HD 4770 softmod to FirePro V8700, success!

[Clint]

http://forums.guru3d.com/showthread.php?t=275174&page=8


Before mod: CPU@2500, GPU@800, GDDR5@850



After mod to FirePro V8700 CPU@2500, GPU@800, GDDR5@850



After mod to FirePro V8700 and OC CPU@3500, GPU@950, GDDR5@1150



Resolution 1280x1024

not bad for a $99 card...

Hi Clint,

Can you post the exact procedure to arrive to this amazing result ;-) ?

[987987]

fuenciona para la 4850 ???

[987987]

Could anyone make a video? To see the difference in skechup?

[hedisurfer]

Clint don't let us alone pleeaaaaaase

[NormanBates]

everything is explained in the thread he pointed to

thanks to recent developments, most ATI cards, if not all, are moddable (yes, that includes 4850)

[hedisurfer]

Hi,

Can you tell us where exactly (which page, which post) ?

[NormanBates]

from the bottom of page 6 and on, I'd guess

plus here are the instructions for the old mods (which won't work on any HD4xxx card)
http://forums.guru3d.com/showthread....highlight=lazy

the new drivers come already modded, sometimes; in other ocassions, there's a script, and the instructions above should work

[Clint]

Sorry for late reply.

Yes, as NormanBates says, the patchscript used is in that thread. You need to modify that script a bit:

1.
I used Dst1_12 line which is eqvivalent to the HD 4870 card. The line looks like this:

Dst1_12 = 0F B7 85 FE FE FF FF 66 25 00 00 66 0D 56 94 66 89 85 FE FE FF FF EB 04

Edit it to reflect the HD 4770 hardware-ID (change "56" to "B3", which will translate to a hardware-ID of 94B3 (reads from right to left)):

Dst1_12 = 0F B7 85 FE FE FF FF 66 25 00 00 66 0D B3 94 66 89 85 FE FE FF FF EB 04

2.
As allways when softmodding you also need to change hardware-ID in drivers .inf to reflect your card:

In CX_79796.inf find this line:

"ATI FirePro V8700 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_9440

Edit it to reflect HD 4770 hardware-ID:

"ATI FirePro V8700 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_94B3

3.
Look for tutorial on how to patch this driver with Rivatuner and then use Gellmars (edited) script to do so.

[hedisurfer]

Thankx so much

[987987]

-You can make this change in bios? to save all these problems
-It is compatible and stable at 100% with all the programs?

[NormanBates]

* can't be done in bios, only in drivers
* at least with previous mods, is just as compatible and stable as a real fireGL / firepro

[matt2k]

right, a few questions.

I have 2x 4770 running in crossfire atm, so to softmod them to V8700 i have to install the firepro drivers and then mod the script like clint said above?

would they still be able to run in crossfire?

[987987]

Patch Scrip for Firepro 8.543 ???

[partyboy]

I modded my cards

saphire 3870 modded
firepro 9170 on xp32 (8.44)FULLY WORKING
and v7700 xp64 (8.4X.1)FULLY WORKING

1 or 2 hours later system immidiately restarting.always doing this XP32 AND XP64


and i just bought

xfx 4870 1gb moded v8700 (only work %90 fine in x32 DRIVER 8.603 MODDED DRIVER DOWNLOADED INTERNET)
this restarting too (LIKE 3870)

BOTH CARD RESTARTING IN 2 HOUR
(LEAVE COMPUTER IDLE AND INTERNET DOWNLOAD ----OR---- FULL 3D BENCH ALWAYS RESTARTING IN 2 HOUR)
I LOWER GPU MHZ AND RAM MHZ AND DONE IT AGAIN

is there any fully stable card...for long usage
3870 fully works
4870 neraly fully some scpec test not working bur solidworks work fine.


SPEASE HELP ME I REALLY NEED A STABLE CARD.

[Cute09]

I'm very new in softmodding. I have tried to mod my 4770 by modifying patchscript according to your guide but not success yet. What driver of FirePro you use Clint ?

Oyeah.. I'm using RivaTuner v2.24, Gelmar's PatchScipt and modded FirePro 8.603 driver from Wesley8. Could you bring me your complete modded PatchScript SoftFireGL w2k, RivaTuner.cfg, CX_79796 and of course, link of modded FirePro driver you used, please ?

Thank you very much Clint..

you shouldn't mod an already modded driver: get the official one from the amd site

partyboy: I'm not sure what the problem in your system is, mine is working 24/7 with modded 3870, and another one 5 hours a day with a modded 4670, both with no problems at all

[Maryus3D]

Could someone test a modded card with this scene. I beg you! Is an island from a tutorial. The scene is very heavy. I'v got around 5 fps on my 9800GTX . So i'm very curious on an modded HD4770\HD4850\HD4870 how many fps do you get .

http://rapidshare.com/files/24494567...scene.rar.html


Sorry for my bad english is not nativ

[NormanBates]

I'll test it tonight, on modded 3870-512MB and 4670-1GB

[Maryus3D]

Thanks a lot NormanBates . I appreciate a lot .

[NormanBates]

I downloaded the file, extracted the .ma into a local drive, opened it, closed render and hypershade windows, and alt-dragged to rotate camera, looking at the stated fps (which varied quite a bit, depending on how many trees there were on camera)

3870 512MB firepro 8.453 - Q6600@3.0GHz - 2GB RAM - 5 to 14 fps
4670 1.0GB firepro 8.603 - Q6600@3.0GHz - 2GB RAM - 7 to 18 fps

I first tried to press play instead of rotating the camera by hand, but it freezes (0.1fps), with the CPU computing the position of the leafs (and swapping from the HD - I hate that)

the scene seems quite workable VGA-wise, but it's an excruciating pain for the CPU... which is not helped by the fact that maya is only using one core

by the way: you didn't include the .jpg and .tga files in the zip, so it didn't display those textures

(and yes: I didn't even bother to install the new drivers on the 3870, in fact I'm not using maya at all lately, it's fortran that's trying to pay the bills)

[Maryus3D]

NormanBates 10x a lot . I'v got the same results with the textures on the scene. ( 5-14 fps win7 build 7201 x64) . So I will keep my 9800GTX for a while.
Just last question. Do you think a Quadro FX 580 will get better fps or is just the CPU fault. I do a lot of modeling in maya. What do you think is better for me a modded HD4xxx under xp maybe near future win7 or Quadro FX 580 wich is a real Quadro unde xp\win7 (vista sucks)\linux even OSX . Is there a huge differences between Quadro FX 580 or modded HD4xxx in normal scene like a complex caracter or something like that without paint effects & textures just a lot of smooth mesh, nurbs etc?I just saw this video http://www.youtube.com/watch?v=Y99mD_A1uug . There is a huge diferences between HD4850 & V3750. Do you think is the same for maya? I think the Quadro FX 580 is better then V3750 because it has more memory . So who has the bigest advantages? The modded HD4xxx or the Quadro?
Anyone?

i get 15-22 fps in win7, but 22 in specviewperf. I guess this benchmark doesn't reflect true viewport performance.

[khogan112]

I have a Quadro FX 570, FX1800, FX 380, FX580 , FirePro V3750 and FireV5700 for testing.

I had run SPECapc Maya 6.5 benchmark on Maya 2010. Except that, ı have no idea how to run Maya.

Therefore, where do I see the fps ?

[Maryus3D]

Go to Display\heads up display\frame rate. It will show on lower right corner .
