Thanks

That's all I was looking for.
I'll get the 4GB version then and wrap this 590 up in Christmas paper for the kids.

SKUD

Skud, any indication when the 4gig will become available?

MY 580s in SLI work ok with cLOD although I'm only using one card for graphics, then other for physics engine. :grin:

As far as I know ClOD does not support physics either, so basically you are running it on a single card.

Internet Rumors say May. So expect June-July. 685 in October so expect Christmas or 1st qtr next year.

is that 680 4Gb or 690 4Gb?

From 25-30 FPS to 50-60 FPS is a 100% increase in FPS...;)
As far as I know, Luthier expected an increase of "ONLY" 50% in FPS and 50% of 25-30 FPS would be ca 12,5-15 FPS more compared to what you have now ;)... So after the patch you should be looking at 35-45 FPS AT BEST!.. Still significant though!!

Just saying!:grin:

For what I can judge the SLI for two GeForce gfx580 1.5go ddr5 works without any problem. It is what I have in my PC.:cool:

That's not true, Nvidia won't support it until the bugs are fixed

You can force it but its never worked properly

That should be possible.

According to the nVidia docs, you can query this via NVCPL.DLL (liked to documentation).

The call to be used is NvCplGetDataInt() (page 67), with the argument NVCPL_API_NUMBER_OF_SLI_GPUS or NVCPL_API_SLI_MULTI_GPU_RENDERING_MODE you should obtain the information required.

In oder to access this information, you'll need P/Invoke. If it is OK to statistically link NVCPL.DLL you just have to create the correct import (static external method) and you're fine. Otherwise, you can also choose the LoadLibrary and GetEntryPoint way and use the Marshal class to create an instance of a delegate (declared with the correct arguments) which represents the function to be called.

Edit: The following snippet may get you started (I don't have a nVidia card though, so that's completely untested and on your own risk ;) ):

Code:

public const int NVCPL_API_NUMBER_OF_GPUS =7;    // Graphics card number of GPUs. 

public const int NVCPL_API_NUMBER_OF_SLI_GPUS = 8;    // Graphics card number of SLI GPU clusters available. 

public const int NVCPL_API_SLI_MULTI_GPU_RENDERING_MODE = 9;    // Get/Set SLI multi-GPU redering mode.  



[DllImport("NVCPL.DLL", CallingConvention=CallingConvention.Cdecl)]

public static extern bool nvCplGetDataInt([In] int lFlag, [Out] out int plInfo);



public static void Main()       {

        int sliGpuCount;

        if (nvCplGetDataInt(NVCPL_API_NUMBER_OF_SLI_GPUS, out sliGpuCount)) {

                // we got the result

                Console.WriteLine(string.Format("SLI GPU present: {0}", sliGpuCount));

        } else {

                // something did go wrong

                Console.WriteLine("Failed to query NV data");

        }

}
