Mutliple gt520 video cards

Forum Graphics & Displays : Nvidia Mutliple gt520 video cards

Hi,

I have 2 EVGA GT520 cards, each with 2GB. My goal is to drive 3 monitors. My MB is an ASUS P8Z68-V LE. I can get 2 monitors working fine on the same card, but the third monitor is not recognized. What am I missing?
TIA!
Lee

Two are on one card and the third is on the second GT520? How are they connected?

All of the monitors are connected via DVI. The cards themselves are in the PCI Express slots of the MB.

When you go into the Nvidia control pannel are all three monitors recognized? In the set up multiple displays have you enabled all the displays? Are all three in the box to be checked off and do you see the three screens in the next box? If it is not recognized then in between the two boxes there is an option to click on that says , "My display is not shown..." , if you click on that then you can force recognize the third monitor.

Only 2 monitors are recognized, and they are both on the same card. I tried the "Rigorous Display Detection" function and it still didn't find the 3rd monitor.

What are you using for a connection for the third monitor? What are the options for ports on the second card?

The third monitor is DVI as well. Each card has 2 DVI and 1 mini HDMI outputs.

Have you tried switching around DVI ports with all three monitors?

Yep..Just tried that. Whichever monitor is on the second card is not recognized.

I know it might be a lot of work to keep trying different things but I guess at this point it is your only option unless somebody posts with an exact answer for you. Have you tried switching the cards from one slot to another to see if it could be the card itself. Drivers are up to date?
If that doesn't work then it could be a limitation of the card and it may not allow three monitors.

I'm beggining to think it might be the MB. I couldn't get the onboard GPU to work with a GT520 or a Saphire Radeon 6950, which is why I went out and bought another GT520. Whichever card is in the first PCIe slot seems to be the one that works. I have another MB here so I may bite the bullet and switch it out and see what happens. This is a new build and I can't say it's gone very smoothly unfortunately.

Thanks for you help!

Sometimes it takes a little bit longer to get things right and multiple monitors is something that there is not a lot of info on with all the different parts involved.

So both cards do work?

Is there something in the bios that has turned off the second PCIe 16x slot? Do you have any other cards in there?

I tried every permutation of setting in the bios related tot he PCIe slots. There wasn't an option to turn them off, but there was to switch one of them between 2x and 4x modes.

Any way, I switched out the MB to a Gigabyte Z68XP-UD3 and now both cards are working fine. Guess ASUS can have their MB back!
