Yes, the card will work. It is compatible with efi 32 and efi 64. But it will work at 2.5GT/s.
I ran the script myself, so here is the rom for the above mentioned card.

Very interesting topic.
So from where do you buy trustworthy 215-0798000 chips?

Hello, i'm experiencing stuttery and laggy mission control/full screen swipe behavior and its becoming worse since updating to Sierra.
it gets worse the more safari tabs/windows/fullscreen Apps i have open simultaneously.

connected monitors:

1 x 1920 x 1080 -> HD 6850 pci slot 1
1 x 1920 x 1080 -> GT 120   pci slot 4
1 x 1280 x 1024 -> GT 120        ''

About this mac shows nvidia gt 120, is this shitty card doing all the calculations?

is this because I'm using nvidia and ati at the same time, or is my hd5860 2Gb too weak for my needs ?

Do i need a metal support GPU for smooth mission control ?

will a single card solution sort this issues out ?
im kinda looking forward to a r9 280x but I'm a bit scared of the power consumption/heat generation,
do these cards require only little power in desktop usage? for example logic pro on multiple screens, because heat is quite some problem already in my studio in the summer
is a r9 280x loud on desktop or only if gaming ?

you guys are killing me

make giant mountains out of tiny mole hills

instead of re-inventing wheel from the spoke stage, do the easy stuff, even if it costs you $20 extra

what you mean? about costs in $20 extra

It looks OK, the only person that can  prove it's ok is you.

Be sure to have a backup of the original rom, and flash the card with the mac-rom.

Restart your mac, and see if it starts with bootscreen and comes to the desktop screen.

If it doesn't work, it's back to the drawing board.

Hello. I just purchase a Sapphire HD7870 for 25.00, the only downside being that one of the fans does not work.

I am curious if anyone could confirm if this card will work, following the method in the initial post and if so, will it be EFI32 compatible or just EFI64? I am hoping to get this to provide a boot screen for a 2006 Mac Pro.

The exact card:

Thanks in advance for any info you may be able to provide.

Ok, so if I am understanding you correctly then mine is seemingly correct? In any case, thank you. I appreciate you taking the time to respond.

Just out of interest, would it be possible to program the smc chips with one of these:
No idea I know some people tried to get the smc but there was never an official project...

I dont recall the fans running fast, but I was doing the swap in a large warehouse. I have done a couple of 09 to 5,1 flash, and the firmware did not change when I installed a stock 2x 2.26 daughterboard. So the flash changes the motherboard version, and not the daughterboard(cpu tray).

I've done the swap, and it worked fine. Maybe you should take your own advice.
You updated a 2010 backplane with a 2009 processor board and the fan are not going full speed all the time
Post a screenshot of your system hardware profile where we can see that you have a system with 1.39F11 SMC version (2010 Mac Pro BackPlane) and a 1.39F5 SMC version (2009 Mac Pro CPU Board) plus with a little video of that Mac Pro operating without the fans going full blast... it's been reported dozens of times in the past that it couldn't work... I even experienced it myself as did others on the forum as well... I think you just didn't read the post (What I quoted you answering to) properly or didn't understand the question he was asking...
Can you post a screenshot of that because it is well known you can't get an SMC from a 2009 backplane and a 2010 CPU board to update to the same version and the smc controller will then cause the fan to go full blast after a couple minutes of operation... thanks

cornflakes1023, i think you are right. For myself i would need an example of a fixed rom which works, and a example of a not working (one MCUC) to compare to each other.

As i don't have a videocard to test it on right now, i need the assurance that the 2 MCUC version actually works.

This way i can physically see the the difference between the 2 roms.
Rominator has written a fantastic guide, but i need examples to see what's going on.

I need to correct myself, the second MCUC, should be placed after the EFI part.
It's all explained in Rominators guide.
