Hi, crazycat, interesting point about the temperature.
System temp is currently 27c but goes to around 35c.
I originally had the GPU in the upper most PCIe slot and the TBS6925 in the lower most slot (with there being 4-5 empty slots in between them) so I wouldnt have thought the GPU's heat would have been an issue given they are as far away from each other as possible and its a fairly well ventilated case.
However, since I've had the replacement card, I've installed a 2nd video card which I've had to place directly above the TBS card so the GPU is blowing hot air on to it. I suppose on one hand you could argue that could be causing problem, but realistically even if the GPU is blowing 50c of air on to the back of it, the 6925 should be able to operate correctly at temperatures up to 50c surely?
Its an interesting theory, but I think more and more people would have had this issue if it was a simply temperature problem (which is not extreme by any measures) and it doesnt exactly explain why the 1st 6925 had to be returned.
Maybe support can confirm if a GPU seated near the 6925 blowing 50c on to it is enough for the tuner to malfunction.
