2x 580GTX better on 3.0 or 3.2 ? Tweet

[MagnusL3D]

Well I just got 2x 580GTX and with the new release I wondering is it better to run the Cuda 3.2 or the Cuda 3.0 release ?

you should stay with 3.0 so you can use both of them and wait for 1.25 for the 20% extra

We have explained the situation in the release notes, but why are you reluctant to upgrade. Beta 2.42 CUDA 3.0 is not slower than beta 2.3 v5.

Sorry if this is answered somewhere already but I didnt find it, do I need the Cuda 3.0 drivers installed for the Octane Cuda 3.0 version to work with 2 Cards ?

Because I have 266.58 (released Jan 18) installed and with that came Cuda 3.2.1, and starting both Octane Cuda ver 3.0 and 3.2 says both cards are active.

Again, sorry if it already was answered somewhere.

Every program uses the versions which are involved with it.
You can have a DX11 card, but if the game uses DX9, you have DX9.
You want MultiGPU? Then use Octane for version cuda3.0.
In that version, the cudart.dll v3.0 is in it and Octane use that.

Well yes I know I was just perplexed since both Octane with Cuda 3.0 and Cuda 3.2 reports both my 580GTX being active. And getting the exact same render speeds. I have SLI disabled etc. But hey it's still faster than previous versions so..

Ok, thats strange, because 2x 2/3 cores should be faster than 1x 3/3 cores

Yup that's why I'm wondering because I must have certainly done something wrong Also GPU-Z reports Card 1 at 90% load and Card 2 at around 15-20% load with both the Cuda 3.0 and 3.2 version. Maybe I should just restart the computer between installing new drivers and disabling SLI ?
