If you had, say, 5 Titans, then yes. While Crossfire and SLI may only go up to 4, the number of GPUs hooked into a system can in theory be as high as the number of PCI-e lanes in said system. As far as programs that use GPGPU are concerned, it'll just load balance on all available GPUs.

Under Crossfire/SLI, the GPUs are shown to the OS formally as one GPU. This does not stop you from adding another GPU, or even adding 4 more if you like and running 2 banks of Quad-fire/SLI (though good luck supporting that driver side), and using software to allow for screen merging.

A PhysX card is outside the standard quad-bank, and thus can do whatever.


According to these folks it is still alive and being updated: as of june,

http://www.ngohq.com/graphic-cards/22136-how-to-fix-hybrid-physx-with-latest-physx-and-geforce-285-solved.html

1. First! Download below and Run PreHybrd.exe to prepare your system. It installs PhysXv2.729 and cleans up and replaces old files. It will clear legacy files so within the GeForce driver the PhysX.msi(folder) will install the latest. (If you run it again later accidentally you will have to install PhysX.msi and run Hybridiz.exe again!) This step was added since PhysXv9.12.0807 stopped containing most DLLs for under v2.7.3 support. You should never need to run it again, and it will never be updated beyond this original 2.7.2.9 version number.

2. Install four latest drivers from:
BOTH:
A.
13.5cap1 profiles AND
B.
ATi Catalyst v13.6 Win7/8 OR v13.4 XP64 OR XP32
AND BOTH:
C.
PhysX: v9.13.0325 AND ......

Well, I have one slot left in my computer after installing my ZxR... I wonder if PCI-e 2.0 x4 is enough for a PhysX card...

Link to the post with the directions? I think I can swing grabbing a 640 or something.

x4 is most def enough for a PhysX card, in fact if you plug a 7970 in an x4 slot, you will only lose 4-7% (or less) of performance.
You can actually run a PhysX card in a x1 slot if you had to. I was running 3x7970 + a GT 640 about six months ago and the 384 Cuda cores handled the physX nicely.

before someone says it, I have done it on numerous occasions and its fact
a bit of reading and benching on the subject

Well I can say the 8350's run hotter than that on the stock cooler at stock settings running blend.
My specific chip was barely within thermals. I'd assume the 8320's follow suit.
I wouldn't attempt any sort of oc on the stock heatsink/fan.

43core is not bad if we're talking blend or largeft.

That is about right if you have 'normal' ambient temps (22c +/-)
why? are you concerned about 43c core Miller?

I like HWiNFO64, and I've managed to get it to show CPU temp and load in the system tray, but can't see a way to have it add those temp icons at boot ?

That's why I like Coretemp, set and forget, usually lol and it sticks the temp and load in the system tray at boot, most of the time smile.gif

In other news, the missus is away to the town as I speak, she's going to ask in the hardware shop if they have any 600-2000 grit sandpaper, if they do, it's lapping day biggrin.gif

I am because I'm running aftermarket air cooler (cooler master Gemini s524) and haven't touched over clocking yet. I live in Hawaii and don't have air-conditioning and its summer Lol ambient is in the 80's my house is 90's (Fahrenheit)

I dont think it matters on anything other than custom loops, it wont really help you get over voltage wall at 4.9-5GHz anyways.
