[HELP] SLI questions..

1. No I don't think it matters which card yo use. If it does, use the first one, whichever that is.
   
2. It may not detect SLI straight off the bat, but once you install NVIDIA drivers SLI should work.
   
   
   All you have to do to enter the NVIDIA control panel is right click in the empty space on your desktop and select the NVIDIA control panel there. Once you open the NVIDIA control panel you will see a screen like the image below. You will want to click the icon for 3D Settings.
   
   After you open the 3D Settings box (see below), you will see a link that says Set SLI Configuration on the screen under a bar labeled performance. Click the link to enter the Set SLI Configuration area.
   If your settings already show Enable SLI Technology selected, you don't have to go any further.
   If your settings show Do Not Use SLI Technology, you will need to click the button beside the link labeled Enable SLI Technology. Once you click the enable button a box will appear in the bottom right corner of the screen that says "Apply", you will need to click that apply button to save the settings and enable SLI.
3. All video cards rely on main ram a little bit, but dedicated video memory is so much faster than sharing the main ram that it's not much to consider IMO.
   
4. Not that I know of. In fact, when you enter your cd key it gets fused to your motherboard and cpu. If you upgrade your motherboard, you've got to call up MS and tell them this so that you can get your key released. There are two types of keys, one is OEM, the one that locks onto a machine, the other doesn't but I can't remember the name.

1. No, as long as it's set as the primary.
2. I believe you have to enable it through the software given by the manufacturer.
3. Not really, they should have their own.
4. No. If you try to activate it on both computers, it will deactivate the other one.

Sniped. :P

Hey guys!
Again I'm turning to this forum after the great support I've got the last times needing help.. this time however, it's about SLI.
The computer will come prebuilt from the site I ordered from, with no OS, I already have Win7 Pro 64-bit. The questions are as followed..

1. Does It matter which card you connect the monitor to?
2. Does Win7 detect SLI, or does it need to be enabled through win/nvidia UI?
3. Do the cards rely on the "main" RAM at all?
and another one i just thought of..
4. Can I have 2 PC's running the same Win7 key for private use?

[EDIT] The two cards are PointofView GTX 285

1) The monitor must be connected to the card in the first PCI-E slot when SLI is enabled. The card in the secondary PCI-E slot has its output ports disabled, so no monitor will be able to be connected to this card.

2) You need the Nvidia drivers installed for SLI to be detected. Once the drivers are installed, you will get a notification saying you have an SLI capable system and will let you enable SLI in the Nvidia Control Panel.

3) They don't rely on it, but will use it if the video card RAM is being heavily used. Remember though with SLI, you don't double your video RAM with your graphic cards, you still only have the amount of RAM that's on your primary video card.

4) Like what's been said, you can only use one product key per computer.

It's usually the one closest to the top of the case, yes.
