What does your k1100 card look like when it is installed on that heatsink? Are you sure it is straight and not at an angle? I had to use a shim to raise up the contact surface on the heatsink so that the card was even.
Hi, please just read page one of this forum. It contains, facts, links, hints and howtos to everything needed and to all your questions.
Hi Ausdauersportler.
Hi Nick, first of all thanks so much for breathing new life into these machines. They are awesome and perfectly suitable to the average computer user. I'm loving running Catalina on a 27 3.4 i7 2011. I have a few questions for you, would appreciate your input.It seems St. Nick is running a few days late this year, 🎅
or maybe a few weeks early, depending on where you live…
Quadro roms attached, for the following cards:
K1000M, K1100M, K2000M, & K2100M
They all have CoreEG2 integrated so no boot-rom mod required.
The clocks should also be unlocked in windows (not P5 limited)
and they have a moderate over-clock which should be stable.
Thanks to @highvoltage12v for running the K2X stability tests,
so if your iMac crashes, for any reason, it’s totally his fault !
I have native brightness control & Target Display Mode working
so far only on the two newer cards (K1100M & K2100M)
At the moment this will require using the OpenCore boot-loader
to do some ACPI injection, and maybe load some additional Kexts.
I’m working on a plug-n-play version that runs from a USB stick,
but there are still some things to fix so that may be a few weeks out.
Not forgetting the red team…
I worked out what was limiting the boost clocks in MacOS,
these Beta3 roms should now be completely un-limited.
I’ve also included an over-clocked version - but be careful,
it will produce a lot more heat so make sure you crank the fans up!
I’m still working on a fix for that code 43 driver issue in Windows,
and hoping we can use OpenCore to work-around the problem,
as it can also be used to enable “iMacPro” HEVC encoding for FCPX etc.
The boot-rom mod is still required for AMD, probably always will be,
It’s included here but there are no changes so no need to re-apply it.
UPDATE for K1100M !
Well this is embarrassing... turns out I'm an idiot!
I accidentally uploaded the wrong file for the K1100M
If you downloaded the previous version do not flash it.
No other cards effected, I have updated the download.

Pretty sure you have got to use APFS.
Here you go.
They do, but not for the right reason, they are installed with all the other Graphics kexts, which breaks our iMacs from proper functionality with a Metal supported card. He could fix this by creating a separate "iMac graphics patch" checkbox for the patcher, but never answered my PM's. So we all have to do it my way.
HiGot it working
I am using a dell Quadro K3000M 2Gb. I have anouther 2011 27" iMac, I might try a K3100M in it. Pretty sure it needs to be a Dell or Alienware card, I have never herd of anyone getting an HP card working.
I tried installing El Capitan (via pulling the HD and installing with a different Mac) started the computer, took forever the first time, but the screen came on and worked perfectly. I may try sierra again, i think the only problem is that kext file. It doesn't matter at this point though El Capitan is fine.
Thermals on this card are good, ran the Valley benchmark at the highest preset and topped out at 76C, idle is around 50C. This card is not a large upgrade from the stock (though it is decent upgrade from the 1Gb 6970M mine had), it does make a great replacement for a dead card, at a reasonable price. I got mine for a steal ar $40 but they are easily found on ebay at around $75.
I can provide screen shots and benchmark results upon request.
Note: Anyone looking to use a K3000M, I can only confirm that one from a Dell will work, I have not tried the HP one.
What that means is you don't have a good connection. Unfortunately sometimes it take 5-10 tires to get it right. And sometimes it will appear it's working, but Everytime you press "detect" different values will show up. It's kind of an art you have to get down. I always look it up close and at eye level.
