Any luck yet?
I'm getting the exact same RAM and MB as you have. The RAM is not on the list of compatible DIMMs on Asrock's site for the MB, so I am concerned it may either not work or have some other problems. I hope that's not the case.
Still no luck. I have tried to power up using only this with no luck
- PSU, mobo, videocard, RAM
Also tried swapping CMOS battery
But you are definitely right in that it may be the RAM. I don't know how I can check it - will the mobo still power on without anything attached?
