I have pc3500 in this rig and cant get 190 fsb stable at any ratio,1:1,3:3,6:6. I have tried everything I know. I upped the core to 1.8 the ram to 2.8 and still nothing. I relaxed the timings, went from cas2 to 2.5. I dont know what else to do. Should I up the northbridge volts? Should I just RMA it and get corsair? Its the first rig in my sig.
