GTX280 Memory died (but which one?)

[smogsy]

I have GTX280 SLI and last few days soon as i turn on the computer the screen has red lines randomly going from top to bottom on the screen (not the whole screen)

my question is:

how can i tell which graphics card is dyeing as i'm in a SLI configuration of 2x280GTX

take one out, and test.

was hoping there was going to be a easier way there a dog to get in/out

Disable SLI, then disable each in turn through device manager, rebooting each time to test (switching the DVI lead obviously).

Shouldn't need to remove them then.
