Well I was kicking around looking for a project to do so I set about converting my Zotak 8800 GT 1024 MB PCIe card and NVIDIA 8800 GT 512 MB card to Quadro FX 3700's.

This is a bit trickier than normal as just changing the softstraps and device id resulted in the card being displayed as a device id of 0619 instead of the 061A that I was looking for (Quadro FX 3700). Well after much messing around, I managed to get both of them up and running showing up correctly in system profiler with the correct device id & memory.

Here is a link to the roms:

I have only done the 2 cards listed above so far, and before everyone starts PMing me I am away till the end of the week. Also, although these should show up correctly in Hackintosh & Windows I still don't know if there is significant improvement in windows Maya/Spec View and so forth as I don't have it to test.

would it work with every 8800gt card you think?

Hi Stellair,

There is a fair chance it will if you have a 512 card. Which card brand do you have? The std speeds for my card are 680/1600/1900 from memory which is faster than some, but can always easily be adjusted down with Nibitor. If you can save the rom from your card, send it to me and I will see if it is compatible. In the download, I included the original 512 rom from my card, if you compare this with your own cards saved rom in hexeditor and they are the same, you are good to go

Good Luck.

Hi aqua-mac,
I have an MSI 8800GT OC 512MB card and have dl's the rom. Comparing it with your original 512 Nvidia
rom, I got the following diffs. I don't know if it is significant. I'd appreciate any feedback and help. Thanks.

Compare error at OFFSET 36
file1 = 14
file2 = A4
Compare error at OFFSET 38
file1 = 31
file2 = 30
Compare error at OFFSET 39
file1 = 30
file2 = 31
Compare error at OFFSET 3C
file1 = 33
file2 = 31
Compare error at OFFSET 3F
file1 = 37
file2 = 38
Compare error at OFFSET 54
file1 = DE
file2 = 62
Compare error at OFFSET 55
file1 = 10
file2 = 14
Compare error at OFFSET 56
file1 = 3C
file2 = 70
Compare error at OFFSET 57
file1 = 5
file2 = 11
Compare error at OFFSET 6D
file1 = AF
file2 = E1
10 mismatches - ending compare

why would you flash your 8800GT to FX3700?
i care about perfomance, special in pro apps (8800Gt is no good there..)

i know xbench is a {censored} but i also know the standard results for 8800GT
so, can you please post gfx benchmarks after u modded the card to FX3700?

i did some tests..
in glviewer the results are almost the same (-200) so it's not such important in order to flash a card
but in openmark u have 44255 and i got 34877
and openmark is a good gl benchmark for me cause it;s duplicating everything in the stage
are u sure u did all the openmark benchmark? (about 10 minutes)

anyway post an xbench result also please
and if you have cinebench10 do the opengl test (8800GT normal gives around 6500)

Aquamac, can I ask what method you used to flash your card? Did you use a bootable USB drive, floppy, etc?

I used a USB floppy to flash my cards. Yes I did all the tests in openmark, there would be no point in publishing results with only half the tests. What res are your tests - that makes a difference.

Xbench is literally not worth using as it has virtually no relevant tests for modern graphic cards.

9800 GTX has no equivalent Quadro card.

Maya works a treat with these cards, but I did not test with the 8800 GT roms beforehand unfortunately.

But the 9800GTX has the same chip as 8800GT: G92. :(

Thanks for the information !!! Actually you are my last chance, ... but inbox of all the participants of this
thread are full, so maybe someone read this and will get help here.

In aquamac's upload is another folder for the Nvidia 8800 GT with two .rom files. What to do with them ???

A short instruction to the process would be helpful.

Is it possible to get the old type of card back after flashing the graphic card ?!

Answer/Reply ... would be very very appreciated, so the 8800 GT isn't that good at all when it comes to 3D performance. Was very disappointed after buying it.

Best wishes, Micheal

thx mate .. :D

i think i works on any card since my card is inno 3d 8800 gt 512 mb which is "not the best money can buy"

and the 2 folder in the download is for the 1000 mb and 512 mb video card ithink

Get an old PCI video card best if it is a non-nvidia variety and the latest nvflash program which you put on a bootable floppy along with the .rom you wish to flash too the 8800GT. Now once you boot from the floppy you use the nvflash to backup your existing ROM on the card then flash the new shutdown then start the machine again and hopefully it worked. You would have wanted to set your BIOS to initialize the VGA card first before the boot from floppy to flash then have changed it back to PCI-e/PEG in some BIOS to check the result.

Is it possible to get the old type of card back after flashing the graphic card ?!


Yes you just use the original .rom file you saved to flash it back again.

I have an original quadro fx 3700 card. Exists any drivers for this graphic card in Leopard?

Please reply. I'm very interested to install leopard for work with it.

Thank you.

Hey aqua-mac,

is it also possible to run the nVidia Quadro Drivers on Windows Vista with this BIOS-mod?

The question is whether I buy an old 8800GT and flash it to a Quadro FX3700 or to wait for GTX260/285 support and (if possible) flash it to Quadro CX/FX5800.

Quadro FX5800 for 300 Euros would be damn sexy. ;)

Anyway, thanks for your effort aqua-mac.

btw: I love your stock look Hac Pro. Will there be a new Nehalem Hackintosh?

Thanks for your comments e1ement, funny you should say that, it's bit of a longer term plan, but I am sure that there will be a core i7 hack along the way, in fact so far I have the board - a Asus P6T6 Workstation board. Still saving for a processor!

There will be a problem on the face of it, changing the current GTX series cards to Quadro, as "soft-strapping" can only be applied to the last digit of a device id.

As you will see from the details below the two latest Quadro's also have the second digit changed. This is probably set by resistors on the board itself. It would be great to have an example of an actual Quadro FX 5800 to study the resistor layout (or high def pics of both sides of the board), but I cannot see that happening due to the vast expense!!

Device id's for current crop of top GeForce/Quadro Cards;

0x05E1, GeForce GTX 280

0x05E2, GeForce GTX 260

0x05E3, GeForce GTX 285

0x05FD, Quadro FX 5800

0x05FE, Quadro FX 4800

0x05F9, Quadro CX"

That's not what I hoped to hear but the Quadro FX3700 won't be a bad card for my needs. The FX5000 Series would just be some kind of prestige. :star_smile:

Have you already looked at the ATI Workstation series? As far as I know is there a possiblity to modify the drivers so it shows a HD4870 as FirePro V8700. I also found out that changing the DeviceIDs will cause the video card to report as FirePro V8700 but so far it wasn't possible to install the drivers within windows.
Without DisplayPorts the HD4870 1GB seems identical to V8700. Palit/XpertVision's Radeon HD 4870 Sonic has two DisplayPorts and one DVI-connector. Maybe this on will be a good V8700. With Mac OS X 10.5.7's drivers it will probably be possible to run them without any bigger modifications to the OS itself.

It would be great to have an example of an actual Quadro FX 5800 to study the resistor layout (or high def pics of both sides of the board), but I cannot see that happening due to the vast expense!!


Ha, for every GTX-Series video card I can find pictures of the board layout but no one disassembled a Quadro card. :star_smile:

//EDIT: http://www.macrumors...boost-and-more/

... a Mac Pro bump to 3.2GHz with Quadro FX 5800


That means GTX-Series will work and maybe it will be doable to flash a GTX285 to Quadro FX 5800.
