I have this chip programer already. I used it to flash my titon ridge thunderbolt card.
Got a tip for us?

Yes, it can be bit of a nightmare to get there for this cards!
I have some brandnew RX 6800 founders, which i wanted to flash with the programmer. I allready had the backplate off. As i realized the cooling unit did not even come off easily with all the screws removed, i gave up and looked out for some friend with a PC. I didn't want to damage or even destroy something at this expensive card. Later i read somewhere about the cooler beeing glued to the GPU-die with some sort of carbon/epoxy.
It sure is not an easy and riskfree task to get this thing off!
Hence my recommendation for a cheap PC build. There are also other alternatives, but non of them will be cheaper:
Egpu thunderbolt adaptor
for the above you will need a Mac or PC with thunderbolt
M.2 M PCI-E Laptop External Independent EXP GDC Graphics Card Dock
Metal score for RX6950XT spoofed in Ventura is 236518:

Radeon RX 6950 XT
I disguised the 6950xt as a 6900xt.And run in masos 11.6 Thanks gs7yme! This was the missing piece I needed to spoof my 6950xt to a 6900xt. I also had to add a couple of lines to get to the correct PCI path, which I discovered wasn't quite correct using Hackintool on the Mac. IO Reg Path...
Sure there is: Having a friend with a PC, owing you some little favor! 😝
I am not sure, but has anybody actually tested booting the unflashed card alongside an RX580 to Bootcamp where the 6000 version card is NOT connected to a display?
Any NAVI 2x card unpatched installed will make the Mac Pro to not complete POST. You can't boot anything, it does not even chime.
If you know someone with a 7,1 Mac Pro they can also flash it for you in Windows.
That’s how it did my RX6600XT using my 7,1 and egpu enclosure along with windows 11.
Any luck? same thing for me Mac OS Monterey 12.6.5 60hz Windows 120hz with Aorus 48 inch oled. Using display port tried hdmi 2.1 also but no luck with rx6800xt
Just installed a Sapphire Pulse RX 6600 (no XT) on my 4,1 > 5,1 ... everything is working great.
I followed your instructions for "fixrx6x00rom" and everything worked at first try.
I'm using the flashed card on my main Mac Pro with latest Monterey (actually 12.6.6): I tryed it on my second Mac Pro with Ventura but I had problems during booting process ... maybe I forgot something to do on Ventura ?
Here some bench scores:
- RX590 (old card) > 39.447 (Geekbench 6 - Metal) > 36.611 (Geekbench 6 - OpenCL)
- RX6600 (new card) > 84.492 (Geekbench 6 - Metal) > 47.840 (Geekbench 6 - Open CL) > 21.752 (LuxMark)

Apple has blocked 4k 120hz for AMD 6000 Series cards, even though they support hdmi 2.1.
Any hackintoshers or e-GPU owners with 6800 XT getting 4k 120hz RGB 10 bit? The same AS Macs with hdmi 2.1/USB-c ports can easily do 4k 120hz RGB 10bit.
A real shame good hardware gone to waste.

Try Linux, just make a bootable LiveUSB is good enough, no need to install anything.
So my pc is old. it has a athlon 64 in it with 2gm ram. says i can't put windows 10 on due to cup. been trying everything to get amdvbflash to load it just won't. I can do everything except get the flashing program running. here is a pic of what gpu-z shows.

But what is the monitor reporting? There will be some button when pressed , will show details of the receiving signal. usually a small info window. That window should show resolution/refresh rates/color depth...etc.
What is the info shown by the monitor?
Apple never allowed 4k/120hz RGB 444 10 bit as of now. you may get 4k 120hz , but not full RGB 10 bit.
For e.g I have a LG CX , when I press the green button on my remote. it shows all the details. With a RX 6800 XT on Ventura 13.4. Best I could get was 4k 60hz RGB 10 bit or 4k 120hz YCBCR 420 10 bit. We do not want YCBCR. We want full RGB 10 bit.
1. Did you install the flashing driver?
2. Try this: https://wikidll.com/microsoft/gdi32-dll
3. Reinstall Windows (I' not sure a Windows computer that old will work with his GPU anyway)

if your pc is that old, you can try the dos version of
AMDVBFlash.
