Problems with nvidia 460s going into SLI

[Sounoriginal]

Okay so I've seen a lot of people posting this problem but most of them was due to the fact the memory was off. well this time i have to nvidia 460 1GB each, they are the same card, bought at the same time, on GPU-Z everything is the same but the slots they are in.
one being in PCI-E x16 @16 and the other PCI-E x16 @4, would that cause me to not enable SLI?

That shouldn't matter. You might need to enable it in the control panel if you haven't done so already.

thats the issue im running into, the first time you set up SLI hardware, windows should either pop up a message with the nvidia control panel, but im not getting anything at all, is there a way to test the bridge?

 

[rene13cross]

Have you checked in the Nvidia control panel whether it show the 2 cards?

Nvidia is showing both nvidia 460s under the physX config tab, and I know when nvidia detects SLI that same tab is suppose to change names.

It should look something like that. Do you have that "Maximise 3D Performance" option?

If you are not given that SLI option in the driver then it could mean that Nvidia SLI is simply not supported by your motherboard. Can you verify that your motherboard actually supports Nvidia SLI (not just AMD Crossfire)?

No im getting this

no i cant verify my motherboard supporting SLI, I thought that if it supported Crossfire it should also be able to support Crossfire.

Is the SLI bridge fitted? Try flipping it upside down.

 

[rene13cross]

That usually means that SLI is not supported by your system (i.e. motherboard). Verify that the motherboard you're using supports Nvidia SLI.

So even though a motherboard says it supports Crossfire it doesnt also support SLI?

 

[rene13cross]

no i cant verify my motherboard supporting SLI, I thought that if it supported Crossfire it should also be able to support Crossfire.

No, unfortunately that's an incorrect assumption. They are 2 completely separate technologies. What model is your motherboard?

Asus M5A97 R2.0

Asus M5A97 R2.0

No Nvidia SLI support with that motherboard. Sorry.

Scroll down to "Multi-GPU support": http://www.asus.com/Motherboards/AMD_AM3Plus/M5A97_R20/#specifications

Oh but it does! Xfire will do x16 + x16, x16 + x8 and x16 + x4 but SLi will only do x8 + x8 or x16 + x16.
