Now I know 2.0 is *technically* supposed to be backward compatible with 1.0 on paper, but has anyone actually tried this successfully? I'm asking because I just bought an HD 5770 and the card appears to be DOA, but before I submit for an RMA, I was wondering if the fact that my board only supports x16 v1.0 could possibly have anything to do with it. I've been needing to upgrade my mobo for a while now, anyway, so I think this might be a good opportunity to do so. Has anyone had any problems like this in the past?
My board is the ASRock Wolfdale1333-D667 which uses the 945GC chipset. I was planning on upgrading to a P45 board, maybe the ECS BLACK SERIES P45T-A.
Update: This thread died without a definitive answer. I went ahead and bought the ECS board linked above, and the new card worked fine. The old ASRock board actually did have PCIe 2.0 slots, but for whatever reason, they didn't play nice with the 5770. I think it may have been due to the board already having an on-board video chipset. So if anyone else is having similar problems with several cards appearing to be DOA, try a new board. Worked for me, but as always YMMV.
