sleep is working properly, which is good thing.

 

I was made also, OpenGL tests in Cinebench. Mavericks reports this card as FirePro D300, but ML 10.8.5 reports it as Pitcairn Unknown model. The better score is in ML 10.8.5, probably because it detects card properly. 

 

I really hope that the future OSX updates will fix this issue…

Final conclusions:

 

As I was previously mentioned, this GPU is working Oob, but it using default AMD,RadeonFramebuffer, which obviously isn't the best solution. However after further testing, it seems that this doesn't affect performances at all, or if it does, well then that is totally insignificant. Per example, a difference in Cinebench R15 is exactly 1FPS.

 

Although I didn’t have any troubles with my card, I was tried to assign some Framebuffer from the AMD7000Controller list, so that I can sign this video card properly. After 2 day testing it seems that the card can use 3 FrameBuffers and those are: Aji, Futomaki and Hamachi. Aji and Hamachi are same in the code, so I decide to take a chance with Futomaki, because is easer to find it via hex editor. Final result considers DSDT injector in combination with patched AMD7000Controller.kext with next values:

 

Personality: Futomaki

ConnectorInfo count in decimal: 4

Disk offset in decimal 663056

 

00  04  00  00  04  03  00  00  00  01  01  00  12  04  04  01

00  04  00  00  04  03  00  00  00  01  02  00  22  05  05  02

04  00  00  00  14  02  00  00  00  01  03  00  00  00  06  06

00  08  00  00  04  02  00  00  00  01  04  00  11  02  01  03

 

is modified with next values:

 

04  00  00  00  14  00  00  00  00  01  00  00  11  02  05  05

00  08  00  00  04  02  00  00  00  01  00  00  22  05  02  03

00  04  00  00  04  03  00  00  00  01  00  00  12  04  01  01

00  02  00  00  04  02  00  00  00  01  00  00  10  00  03  06

 

First connector is assigned to DVIDL, second to HDMI, third to DP and last one is to DVISL.

 

So in this combination, blackout issue is eliminated and HDMI is fully operational. It works in single and dual variations, which mean that you can plugin in DVI or HDMI separately, and both at the same time. Unfortunately DP cable I don't have so I wasn't been able to test it, but I believe that DVIDL + HDMI combination will be more than enough for most people.

 

I don't know is there any differences in code with others R9 270X graphic cards, but if you have this card (dev-id 6810) and you experience problems in regular work, well I think that you can try this fix or solution…

 

This fix is also "must have" for ML, because Radeon R9 270X is not working by default under OS X 10.8.5. 

 

Hopefully, Apple will fully support this GPU with next system update.

 

 

Best to all of you :D

Latest solution considers modified code injected via Clover, or other words this method represents a permanent solution that does not depend from the future system upgrades. If you want to use it or you still have issues with solution presented here, check this topic: 

 

[HOW TO] Modification of AMD FB + Clover injection

 

----------------------------------------------------------------------------------------

 

I was made a driver pack for those who don't want to mess with DSDT. So this is solution which doesn't require DSDT.aml at all. This pack using modified ATY Init.kext as injector that supports R9 270X GPU with 6810 device id and R9 270 GPU with 6811 device id.
 
You can download it from here:  AMD Radeon R9 270 Series

 

Or if you want to do it by your self you can use this bin patch from terminal:

sudo perl -pi -e 's|\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x01\x01\x12\x04\x04\x01\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x02\x01\x22\x05\x05\x02\x04\x00\x00\x00\x14\x02\x00\x00\x00\x01\x03\x00\x00\x00\x06\x06\x00\x08\x00\x00\x04\x02\x00\x00\x00\x01\x04\x00\x11\x02\x01\x03|\x04\x00\x00\x00\x14\x02\x00\x00\x00\x01\x00\x00\x11\x02\x05\x05\x00\x08\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x22\x05\x02\x03\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x00\x00\x12\x04\x01\x01\x00\x02\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x10\x00\x03\x06|g' /System/Library/Extensions/AMD7000Controller.kext/Contents/MacOS/AMD7000Controller

[R9 270 users will need to manually insert device id number 0x68111002 in to info.plist files inside AMD7000Controller.kext & AMDRadeon4000X.kext]

 

And for those who prefer to use DSDT injector instead of ATYinjector.kext from the pack, here is a patch:

Under Device (PEGP) put this patch:

Device (GFX0)
{
Name (_ADR, Zero)
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x18)
{
"AAPL,slot-name",
Buffer (0x07)
{
"Slot-1"
},

"@0,name",
Buffer (0x1A)
{
"ATY,Futomaki"
},

"@1,name",
Buffer (0x1A)
{

},

"@2,name",
Buffer (0x1A)
{

{
"113-R27FD-001"
},

"ATY,Copyright",
Buffer (0x33)
{

Hi Vlada, 

 

I'm from Brazil and apologize for my English.
 
Very good job for their lucky owners of R9 series 270x.
 
It turns out that previously I had a HD6770, running perfectly on my hackintosh. All perfectly fine. When googled and saw several people commenting that the R9 x270 and X280 worked oob. I thought, there is my new VGA.
 
Happily bought and installed. I realized that probably the kext that I had the HD6770 might be holding something, because I did everything. Including this your last installation. In no time the Mavericks failed to start or have a white or black screen. He just goes out the resolution and information as unknown and 3mb.
 
What I need to clean? have any idea what can I do? I've tried with several things chamelon wizard with startup settings. GraphicsEnabler = No and Yes
 
My VGA is a APPHIRE DUAL-X R9 270X 2GB GDDR5 OC WITH BOOST
 
Any idea?

Previous settings shouldn't affect enabling of R9 270X graphics, even if you used patched AMD6000Controller.kext for mentioned HD6670, because R9 270X is using other kext ( AMD7000Controller.kext ). I really don't have a clue in this very moment why you have such problem, but you should check which device id number is using your video card.

Ah, this explains everything. Your card is not 270X but 270. So that's the reason why it's not working. Device id for your card is 6811, but inserting mentioned device id in AMD7000Controller.kext is not enough. You will also need DSDT injector applied, and even then there is no any guaranties...

 

All in all, you will need to do next:

 

1. You'll need to insert device id (68111002) in modified AMD7000Controller.kext which you can download from here, and install it.

2. You'll need to insert DSDT injector fix in your DSDT.aml file

 

[EDIT]

 

3. You can use now also AMD Radeon R9 200X Series pack which you can download from upper link. 

 

Best of luck ;)

in AMD7000Controller.kext was easy... but with the DSDT injector I no have ideia. I´ll try to change my video card, because she was sold like a 270x Video card.  :( 

 

Is an 270 OC edition with dual fan, but i think that video card is more weak than 270x.

Well, I guess that I can be little generous. So here they are, ATY init.kext, AMDRadeonX4000.kext & AMD700Controller.kext that supports device id 6810 & 6811. 

 

So just install these and let me know will it work. ;)

 

[EDIT]

 

Obsolete kexts are deleted...

My chamaleon have no flags for video.

 

But, I really appreciate your generosity and help. But nothing happened and now I do not even know why. If you want to take a vacation here in Brazil, you are my guest. I live in Rio de Janeiro!

 

Thank you so much by trying.

Soooo.... I change my video card. I get this.

 

http://www.msi.com/product/vga/R9-270X-GAMING-2G.html

 

A genuine 270X with OC and a BIG X and the device id is really 6810.

 

But the Mavericks dont start anymore. I'll post a photo with my phone. I try to start with -v -f -x UseKernelCache=No. and no video flags.

 

I think that if I enter in the system and use your easy install. I´ll have a great chance of everything working.

 

PS. is a {censored} english, i know :D

Enter BIOS, and disable from there internal graphics (IGPU). Switch to PEG and then try again… I had the similar problem when I was plugged my GPU. 

 

If that doesn't help, you'll need to try with other boot loader. Chameleon r2266 is working, latest Clover too.

 

P.S.

 

As for your english, don't worry… I rather say that is ok, since we understand each other… ;)

 

Oh btw, according to this topic it seems that R9 270 GPU-s with 6811 device id, also works… I was used the same method and I really don't know why it didn't work in your case.
