Yes, unless a stick of RAM fried in your latest attempt to boot with incorrect RAM settings. That's why I posted a link to the troubleshooting sticky. It most certainly applies to you. Have you tried getting the system to start with each stick of RAM installed by itself? The first thing I would do is reset the CMOS again and then try booting with each stick of RAM by itself. If it starts again, manually set the RAM values and you should be good to go.
I know you think your problem is special in some way, but a no-boot problem is a no-boot problem. That's what the checklist was created to troubleshoot.
