I have an X1950XT running 6.10 cats and ATItool 0.26. The problem I am getting is that it doesn't seem to detect my x1950 but another non-existent graphics card: I have only had this issue since I upgraded my motherboard to a DFI RD600 and installed windows on a new hdd. I have tried 7.4, 7.3 and 6.10 cats and have had it working before on 6.10's and 7.3's on my old motherboards. I have also tried reinstalling windows and have tried the 0.27 beta. Am I over-looking a common problem here or is it something different? Anyway's I'm out of ideas other than the rd600 chipset conflicts with atitool thanks for any help.
