I joined this forum to simply troubleshoot a problem I have been having. I want to make sure I have the most recent updated drivers and software for my card(s). My toshiba Satellite L755D came with a dual card system (Radeon Hd 6620G +HD 7450M) that has crossfire on a quad core processor. When I tried to auto detect software it said my video adapters were not compatible and I had to contact Toshiba for an update. I found their latest driver for my laptop and installed it no problem. My concern is it's over a year old. I am very uneducated when it comes to video card systems, because it's a dual card system, even more so. Have I done the latest update already or can I get the latest on the AMD website, if so which supports my cards? Thanks for any insight you the reader may have. If you need info on my system I can post that later. Thank you.
