    currently only playing darkfall MMO which SLI is not supported with my vid card (m9750 alienware 7950 gtx SLI)

    I have 4 gigs installed, currently 2.5'ish showing as system memory. Anyone remove their 2nd card for a non-sli game for the extra memory? and would it be worth the performance boost?

    Ya I doubt it would provide any performance boost what-so-ever.

    I agree that it shouldn't require physical removal to do this, and that either way, it just doesn't matter that much.

    sorry for the lack of details.

    os vista 32 I do have a copy of vista 64 but the m9750 cpu/motherboard will not address memory above 4gb

    doesnt seem to matter tho- I removed the daughter card after I couldnt get a change in system memory from disable/uninstall the 2nd card and the notebook would boot but I had a black screen, even tried a external monitor.

    It's still Vista32 causing the issue. 32bit operating systems have to map hardware addresses into 4GB of address space, along with the system memory. Even if your system only physically supports 4GB of RAM, a 64bit OS maps the devices to a much higher address, and will give you access to all of your installed memory.
