GeForce SoftMod - Dual Config


Recommended Posts

Looking at some new machines,; we were considering the Quadro line as we've always used, though I'm intrigued by the thought (in reading here), about soft-modding GeForce cards to run as Quadros. If I were to buy 2 GeForce cards, (planning on soft-modding them to run as the fastest compatible Quadros), what would be the fastest GeForce cards that this would be possible?

 

8800GT --> Quadro 4600?

 

Would this be stable?

 

To be used primarily with Max in a Dell box / dual Xeons, but Revit will also be used on the machines (as I understand that FireGL would be best for).

 

Thanks for any thoughts,

J

You can't softmod an 8800GT or a new 8800GTS (the 256/512MB version) with the current software. You can mod an 8800GTS 320/640 and I think you can do an 8800GTX, but I'm not sure.

 

There was a thread that started as a Geforce vs. Quadro discussion and devolved into a softmod discussion; I don't have time to search right now but look for one with geforce vs. quadro 1700 in the subject.

Thanks, I hear you. It would be an after market add on for sure. Can't even get that card in the system I would order. Thus saving the original is a must.

 

So, soft modding 2 cards in the same box is no issue then? If I were to buy 2 8800GTS cards (320/640) / soft modded?

 

Is this solid in 64-bit as well?

 

Thanks,

J

It looks fine and it's hard to argue with the price.

 

I'm throwing in another caveat here just because I don't want people getting way too excited and then maybe disappointed:

 

I've done this in XP 32-bit on particular Geforce 8-series with the G8x GPUs, not the G9x. Not 64-bit Windows, not Vista, and I haven't tested all the software available. This is not a supported feature, and you take on some risk in doing it.

Understood, and good to point out. I've soldered chips onto motherboards and flashed various electronics for additional features, so I will in no way hold you responsible for anything that wouldn't work. I will, on the other hand, report back as to the findings of what worked / didn't if we pursue it. I'm more curious than anything else.

 

According to RivaTuners site, the latest version now supports XP-64 (Vista 64 in progress) and G9 series cards, so only time will tell.

 

Thanks for the help.

Great to hear.

 

Well, we have the 8800GTS SSC (640Mb) sitting in the IT dept now. We'll be benchmarking it with Cinebench in a Dell 3400 - 64bit soon. I'll post results with the card it has in it now (a Quadro 1700, I believe), along with the 8800 as is, and of course, after soft-mod.

 

Is there a better benchmarking app that I should test with other than Cinebench for testing the graphics cards / performance?

 

Thanks,

J

Not so much "better" as "different" - e.g., Specviewperf favors "pro" OpenGL cards very strongly, Cinebench somewhat, and then there are all these gamer benchmarks that don't use OpenGL at all. Your Cinebench performance will not have a very strong correlation to your Max performance. Your 8800 card will beat the 1700 in Max with or without the mod because Max doesn't use the Quadro as effectively as something like Maya or Solidworks.

 

Try this: http://www.spec.org/gwpg/apc.static/max9info.html

 

It's based on Max9 but there isn't all that difference between 9, 08 and 09 in terms is graphics performance.

OK: Report back #1

 

Specapc for Max is a 32 bit only app, and this machine for testing is strictly a 64bit XP right now. So, I went with Cinebench to at least see some numbers on it.

 

Machine is a Dell T3400

Intel Core 2 Extreme Q6850 @ 3.0GHz - Quadcore

4Gb RAM

The original card in it was a Quadro FX 1700

 

 

Since the only difference in Cinebench to observe for the video card is OpenGL. I'm only listing OpenGL shading here.

 

 

With the original Quadro FX 1700:

5918 CB-GFX

 

With the stock GeForce 8800GTS SSC / 640Mb:

5107 CB-GFX

 

With the softmod GeForce 8800GTS SSC (now seen as a Quadro FX 4600):

6416 CB-GFX

 

 

Obviously, I'm happy with those results. Next I would like to grab a second card and run them SLI and test again... Will also check the price on a 9600GT (RivaTuner now supports it as well) for kicks...

 

An EVGA 9600GT 1Gb card for $180... Hmmmmmmmm....

Thanks for the help on this.

 

 

By the way, this was the RivaTuner guide I followed: http://www.rage3d.com/board/showthread.php?t=33898714

 

 

Hopefully more to come.

ok eVGA is having a huge labor day sale and you can get some nice cards for cheap. SO if you want to try out the soft-mod on a inexpensive card, go go go go:

http://www.evga.com/articles/428.asp

 

256MB, 8800 GT, PCIe 2.0, D+D+HD $89.99

320MB, 8800GTS KO ACS3, PCI-E D+D+H $ 99.99

512MB, 8800 GT Dual Slot PCIe 2.0 $ 109.99

512MB, 8800 GT KO, PCIe 2.0, D+D+HD $ 99.99

 

Lots more too

OK, we picked up a GigaByte 9600GT 1Gb card to test. According to RivaTuner's description, the card is supported. Reading deeper, it's supported for overclocking, not for softmodding yet. Oh well, it's a fast card none the less.

 

Still need to test an SLI config on the 8800GTS (we just got the second card).

Mike, I wish I did. I was out on vacation last week. The system I've been testing on (a Dell T3400), didn't ship with an SLI bridge. We're (our IT dept) going to contact Dell today hopefully and get the story on obtaining one for that motherboard. I'll need that adapter to be able to compare the results to an SLI config of the 9600GTs as well, since the softmod doesn't work for them yet (or ever?). I will post back as soon as I have some numbers.

OK, we finally ran those tests. Riva Tuner, from what we were able to accomplish, doesn't support soft-modding in an SLI config, at least with the 8800GTS that we tested with.

 

We did hook up a pair of 8800GTS in SLI and compared that to an SLI config of 2 9600GTs though.

 

Cinebench 10 / OpenGL results were:

For ease of reading, I'm copying the prior results below and adding the GT:

----------------------------------------

 

With the original Quadro FX 1700 (for comparison):

5918 CB-GFX

 

 

With the stock GeForce 8800GTS SSC / 640Mb:

5107 CB-GFX

 

With the stock GeForce 8800GTS SSC / 640Mb - SLI Config:

6200 CB-GFX

 

 

With the stock GeForce 9600GT / 1Gb:

5303 CB-GFX

 

With the stock GeForce 9600GT / 1Gb - SLI Config:

6237 CB-GFX

 

 

With the softmod GeForce 8800GTS SSC (now seen as a Quadro FX 4600):

6416 CB-GFX

 

 

----------------------------------------

 

As you can see, the SLI config did improve performance by about 1000 points in either card, but not enough in either case to beat the single softmodded 8800GTS.

 

Looks like we're going with the 8800GTS.

 

Thanks for the input on this everyone.

I was having an issue with the nvidia geforce 8500 GT 512mb ddr2 card when using maya 2008-2009 the refresh in perspective vie was screwed and stopped from time to time so i installed the last riva tuner and made it to be recognized as a quadro card and now is working fine and have no issues with the viewport.

There's some bug between Revit and nVidia with OpenGL that's so odd I've given up on it completely. Let me know if you figure it out :) In the meantime, I'll reiterate what I've said several times:

 

REVIT USERS SHOULD BUY AN ATI VIDEO CARD. Preferably a FireGL - whatever the current one in the v3xxx or v5xxx series is.
