The Dedicated PhysX card FAQ - Read this before asking any questions!

Have you tried using your 3rd slot. I know it is only a 8x but really that should make almost no difference just for physx crunching.

 

i only have 2x 16x slots and one x4 slot besides the usual x1... cant do that sadly!

 

oh I wasn't sure which pc in your specs. Asus M4A89GTD PRO was what i looked into.

 

thats right, it has 2 slots

 

Is the board on the latest BIOS?
Can you fit a full-length card in the x4 slot? PhysX cards don't need a lot of bandwidth and a x4 slot would do just fine.

 

yes, tried the third newest and newest bios, doesnt change a bit. sadly no, i would need to cut a slot in the x4 pcie to use it

 

Have you contacted Asus? Something just doesn't seem right here...

 

actually i havent, i can see where you are leading, and i also think it may be a compatibility issue plus a missing bios option... do you think they can do something about that? may have to look up the phone numbers

 

I have just bought a GT240 for physx, I will not have to figure out how to cut my top PCIex X1 slot open so a full X16 will fit.

Hope to get 6950's Xfire'd with GT240 Physx

 

you can also try to trim the card itself, there was actually a very nice tut here on the forums

Hi,

just for entertainment this Sunday i will install an old single-slot GF GT9600XXX as Physix card alongside my brand new 670. I know for most games this would be needless, but maybe some of the stress-fullest games can take advantage of it.

Nvidia recently released a "Physix Benchmark": http://www.geforce.com/whats-new/ar...nload-the-pla-directx-11-and-physx-benchmark/

Now, I also have some questions, forgive the simpleness, but it is just to make sure the following:

1) This physix only card would need
a) its fan spinning ?
b) the additional power plugs plugged in ?

2) Apart from the above-mentioned benchmark application, what is the best real game to test if the 670 handles well on it's own or better with the 9600 helping?

I will test, but maybe the community already has...

THANKS!!

 

Testing, so far. (will edit)

A) GF9600 as dedicated Physix, PCIE power cables not connected.
Get lack of power warning on boot.
Nvidia panel recognizes card, set to do Physix
Running this chinese PLA benchmark, says no physix, and physix graph overlay says CPU, so apparantly I get no Physix from the GF9600 GPU.
Results
Media 90
Max 124 FPS

B) Reboot and adding power cables...
No more power warning.
PLA still says no Physix in its options. Running with Physixs=CPU bar...
Media 103
Max 135 FPS...

Maybe gotta test with a proper benchmark software...

 

Erocker: Fluidmark 1.5 seems to be working with 6xx cards now...

It is hard to download, I got it from x-drivers.ru


Fluid mark 1.5 Results:
With dedicated GT9600XXX
- "Score" 321
- 26 SPS/FPS

Without dedicated card, just the GTX670
- "Score" 1167
- 96 SPS/FPS

Weird, and for sure it is not optimized or maybe it is buggy, but then GAMES ARE ALSO NOT ALWAYS OPTIMIZED, so this is a very negative relative result.

Add to that that the extra 9600 card eats some wattage, adds noise and tons of heat right in the mouth of the GTX670, and the results are negative:

9600 is out of the rig.

 

So....this card : Gigabyte GV N430-1GI (rev. 2.0) - GF GT 430 - 1 GB
should be sufficient to run - say the Borderlands 2 game alongside a 7970?

Question is - will it run on a Crosshair IV Formula? - Is it worth doing it?
The GT430 is a leftover from a friends upgrade......

 

So I am having issues getting this to work. I cut down my card and it was flawlessly in a PCIex x1 slot but when I install the Nvidia drivers and reboot it kills the AMD drivers to the point I have to uninstall and use driver sweeper before they will reinstall properly. What am I doing wrong?

AMD drivers 12.8 and Nvidia 258.96

 

You need this http://www.ngohq.com/graphic-cards/17706-hybrid-physx-mod-v1-03-v1-05ff.html
And older drivers 285.62 I think.
Nvidia blocks PhysX with Ati hardware present

Borderlands 2 wont utiliez the gpu even after deleting the PhysXDevice.dll

 

Got physx working with those drivers! Also got physx in BL2 and OMG is it wonderful!

Use this setting

MSI afterburner shows load on all three cards and CPU load is around 10%

 

so you have that other card in the PCI E1 slot

 

Yes

 

cool, i can only guess Physx only requires the x1 bandwidth and nothing more?

 

some update about this I guess.

Members are sk3tch and staypuft on EVGA forums that decided to run some test for some fun

Advice needed from those with hyrbid physx

Just wanting a quick word of advice really I've got chance of swapping my old old old 9500GT for a somewhat newer 8800GT but is getting around all the workarounds to enable PhysX with AMD as main GPU worth while with the 8800GT?

I'd like to know if others have got any results that I could compare or just advice in general.

EDIT! Whoops! Somehow I made 2 threads of the same in seconds.. could a mod delete one please.

 

the 8800GT is overall faster card
