R9 Nano

Whether there is for R9 290X special Apple vBios? 

I used to run my 290 (40cu) with 390X memory controller init & tighter timings! I think it was clocked at 1130/1500 or something like that.... It did Luxmark @~18k!

290x* you mean send me that bios please

No, it was just a 290 with 40cus vs 290x with 44cus! :)

Reference card with Elpida's ram, a waterblock modded to a Antec Kuhler 650 AIO and 0,95V rail modded to higher voltage (to stop the screen going black & blinking).

Has anyone tried the R9 Nano/other modern AMD cards with a 5k Display? Be curious to see if Apple's native dual cable 5k support works. Probably requires the SMBios to be set to a model that supports dual cable 5k (MacPro6,1, etc)

I don't think anyone has seen 5K with AMD graphics on a Hackintosh so far. Rominator/MacVidCards (@netkas.org) recently tested it with a RX 480 (maybe also R9 Nano), but it didn't work.

Same thing B0 67 -> B5 67

 

Flash it to the card and you'll lose boot screen but it'll work with Sierra.

 

 

Okras, little question... say I stick two cards into the machine (either two nano/fury/x480/whatever), and I modify only one of the cards bios, will do that do the trick ? one being initialised by OSX, thus fixing the black screen problem, and leaving the other bios unmodified, so if I need to access bios or another OS I can just plug the screens on that one ?

 

If this work, will the unmodified one show up in OSX ? I need dual GPU for computing (Resolve and such)...

 

My Titan 1st gen is dying and I need to replace it with something... reluctant to leave the OSX platform, but these are my last efforts.

 

Thank you for your discoveries and hard work.

In a word, no. My mobo only tries to init the first/uppermost card, so I can leave the other card unmodded. I just flip the switch on the upper one and I get boot screen.

Sorry my dumb question... what do you mean by "flip the switch" ?

 

And wasn't totally clear : No two cards won't work on OSX ?

 

Regarding the card initialisation, thats what I understood, only the one in 1st PCI slot will be init. but does that mean the second one then isn't usable ?

No, everything works. Just need to flip the vbios select switch (yes, a physical switch) on the cards edge, if I need access to boot screen. Most, if not all, AMD gpus have two flash chips and a switch to choose which to use. :)

Ohhhh I see... didn't knew this about the AMD GPUs (dual bios thing), pretty cool... guess the switch is accessible form outside the cooling casing right ?

 

If you had to recommend between NANO/FURY/x480 what would it be ? knowing that now a lot of progress has been done now... main usage would be Adobe CC suite / Resolve Grading / Nuke Compositing. I would be purchasing at least two cards...

 

Since now almost everything is OpenCL optimised under OSX and the complete lack of further support from Nvidia at the moment I'm willing to take the dive.

 

Oh and thank you for the clarifications... really useful.

those are the device ids in hex, changing them make the gpu's  EFI in uninitialized state ( not only just EFI you may to consult gpgpu programmer to confirm this) , thus when the driver on osx loads it initializes the gpu... as in real macs. also this will make your 290X works 100% with sleep and wake. the only cons of this method, you get no screen output, also you won't be able to go to windows or linux if you're on a multiboot installations, a work around is to flip the vBIOS switch to the other rom so you can get screen output... 

 

beaware: doing this method of BIOS patching may bricks your card or get it out of warranty (to any gpu else not just r9s).

Which loader do you use? Clover?

Macs have graphics drivers built in firmware and are initiated on boot.

That's correct but not with non-apple cards which it doesn't have this firmware in them, So the result when you put non-apple gpu you boot to black screen till the card is initiated :)

All this is doing is replacing the device id in the GOP section of the firmware, doesn't make any sense at all why it would allow Sierra to boot without iGPU enabled. Maybe the way Clover is initializing the GOP section of the rom.

It just prevents the mobo's bios from loading the vbios on boot! Effectively the same as booting with iGPU as primary -> amd vbios not loaded.

Sorry, I wasn't referring to black screen on boot at all. Your statement was misleading in saying that the graphics were started by a driver after boot in mac like it would be for a pc or linux and thats not the case.

What do you mean?

what i mean is when gaming say i open up nxt runescape the entire system will crash and if i open up tomb raider it crashes i can't run any games now it was a good fix but sadly had major issues
