It requires more power than the two 6-pin cables (you would have to buy at least one assuming you have one already).

check out the 7970 which I assume is more commonly being used — though still only a small handful % of users.

Cards that need an 8-pin power cable often can mean needing a small but extra 450W PSU.

The XFX 7970 working out of the box?

All these cards require flashing for boot screen and full for full 5GT/s linkspeed they require flash and removal of a small resistor. http://forums.macrumors.com/showthread.php?t=1547340

You can go for a 6 pin to 8 pin adapter for these cards. A lot of people report that these cards run fine like that and won’t damage your Mac’s power supply or mainboard.

To be on the safe side you could do this:

— get 2 x SATA power to 1 x 6 pin power adapter

— 2 x 6 pin to 1 x 8 pin power

This way you will get full power requirements for these cards without going over the specs of Mac Pro PSU and Mainboard power connections. But you will lose 2 x SATA ports on the board.

Visit netkas.org etc. for more information before you do any of this 😉

where i can find a procedure y files for prepare a Gtx 770 to work fine on my Mac Pro?

I got a XFX R9 280x Black OC addition. Could not get it to work in my 2009 mac pro. It comes with an 8 to two 6 pin cable. I also bought a 8 to 6 pin adapter. So far I have had no luck, I have a second video card installed so I can get the boot screen and get a system report. The fans spin on the new card but it never shows up in the report. I have been on netkas and searched around. Barefeats got a 280x from a different manufacturer using the Eight to six adapter and the other six to six. But that has not worked for me with this card, so I am returning it.😟

I new it was a bit of a test and it might not work. You can buy a flashed one from MACVIDCARDS on ebay, but its pricey compared to the stock card and there is only a slight speed bump according to barefeats having it flashed.

So back to the drawing board. The R9 is cheaper than the older 7970 but they are essentially the same card.

The black addition may be the reason it doesnt work and maybe the cheaper version would. don’t know.

Still wainting to here back from a few folks before I retun it.

Just thought I would share my experience so far.

What other gpu you said you have in there? I assume it does not use any extra power which would mean GT120 OEM likely.

Also — the assumpion is you have OS X version to support this card too (10.9.2+)?

Ideal would be to hook it up to a 450W external PSU $35 from Newegg or Amazon.

You can send the card to Macvidcards and have him handle flashing etc and maybe even test — but at least ask him . Then decide if you need to exchange it (or return outright).

Barefeats probably is using an added power supply or not?

Mar 18, 2014 10:16 AM

Hi Hatter, Barefeats used the internal power supply, and macvidcards states his flashed card works with two 6 pin cables, which I dont get but maybe he provides a 8 to 6 pin modded cable and aonther 6 pin to 6 pin. They run both run them off the internal power suplly.

I have emaild macvidcards about flashing it for me and about my issues, waiting to here back from him.

Also I have been testing it under 10.9.2 but no luck.

My other card in slot 2 is the ATi 2600xt which needs no power.

Mar 18, 2014 10:50 AM

Ah, yeah, have seen your post on Netkas.

There’s only two, no three possibilites, as far as I can see:

1. Your card is broken. Dead on arrival 😉

2. It doesn’t get enough power .

3. or it doesn’t detect power on one of the cables correctly.

So either your 6 pin to 8 pin adapter is not the right one. Not the right setup of power lines and grounds.

Or it doesn’t get enough power in, which should not be happening in Desktop / 2D only. It should at least boot up.

Be advised that, also a lot of people say they run their 280x / 7970 from internal power only, your are OVER the maximum the Mac Pro can safely supply. The Mac Pro gives you 1 x 75 from Slot, 2 x 75 Watt from 2 x 6 Pin on the board. Thats 225 Watts. The 280x can easily draw 250 Watts and spike to even more. The card is designer for 2 x 75 Watts = 150 Watts: 300 Watts.

The Mac Pro has the power lines as traces ON THE MAINBOARD. So if they overheat / fry: there goes your whole board. And I’ve already read that a couple of times from people. Or the Mac Pro just gives you the hard «shut down» as a safety measure.

I advise to either go for an external PSU, which you would have to hook up to internal power to make it switch on / switch of with Mac Pro.

Or, to get it to run safely with internal power, do it like this:

1. Get a 2 x 6 pin to 1 x 8 pin adapter to give the 8 pin port on the card the requires 150 Watts.

2 . Get a 2 x SATA two 1 x 6 pin adapter and connect to 2 SATA ports on the board. Gives you the 75 Watts for the 6 pin easily.

That way you’ll lose two SATA Ports, but you still have 4 in total for drives (Two Bays and 2 from the optical bay).

Enough power, no danger for motherboard. No external PSU needed.

What about AMD’s R9 Series (280x, 290x) on our Hackintoshes?. Further explanation.

inaki.mat

Now that Mavericks has been released I would like to talk about the possible compatibility of some AMD GPUs on a Hackintosh besides the FirePros that go with the new Mac Pro.

This GPUs are the R9 xxx Series for example the R9 280x and the 29 290X and in fact share many similarities with Mac Pro’s FirePro GPUs. I think this is very interesting since AMD R9 graphics cards retail at half price of Nvidias cards. This way it would be affordable to make a CrossFire configuration with these cards and double the performance of for example the GTX 780 getting to the level of the graphic power of a Mac Pro

I found a post where somebody finds similarity between R9 lineup (the R9 270x and the FirePro W7000 with the D300 from Mac Pro’s FirePro unreleased GPUs
http://www.overclock.net/t/1436253/. md-firepro-d500-dual-amd-firepro-d700-options

I extract the next paragraph from an article on extremetech.com that also points out some similarities between the same D300 Mac Pro’s FirePro graphics cards and other that are already released by AMD (http://www.extremetech.com/computing/169239-apples-new-mac-pro-december-3000)

We know that as not certain as all these may seem, (since both see similarities with different models but they are not 100% sure) both AMD and Nvidia reuse the same component across more than a single card. Now that said, do you guys think R9 GPUs could be compatible with Mavericks? since they share some features with the new Mac Pro’s GPUs

I would like to know more about this matter and know your opinion. To me this would be the real deal for my Hackintosh and if this is so I am sure many of you would be interested too. Lets hope AMD releases this new GPUs that have only be seen on the Mac Pro sooner or later if all of the above isn’t enough for a Mavericks compatibility on our Hackitoshes.

R9 280X problems (sapphire and asus)

zavidos

Hi everybody,
recently I bought a sapphire R9 280X dual-x and I try it in my hack, first I had problem immediately after:
boot0: GPT
boot0: test
boot0: test

with strange garbled text and solve the problem with chimera installation on EFI partition.

Then chimera boots but I see a black screen and not the desktop (but I can open itunes and listen music, without watching).
If I put the system in sleep with power button and then wake it, everything seems working but with poor performance.

Then I tried GraphicsEnabler=No and I can see the desktop but it is like one row of pixel is slightly shifted with respect to the upper and lower one, I can read text with some difficulties but it is horrible, I notice that if I unplug and replug the DVI connector everything come back to normality but with the same boot performance.

Then I tried the R9 280X ASUS DirectCu of a friend, and I had the same problem even if the asus was reported as working OOB, what can I try?

Total_Noob

Hello, Have you fixed your problems yet? There are various suggestions on this site like setting the Hack to a MacPro 5.1 also deleting AppleTyMCE Driver kext.

Let me know how you get on as I’m hoping to get a 280x as well.

No GPU acceleration: MacOS 10.12.3 + FCPX 10.3 + AMD R9 280x

Husta

I just noticed that my setup can obviously not make any use of GPU acceleration even though I have used known to work components. My Setup is:

HW:
Gigabyte GA-Z77-DS3H
Intel i7 3770K
Sapphire AMD R9 280x
SW:
MacOS Sierra 10.12.3
FCPX 10.3

Exporting video with FCPX literaly takes ages. In order to verify that the dGPU was used i had a look to the dGPU temperature during an export and realised that the temperature would stay at its idle temperature of 47°C. There was not a single rise in temperature while exporting.

I tried using the BruceX benchmark for FCPX next and it took 35sec to export the 10sec clip. When searching the web this should be more like 9-10sec when the dGPU was used. However there seem to be many people experiencing this problem with Sierra 10.12.3 and FCPX 10.3. Some of them reported that there export speeds with BruceX have dropped from 9sec to 30-30sec after the last FCPX update.

I tried to downgrade FCPX 10.3 to 10.2.2 and was able to enhance the encoding speed from 35sec -> 25sec. However that does not satisfy either since the GPU agains does not seem to use GPU acceleration (temp stays the same).

On Apples Website it looks like they have ditched support for the R9 280x with Sierra:
https://support.apple.com/en-us/HT202239

Does anyone else have these problems? Any idea what I could do about it?
Thank you very much in advance

Flashing R9 280X for boot screens/PCI System Information

Mr. Zarniwoop

macrumors 6502a

I have a 2006 Mac Pro running Yosemite (thanks Pike!) and now on to «fit and finish» nits to make it work.

I got an MSI R9 280X Gaming 3GB video card, and it worked great out-of-the-box, but I wanted to get boot screens and get it recognized in the PCI section of System Information. I chose this card because it’s not too expensive, and clearly others have had good compatibility experiences in Mac Pros with Mavericks and Yosemite.

So, I read the AMD EFI firmware thread on netkas for a general understanding, grabbed Rominator’s 7970 EBC firmware, and used them to make my own MSI EBC Mac ROM.

Works. Dive in. The water’s fine. Boot screens and all.

Next step: figuring out how to change the «AMD Radeon HD 7970» text string in System Information.

Glad you liked the EFI.

If you look carefully over there, there are also R9 280X versions of same thing.

Open 7950mac.efi in the «bundle» folder that you downloaded using a Hex Editor. Search for a text string which contains either 7970 or 7950. Then replace it with whatever name you want your card to appear on System Profiler. Redo the whole process of creating a Mac rom for your card and reflash. I have a Gigagyte R9 280X V.2 and was able to get it done this way. There may be another procedure to accomplish the same goal though.

The Gigabyte card has been working wonderful for me. My 5,1 is able to run 4 monitors simultaneously (3 22″ LCDs and 1 82″ TV @ 1920×1080). The temp never got above 70 C.

Thanks much for this helpful info!

Apologies if I missed it, but does this EFI also enable PCIe 2.0?

Or is that still a resistor removal trick?

Cheers + Thanks again

Doh sorry, I was staring at the signature in the post above my reply while writing.

Thanks all the same.

what is the power requirements for that? I am looking at the xfx double d r9 280a, but i can’t seem to find if i will need an additional power supply and what the damn thing consumes for power.

I used ATI Winflash in Windows 7 (using Boot Camp).

Some benchmarks of my EBC-flashed MSI Radeon R9 280X Gaming 3G in my 2006 Mac Pro attached. I tried to duplicate a few of the benchmark tests from Bare Feats when they originally tested the Mac 7950 in a ‘Mid 2010’ Mac Pro 3.33GHz Hex-Core, although using Yosemite with Pike’s boot loader:

• PART ONE: Sapphire Radeon HD 7950 versus other Mac Pro GPUs
• PART DEUX: Sapphire Radeon HD 7950 versus other Mac Pro GPUs

My assumption was that on-card GPU tests would likely be faster, but likely not when relying on my slower 5300 series CPUs, 667MHz memory, or 2.5 GT/s bandwidth PCIe 1.1. That seems to be generally true. All in all, not bad considering not many eight-year-old machines can Geekbench around 11000.

I didn’t really try to optimize very much, leaving it in 2560×1600 resolution and with iStat Menus running and some other background processes. I did use Quartz Debug set to Force QuartzGL and Beam Sync Disable.
