in general this is a valuable experience.
it can be useful to all who wish, extend the life of your imac.  .
Rominator,  special thank for your work, and a significant contribution to everything.  .  

At the moment, work is underway to upgrade the 6970M video card with video memory expansion to 4096.
you will be the first to know about the results.  whether it's good or bad.  .

There is still a space plan, at 8970M which speaks of itself "- I can work in imac", in theory everything indicates this.  for example from

AMD7000Controller.kext - device id 68c1.

so intresting that, FrameBuffer is - pitcairn

How do you think Rominator, EFI part from Desktop Video Card "Pitcairn" theoretical can be approached?  and whether it will be necessary to edit the device id already in the Decmpressed EFI part.

I know this is an old thread but since my question applies to this precise topic, I thought it would be acceptable to revive it.
From what I have read on this and other sites, it appears that the only ill effect of swapping processor trays between Mac Pro 4,1 and 5,1 computers (provided the 4,1's firmware has been updated to 5,1 status) is that the system's various fans will run at full speed. If this is indeed the only ill effect, will a utility such as Mac's Fan Control solve the problem?

No, because MacsFanControl actually control the fans via SMC. And the fans will run at full speed because SMC now is not working. Therefore, most likely no existing software can control the fan.

Disable TRIM can fix the boot time issue (and may be a few oter annoying bugs e.g. Finder micro freeze)

Has anyone tried installing apfs on a mac pro 4.1 with the latest public beta?
I have been running 10.13 on my 5,1 since beta. The required EFI flash for APFS boot happened during one of the late betas and worked fine with my flashed GV-R797OC-3GD GPU. Since I run an SSD on a FASTA card as boot drive, it normally will update that card on install.
I found that boot times went from 13s to 3 min! I also ran into sleep problem with 10.13.2 unrelated to APFS.

I wiped the disk, formatted with HFS+, installed Sierra and then upgraded to 10.13.1 for now. I have a test partition with the betas to see, when it is safe to upgrade further.

Overall performance is not very different except for that boot issue, file copy (clone,) and some other things like changing owner ship over a hierarchy, which is really fast.

I have a 2006 MacPro Tower upgraded from 1,1 to 2,1 and Yosemite 10.10 installed via the ( pre-patched Piker-Alpha bootable Yosemite installer ) with a unflashed Gigabyte R9 280X REV2 card outputting 4096x2160 on my 4k projector.

I was able to install Windows 7 Ultimate 64bit on my early 2011 macbookpro 8,2 bootcamp partition and then load the bootcamp drivers via my 10.6.6 install disc without a problem since this machine is 64bit. I then use Winclone to copy that install onto the MacPro tower's NTFS partition. It booted up, it worked!!!

I needed to go this route because of the following: You can load the newest version of Windows 7 64bit onto a MacPro NTFS partition, but Bootcamp will not allow you to load its files onto that partition as it must see the 32bit Efi. This can be a huge pain, as you may want to see your HFS partitions, drives, and have the drivers for all the Mac hardware/peripherals. Well.. I can now see my mac drives and use the bootcamp control panel in Windows 7 64bit to reboot into Mac OS 10.10 Yosemite!!
No BSOD! No Bootcamp files to disable. No glitches.

I'm really happy about this as Windows 7 Ultimate 32bit is limited to 4gb ram usage but was listing only 1.99gb usable for me.

I'm glad that I did not have to go through all of those steps listed in this link:

http://www.fluxbox.co.uk/2009/08/26/windows-7-64-bit-onto-your-mac-select-cd-rom-boot-type/#search=windows+

and here:

http://www.richardfrankhuff.com/archives/142-Apple-MacPro1,1-Running-64bit-Windows-7-Under-Boot-Camp..html

That sounds great! But how did you install the Bootcamp drivers from the Snow Leopard DVD? Is it possible to just put in the DVD and install them under Windows?

Thank you very much in advance!

Best regards,

David
