[OUT OF DATE]How To: Run PhysX in Windows 7 with ATi Cards - Page 104

post #1031 of 1230
Hi guys, I chanced upon this thread when I was searching if it was possible to run PhysX on ATI cards (the recent Batman AC PhysX demo video was rather impressive!).

My setup is a Asus Sabretooth P67 and 2 x Sapphire 6950 CF. I have a spare 9800GT lying in my old PC, so am thinking about doing this. All I have to do is install the 9800GT in 1 of the empty PCI-E slots and follow the instructions and I'm good to go?

A bit concerned about power usage and heat though..I'm on a FSP Aurum 750w and am not sure if there will be enough juice to power 3 graphic cards...

You are all set.

PSU can handle it.

Make sure the third PCIe running at least x4 for 9800GT to work.

Follow the 3 steps and you are good to go:
1. Install Forceware 258.96 - don't restart.
2. Install PhysX SS (.514) - don't restart.
3. Run the patch - restart PC.

Verify with GPU-Z if PhysX is checked, you have done it right.

As one member here keeps reminding "Keep it Simple".

Thanks so much Wali. I'm gonna give it a shot as soon as I get back from the office.

One question though, how do I make sure the 9800GT PCI-e slot is running at x4? Is it a setting I can change in the BIOS? I know that the slots which the 2 CF cards are sitting on are running two 8x, but as for the normal PCI-e slot, I'm not not so sure.

There are 2 ways:

1. Use GPU-Z and it will show the PCIe lanes assigned to it and make sure it is not greyed out (hardware limited).
2. In Device Manager, under Display Adapters, make sure there is no error messages with that yellow inverted delta symbol. If the adapter is "disabled", you are hardware limited by PCIe bandwidth.

I'm certain there are no yellow error symbols in my Device Manager. Will have to check GPU-Z though, I have the application but never really delved into it much.

I'll post updates if this little experiment works!

If you are not hardware limited and incompatibilty issues with your board, bet bottom dollars it will work.

Fiddled around but because of the huge fan and heatsink of my Asus 9800GT, it can't fit into the only PCI-e slot of my motherboard.

There goes my hopes of running a dedicated card. Anyone tried exploring with the hacked drivers which allows ATI cards to run PhysX using software?

Hey all I am in need of some help. I have two 6950's in crossfire and installed a gtx 550 ti for physx. The problem I am having is when I have the 6950's both physically installed along with the 550 batman and mafia (the two games I've tested so far) run extremely slow with physx on or off. When I take out one 6950 and only have a single 6950 installed along with the 550 those two games run smoothly with physx enabled.

It can't be power draw because I have a 750w psu and when using a killowatt meter it shows only 350w being drawn with all 3 cards installed and active. Even with crossfire disabled I get the same issue so it has something to do with having all 3 cards installed. I don't really understand why though, it doesn't make sense to me.

I've tried uninstalling all drivers, ati, nvidia and physx. I installed 11.9 cats along with latest caps, then after reboot installed 280 forceware and 621 physx drivers and of course the 1.04ff patch. Any help would be greatly appreciated.

I think I figured it out. The cards have be in certain PCI-E slots so I reconfigured them but now I get blue dots all over on anything with a dark background. The cards are fine because I took out the 550 and put the 6950's in their original slots which gives 16x link and no more blue dots. This is very frustrating.
