    Hi all

    I am having difficulty finding out whether my SLI GPU is working or not. Here is my configuration:

    DELL XPS M1730
    Core 2 DUO T8300 @ 2.40 GHz
    2 Gb RAM
    Nvidia 8700M GT SLI 512 mb

    Here is why I think one of the two might not be working.

    When using GPU-z, it always shows SLI as DISABLED, even though I can select between two 8700M GT and the SLI in NVIDIA panel shows activated.

    Also, The SLI zone software just doesn't seem to detect that I have a SLI setup at all.

    When looking at advanced display settings, I show :

    Processor type : GeForce 8700M GT
    CNA : Integrated RAMDAC
    Card : GeForce 8700M GT
    BIOS information : Version 60.84.6a.0.6
    Total graphic memory available : 1023 Mb
    Dedicated video memory : 256 Mb
    System video memory : 0 Mb
    Shared system memory : 767 Mb

    I am wondering if dedicated video memory shouldn't be 512 mb when SLI is activated (2x256)

    Other than GPU-z showing two identical cards to select from, Hardware manager also shows 2 cards, one sitting at PCI BUS3 and the second at PCI BUS 4.

    I have looked in the BIOS and found no setting to change whatsoever.
    I have activated and deactivated often the SLI in NVIDIA panel, always resetting after changes, but the memory and all other parameters remain identical in both SLI activated and deactivated.

    I would like to know if there is one easy way to determine if both cards are fine and also if the memory numbers are normal with a 2x256mb card.

    I unfortunately do not have yet a game to test SLI configuration.

    Thank you all for your help!

    You could try running a program like 3dmark06, the test score should make it clear if the SLi configuration is working.
