    Default Difference between GV-N56GOC-1GI graphics card revisions

    Hi Everyone,

    I have been using a GV-N56GOC-1GI graphics card for some time. It is a great card, and does a very good job of playing most games at medium to high settings. Recently I decided to try my hand at SLI so I bought a second card (from eBay), but I have just discovered that my original card is Rev 2.0, whereas the card that I just bought off eBay is Rev 1.0.

    Firstly can anybody tell me what the difference is between Revisions for this particular card? Secondly can anybody foresee problems with setting up SLI using these cards?

    Any help will be greatly appreciated.

    Kind Regards,

    It is unlikely that the different video card revisions will cause any problems.
    Adequate video card and case cooling is required.
    You will need a good quality 750 watt (or higher) power supply with four 6-pin video card connectors.
    Depending on your motherboard layout and slot usage, there might be issues with adequate air flow to one or both video cards.
    Do you already have an SLI connector for the video cards?

    Check out the Nvidia SLI guide, Introduction to SLI Technology | GeForce where they say:
    There are also very few restrictions regarding what GPUs can be grouped together in SLI: only the model and memory amounts have to match. For example, a GTX 580 with 1.5GB of memory could only be paired with another GTX 580 that has 1.5GB of memory, and a GTX 690 only with another GTX 690. Beyond that, manufacturers can be mixed (e.g. ASUS with MSI, EVGA with PNY,) clock speeds may vary (stock versus factory-overclocked,) the VGA BIOS for each card can be different, and no special drivers or software is required. Below is a chart with modern retail SLI-ready GeForce graphics cards, all of which are at least capable of 2-way SLI; specially marked GPUs can run in configurations of 3-way or 4-way SLI when proper requirements (motherboard, power supply, operating system) are met.
    I've had no trouble running an overclocked GTX 460 (1GB) SLI setup with my P35-DS4 and N650-DS4 overclocked systems using a Seasonic 660 watt power supply. My Antec TP-750 New power supply (made by Seasonic) also easily handled my SLI setup.

    You don't want to run your power supply at more than 80% of its rated power for extended periods of time, such as when gaming.

    Let us know how your SLI setup works out.

    Hello profJim,

    Thanks for your valuable insights, and taking the time to answer my post.

    I have an SLI connector, and I have almost finished testing my new (old) card using BurnIn Test - so far the card has performed fine.

    I currently have a 620 Watt Corsair PSU, which I am considering upgrading to an Intel 700 Watt PSU.

    I will write back with results once I have everything up and running.

    Kind Regards,
