If I typed 514MB it should have read 512M of memory sorry. Anyway with 8 4Gig modules the point is mute. Great job. On your way to reviving a great machine!

Hello everyone,
I have uploaded version 11 of the pikify3.1 bundle to the original post #1390
It should detect a v9/v10 modified 'Install OS X El Capitan.app' reset it, and then continue on to build an installer that will fit onto an 8GB USB memory stick.
Sorry it was bad design on my part. But I have fixed it now (hopefully
)

Verified under 10.11.4 and 10.7. Thanks rthpjm !!
Slightly off topic, but someone may be able to advise I hope. I just bought a Radeon 7950 Mac Edition and I don't get any boot screens. I have tried the jumper switch in both positions and double checked everything is seated as well as trying in slot 2. Card is reported as AMD Radeon HD 7xxx 3072MB but when checking PCI in System Profiler it says "error gathering device info". When cold booting I also get the main start-up chime - followed by 3 shorter and quieter slightly cut-off chimes. It does then boot into El Cap (or Yosemite).
Does this sound really bad or could it be fixed? I could return the card but as they are relatively rare I wanted to check all options first. Any advice would be gratefully received. Thanks.

If it is being Displayed as 7xxx the card is using the "PC" type bios. Now it could have been installed with 2 "PC"type BIOSs or the switch is broken. BTW which display connector are you using?
Hi, I have my 30" Cinema Display connected with the DVI connector. Just spoken to the guy I bought it from and he says he never had boot screens from new - good of him to forget to mention that! I have tried the switch in both positions and it doesn't seem to make a difference. The 3 "soft short chimes" after the main chime are a concern too. These only sound on cold start - not reboot so assume somthing to do with POST? Apple seem to suggest they are efi related so I guess it is likely the is the same issue as no boot screen.

Found this capture is what yours "should" look like. "I" would get some form of refund for a "MAC" card that does not work as specified on a MAC and "flash" one of the ROMs. YMMV There are Posts on MacRumors about this card and what to do.

Thanks for info - screen shot attached of mine. Do you think the 3 chimes are directly related to this - and is this anything to be concerned about before I possibly flash the card? I bought this as I thought it would save time and effort in flashing, rather than a PC card.

My Mac Pro 2,1 running 10.11.5 has started buffering video. It has 13gb RAM and just started to do this. Any ideas?
Unless the files are on your local hard drive, I'd say this has to do with your internet connection, not Mac.
Hello Ant,
Does the card have any Apple branding on it, especially the silk screen on the circuit board?
Have you read this https://support.apple.com/en-gb/HT202768 ? Your symptoms suggest a corrupt EFI ROM, although from that article, 3 chimes is associated with bad RAM, but it could be the longer sequence being cut short. Have you still got you other card, have you swapped that back in, did the chimes go away?
If the 7950 is not Apple branded, then it sounds like you purchased a PC Card where the seller has attempted to flash with the Apple EFI and got it wrong. It's not an uncommon practice because selling something as Apple compatible often commands a premium price.
The good news is that it's probably fixable.
Is it a Sapphire Mac Edition? https://eshop.macsales.com/item/Sapphire/100352MAC2/
The other possibility is that the previous owner used the card in a PC and flashed PC BIOS firmware onto it with differing overclocker profiles. They may have tried to put the Mac Edition firmware back onto it and messed up...
It looks like there is a Sapphire Mac edition ROM here http://forum.netkas.org/index.php/topic,5619.msg19338.html#msg19338

Hi, yes it is the Sapphire Mac Edition the same as in the link. I had some bad RAM once and I thought it made a beep rather than a 'chime' this is like a muted startup chime that is slightly cut-off. I tried pulling usb devices and the 3 chimes appear to be happening when my WD 2TB back-up drive is installed and not doing it when the usb is pulled. Weird, as this was all OK until adding the 7950 but not sure how they can be connected. Replacing the 5770 card fixes the issue even with the HD connected - which is odd.
Yes, I had seen the Apple article, but none of the descriptions quite fit - the efi issue seems to be a repeating sequence of different lengths according to Apple. I think if I moved the switch on the card to the left I got 4 chimes though. I also zapped the PRAM and at the moment the extra chimes are no more.
Been looking at the ROM stuff and flashing the card - it all appears to need Windows installing which I guess is another layer of hurt to deal with. Looks like I have some reading to do. It seems some of these cards may have been faulty from the factory having 2 PC ROMs or a faulty switch.
I contacted the seller and he said he never had boot screens but he was using it on a Mac - he said he bought it from new. He also offered a refund without being pushed so I think the guy is probably not making this up - just wish he had mentioned the boot screens BEFORE.

It did cross my mind - the external HD has it's own power supply though and only other usb items at boot were the KB and usb supply to monitor.
Even though I thought this was fixed it is now happening again - pulling the USB to the self powered HD and it boots with normal chime. I have not heard of anyone having similar issues so assume this card should work OK without drawing too much power.
I need to decide if this is more trouble than it's worth and perhaps return the card - or try and fix it. It cost £170 but I could probably get a PC card for less and I still have the hassle of trying to flash it.

Could the Mac Pro be (unsuccessfully)trying to boot off of it? I have seen one of mine try to boot off of my phone and different USB thumb drives. Just a thought.....nuke the bootblock?
Thanks for your help - Mmm, interesting. I have 4 HDD (inc 2 SSDs) in the Mac as well as the external Time Machine drive - How would I stop it trying to boot from it? I looked at installing Bootcamp and the place it offered to download it to was the external drive, not any of the internal drives I have. I didn't install as it looks like I would have to pay for a copy of Windows which is starting to get more and more expensive way of fixing a card that shouldn't need fixing.
Currently pulled the card and back to 5770 and all is normal.
Forgot to add - these chimes only happen on cold boot - not restart.

You got me worried now
Do you see them here?
This MSI i have now seems to be a lot more tortured in its life span than Gigabyte i had previously.
I would recommend returning the card if you're not satisfied with it, but if you have will and time, you could run Bootcamp on a small partition and extract cards ROM, just to see if somethings wrong and if it can be fixed...

Hi, I was just reading some of your other posts on Mac GPUs! I have now pulled the card and replaced the HD 5770 and plan to return it. The weird "3 echoes" of the start-up chime (when external HD is plugged in), no boot screens and now artefacts appearing make me think this is not what it seems, or has also had a rough life. Seller has accepted return so it's going back. The artefacts were as on the pic and around the shadows of windows and around icons in the dock - maybe a sign of something failing? I tried it with the switch in both positions and had the same result. Seems a bit of a lottery with these things.
EDIT: Just looked back at my pic I posted and the artefacts are not there! Presumably a screen grab doesn't record them. They were there with the 7950 in place but I guess they were being created 'live' rather than being captured.

In my experience if a screen grab(which is basically a video memory dump) and the displayed video(which goes through additional circuitry on it's way to the display) IS an indication of "other" problems. Good move on returning it.
@Ant3000 It sounds exactly like the thing i had with my HD6850 and that was all due to PC bios.

Card most probably doesn't have Mac EFI or Bios switch doesn't work and it is stuck in only one position.
I say return it, buy regular reference version (MSI, Gigabyte, Sapphire with DVI, HDMI and 2xmDP) and we will flash it in seconds. You'll just have to provide Bootcamp or some PC to do the flashing in.
P.S. I assume that we can successfully flash that card you already have, but it will be much cheaper to return it.

Hi Everyone,
I have read the above posts on issues with the (perhaps isolated case of) problems with the HD 7950.
One small comment on that story from my side: - assuming you have put that card in a mac pro 1.1 - sadly you can never harness the power of that card in a mac pro 1.1 - PCIe version of the motherboard is a bottleneck for the card in addition to others... I very strongly considered buying it for my mac pro 1.1 but settled on something that was less overkill (HD6870 (used 30€ - see below) in comparison with the HD7950 (used 100€) in the mac pro 1.1 and allowed me to invest in more RAM.
SO, I currently have an unflashed PC version of the HD6870 (HIS version = ADM reference design, 1GB DDR5) installed in my mac pro 1.1.
it shows up in the system profiler (see attached) under 10.7.5 (and in a similar way in 10.11.0) as ATI Radeon HD 6xxx.
It seems to work flawlessly - smooth gaming experiences included.
I have windows installed and am brave enough to take up the challenge to flash it (still need to read-up on how-to).
BUT : Since i'm on a mac pro 1.1 with 32 bit efi on the motherboard, I doubt I can add any additional functionality by flashing the GPU...
Without having done the in-depth read-up on netkas etc... could someone tell me in a nutshell what I could gain from flashing my HD6870 installed in my mac pro 1.1 ?
Some of my questions include:
- will flashing my HD6870 put a 32 bit bootloader on my card so it will show the osx boot screens?
- will my HD6870 even 'run' that 32 bit code ? - I assume the card is 64bit?
- If flashing the card would not produce the benefit of showing boot screens - will the flashing at least give me better support or performance in osx (e.g. proper recognition of the card instead of ATI Radeon HD 6xxx )
Many thanks in advance for your constructive comments!
