Hey, i bought 2x GTX 275 SLI, and i installed them with the sli bridge, but i dont think they are wroking? i went to the Nvidia Control Panel Under SLI and Physx Configuration, and i set it to to Enable SLI ( Recommended)... but i dont think its working so guys is there a way to know if its working properly or not? becuase i used 3DMark06 and i tried the result both times, once with sli and once without sli, and both result = the same score almost..... so guys how do i fix this or ... what do i do, please help this my first time sli!, thanks for reading.

This is straight out of the Nvidia Control Panel Help section:

To verify that NVIDIA SLI technology is enabled and working From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Set SLI configuration. From the menu bar, click 3D Settings, then click the drop-down menu item Show SLI Visual Indicators.

The visual indicators will appear in games and will show whether or not SLI is running. Here is a link to a question at Nvidia's support section. It has pics and an explanation about the indicators. SLI

What game or games are you playing? Because a single GTX 275 will max almost all games without issue.

Um steady 60 isnt enough? It also depends on your Cpu, OS,PSU and amount of ram you have too. And 70-80 fps at 1650x1050 with 4x AA sounds about right. with a single GTX 275. Ok do you have dual cards option on in Cod 4?

Firstly check v-sync, secondly what are the rest of your specs and thirdly did you turn on dual cards in CoD4's options?

Hmm, maybe CoD4 doesn't use the cards effectively? Anyways, 70FPS is more than your eyes can tell anyway. Try a game like Crysis, you should get something like 50 FPS with no AA at that res.

Well check your bios and see if your sli is set on auto or on. Then make sure the sli bridge and power is all hooked up. Then make sure the video card is fully in the pci-e slot. Then reinstall the latest nvidia drivers and reboot then go to Nvidia control panel and see if your SLI is enabled.

One way to see if your getting the sli is to go to 3d settings on top of nvidia control panel and select show SLI Visual Indicator. If its there then its working.

If you are running vsync then you will not go above 60 fps. Also, COD 4 has a max fps of 90. I believe that you have to change some settings in the configuration files to get a higher fps. What games and benchmarks have you tried other than COD 4.
