Mining with SLI

[FreePls]

When i do mining, should i keep the SLI connector or do i have to remove it? i want to use both cards to double up the rate, or is it enough to turn SLI off in the GPU menue?

If i run 2 instances in guiminer one with gpu 0-0 and one with gpu 0-1 slot then both have the exact hashrate ( +- 2 mh/s ) but i am not sure if its correct or if only one card is mining with sharing the work with the other card

You shouldn't need the SLI connector.
One instance of cgminer is enough.
Not sure about guiminer.

I've mined with my old NVIDIA cards which were connected with the SLI connector for ages.

First it was bitcoin, and then it was litecoin.

You don't need to remove the SLI connector, or usually do anything at all. If your mining program only recognizes one card, just disable SLI in the nVidia control panel.

But, you should not even have to do that. CudaMiner doesn't care if SLI is enabled or not. If both cards are recognized, you're good to go.
