Kinda interesting... Cross SLIed?

This very old tricky already.....

Buy a mobo got 2 PCI-E slot then 1st PCI-E put ATI card as Main

the 2nd PCI-E Slot put NvidiaCard as Phyx

So any mobo chipset also can do that??? or they need nforce chipset only??

this "magic" only available in windows7.

how bout the nv+nv+crossfire board? does it work as well?

It works, also on Vista, coz its not SLI technically, the second card functions as a physX card, so CF board can be used as well.

you sure?

coz AFAIK.. vista onli allow one vendor driver for display at any one time.. if there is 2vga with different vendor (eg, ati & nvidia) the card not connected to vga will automatically be disabled by vista

yup, that's true, onli windows xp supports ati card + nvidia card for physix

I'm referring to Terrence's post, he was mentioning about using 2 nvidia cards on a CF board.
One nvidia card as gpu and one as physx card on a cf board.

only 9 series and above support PhysX or all can support?

I think 8600GT above with @ least 256MB should be can
I remember nVidia site say 8 series above with @ least 256MB supports PhysX

I was wonder if it on the P35 or P45 chipset mobo, with 2 PCI-E slot, can u use one card for physX & one main card for display???

I've tried it before but I couldn't get it to work and I don't have time to find a workaround. I do know Vista is a pain when you try to use both ATI and Nvidia card cause it will disable the 2nd card.

You can install the drivers on Windows XP and 7 without problems. Just that you have to look for a workaround to get Physx to work. Keep us posted if you try it.

Some body claim that Windows 7 driver model is WDM 1.1 and it is different version compare to WDM 1.0. The magic is still possible in Windows 7. I am looking forward to see this happens in Windows 7.

why u ppl need Nvidia to have PhyX??? actually in ATI there is supported PhyX... just benchmark never claim to read any result from it....

So...ATI itself will do.....

What?

ermm...i mean ATI does have PhyX supported already... but only benchmarking are not able to get any extra result from it...is it so??

correct me if i am wrong

wow so flexible.....

wow where did u get the info bout ati is physX supported?

@romulus

I've tried vista 64bit with 1 ati with a nv card.
Sadly to say it wasn't supported as only 1 driver allowed.

And that was b4.I'm just hoping sum1 will bring about the gud news bout
new driver will support or sumthing.

Erm, if you are using ATI card, it is your CPU's that's doing the calculations for physX, not your GPU.

@Terence573,

Please take note, when installing driver for nVidia. You must using Physic card driver. Not using normal forceware driver.

Have you tried?

8600GT and above claimed to have physx support. Still, my friend 8800gts 320mb doesn't have support for physx. Weird, it could be driver then.

Who says ATi has physx? ATi is taking advantage of gamers for it's AA performance and dx10.1.
If ATi has physx then it should support Nvidia CUDA for gpu folding in the first place.

wat is nVidia PhysX actually? today i realised it installed on my comp... wonder that is that.. coz im using ATI...

I don't see there is any reason to get another Geforce card for Physx unless you have a spare one. So far I don't see any significant impact with PhysX in any game... mirror edge is nice but you kinda forget it is there after a few hours of gameplay.

Cryostasis is forgettable also... boring game... zzz

physic processing unit...

ATi cards can do GPU folding way loooong time before NV.
X1000 series
btw, anyone remember this? read

ADD: anyway it's different from NV's PhysX.

that technology is far abandoned to for physics, seems like its forgotten by time.

anyone try use sli on crossfire board b4? if plug 2 nv card wat will happen?

This post has been edited by lms2005: May 7 2009, 10:46 PM

physics card driver?? means ageia driver?

if like tat never tried b4.

u still can use the sli gc but cannot do crossfire with other gc

even 8400gs has physX. Early G80 doesnt have physX, but after driver updates, it can be used as physX card.

SLI cannot be done on a CF board unless you are super pro that you know how to hack it. You can put 2 nv cards though, one as gpu and one as ppu.

it is not that they don't have physx. they just don't have capability to run cuda programming..

yea, thanks for fixing the sentence

physx is 4gettable...yes it is. But i tot all 8series card capable of handling cuda?

@Terence573,

Try the link below.

NVidia Phsyx driver

Let us know the result.

is it too bad just let the cpu do the job?

OIC is this one.
installed but also won't detect the geforce.
bad luck then....done in vista 64bit.

GPU manufactures are very clever making people to buy more than 1 card to get performance,As i know that ATI uses Havoc ann nvidia uses physx

Personal thought, waiting for ATI to implement Havoc using GC. Mind as well, wait for DirectX 11 that utilize Computer Shader (Similar to OpenCL) in next generation card. (RV870 and GT300).

With Intel owning Havoc now. It is gonna be hard to bring all Physic processing off CPU entirely. Havoc is still leading Physx now in terms of no of games support.

that one Havok...and they still developing it (last month they(amd) show it to public in order to counter the loud brought by nvidia)

Nope..you are wrong there

Physx -GPU can only be render by Nvidia and ageia ppu card

but Havok can be render by ati and nvidia card (and any graphic card that support opencl). Its a absolute win solution for end-user..

Technology has to start somewhere
Havok is a very basic, basic, basic form of physics compared to physX

havok physics is rendered by gpu or cpu?
nvidia wont buy ageia physX for nothing no?

ATI is working with Havok for Havok FX. Maybe this is the physic engine for ATI cards.

http://ati.amd.com/technology/crossfire/physics/index.html

One question: Which one is it better, to proses PhysX in GPU or CPU?
I am using C2Q6600 cpu and 8600GT GC...
Thx

if u download fluid demo by nvidia and u got a 8series card and above.
u can assume gpu physX is good when u toggle between gpu( hardware )/cpu( software ) rendering.
A huge gap performance between these 2.
But u could say nvidia's demo is biased...so the answer is not so precise.

Havok (openCL) will use both gpu and cpu...

i read somewhere that Havok will balance the processing performance between gpu & cpu.
lets say if GPU perf> CPU perf.. then more workload on GPU...but if CPU perf > GPU perf... more workload on CPU (heck..i don't know how Havok will decide it in reality )

imo...ageia nearly die..so nvidia bought it ... and to make their card super special awesome while it is not.. lol

lets see..

Physx codded for CPU : it will always run on cpu, and will not run on gpu..
Physx codded for GPU : it runs better on gpu, and runs lolsome/terrible on CPU..

the list of games that have GPU-Physx : http://technologic.ysoserius.com/2009/04/l...x-game-for.html

other than listed so far..they will only run on CPU , not GPU.

3dmark vantage is out of equation...since it is not game.

So, have anybody successfully done it? Care to share?

haha...ya i am using 3870x2 with dedicated nvidia gtx260 as my physx adapter....knowing that 3870x2 performed poorer than gtx260... i still like the way it heat up my whole room like doing sauna...

windows : windows 7
motherboard : DKA790GX platinum
processor : athlon II x4 620
catalyst : 10.1
forceware : 191.07

i willing to help ya... as wan u all don waste up ur spare physx powered nvidia cards...

Attached thumbnail(s)

shud update ur nvidia version to 195.62

haha thank for ur advice ya... tried before... physx been disabled that time so just move back to older and stable nvidia driver...

anyone can help me guide this thinking of using my 8800gt as physiX card with my coming soon ati card.

Woah, what a waste Technically a 8600GT is sufficient already as all the PhysX supported games out there does not require heavy physics calculations.
Use your ATI card as main output and your 8800GT as secondary. Install both drivers and enable 8800GT as dedicated PhysX card in NVIDIA control panel.




And yes, PhysX is a much more powerful physics engine compared to Havok. Last I heard, PhysX is used in more advanced simulation programmes than games.

no need special driver for nvidia my fren?

Read this. It's a guide on how-to do this.

This post has been edited by Silverfire: Feb 15 2010, 05:43 AM

not exactly.

i did come by some article that did a test and found that going for cards like 9600GT for Physx does show more improvement in framerates.

Dedicated PPU as well?

just by anychance is it possible to do it with 1 monitorr....

I tried with ATI act as Display card and nVidia 8800GTS as Physx card. Working fine. Just the GPU-Z give me wrong info after that.

Well, basically, it is just for gaming purposes. Nothing special.

Thinking between Crossfire my system better or this kind of setup for next GC card upgrade.

now there's a hydra chip to do the magic.

did u try out any game that support physx? or it was grey out option?

@Terence573,

I didn't really hopes Hydra chip can play any important role at the moment, it is just still new. It is good idea.

I tried Mirror's Edge, so far so good.

Just wonder what game can see more Physx effect?

batman arkham asylum?
tried?


btw, it can be done on single monitor too right?

the nvidia card will only gives physx for some games, and will not give any extra fps in other game right?

@stereokumonomu,

At the moment, I got no time to go for Batman Arkham Asylum.

I am using 2 monitors (each monitor connected one display card.)

I received couple of PM about the workable solution on the ATI + nVidia Physx solution. Below is my reply and hopes that would help some other people.

The forum is in chinese words

can translate with google

http://translate.google.com/translate?js=y...&sl=en&tl=zh-CN

thank you for ur advice... the 8600gt physx engine is not powerful enough for the new physx powered game such as batman akhlam asylum and nurien demo...as i run the physx benchmark test, the score is not high enough with gtx260 too... gtx260 with dedicated 9800gtx as physx adapter would be recommended for high setting of physx in batman A.A .. another game like cryostasis needed heavy physx calculating too... in high physx setting.. thank you

Added on February 22, 2010, 1:39 pmya i am using one monitor too.... u connect ur ati card ( primary adapter ) to the dvi port... nvidia ( secondary adapter ) to vga port....this is to bluff the nvidia card that u are using it.... without connecting the nvidia card to monitor, ur nvidia control panel would be disabled and never could open to enable the physx...of course u need to apply a patch first

This post has been edited by kimchoo: Feb 22 2010, 01:39 PM

theres a guide on the internet on how to do it with single monitor...involves a DVI-VGA dongle and some resistors....easily done...google and see

Added on February 22, 2010, 2:59 pmoh.... n 8600GT not enough for PhysX?

sure ah? on nvidia says its practically the minimum....and before that the minimum was even a lower card but they changed

This post has been edited by mADmAN: Feb 22 2010, 02:59 PM

oh dear, i hv just bought a used 8600GT with the intention of running physx.

What's your main card?

4890. soon gonna CF

So 4890 Crossfire + 8600GT as PhsyX? A few FPS(1~3) wouldn't affect anything with your specs, I guess.

can we use sli by using different type of nvidia cards ?

You can't. For SLI, same model only.

sorry guy i didnt understand well how to make physix setup..so can i ask abit bout physix setup and need ur help

i got 5850 as main and 88gt as physix.
but prob now i need to run main card at 2nd slot while physix at 1st slot..izzit ok?
while installing the main card driver(ati) shud i plug in both card in their slot?or need 1 by 1?abit confius
the physix card must plug the cable to monitor to enable the physix?or can let it be w/o connect to monitor?

ive tried plug in slot both card and wanna start install ati driver 1st..but i can get any signal from the ati card
so abit unclear bout how to start the setup..been read in forum but didnt found they stated mush put main card only or can put both and need to slot one by one after done installed driver one by one..thx for ur help

Bro..here some tips:
Would be better do this on fresh windows installation,make sure to download the patch and new forceware.(depend on the GC as well as the patch)
Here's The Link:
http://www.ngohq.com/graphic-cards/17706-h...03-v1-04ff.html

1-Plug ur main GC (ATI)on the pci-x16
2-Then ur nvidia GC on pci-x4 enough already.
3-Then log to ur windows and start installation
4-Install ur ATI catalys 1st then reboot
5-Then install nvidia forceware reboot
6-Then log windows into safe mode press F8
7-Use then GenL patch,patch it then reboot
8-Log in to windows,go to screen resolution - detect - click on the nvidia
adapter extend it.
9-Go to the nvidia - physx section - enable
10-Then run fluidmark for physx testing..

I have tested on my AMD RIG which use XFX 6850 + ZOTAC 9600GT,
1st time i have no idea that the GC is working.Then i try to reformat back my pc the thing already ok..
Note:Do not patch it to many times.
