Running ATi with Nvidia on the same motherboard?HOW?

post #1 of 8
Thread Starter 

hello,

i read it somewhere that one can run ATi/amd and nvidia gpu in the same system.

the ATi/AMD gpu being the primary gpu and Nvidia for pHysix.

 

1.i currently have a xfx amd 6770 1gb running.

2.i also have a 'very old' xfx nvidia 8500gt.

3.my motherboard only supports x-fire.(i know no ribbion is required for the above setup,still i thought u should know.)

the slot for a second gpu is at x4 as compared to the first gpu slot at x16.

4.also the 8500gt is very old and crashes quite a lot(i guess new TIM would help.)

 

my questions.

1.Is it worth it?

2.How to do it(i saw forums here on OCN but they are from 2009,i guess things may have changed now)

3.Since my 8500gt is very old,if it crashes..will my whole system crash or the card on its own will recover and ask for  a restart(i would hate it if my PC freezes between games or while i work on maya.)

1. It is entirely upto you and nobody is going to change your personal preferences.

 

2. Very easy and nothing has changed. Check this thread http://www.overclock.net/t/591872/how-to-run-physx-in-windows-7-with-ati-cards/1050#post_15472355

 

3. In short, YMMV.

Running a Nvidia graphics card to do Physx in an x4 slot is not a problem at all. Even a powerful card like a GTS285 only suffers minimally. See the chart below.
322

The critical problem is not that the 8500GT is too old but it just does not have enough shaders. Nvidia has stated a minimum of 32 but the 8500GT has only 16.
Quote:
Which graphics cards can accelerate NVIDIA PhysX?
All GeForce 8 series graphics cards and above with at least 256MB of local onboard graphics memory and at least 32 cores will be able to accelerate NVIDIA PhysX. If you intend to use an NVIDIA supported graphics card as a dedicated Physx card, the other graphics cards in the system must also use an NVIDIA GPU.
http://www.geforce.com/Hardware/Technologies/physx/faq


A simple chart below will give you a general idea:-
425

Summarily, it is not recommended.

your main GPU is too fast and the nvidia card will only slow it down. with your card a dedicated physx isnt really needed

thanks for the link.

but since 8500gt is too slow,i would rather not use it.

moreover during its last days,the 8500 used to crash a lot..i dont want that :)

thanks again!
