You can, but if the scene doesn't use more than 2GB VRAM.

Check only with Titans - how much VRAM is being used. You'll have the answear.

Maybe that was his issue, but what you can clearly see in the screenshot, that the
temperature values aren't listed in the correct order. It's a minor Bug but this
is also true with the latest version I use 2.12.2.

ok, i use only the two titans for check the render preview.
But can i turn on every cards when i run the final render ? Or it's the same problem ?

thank you Derya for the answer about the bug diplay of card temperature ;)

that would be the same - if the final scene uses more than 2GB of memory.
you could still use the card for display purposes...
