GTX 550 Ti as a PhysX card

So on my smaller PC I have an HD 7950 now and I sold lots of my old stuff but I still have my GTX 550 Ti 2GB laying out so I figured what the hell, why not set it up as a dedicated PPU for PhysX games? I won't be playing a lot of bf3 on this PC but I will be playing more games with PhysX like Borderlands 2, ARMA 3, Metro 2033, and Metro Last Light(?). And in most games the 7950 seems a good bit under the 670, and the 7970 non GHz about equal overall (maybe a bit faster at this point in drivers actually), again the GTX 670 beats both in bf3 cuz it loves Kepler. But since I am not worried about bf3 for this rig I thought I might add PhysX and some OCing to the mix to bring it upwards of GTX 670 speeds for upcoming games.

Would this be possible with an AMD primary card and if so how?

hazle essentially has it correct. its possible with hacked drivers. just dont expect it to easily be set up, as users will normally encounter problems.

There is a way to do it. I actually didn't experience any problems that were not hardware related when I attempted it with my 6950 alongside a GT240.

The creator of the mod as well as myself found it worked most flawlessly and robustly with the 285.62 driver set. Here is how I did it.

-Install the graphics card (in your case the 550Ti) make sure the power supply is able to support it.

-Boot (duh)

-Let Windows install the drivers for the 550Ti, and then run the 285.62 driver set over it. You don't need the whole package, just the driver and the Physx. You can install the other stuff if you so please.

-WITHOUT REBOOTING run the 1.05ff mod, and it should patch. It might look a little funny, but it works.

-Reboot

-I would run GPU-Z to check that the Physx is actually operational. If it is, then the Physx box would be checked on the Physx part of GPU-Z.

-Happy gaming!

Absolutely do not installed the latest physx drivers, they barely even work as it is with only Nvidia cards installed. It bricks the use of any sort of dedicated physx so stay with the older driver. If anyone that was searching on the net stay with physx 9111107 version or older.

Thanks guys! Very helpful. I just used your links and instructions and got it all set up. I haven't gotten a chance to test it yet I had to leave. But when I rebooted after all setup PhysX was enabled in GPU-Z. Also I was very surprised this worked on my PSU, it's 530 watts running an HD 7950, GTX 550 Ti, and i5 3570K, all overclocked :) 

One more quick question when I open GPU-Z it tells me OpenCL is disabled? In a popup window. I thought this a little strange because my 7970s have OpenCL and they are very similar. It's been saying that since I built it.

530W?

Is it a good power supply?

I can see you getting away with that if your unit is one of those rare few models that can handle the higher loads. I would upgrade if I were you if your unit isn't one of the very high quality top tier models.

Euh......if it wasn't a Raidmax and something better I would say it would be alright. I would endorse a power supply upgrade though.

What are the best PSU companies do you think? I've only ever had two besides this one. I have an ABS Majesty 1100w Gold Certified in my main rig which has been absolutely amazing so far I've had it almost 7 months. And I had a Antec 450w which was very simple but seemed good quality for the time I used it.

Antec, Corsair, PC Power & Cooling, Seasonic, Silverstone, and XFX are among the best brands there are.

Sometimes Rosewill and OCZ also make some good ones.

Ok, cool thanks I will look into one of them. Until then I'll bring it all back to stock clocks and maybe underclock the 550 a little bit.
While I'm on the topic what do you think of that ABS Majesty 1100? Don't want it explode randomly in a $2000++ rig lol. The company doesn't seem to be well known but it had good reviews on newegg (yeah yeah ik don't trust them but nonetheless can be good to look at).

Well, its 80+ Gold Certified. You have to make a pretty good power supply to get a gold rating. And its a continuous power supply as well.

Not a bad power supply at all.

Ok cool, thanks again everyone!

Hybrid PhysX works great! Just tried it out on Metro 2033 on ultra with MSI AB OSD, 7950 ran full usage the whole time of course. The GTX 550 ran about 1-2% untill mutants were around it would go up to 5% and in the stations the highest I saw was 11% usage. So works pretty well! Only problem is becuase of airflow my 7950 runs ~10c hotter now @ ~73c loaded.

You should see higher usage than that even on that 550Ti but at least that you got a boost.

Any particular reason you can think of that I'm not?
Just FYI it is EVGA 2GB Superclocked version if that makes a diff..

Usually when people do dedicated cards they often get higher loads but most like my self use lower end cards like the 8800gt ect. What is your total system specs? Maybe you can get a little more out of it for a larger boost if there is a bottleneck that can be worked out.

Ditch that raidmax unit as it is a fire hazard, I rebuild power supplies every once in a while and cheap power supplies are almost always the worst. I highly suggest that you invest in something better. On the side, if you could afford such specs why can't you buy a decent psu for that rig?

Well it was right at my price cap when I got around to the PSU. I realize some say it is the most important part of the rig and I somewhat agree but due to my lack of quality PSU knowledge and 900+ 4 star ratings on Newegg, I figured it would be ok. Guess not.

Would it be better to just take the 550 out altogether and put my Antec 450 in it?

Well as I had said I rebuild power supplies and the cheap ones have the most problems. That raidmax is likely a 400w unit when temps come into play but that antec you can push it a little over its max. I still suggest that you look for a 600-650w bronze or silver rated unit for one of the best brands that are made by seasonic. When it comes to buying don't just look at the ratings but read the reviews and more importantly the complaints. The main problem with these cheap units if the caps going bad and the other is shorting.
