Adding a PhysX card to 2 x HD6950s? - Page 5

post #41 of 53
This is too long to read all of, but you can't just throw the nvidia card in and get it to work. There is a software hack you have to use, which I eventually gave up on because it was insanely annoying trying to get it to work.
Meh >.<

Sent you the files I used and a brief explenation. Do so at your own risk though! REad up a bit more on the net before you do it too. Knowledge is power

the 9500 would slow down your rig.

there were some reviews that had a 580 running physx and it needed at least a 560ti in order to at least be comparable to running a single 580.

YEah a couple of other people have said that and kindly linked a couple of guides of how to do it. It was just a thought that now I feel like I want to do just because it's possible ha

Haha, I feel the same way. I want to do it just because I can!

It seems to me these days that a dedicated card is only worth it to people with ATI cards who are locked out from it, ironically. It sounds like the higher end 500-series, and even 400 series cards are powerful enough to run PhysX without a dedicated card, especially in SLI setups.

Here's a really good in-depth review on the GTS 450 from here on OCN. Its compared to the 460 and 470 as well, and even shown running as a dedicated PhysX card in Batman AA and Mafia II, though only with a GTX 470 as the main card. Just to give you an idea of general performance expectations. Also, I can't seem to find much information about running Crossfire ATIs + nVidia Physx, except that's its possible, and could have issues, as has already been mentioned in this thread.

It's possible, no hitch no glitch. I have been running with Quad setup + PPU for years. There's a new patch work in progress to anticipate for the next 6xx series as a dedicated PysX. The new patch looks promising though.

This is all you have to do:

1. Install Forceware 258.96 > don't restart.
2. Install PhysX System Software (.916) > don't restart
3. Run the Patch > restart PC.

Verify using GPU-Z, if PhysX is checked, it works everywhere. Nothing more you need to do.

Good thread and conversation ...

can I get in on it ? as I was planning on doing similar, I recently bought the Sapphire TOXIC HD-6950, unlocked and OC'd it more so it's essentially a 6970 ... and I had an old nVidia PNY 9800GTX+ card sitting in a draw that I was going to put in alongside the TOXIC for use as a PhysX card ... would that be a GOOD combo ? or would it be too old / slow of a card for PhysX and slow the FPS down ? and I think my PSU should handle both cards right ? a BFG LS-680 watt.

Unlocked 6970 + 9800GTX = perfect combination. Give it a try, it's not you are going out to buy one for this purpose. If you are into PhysX games, use it. PSU no problem.

You can put it in now and do the simple 3 steps above and done.

Gotta say it mate you the man when it comes to this stuff!
I've still no tgot a card yet though! Waiting for a good second hand one from a well known auction site Cheers for all the help though!

Oh one thing forgot to mention, if you don't utilize/need the card to do anything in the background, there's an option to put the NV card to sleep to save power consumption

Go into Control Panel > Power Options > Change plan settings > Change advanced power settings > select your options.

Or in Device Manager under Display adapters, disable the PhysX card
