just gonna have to wait for a new bios update....same situation but different 3000 chip....same issues.....seems to be a common issues with this board and bios...theres a way to get the timings set correctly with the proper ram speed but once you power off the pc, and turn it back on you're greeted with the c5 error...and dont bother with the docp setting,,,,broke as well...you can set the ram frequency to whatever speed your sticks can handle but the timings are so loose i dont think its really worth it but the pc will boot with just that setting being messed it.....i know this doesn't help much but you're not alone in this mess.
