PC not identifying 2nd GTX 550 ti

[pewpewmerica]

I have recently upgraded my PC by buying a 2nd GTX 550 ti. After installing it, I found out that my PC was not recognizing the second card. I have tried everything, from updating the drivers to swapping the cards on the motherboard.

Any help?

Specs: intel i7 2600

            asus P8P67 EVO 

           8gb 1333mhz ram

            500watt power supply

           dual gtx 550 ti

i think that a 500W psu is a cutting it a bit fine in terms of a PSU.

Have you checked each card works individually? it could be you got a dead second 550ti

update the BIOS would be my next step

We tried both, they both work

But you might be right about the psu issue :C

the gtx 550ti has a tdp of 110 W more or less, so at least it should start even with a 500 psu i guess!

things to check:

SLI bridge connection;

driver activation (I don't know for nvidia drivers, but in the ati's you must activate the crossfire configuration);

psu cables connection

maybe a bios activation too

 

these may sound stupid but sometimes stupid checks are forgotten

 

anyway, can you see both the cards in the control panel (section: device manager i guess)?

That was one of the first things I checked and it wasn't there D:

I think i went through everything I could, but I'll doublecheck again

How can I tell if I've installed the bridge correctly?

[Gugos]

well it just must slide in till the end of the connector, there's not a right direction, so you can't put it in a wrong way, is just a passive connection

[airdeano]

in the NVidia control panel does it recognize both cards without SLI bridge

installed? should show both cards present and which card carries the monitor.

 

if not, do a clean reinstall GPU driver (both cards installed without bridge) and

monitor connected to first GPU. are you using DVI or HDMI cable?

 I'm using DVI

What do you mean by Driver Activation?

Have you looked in the nvidia control panel? If the second card is detected there will be an option that appears that allows you to activate sli. It will be a tab over on the left that says sli settings, under that tab there will be an option to "maximize 3d performance" or enable sli.
