I have been trying for the past days to get 2 GeForce 670 GTX cards to work in SLI on my Precision T7500.
I have the cards installed on PCIe SLOT2 and SLOT4, and connected through a standard SLI bridge from ASUS. I have also configured the BIOS Video as "Option 1".
Both cards are recognized. The system boots. I can connect the video cable to either card and it works. I can also see both cards on Windows Device Manager, and on nVidea Control Panel. However, I don't have any SLI settings there. I have run numerous tests and confirmed that SLI is in fact not working. I am using the latest 304 driver release from nVidea.
What am I missing? Can you please help me out?
Welcome to the Community.
As explained by you it seems your computer meets pretty much all the configuration needs for SLI to work on your machine. However, we have not tried SLI bridge from ASUS, on our Dell Machines. Kindly check on this part and keep us posted.
Further, you can check the following link from Nvidia website for all your FAQ's on SLI:

Since the GPUs themselves were not sold with a SLI bridge I had to obtain one separately. Unfortunately I have no way of testing if the bridge itself works ATM. But given your reply, could you please tell me which ones have been verified to work? Does DELL sell them as well?
Thanks again for your reply.
Sorry for the delayed reply. If you are interested in buying an SLI Bridge from Dell you can contact our Spare Parts Sales team. In order to contact them do visit our official website (www.dell.com) and from there select your region from the top left side of the page. Next you will see a Contact Number on the top right side of the page, you can call this Number and they will help you with the correct part for your machine.
Thank you. I will try that as soon as possible and post my findings here once I receive the part.
Your reply seems to indicate that the T7500 motherboard supports SLI.
Can you confirm that? I read somewhere a thread that indicated that the chipset used in the T7500 does NOT support SLI.
Thanks for any updates, as I am experiencing problems trying to hook up two ASUS GTX780 on myT7500 without any "SLI" success so far. Both cards work simultaneously (can connect monitors to any of them), but the SLI item does not show up in the NVIIA Control Panel
The T7500 has:
Support for 2 PCI Express x16 Gen 2 graphics cards up to 225 watts
1100 watts 88% (80 Plus® Silver Certified) efficient Power Factor Correcting (PFC) power supply

SLI is not listed as a feature.

Can any one tell me if the SLI riser card # TK025 from a T4400 will work for the T7500?
