First of all, you should reinstall drivers, and download them from the Nvidia's website.
Second, Check that the SLI option is enabled, just like fellow IronWill stated.
Thirdly, check your motherboard specs. Is your SLI running at good speeds? The recommended minimum for a SLI is x8/x8. You might be running x8/x4 or even worse. Also, some cheaper motherboards tend to share bandwidth between the second PCI-E slot, and the other PCI slots.
And last and maybe least, check that your CPU is not bottlenecking. You have an 930 so it is probably not the case, but you can check, anything is possible.
Checked all of these.
1.) Newest drivers are installed from Nvidia's website, the 275.33 drivers
2.) SLI is enabled in the Nvidia Control Panel
3.) Motherboard is an EVGA X58 SLI LE - The cards are running in the x16 and x8 slots.
Perhaps it's my SLI Bridge Connector that's not functioning?
