Hi guys I've been building SLI rigs usign this motherboard all year, using same memory and cpu configuration (phenom 9550) The last 6 out 10 motherboards I have ordered in (different suppliers) the computer will not boot. I have changed ever single component on the pc, inc the PSU. The fans spin and thats it. The motherboards I did manage to get working where not straight forward I would have to mess around with the memory settings in bios for it to recognise all 6 or 8gb ram. Then all of a sudden it would jsut work with restored defaults. I am a system builder and have 3 unit to go out to customers and time is ticking lol. Has anyone else experienced any problems with these boards. I have never had problems with them until Asrock stopped makign them anymore.
